abstract = {We propose a sampling-based Bayesian t test that allows researchers to quantify the statistical evidence in favor of the null hypothesis. This Savage-Dickey (SD) t test is inspired by the Jeffreys-Zellner-Siow (JZS) t test recently proposed by Rouder, Speckman, Sun, Morey, and Iverson (2009). The SD test retains the key concepts of the JZS test but is applicable to a wider range of statistical problems. The SD test allows researchers to test order restrictions and applies to two-sample situations in which the different groups do not share the same variance.},

This study evaluated the depression screening abilities of three questionnaires and one observer-rated scale in 202 consecutive patients 1 month after they experienced their first-ever ischemic stroke. At their respective optimum cutoff values, the sensitivity of the self-rated scales varied between 80% and 90%, while the specificity was about 60%. For the observer-rated scale (Hamilton Depression Rating Scale), sensitivity was 78.1%, and specificity was 74.6%. The instruments clearly performed better in men than in women. Despite this difference, it was concluded that all scales were acceptable screening instruments for poststroke depression.},

The immense scale of these experiments is unprecedented, involving thousands of samples and up to a million variables. The careful execution of exploratory data analysis (EDA) prior to the actual genotype-phenotype association analysis is crucial as this identifies problematic samples and poorly assayed genetic polymorphisms that, if undetected, can compromise the outcome of the experiment. EDA of such large-scale genetic data sets thus requires specialized numerical and graphical strategies, and this article provides a review of the current exploratory tools commonly used in GWAS.},

unidimensional models do not hold. The current work pursues posterior predictive model checking as a tool for criticizing models due to unaccounted for dimensions in data structures that follow conjunctive multidimensional models. These pursuits are couched in previous work investigating factors influencing dimensionality and dimensionality assessment. A simulation study investigates the model checking tools in the context of item response theory for dichotomous observables, in which a unidimensional model is fit to data that follow a conjunctive multidimensional model. Key findings include (a) support for the hypothesized effects of the manipulated factors and (b) the superiority of certain discrepancy measures for conducting posterior predictive model checking for dimensionality assessment.},

title = {From QTL to candidate gene: a genetic approach to alcoholism research},
abstract = {A major focus of research in alcohol-related disorders is to identify the genes and pathways that modulate alcohol-seeking behavior. In light of this, animal models have been established to study various aspects of alcohol dependence. The selectively bred alcohol-preferring (P) and -nonpreferring (NP) lines were developed from Wistar rats to model high and low voluntary alcohol consumption, respectively. Using inbred P and NP strains, a strong QTL (LOD-9.2) for alcohol consumption was identified on rat chromosome 4. To search for candidate genes that underlie this chromosomal region, complementary molecular-based strategies were implemented to identify genetic targets that likely contribute to the linkage signal. In an attempt to validate these genetic targets, corroborative studies have been utilized including pharmacological studies, knock-out/transgenic models as well as human association studies. Thus far, three candidate genes, neuropeptide Y (Npy), alpha-synuclein (Snca), and corticotrophin-releasing factor receptor 2 (Crhr2), have been identified that may account for the linkage signal. With the recent advancements in bioinformatics and molecular biology, QTL analysis combined with molecular-based strategies provides a systematic approach to identify candidate genes that contribute to various aspects of addictive behavior.},

abstract = {OBJECTIVE: To assess the factorial structure and construct validity for the Chinese version of the Modified Dental Anxiety Scale (MDAS). MATERIALS AND METHODS: A cross-sectional survey was conducted in March 2006 from adults in the Beijing area. The questionnaire consisted of sections to assess for participants' demographic profile and dental attendance patterns, the Chinese MDAS and the anxiety items from the Hospital Anxiety and Depression Scale (HADS). The analysis was conducted in two stages using confirmatory factor analysis and structural equation modelling. Cross validation was tested with a North West of England comparison sample. RESULTS: 783 questionnaires were successfully completed from Beijing, 468 from England. The Chinese MDAS consisted of two factors: anticipatory dental anxiety (ADA) and treatment dental anxiety (TDA). Internal consistency coefficients (tau non-equivalent) were 0.74 and 0.86 respectively. Measurement properties were virtually identical for male and female respondents. Relationships of the Chinese MDAS with gender, age and dental attendance supported predictions. Significant structural parameters between the two sub-scales (negative affectivity and autonomic anxiety) of the HADS anxiety items and the two newly identified factors of the MDAS were confirmed and duplicated in the comparison sample. CONCLUSION: The Chinese version of the MDAS has good psychometric properties and has the ability to assess, briefly, overall dental anxiety and two correlated but distinct aspects.},

They aim to control either the family-wise error rate (FWER) or the false discovery rate (FDR) at a level no greater than the uncorrected critical p-value. smileplot calls multproc and then creates a smile plot, with data points corresponding to estimated parameters, the p-values (on a reverse log scale) on the y-axis, and the parameter estimates (or another variable) on the x-axis. There are y-axis reference lines at the uncorrected and corrected overall critical p-values. The reference line for the corrected overall critical p-value, known as the parapet line, is an informal ``upper confidence limit'' for the set of null hypotheses that are true and defines a boundary between data mining and data dredging. A smile plot summarizes a set of multiple analyses just as a Cochrane forest plot summarizes a meta-analysis.},

The varying role of impulsivity--a trait related to disinhibition, approach motivation, novelty seeking, and sensation seeking--in successive self-report measures of this model, including the Eysenck Personality Inventory (EPI) and Eysenck Personality Questionnaire (EPQ), is described. It is argued that certain findings in experimental, cross-sectional, and longitudinal research using these measures point to the importance of impulsivity as a temperamental vulnerability factor for substance use.},

title = {The 12-item World Health Organization Disability Assessment Schedule II (WHO-DAS II): a nonparametric item response analysis},
abstract = {ABSTRACT: BACKGROUND: Previous studies have analyzed the psychometric properties of the World Health Organization Disability Assessment Schedule II (WHO-DAS II) using classical omnibus measures of scale quality. These analyses are sample dependent and do not model item responses as a function of the underlying trait level. The main objective of this study was to examine the effectiveness of the WHO-DAS II items and their options in discriminating between changes in the underlying disability level by means of item response analyses. We also explored differential item functioning (DIF) in men and women. METHODS: The participants were 3615 adult general practice patients from 17 regions of Spain, with a first diagnosed major depressive episode. The 12-item WHO-DAS II was administered by the general practitioners during the consultation. We used a non-parametric item response method (Kernel-Smoothing) implemented with the TestGraf software to examine the effectiveness of each item (item characteristic curves) and their options (option characteristic curves) in discriminating between changes in the underliying disability level. We examined composite DIF to know whether women had a higher probability than men of endorsing each item. RESULTS: Item response analyses indicated that the twelve items forming the WHO-DAS II perform very well. All items were determined to provide good discrimination across varying standardized levels of the trait. The items also had option characteristic curves that showed good discrimination, given that each increasing option became more likely than the previous as a function of increasing trait level. No gender-related DIF was found on any of the items. CONCLUSIONS: All WHO-DAS II items were very good at assessing overall disability. Our results supported the appropriateness of the weights assigned to response option categories and showed an absence of gender differences in item functioning.},

abstract = {The ability of personality traits to predict im- portant life outcomes has traditionally been questioned because of the putative small effects of personality. In this article, we compare the predictive validity of personality traits with that of socioeconomic status (SES) and cogni- tive ability to test the relative contribution of personality traits to predictions of three critical outcomes: mortality, divorce, and occupational attainment. Only evidence from prospective longitudinal studies was considered. In addi- tion, an attempt was made to limit the review to studies that controlled for important background factors. Results showed that the magnitude of the effects of personality traits on mortality, divorce, and occupational attainment was indistinguishable from the effects of SES and cognitive ability on these outcomes. These results demonstrate the influence of personality traits on important life outcomes, highlight the need to more routinely incorporate measures of personality into quality of life surveys, and encourage further research about the developmental origins of per- sonality traits and the processes by which these traits in- fluence diverse life outcomes.},

abstract = {STUDY OBJECTIVE: To assess which indicators of socioeconomic status are associated with an increased prevalence of common mental disorders. DESIGN: Cross sectional household survey. SETTING: Santiago, Chile. PARTICIPANTS: Random sample of adults aged 16-65 residing in private households. Main results: Less education (odds ratio 2.44, 95% confidence intervals 1.50 to 3.97), a recent income decrease (odds ratio 2.14, 1.70 to 2.70), and poor housing (odds ratio 1.53, 1.05 to 2.23), were the only socioeconomic status variables that remained significantly associated with an increased prevalence of common mental disorders after adjustments. The prevalence of common mental disorders was also higher among people with manual unskilled occupations, overcrowded housing, and lower per capita income but these associations disappeared after adjustment for other explanatory and confounding variables. CONCLUSIONS: There is a strong, inverse, and independent association between education and common mental disorders. However, income was not associated with the prevalence of common mental disorders, after adjusting for other socioeconomic variables. Similar results have been found in other Latin American studies but British studies tend to find the opposite, that income but not education is associated with common mental disorders. Understanding the impact of socioeconomic factors on mental health requires research in poor as well as rich countries.},

abstract = {Although federal initiatives have mandated broader inclusion of minorities in clinical research on diseases that have disparities in health by race and ethnicity, it is not clear whether these initiatives have affected reporting of trial results. The objective of this study was to examine the reporting of race/ethnicity in clinical trials reports in areas of known disparities in health (i.e., diabetes, cardiovascular disease, HIV/AIDS, and cancer) and to determine what factors were associated with reporting of race/ethnicity in results. We performed a Medline search covering the period January 1989 to Oct 2000 to identify clinical trials of diabetes, cardiovascular disease, HIV/AIDS, and cancer published in the Annals of Internal Medicine, JAMA, and New England Journal of Medicine. The main outcome measure was the reporting of participation and of results by race/ethnicity of trial participants. Of 253 eligible trials, 40% (n=102) were non race-focused yet did not report race, while 2% (n=4) were non gender-focused and did not report gender. Forty-six percent of trials that reported the race/ethnicity of the sample reported only one or two racial/ethnic categories, and in 43% of these trials the total number of individuals reported in each race/ethnicity category did not equal the total reported sample size. Analysis of results by race/ethnicity was reported in only two trials, and by gender in only three trials. In diseases with known racial and ethnic disparities, many clinical trials do not report the race/ethnicity of the study participants, and almost none report analyses by race/ethnicity. Although federal initiatives mandate inclusion of minority groups in research, that inclusion has not translated to reporting of results that might guide therapeutic decisions.},

title = {A modular approach for integrative analysis of large-scale gene-expression and drug-response data},
abstract = {High-throughput technologies are now used to generate more than one type of data from the same biological samples. To properly integrate such data, we propose using co-modules, which describe coherent patterns across paired data sets, and conceive several modular methods for their identification. We first test these methods using in silico data, demonstrating that the integrative scheme of our Ping-Pong Algorithm uncovers drug-gene associations more accurately when considering noisy or complex data. Second, we provide an extensive comparative study using the gene-expression and drug-response data from the NCI-60 cell lines. Using information from the DrugBank and the Connectivity Map databases we show that the Ping-Pong Algorithm predicts drug-gene associations significantly better than other methods. Co-modules provide insights into possible mechanisms of action for a wide range of drugs and suggest new targets for therapy.},

After some brief comments on classical test theory, the paper provides a practical framework for structuring an RG study, including: (1) test selection with an eye toward frequency of test use and reporting practices by authors; (2) development of a coding sheet that will capture potential variation in score reliability across studies; (3) procedural recommendations regarding data collection; (4) identification and use of potential dependent variables; and (5) application of general linear model analyses to the data.},

Participants were 270 children (male: 161, female: 109; age 7.74+/-0.81 years). The association between DCD status identified by each of the motor tests and psychosocial problems measured by the Child Behavioral Checklist-Chinese version (CBCL-C) was examined using multiple logistic regressions. The results showed that DCD identified by the BOTMP was associated with high scores on the Withdrawn and Social Problems, with a higher proportion of females identified. DCD identified by the MABC was associated with high scores on the Withdrawn and Attention Problems and low score on the Aggressive Behavior. The results reaffirmed the lack of consistency between the motor tests and indicated that children identified by the two motor tests showed different profiles of attention and psychosocial adjustment.},

title = {An evaluation of non-response bias in peer, self and teacher ratings of children's psychological adjustment},
abstract = {The last decades have shown a rapid increase in nonresponse rates. For this reason it is important to study nonresponse and think about it critically. In this article we investigated whether nonresponse affected estimates of the levels of adjustment problems in children and the correlations between these outcomes. The nonresponse was caused by parents who refused permission to interview their children at school, parents who did not return a questionnaire, teachers who did not complete the questionnaire, and parents who refused to participate in an in-depth study, with nonresponse rates of 9%, 69%, 25%, and 46% respectively. The sample consisted of 1282 children aged 4-5 years and the dependent measures were peer-rated sociometric status, self-rated wellbeing at school, and teacher-rated behaviour problems. Despite considerable nonresponse in some conditions our results showed hardly any evidence for bias. This suggested that bias cannot simply be inferred from the amount of nonresponse and that standard rules such as nonresponse rates higher than 50 % are not acceptable lack a scientific basis. Instead, we argue that to assess nonresponse bias the specific conditions and analyses of the study will need to be considered and special measures may be required.},

abstract = {Previous work has shown a relationship between brain anatomy and how quickly adults learn to perceive foreign speech sounds. Faster learners have greater asymmetry (left>right) in parietal lobe white matter (WM) volumes and larger WM volumes of left Heschl's gyrus than slower learners. Here, we tested native French speakers who were previously scanned using high-resolution anatomical magnetic resonance imaging. We asked them to pronounce a Persian consonant that does not exist in French but which can easily be distinguished from French speech sounds, the voiced uvular stop. Two judges scored the goodness of the utterances. Voxel-based morphometry revealed that individuals who more accurately pronounce the foreign sound have higher WM density in the left insula/prefrontal cortex and in the inferior parietal cortices bilaterally compared with poorer producers. Results suggest that WM anatomy in brain regions previously implicated in articulation and phonological working memory, or the size/shape of these or adjacent regions, is in part predictive of the accuracy of speech sound pronunciation.},

title = {Application of stochastic measurement models to visual function rating scale questionnaires},
abstract = {PURPOSE: To test hypotheses that low vision patient responses to visual function rating scale questionnaires conform to an additive conjoint structure and that the Likert score is a sufficient statistic for the latent patient trait; to compare results for two competing stochastic measurement models; and to determine if different questionnaires measure the same construct in low vision patients. METHODS: Visual function rating scale questionnaires were administered to 284 low vision subjects by telephone. Each subject was administered two of four questionnaires: ADVS, NEI VFQ-25 plus supplement, expanded VAQ, and VF-14. RESULTS: Data were analyzed with the Muraki item response model and the Andrich measurement model. The estimates of latent person, item, and response threshold measures from the two models are linearly related. The Muraki model produced a better overall fit to the item response data, the Andrich model produced a better fit to the average ratings for each person and item. Fit statistics for the Andrich model were proportional to the item-dependent discrimination parameter in the Muraki model. The ADVS was the most accurate measure and the NEI VFQ was the least. Reliability was similar for all four instruments. Person measures for each pair of instruments were linearly related indicating that all four instruments measured the same construct. The person measure estimate from the Andrich model is monotonic with the average rating. That relationship suggests a transformation of the Likert score that can correct the floor and ceiling effects in rating scale data. CONCLUSIONS: Patient responses to all four questionnaires conform to varying degrees to an additive conjoint structure. The Likert score is a sufficient statistic for the ADVS and the VAQ, but not for the NEI VFQ or VF-14. All four instruments measure the same construct in the low vision population, but they differ in measurement accuracy and precision.},

abstract = {BACKGROUND: In contrast to quality of life, patient satisfaction on chronic haemodialysis (HD) and peritoneal dialysis (PD) has only rarely been studied. PATIENTS AND METHODS: All chronic HD and PD patients of the 19 centres located in western Switzerland were asked to complete a specific questionnaire, assessing dialysis centre characteristics, treatment modalities, and information received before and during dialysis treatment. Comparison between satisfaction with PD and HD was carried out on the patients in the nine centres offering both treatment modalities. RESULTS: Of the 558 questionnaires distributed to chronic HD patients, 455 were returned (response rate 82%). Fifty of 64 PD patients (78%) returned the questionnaire. The two groups were similar in age, gender, and duration of dialysis treatment. Completion rates were >90% for a majority of questions, with the lowest rate for information on sexuality (49% in HD and 54% in PD respectively). The lowest scores were recorded for information received about complications and costs of dialysis, and impact of end-stage kidney disease on sexuality. Satisfaction was lower in anonymous questionnaires. Satisfaction of PD patients was significantly better in 50% of the questions, particularly session tolerance (p<0.001), information about dialysis sessions (p=0.007), and complications (p=0.006). CONCLUSIONS: PD patients were on average more satisfied with their treatment than HD patients. Satisfaction could be improved with more information about potential adverse treatment effects.},

Increases over time in the frequency of these disorders (to present rates of about 60 cases per 10,000 children) might be attributable to factors such as new administrative classifications, policy and practice changes, and increased awareness. Surveillance and screening strategies for early identification could enable early treatment and improved outcomes. Autism spectrum disorders are highly genetic and multifactorial, with many risk factors acting together. Genes that affect synaptic maturation are implicated, resulting in neurobiological theories focusing on connectivity and neural effects of gene expression. Several treatments might address core and comorbid symptoms. However, not all treatments have been adequately studied. Improved strategies for early identification with phenotypic characteristics and biological markers (eg, electrophysiological changes) might hopefully improve effectiveness of treatment. Further knowledge about early identification, neurobiology of autism, effective treatments, and the effect of this disorder on families is needed.},

title = {Brief, personality-targeted coping skills interventions and survival as a non-drug user over a 2-year period during adolescence},
abstract = {CONTEXT: Selective interventions targeting personality risk are showing promise in the prevention of problematic drinking behavior, but their effect on illicit drug use has yet to be evaluated. OBJECTIVE: To investigate the efficacy of targeted coping skills interventions on illicit drug use in adolescents with personality risk factors for substance misuse. DESIGN: Randomized controlled trial. SETTING: Secondary schools in London, United Kingdom. PARTICIPANTS: A total of 5302 students were screened to identify 2028 students aged 13 to 16 years with elevated scores on self-report measures of hopelessness, anxiety sensitivity, impulsivity, and sensation seeking. Seven hundred thirty-two students provided parental consent to participate in this trial. INTERVENTION: Participants were randomly assigned to a control no-intervention condition or a 2-session group coping skills intervention targeting 1 of 4 personality profiles. MAIN OUTCOME MEASURES: The trial was designed and powered to primarily evaluate the effect of the intervention on the onset, prevalence, and frequency of illicit drug use over a 2-year period. RESULTS: Intent-to-treat repeated-measures analyses on continuous measures of drug use revealed time x intervention effects on the number of drugs used (P < .01) and drug use frequency (P < .05), whereby the control group showed significant growth in the number of drugs used as well as more frequent drug use over the 2-year period relative to the intervention group. Survival analysis using logistic regression revealed that the intervention was associated with reduced odds of taking up the use of marijuana (beta = -0.3; robust SE = 0.2; P = .09; odds ratio = 0.7; 95% confidence interval, 0.5-1.0), cocaine (beta = -1.4; robust SE = 0.4; P < .001; odds ratio = 0.2; 95% confidence interval, 0.1-0.5), and other drugs (beta = -0.7; robust SE = 0.3; P = .03; odds ratio = 0.5; 95% confidence interval, 0.3-0.9) over the 24-month period. CONCLUSION: This study extends the evidence that brief, personality-targeted interventions can prevent the onset and escalation of substance misuse in high-risk adolescents.

We extend theoretical models of data graphics to include such transitions, introducing a taxonomy of transition types. We then propose design principles for creating effective transitions and illustrate the application of these principles in DynaVis, a visualization system featuring animated data graphics. Two controlled experiments were conducted to assess the efficacy of various transition types, finding that animated transitions can significantly improve graphical perception.},

title = {Estimating Ideological Positions of Candidates and Contributors from Campaign Finance Records},
abstract = {Many applications in political science require reliable ideological measures of individuals and groups. Methods designed to recover ideological estimates from roll call votes have been highly successful in providing precise estimates of ideologi- cal positions but can only recover estimates for legislators with voting records. In contrast, methods for scaling political texts show great promise in extending estima- tion outside the confines of legislative bodies but are not yet able to locate individu- als with much precision. This paper presents an item response model to recover ideological estimates from campaign finance records. Scaling campaign finance data offers an attractive middle ground between the aforementioned scaling methods. The method recovers ideological positions for incumbents that strongly correlate with NOMINATE scores, while simultaneously recovering reliable positions for thousands of individuals and groups outside of Congress, including political action committees (PACs) and unsuccessful challengers and open-seat candidates for whom we never observe a voting record. I illustrate the method by assessing com- peting hypotheses about which motivations best explain the contribution behavior of PACs. I find that ideology features prominently in the contribution behavior of PACs, but its influence varies considerably across categories of PACs in a predicta- ble manner.},

title = {A tutorial on Multi-Block Discriminant Correspondence Analysis (MUDICA): A new method for analyzing discourse data from clinical populations},
abstract = {Purpose. In communication disorders research, we frequently describe clinical groups based on patterns of performance, but we often study only few participants described by many quan- titative and qualitative variables. These data are difficult to handle by standard inferential tools (e.g., ANOVA or factor analysis) whose assumptions are unfit for these data. This paper presents Multi-block Discriminant Correspondence Analysis (MUDICA) which is a recent method that can handle datasets not suited for standard inferential techniques.
Method.	M U D I C A	is	illustrated	with	clinical	data	examining	conversational	trouble-source repair and topic maintenance in dementia of the Alzheimers type (DAT). Seventeen DAT parti- cipant/spouse dyads (6 control, 5 early DAT, 6 moderate DAT) produced spontaneous conversa- tions analyzed for co-occurrence of trouble-source repair and topic maintenance variables.
Results. MUDICA found that trouble-source repair sequences and topic transitions are associ- ated and that patterns of performance in the DAT groups differed significantly from the CTRL group.
Conclusions. MUDICA is ideally suited to analyze language and discourse data in communi- cation disorders because it (1) can identify and predict clinical group membership based on patterns of performance, (2) can accommodate few participants and many variables, (3) can be used with categorical data, and (4) adds the rigor of inferential statistics.},

title = {[Validity of the BVAQ: a study in eating disorder patients and controls]},
abstract = {Alexithymia core features are the difficulties in identifying and describing feelings; the difficulties in distinguishing feelings from the bodily sensations of emotional arousal; an impaired symbolization, as evidenced by a paucity of fantasies and other imaginative activity; and a tendency to focus on external events rather than inner experience. Several measures of alexithymia have been developed, including interviewer-rated questionnaires and self-report questionnaires. Among the self-report questionnaires, the 20-item Toronto Alexithymia scale (TAS-20) is the most commonly used, but it fails to measure all the core features of alexithymia. A recently developed instrument, the Bermond-Vorst Alexithymia Questionnaire (BVAQ), allows the measurement of the alexithymia core features, as well as an additional one. It appeared to present good psychometric properties, notably the abbreviated BVAQ-form B. The results of recent studies comparing the psychometric properties of the TAS-20 and the BVAQ have recommended the BVAQ over the TAS-20. However, this questionnaire needed further validation. OBJECTIVES: Thus, the aim of the present study was to determine the convergent, discriminant and concurrent validity of the Bermond-Vorst Alexithymia Questionnaire -- form B (BVAQ-B) in a clinical sample of 59 eating disorder patients, as well as in 191 controls. The TAS-20 constituted the gold standard for the assessment of the BVAQ-B' convergent validity. To compare the concurrent validity of the BVAQ-B and the TAS-20, participants also completed several self-reports investigating different dimensions of emotion regulation capacities: the 13-item Beck Depression Inventory (BDI), the Spielberger State and Trait Anxiety Inventory (STAI-form Y), as well as the Chapman and Chapman Physical and Social Anhedonia Scales (PAS and SAS). One way analyses of variance were used for mean scores comparisons. Convergent validity was determined using Pearson coefficients of correlation. RESULTS: Results of the analyses suggested the BVAQ-B has a satisfying convergent and discriminant validity. This was observed in both the clinical and control samples. Moreover, the comparison of the convergent validity of the BVAQ-B and the TAS-20 revealed several differences between these two alexithymia self-report questionnaires. The BVAQ-B appeared less sensitive to the subjective emotional state of the participants than the TAS-20. Whereas it was argued the TAS-20 overlaps with other emotional state scores, the BVAQ-B would allow to measure alexithymia more specifically. In addition, the present results allowed to further determine the relations between alexithymia and other dimensions of emotion regulation capacities. The analyses confirmed that alexithymia is linked to other emotion regulation dimensions such as depression and anxiety. Moreover, alexithymia was associated with physical and social anhedonia, two dimensions that received less interest in the alexithymia literature to date. This study also showed that control and clinical sample have different emotion regulation capacities. Eating disorder patients were not only more alexithymic and more depressed, but also more anxious and more anhedonic than the controls. Finally, this study revealed that alexithymia differs whether the alexithymic individuals are patients or controls. Healthy alexithymic individuals (ie, individuals categorized as alexithymic in the control group) seemed characterised by a selective deficit of emotional cognition, with sparing of emotional experience (Bermond's type II alexithymia). Alexithymics individuals of the eating -disorder group seemed particularly unabled to experience affect. This pattern could correspond to Bermond's type I alexithymia, which is characterised by the absence of emotional experience and, consequently, by the absence of the cognition accompanying the emotion. In summary, results of the present study add to the literature debating on whether alexithymia is similar in different types of population.},

abstract = {The objective of this study is to compare the cognitive profile, the motor and language functioning and the psychosocial adaptation of children with Asperger syndrome (AS) and with high-functioning autism (HFA). Subjects were recruited through the department Autism and Developmental Disorders of the Heckscher-Klinikum. To be included in the study, the full-scale-IQ had to be at least 80. Subjects with AS had to have a normal early language development and subjects with HFA a clear delay in language development, as reported by their parents. The sample consisted of 57 children with Asperger syndrome and 55 children with high-functioning autism. The mean age of the children was 10 years. All subjects were examined with a standardised test battery. Children with AS had a higher full-scale-IQ than children with HFA. This was due to a higher verbal-IQ. There were no significant differences in the performance-IQ. At a mean age of 10 years, subjects with AS had better language skills than subjects with HFA, but at least 30% showed clear receptive language problems. Motor problems were present in about 50% of the children with AS and HFA. The level of psychosocial adaptation was clearly reduced, but was comparable for the two groups. The differences in verbal-IQ and language skills between the two groups could be explained through the definition of the syndromes. The presence of language problems in the subjects with AS at age 10, the comparable degree of motor impairment and level of psychosocial adaptation question the validity of the distinction between AS and HFA within the category of pervasive developmental disorders.},

The Alzheimer's Disease Neuroimaging Initiative 1.5 T MRI and genetic dataset was investigated using voxel-based morphometry (VBM) and FreeSurfer parcellation followed by genome-wide association studies (GWAS). One hundred forty-two measures of grey matter (GM) density, volume, and cortical thickness were extracted from baseline scans. GWAS, using PLINK, were performed on each phenotype using quality-controlled genotype and scan data including 530,992 of 620,903 single nucleotide polymorphisms (SNPs) and 733 of 818 participants (175 AD, 354 amnestic mild cognitive impairment, MCI, and 204 healthy controls, HC). Hierarchical clustering and heat maps were used to analyze the GWAS results and associations are reported at two significance thresholds (p<10(-7) and p<10(-6)). As expected, SNPs in the APOE and TOMM40 genes were confirmed as markers strongly associated with multiple brain regions. Other top SNPs were proximal to the EPHA4, TP63 and NXPH1 genes. Detailed image analyses of rs6463843 (flanking NXPH1) revealed reduced global and regional GM density across diagnostic groups in TT relative to GG homozygotes. Interaction analysis indicated that AD patients homozygous for the T allele showed differential vulnerability to right hippocampal GM density loss. NXPH1 codes for a protein implicated in promotion of adhesion between dendrites and axons, a key factor in synaptic integrity, the loss of which is a hallmark of AD. A genome-wide, whole brain search strategy has the potential to reveal novel candidate genes and loci warranting further investigation and replication.},

Ease of use is provided through three primary mechanisms: (1) oper- ator and function over-loading, (2) numerous pre-fabricated utility functions, and (3) clear documentation and example programs. Additionally, Scythe is quite flexible and entirely extensible because the source code is available to all users under the GNU General Public License.},

abstract = {Although differential item functioning (DIF) theory traditionally focuses on the behavior of individual items in two (or a few) specific groups, in educational measurement contexts, it is often plausible to regard the set of items as a random sample from a broader category. This article presents logistic mixed models that can be used to model uniform DIF, treating the item effects and their interaction with groups (DIF) as random. In a similar way, the group effects can be modeled as random instead of fixed, if the groups can be considered a random sample from a population of groups. The models can, furthermore, be adapted easily for model- ing DIF over individual persons rather than over groups, or for modeling the dif- ferential functioning of groups of items instead of individual items. It is shown that the logistic mixed model approach is not only a comprehensive and economical way to detect these different kinds of DIF, it also encourages us to explore possible explanations of DIF by including group or item covariates in the model.},

abstract = {Major depression is more prevalent among individuals with alcoholism than in the general population. Twin studies have found a moderate degree of genetic correlation for alcohol dependence (AD) and major depression (MD), suggesting the existence of loci that confer susceptibility to both disorders. The aim of the present study was to conduct genome-wide linkage analyses to identify loci and to replicate prior evidence for linkage to MD, and to search for linkage regions that may confer risk to the co-occurrence of depression and alcoholism in a sample of sib-pairs affected with AD. A set of 1020 microsatellite markers (average marker spacing of 4cM) were genotyped in 1289 subjects, which consisted of 473 informative families for analysis of depressive traits and 626 sibling pairs for analysis of symptoms of MD and AD. For univariate linkage results for depression, there were six regions (1q, 2p, 4q, 12q, 13q, and 22q) with multipoint LOD scores in excess of 1.00; the highest peak was on chromosome 4q32.3 near marker D4S2952 (LOD=2.17, p=0.0008) for symptoms of MD. Bivariate linkage analysis of symptoms of MD and AD identified only one region at 22q11.21 with LOD>1, which overlapped with the region for symptoms of MD. Several of these regions replicate previously reported linkage results for major depression and emotion-related traits and events, such as neuroticism and suicide attempts. These identified genomic locations, together with results from prior studies, indicate potential regions of interests that may contain susceptibility loci to the risk of depression among individuals with alcohol dependence.},

We develop an approach to detecting DIF in the context of item response theory (IRT) models based on computing a diagnostic which is the posterior mean of a p-value. IRT models are fit in a Bayesian framework, and simulated proficiency parameters from the posterior distribution are retained. Monte Carlo estimates of the p-value diagnostic are then computed by comparing the fit of nonparametric regressions of item responses on simulated proficiency parameters and group membership. Some properties of our approach are examined through a simulation experiment. We apply our method to the analysis of responses from two separate studies to the BASIS-24, a widely used self-report mental health assessment instrument, to examine DIF between the English and Spanish-translated version of the survey.},

title = {Cluster Analysis of Genomic Data with Applications in R},
abstract = {In this paper, we provide an overview of existing partitioning and hierarchical clustering algorithms in R. We discuss statistical issues and methods in choos- ing the number of clusters, the choice of clustering algorithm, and the choice of dissimilarity matrix. In particular, we illustrate how the bootstrap can be em- ployed as a statistical method in cluster analysis to establish the reproducibility of the clusters and the overall variability of the followed procedure. We also show how to visualize a clustering result by plotting ordered dissimilarity matrices in R. We present a new R package, hopach, which implements the hybrid clustering method, Hierarchical Ordered Partitioning And Collapsing Hybrid (HOPACH). The methodology combines the strengths of both partitioning and agglomerative hierarchical clustering methods. At each node, a cluster is split into two or more smaller clusters with an enforced ordering of the clusters. Collapsing steps unit- ing the two closest clusters into one cluster are used to correct for errors made in the partitioning steps. The hopach function uses the median split silhouette (MSS) criterion to automatically choose (i) the number of children at each node, (ii) which clusters to collapse, and (iii) the main clusters (pruning the tree to pro- duce a partition of homogeneous clusters). The methodology is illustrated with gene expression data.},

title = {Population substructure in Finland and Sweden revealed by the use of spatial coordinates and a small number of unlinked autosomal SNPs},
abstract = {BACKGROUND: Despite several thousands of years of close contacts, there are genetic differences between the neighbouring countries of Finland and Sweden. Within Finland, signs of an east-west duality have been observed, whereas the population structure within Sweden has been suggested to be more subtle. With a fine-scale substructure like this, inferring the cluster membership of individuals requires a large number of markers. However, some studies have suggested that this number could be reduced if the individual spatial coordinates are taken into account in the analysis. RESULTS: We genotyped 34 unlinked autosomal single nucleotide polymorphisms (SNPs), originally designed for zygosity testing, from 2044 samples from Sweden and 657 samples from Finland, and 30 short tandem repeats (STRs) from 465 Finnish samples. We saw significant population structure within Finland but not between the countries or within Sweden, and isolation by distance within Finland and between the countries. In Sweden, we found a deficit of heterozygotes that we could explain by simulation studies to be due to both a small non-random genotyping error and hidden substructure caused by immigration. Geneland, a model-based Bayesian clustering algorithm, clustered the individuals into groups that corresponded to Sweden and Eastern and Western Finland when spatial coordinates were used, whereas in the absence of spatial information, only one cluster was inferred. CONCLUSION: We show that the power to cluster individuals based on their genetic similarity is increased when including information about the spatial coordinates. We also demonstrate the importance of estimating the size and effect of genotyping error in population genetics in order to strengthen the validity of the results.},

title = {Methodological standards in non-inferiority AIDS trials: moving from adherence to compliance},
abstract = {BACKGROUND: The interpretation of the results of active-control trials regarding the efficacy and safety of a new drug is important for drug registration and following clinical use. It has been suggested that non-inferiority and equivalence studies are not reported with the same quantitative rigor as superiority studies. METHODS: Standard methodological criteria for non-inferiority and equivalence trials including design, analysis and interpretation issues were applied to 18 recently conducted large non-inferiority (15) and equivalence (3) randomized trials in the field of AIDS antiretroviral therapy. We used the continuity-corrected non-inferiority chi-square to test 95% confidence interval treatment difference against the predefined non-inferiority margin. RESULTS: The pre-specified non-inferiority margin ranged from 10% to 15%. Only 4 studies provided justification for their choice. 39% of the studies (7/18) reported only intent-to-treat (ITT) analysis for the primary endpoint. When on-treatment (OT) and ITT statistical analyses were provided, ITT was favoured over OT for results interpretation for all but one study, inappropriately in this statistical context. All but two of the studies concluded there was "similar" efficacy of the experimental group. However, 9/18 had inconclusive results for non-inferiority. CONCLUSION: Conclusions about non-inferiority should be drawn on the basis of the confidence interval analysis of an appropriate primary endpoint, using the predefined criteria for non-inferiority, in both OT and ITT, in compliance with the non-inferiority and equivalence CONSORT statement. We suggest that the use of the non-inferiority chi-square test may provide additional useful information.},

abstract = {We consider the problem of selecting grouped variables (factors) for accurate predic- tion in regression. Such a problem arises naturally in many practical situations with the multi-factor ANOVA problem as the most important and well known example. Instead of selecting factors by stepwise backward elimination, we focus on estimation accuracy and consider extensions of the LASSO, the LARS, and the nonnegative garrote for factor selection. The LASSO, the LARS, and the nonnegative garrote are recently proposed regression methods that can be used to select individual variables. We study and propose efficient algorithms for the extensions of these methods for factor selection, and show that these extensions give superior performance to the traditional stepwise backward elimination method in factor selection problems. We study the similarities and the differences among these methods. Simulations and real examples are used to illustrate the methods.},

title = {Testing for Interaction in Binary Logit and Probit Models: Is a Product Term Essential?},
abstract = {Political scientists presenting binary dependent variable (BDV) models often offer hypotheses
that independent variables interact in their influence on the probability that an event Y occurs, Pr(Y). A consensus appears to have evolved on how to test such hypotheses: (i) estimate a logit or probit model including product terms to specify the interaction, (ii) test the hypothesis by determining whether the coefficients for these terms are statistically significant, and (iii) if they are, describe the nature of the interaction by estimating how the marginal effect of one independent variable on Pr(Y) varies with the value of the other independent variables. We contend that in the BDV context, statistically significant product term coefficients are neither necessary nor sufficient for concluding that there is substantively meaningful interaction among variables in their influence on Pr(Y). Even when no product terms are included in a logit or probit model, if the marginal effect of one variable on Pr(Y) is related to another independent variable then substantively meaningful interaction is present, and describing such interaction is essential to an accurate portrayal of the data generating process at work. We propose a strategy for studying interaction in the BDV context that is consistent with the recent emphasis in the discipline on casting hypotheses in terms of effects on the probability of an event's occurrence and reporting estimated marginal effects on this probability.},

abstract = {The purpose of this study was to determine whether Cloninger's revised 7-factor model of personality showed incremental validity over his four dimensions of temperament. A sample of 2517 Australian twins aged over 50 between 1993 and 1995 returned completed self-reported measures of Self-directedness, Cooperativeness, and Self-transcendence from Cloninger's Temperament and Character Inventory. Many of these twins had participated in a 1988 study containing Cloninger's temperament measures of Harm Avoidance, Novelty Seeking, Reward Dependence and Persistence. Contrary to theoretical expectations, univariate analyses revealed that familial aggregation for the character dimensions could be entirely explained by additive gene action alone. Although temperament explained 26, 37 and 10% of additive genetic variance in Self-directedness, Cooperativeness and Self-transcendence, respectively, seven genetic factors were required to explain the genetic variance among the TPQ dimensions, and almost all of the non-shared environmental variance was unique to each dimension of character. Our results indicate that the inclusion of all seven dimensions in a taxonomy of personality is warranted.},

Expectations for the regression coefficients from submodels omitting the h2 and c2 terms are derived. Model comparisons similar to those conducted using maximum-likelihood estimation procedures are illustrated using multiple regression. Submodels of the augmented DF model are shown to yield parameter estimates highly similar to those obtained from the traditional latent variable model. While maximum-likelihood estimation of covariance structure may be the optimal statistical method of estimating genetic and environmental parameters, the model-fitting approach we propose is a useful extension to the highly flexible and conceptually simple DF methodology.},

However, which effect size and how to interpret it are not yet clearly delineated. The present focus is on effect sizes indicating strength of correlation, that is, effect sizes that describe the strength of monotonic association between two random variables X and Y in a population. METHODS: A logical structure of measures of association is traced, showing the interrelationships among the many measures of association. Advantages and disadvantages of each are discussed. CONCLUSIONS: Suggestions are made for the future use of measures of association in research to facilitate considerations of clinical significance, emphasizing distribution-free effect sizes such as the Spearman correlation coefficient and Kendall's coefficient of concordance for ordinal versus ordinal associations, weighted and intraclass kappa for binary versus binary associations and risk difference (RD) for binary versus ordinal association.},

title = {Essay Assessment with Latent Semantic Analysis},
abstract = {Latent semantic analysis (LSA) is an automated, statistical technique for comparing the semantic similarity of words or documents. In this paper, I examine the application of LSA to automated essay scoring. I compare LSA methods to earlier statistical methods for assessing essay quality, and critically review contemporary essay-scoring systems built on LSA, including the Intelligent Essay
Assessor, Summary Street, State the Essence, Apex, and Select-a-Kibitzer.
Finally, I discuss current avenues of research, including LSA's application to computer-measured readability assessment and to automatic summarization of student essays.},

title = {Application of Rasch rating scale model to analysis of job satisfaction among practicing pharmacists},
abstract = {OBJECTIVE: To demonstrate the application of Rasch analysis in the study of job satisfaction among practicing pharmacists. DESIGN: Cross-sectional survey study. SETTING: Community independent, community chain, hospital, and other pharmacies in the United States in fall 2005. PARTICIPANTS: 790 practicing pharmacists. INTERVENTION: Mailed survey based on past studies of job satisfaction. MAIN OUTCOME MEASURE: Job satisfaction as measured using the Rasch rating scale model (which considers responses on Likert scales as categorical data) and traditional estimation techniques (which assume a continuum among responses on these scales by analyzing data as interval). RESULTS: A gain in precision for the Rasch technique was observed for the constructs distributive justice, job autonomy, job ambiguity, role conflict, positive affectivity, job resources, and supervisory support. No gain in precision was found for the constructs negative affectivity and work involvement. Traditional estimates offered more precision for the constructs job repetition, promotional opportunity, and workload. CONCLUSION: Compared with traditional estimates, Rasch estimates provided more precise scores of job satisfaction on certain subscales, especially those whose mean scores were large or responses more diverse.},

title = {A hierarchical analysis of 1,710 English personality-descriptive adjectives},
abstract = {The structure of the English personality lexicon was investigated using self-ratings (N = 310) on a set of 1,710 personality-trait adjectives. The 5-factor solution resembled the Big Five structure, but included rotational variants of Agreeableness and Emotional Stability similar to those of other languages. In the 6-factor solution an additional factor, defined by terms such as unpretentious versus sly, resembled an Honesty-Humility factor observed in other languages. The 6-factor solution also produced an especially clear 5th factor, defined by Intellect, Imagination, and Unconventionality content. The hierarchical emergence of factors from 1 to 7 was explored, and the 7-factor solution yielded a Religiosity factor, adding to the diverse array of 7th factors observed in other languages.},
