title = {A comparison of self-reported puberty using the Pubertal Development Scale and the Sexual Maturation Scale in a school-based epidemiologic survey},
abstract = {PURPOSE: To examine concordance between two self-reported measures of puberty: Sexual Maturation Scale (SMS) and Pubertal Development Scale (PDS) and their acceptability to adolescents. METHODS: Participants of a school-based study in grades 5, 7 and 9 were classified into one of 5 pubertal stages using each method. RESULTS: 2864 students (age 9-16 years) participated. Agreement was moderate for males (kappa 0.42, 95% CI 0.39, 0.45) and females (kappa 0.57, 95% CI 0.53, 0.61). Concordance within one stage was excellent (females 97%, males 89%), with discrepancies due to females being classified one stage later on the PDS (26%) and males one stage earlier (32%). There were more missing data for the SMS (13%) than the PDS (4%). CONCLUSIONS: Given the level of concordance and difficulties of using the drawings in a school-based survey, we would recommend the PDS as an alternative to assess pubertal status in epidemiological studies.},

title = {Identity Statuses Based Upon Four Rather Than Two Identity Dimensions: Extending and Refining Marcia's Paradigm},
abstract = {Four identity dimensions (Commitment Making, Identification with Commitment, Exploration in Depth, and Exploration in Breadth) were used to derive identity statuses by means of cluster analysis in a sample of late adolescents. This strategy resulted in both a qualitative refinement and a quantitative extension of Marcia's (1966) model. Five clusters were retained. Four of those (the Achievement, Moratorium, Foreclosure, and Diffused Diffusion Cluster) bore a striking resemblance to Marcia's original identity statuses in terms of their definition and their associations with criterion variables. Adolescents in the fifth cluster, the Carefree Diffusion Cluster (low to moderate on both commitment dimensions and low on both exploration dimensions), scored as high as the two high Commitment Making clusters (i.e., the Achievement and Foreclosure Cluster) on several indicators of adjustment. Personality characteristics further differentiated these clusters in accordance with theory. The advantages of extending the identity status paradigm, through additional distinctions that pertain to both commitment and exploration, are discussed and practical implications are outlined.},

title = {A bridge between PLS path modeling and multi-block data analysis},
abstract = {A	situation	where	J	blocks	of	variables	X1, ..., XJ	are	observed	on the same set of individuals is considered in this paper. A factor analysis approach is applied to blocks instead of variables. The latent variables (LV's) of each block should well explain their own block and at the same time the latent variables of same order should be as highly correlated as possible (positively or in absolute value). Two path models can be used in order to obtain the first order latent variables. The first one is related to confirmatory factor analysis: each LV related to one block is connected to all the LV's related to the other blocks. Then, PLS path modeling is used with mode A and centroid scheme. Use of mode B with centroid and factorial schemes is also discussed. The second model is related to hierar- chical factor analysis. A causal model is built by relating the LV's of each block Xj to the LV of the super-block XJ+1 obtained by concatenation of X1,...,XJ. Using PLS estimation of this model with mode A and path- weighting scheme gives an adequate solution for finding the first order latent variables. The use of mode B with centroid and factorial schemes is also discussed. The higher order latent variables are found by using the same algorithms on the deflated blocks. The first approach is compared with the MAXDIFF/MAXBET Van de Geer's algorithm (1984) and the second one with the ACOM algorithm (Chessel {\&} Hanafi, 1996). Sensory data describing Loire wines are used to illustrate these methods.},

title = {Heritability of changes in brain volume over time in twin pairs discordant for schizophrenia},
abstract = {CONTEXT: Structural brain abnormalities have consistently been found in schizophrenia, with increased familial risk for the disease associated with these abnormalities. Some brain volume changes are progressive over the course of the illness. Whether these progressive brain volume changes are mediated by genetic or disease-related factors is unknown. OBJECTIVE: To investigate whether genetic and/or environmental factors are associated with progressive brain volume changes in schizophrenia. DESIGN: Longitudinal 5-year follow-up in monozygotic (MZ) and dizygotic (DZ) twin pairs discordant for schizophrenia and healthy comparison twin pairs using brain magnetic resonance imaging. SETTING: Participants were recruited from the twin pair cohort at the University Medical Center Utrecht. PARTICIPANTS: A total of 92 participants completed the study: 9 MZ and 10 DZ twin pairs discordant for schizophrenia and 14 MZ and 13 DZ healthy twin pairs. MAIN OUTCOME MEASURES: Percentage volume changes of the whole brain; cerebral gray and white matter of the frontal, temporal, parietal, and occipital lobes; cerebellum; and lateral and third ventricles over time between and within twin pairs were compared using repeated measures analysis of covariance. Structural equation modeling was applied to estimate contributions of additive genetic and common and unique environmental factors. RESULTS: Significant decreases over time in whole brain and frontal and temporal lobe volumes were found in patients with schizophrenia and their unaffected co-twins compared with control twins. Bivariate structural equation modeling using cross-trait/cross-twin correlations revealed significant additive genetic influences on the correlations between schizophrenia liability and progressive whole brain (66%; 95% confidence interval [CI], 51%-100%), frontal lobe (76%; 95% CI, 54%-100%), and temporal lobe (79%; CI, 56%-100%) volume change. CONCLUSION: The progressive brain volume loss found in patients with schizophrenia and their unaffected co-twins is at least partly attributable to genetic factors related to the illness.},

title = {Prevalence and severity of mental health-related disability and relationship to diagnosis},
abstract = {OBJECTIVE: Psychiatric disability has been defined largely from measures that focus on serious mental illness. This practice may have led to substantial underestimation of the total impact of mental disorders on community health. In this study a generic measure of mental health-related disability was used to examine disabilities attributable to various common mental disorders. METHODS: Data were drawn from the Australian National Survey of Mental Health and Wellbeing, a household survey of 10,641 adults that assessed participants for 14 DSM-IV disorders with use of the Composite International Diagnostic Interview. Screening instruments were used to identify likely cases of ICD-10 personality disorder, neurasthenia (an undifferentiated somatoform disorder), and psychosis. Mental health disability was assessed with the Medical Outcomes Study 12-item Short Form (SF-12) mental health summary scale, which was administered to all participants. RESULTS: Disability was significantly greater among participants with a current psychiatric diagnosis, and disability varied by type of disorder. Diagnosis remained a strong predictor of disability after sociodemographic factors and physical illness were controlled for. Disorders found to be independently associated with disability were depression, panic disorder, agoraphobia, social phobia, generalized anxiety disorder, alcohol dependence, and drug dependence. CONCLUSIONS: Substantial proportions of persons with mental disorders that are not usually classified as major mental disorders reported moderate and severe disability. A generic measure of mental health-related disability was able to detect variations in disability among persons with different diagnoses. Although such a measure is not as sensitive as a disorder-specific measure developed for use in psychiatric populations, it can facilitate comparison of disability across common mental disorders.},

title = {Psychological wellbeing, physical impairments and rural aging in a developing country setting},
abstract = {Background There has been very little research on wellbeing, physical impairments and disability in older people in developing countries. Method A community survey of 1147 older parents, one per household, aged sixty and over in rural Thailand. We used the Burvill scale of physical impairment, the Thai Psychological Wellbeing Scale and the brief WHO Disability Assessment Schedule. We rated received and perceived social support separately from children and from others and rated support to children. We used weighted analyses to take account of the sampling design. Results Impairments due to arthritis, pain, paralysis, vision, stomach problems or breathing were all associated with lower wellbeing. After adjusting for disability, only impairment due to paralysis was independently associated with lowered wellbeing. The effect of having two or more impairments compared to none was associated with lowered wellbeing after adjusting for demographic factors and social support (adjusted difference -2.37 on the well-being scale with SD=7.9, p<0.001) but after adjusting for disability the coefficient fell and was non-significant. The parsimonious model for wellbeing included age, wealth, social support, disability and impairment due to paralysis (the effect of paralysis was -2.97, p=0.001). In this Thai setting, received support from children and from others and perceived good support from and to children were all independently associated with greater wellbeing whereas actual support to children was associated with lower wellbeing. Low received support from children interacted with paralysis in being especially associated with low wellbeing. Conclusions In this Thai setting, as found in western settings, most of the association between physical impairments and lower wellbeing is explained by disability. Disability is potentially mediating the association between impairment and low wellbeing. Received support may buffer the impact of some impairments on wellbeing in this setting. Giving actual support to children is associated with less wellbeing unless the support being given to children is perceived as good, perhaps reflecting parental obligation to support adult children in need. Improving community disability services for older people and optimizing received social support will be vital in rural areas in developing countries.},

abstract = {Two-by-two tables commonly arise in comparative trials and cross-sectional studies. In medical studies, two-by-two tables may have a small sample size due to the rarity of a condition, or to limited resources. Current recommendations on the appropriate statistical test mostly specify the chi-squared test for tables where the minimum expected number is at least 5 (following Fisher and Cochran), and otherwise the Fisher-Irwin test; but there is disagreement on which versions of the chi-squared and Fisher-Irwin tests should be used. A further uncertainty is that, according to Cochran, the number 5 was chosen arbitrarily. Computer-intensive techniques were used in this study to compare seven two-sided tests of two-by-two tables in terms of their Type I errors. The tests were K. Pearson's and Yates's chi-squared tests and the 'N-1' chi-squared test (first proposed by E. Pearson), together with four versions of the Fisher-Irwin test (including two mid-P versions). The optimum test policy was found to be analysis by the 'N-1' chi-squared test when the minimum expected number is at least 1, and otherwise, by the Fisher-Irwin test by Irwin's rule (taking the total probability of tables in either tail that are as likely as, or less likely than the one observed). This policy was found to have increased power compared to Cochran's recommendations.},

title = {Sparse estimation of large covariance matrices via a nested lasso penalty},
abstract = {The paper proposes a new covariance estimator for large covari- ance matrices when the variables have a natural ordering. Using the Cholesky decomposition of the inverse, we impose a banded structure on the Cholesky factor, and select the bandwidth adaptively for each row of the Cholesky factor, using a novel penalty we call nested Lasso. This structure has more flexibility than regular banding, but, unlike regular Lasso applied to the entries of the Cholesky factor, results in a sparse estimator for the inverse of the covariance matrix. An it- erative algorithm for solving the optimization problem is developed. The estimator is compared to a number of other covariance estima- tors and is shown to do best, both in simulations and on a real data example. Simulations show that the margin by which the estimator outperforms its competitors tends to increase with dimension.},

Using a community sample .N D 956/ of male HIV positive patients, we tested a mediation model in which the relationship between Symptoms and QOL is partially mediated by Disability. Common and unique ideas from 3 approaches to examining moderation of effects in mediational models (Edwards {\&} Lambert, 2007; MacKinnon, 2008; Preacher, Rucker, {\&} Hayes, 2007) were used to test whether (a) the direct relationship of Symptoms to QOL and (b) the relationship of Disability to QOL are moderated by age. In the mediation model, both the direct and the indirect (mediated) effects were significant. The direct relationship of Symptoms to QOL was significantly moderated by age, but the relationship of Disability to QOL was not. High Symptoms were associated with lower QOL at all ages, but this relationship became stronger at older ages. We compare the 3 approaches and consider their advantages over traditional approaches to combining mediation and moderation.},

title = {Antepartum and postpartum exposure to maternal depression: different effects on different adolescent outcomes},
abstract = {BACKGROUND: Postpartum depression (PPD) is considered a major public health problem that conveys risk to mothers and offspring. Yet PPD typically occurs in the context of a lifelong episodic illness, and its putative effects might derive from the child's exposure to other episodes, in pregnancy or later childhood. The aim of the study is to test two hypotheses: (1) that the effects of PPD on adolescent outcomes are partly explained by antepartum depression (APD) and (2) that the effects of APD and PPD are both explained by later exposure to the mother's depression. METHOD: A random sample of 178 antenatal patients was drawn from two general medical practices in South London; 171 gave birth to live infants, and 150 (88%) were assessed at 3 months post partum, with 121 of their offspring (81%) assessed for emotional disorders (ED), disruptive behaviour disorders (DBD) and IQ, at 11 and 16 years of age. RESULTS: When APD and subsequent episodes of depression were taken into account, PPD had a significant effect on adolescent IQ, especially for boys, but did not predict psychopathology. ED and DBD in adolescence were predicted by the extent of exposure to maternal depression after 3 months post partum; a significant effect of APD on ED in girls was accounted for by later exposure to the mother's illness. Mothers' symptoms of anxiety, smoking and alcohol use in pregnancy did not predict adolescent outcomes, once maternal depression was taken into account. CONCLUSIONS: Some effects attributed to mothers' mental health problems in pregnancy or post partum may be mediated by cumulative exposure to maternal illness, probably reflecting genetic influence and gene-environment correlation. However, PPD has a direct effect on cognition. Clinicians should endeavour to identify women with depression in pregnancy (31% of this sample) and help them to manage their lifelong illness.},

title = {Psychometric analysis of the self-harm inventory using Rasch modelling},
abstract = {BACKGROUND: Deliberate Self-Harm (DSH) is the intentional destruction of healthy body tissue without suicidal intent. DSH behaviours in non-clinical populations vary, and instruments containing a range of behaviours may be more informative than ones with restricted content. The Self-Harm Inventory (SHI) is a widely used measure of DSH in clinical populations (mental and physical health) and covers a broad range of behaviours (self-injury, risk taking and self-defeating acts). The test authors recommend the SHI to screen for Borderline Personality Disorder (BPD) using a cut-off score of five or more. The aim of this study was to investigate the psychometric characteristics of the SHI in non-clinical samples. METHODS: The SHI was administered to a sample of 423 non-clinical participants (university students, age range 17 to 30). External validation was informed by the administration of the Depression Anxiety Stress Scales 21 (DASS-21) to a sub-sample (n = 221). Rasch analysis of the SHI was conducted to provide a stringent test of unidimensionality and to identify the DSH behaviours most likely to be endorsed at each total score. RESULTS: The SHI showed adequate fit to the Rasch model and no modifications were required following checks of local response dependency, differential item functioning and unidimensionality. The scale identified gender and age differences in scores, with females and older participants reporting higher levels of DSH. SHI scores and DASS-21 scores were related. CONCLUSION: The recommended cut-off point of five is likely to comprise mild forms of DSH and may not be indicative of psychopathology in a non-clinical population. Rather it may be more indicative of developmentally related risk taking behaviours while a higher cut-off point may be more suggestive of psychopathology as indicated by higher levels of depression, stress and anxiety.},

perceived self-esteem stability (within-person variability) by using a behavioral genetics approach. We tested whether the same or independent genetic and environmental influences impact on level and stability. Adolescent twin siblings (n = 183 pairs) completed level and stability scales at two time points. Heritability for both was substantial. The remaining variance in each was attributable to non-shared environmental influences. Shared environmental influences were not significant. Level and stability of self-esteem shared common antecedents via genetic and non-shared environmental influences. Nonetheless, stability was influenced by substantial unique genetic and non-shared environmental influences. The results validate the notion that level and stability are partially autonomous components of self-esteem.},

However, research examining attachment and psychological health in adolescents frequently fails to distinguish between the different dimensions of psychological health and their differential relationship to attachment and key personality and life event variables. This cross-sectional study of 404 adolescents examined the role of attachment, neuroticism, extraversion, and positive and negative life events in psychological well-being and distress. Quality of attachment to parents, but not peers, predicted increased well-being and decreased distress independent of neuroticism, extraversion, and life event variables. It is concluded that while parental attachment is implicated in psychological health, the role and status of measures of quality of peer relationships as attachment is unclear.},

title = {The CHRNA5/A3/B4 gene cluster variability as an important determinant of early alcohol and tobacco initiation in young adults},
abstract = {BACKGROUND: One potential site of convergence of the nicotine and alcohol actions is the family of the neuronal nicotinic acetylcholine receptors. Our study examines the genetic association between variations in the genomic region containing the CHRNA5, A3, and B4 gene cluster (A5A3B4) and several phenotypes of alcohol and tobacco use in an ethnically diverse young adult sample. Significant results were then replicated in a separate adult population-representative sample. METHODS: In a selected sample, nine single nucleotide polymorphisms (SNPs) were tested for association with various nicotine and alcohol phenotypes, including age of initiation and measures of frequency, quantity, and subjective responses to the substances. Analysis was conducted with the statistical genetics program WHAP in the full sample (1075 subjects) including ethnicities as covariates and within each ethnic group sub-sample. Replication of the significant results in a separate population-based sample was carried out with the PBAT statistical genetics program. RESULTS: Two linked SNPs (rs8023462 and rs1948) located in a conserved region of the A5A3B4 gene cluster significantly predicted early age of initiation for tobacco with a hazard ratio (HR) of 1.35 (95% confidence interval [CI]1.08-1.70) for the TT genotype of rs8023462 and a HR of 1.29 (95% CI 1.01-1.63) for the CC genotype of rs1948. These findings were then replicated in a separate population-representative sample, showing rs1948 and rs8023462 to be associated with age of initiation for both tobacco and alcohol use (p < .01 and p < .001). CONCLUSIONS: Variations in A5A3B4 genes might influence behaviors that promote early age of experimentation with drugs.},

In contrast to several previous estimators, the new estimator is well behaved and applies to any number of alleles per locus and any allele frequency distribution. The estimates for two- and four-gene coefficients of relatedness from the new estimator are unbiased irrespective of the sample size and have sampling variances decreasing consistently with an increasing number of alleles per locus to the minimum asymptotic values determined by the variation in identity-by-descent among loci per se, regardless of the actual relationship. The new estimator is also robust for small sample sizes and for unknown relatives being included in samples for estimating allele frequencies. Compared to previous estimators, the new one is generally advantageous, especially for highly polymorphic loci and/or small sample sizes.},

In cases where path analysis is used in prac- tice, it is often possible to use parcels as indicators of a latent variable. The pur- pose of the current study was to compare latent variable models in which parcels were used as indicators of the latent variables, path analysis models of the aggre- gated variables, and models in which reliability estimates were used to correct for measurement error in path analysis models. Results showed that point estimates of path coefficients were smallest for the path analysis models and largest for the la- tent variable models.

title = {Functional brain mapping of extraversion and neuroticism: learning from individual differences in emotion processing},
abstract = {This review outlines how functional brain imaging, using an individual-differences approach in the processing of emotional stimuli, has begun to reveal the neural basis of extraversion (E) and neuroticism (N), two traits that are linked to both emotion and health. Studies using functional magnetic resonance imaging have shown that individual differences in participants' E and N scores are correlated with individual differences in brain activation in specific brain regions that are engaged during cognitive-affective tasks. Imaging studies using genotyped participants have begun to address the molecular mechanisms that may underlie these individual differences. The multidisciplinary integration of brain imaging and molecular genetic methods offers an exciting and novel approach for investigators who seek to uncover the biological mechanisms by which personality and health are interrelated.},

title = {A combined strategy for quantitative trait loci detection by genome-wide association},
abstract = {BACKGROUND: We applied a range of genome-wide association (GWA) methods to map quantitative trait loci (QTL) in the simulated dataset provided by the 12th QTLMAS workshop in order to derive an effective strategy. RESULTS: A variance component linkage analysis revealed QTLs but with low resolution. Three single-marker based GWA methods were then applied: Transmission Disequilibrium Test and single marker regression, fitting an additive model or a genotype model, on phenotypes pre-corrected for pedigree and fixed effects. These methods detected QTL positions with high concordance to each other and with greater refinement of the linkage signals. Further multiple-marker and haplotype analyses confirmed the results with higher significance. Two-locus interaction analysis detected two epistatic pairs of markers that were not significant by marginal effects. Overall, using stringent Bonferroni thresholds we identified 9 additive QTL and 2 epistatic interactions, which together explained about 12.3% of the corrected phenotypic variance. CONCLUSION: The combination of methods that are robust against population stratification, like QTDT, with flexible linear models that take account of the family structure provided consistent results. Extensive simulations are still required to determine appropriate thresholds for more advanced model including epistasis.},

abstract = {INTRODUCTION: The new view of cognitive neuropsychology that considers not just case studies of rare severe disorders but also common disorders, as well as normal variation and quantitative traits, is more amenable to recent advances in molecular genetics, such as genome-wide association studies, and advances in quantitative genetics, such as multivariate genetic analysis. A surprising finding emerging from multivariate quantitative genetic studies across diverse learning abilities is that most genetic influences are shared: they are "generalist", rather than "specialist". METHODS: We exploited widespread access to inexpensive and fast Internet connections in the United Kingdom to assess over 5000 pairs of 12-year-old twins from the Twins Early Development Study (TEDS) on four distinct batteries: reading, mathematics, general cognitive ability (g) and, for the first time, language. RESULTS: Genetic correlations remain high among all of the measured abilities, with language as highly correlated genetically with g as reading and mathematics. CONCLUSIONS: Despite developmental upheaval, generalist genes remain important into early adolescence, suggesting optimal strategies for molecular genetic studies seeking to identify the genes of small effect that influence learning abilities and disabilities.},

title = {Comparing three short questionnaires to detect psychosocial dysfunction among primary school children: a randomized method},
abstract = {BACKGROUND: Good questionnaires are essential to support the early identification of children with psychosocial dysfunction in community based settings. Our aim was to assess which of three short questionnaires was most suitable for this identification among school-aged children METHODS: A community-based sample of 2,066 parents of children aged 7-12 years (85% of those eligible) filled out the Child Behavior Checklist (CBCL) and - randomly determined - one of three questionnaires to be compared: the Strengths and Difficulties Questionnaire with Impact Supplement (SDQ), the Pediatric Symptom Checklist (PSC) and the PSYBOBA, a Dutch-origin questionnaire. Preventive Child Healthcare professionals assessed children's psychosocial functioning during routine health examinations. We assessed the scale structure (by means of Structural Equation Modelling), validity (correlation coefficients, sensitivity and specificity) and usability (ratings by parents and professionals) of each questionnaire and the degree to which they could improve the identification based only on clinical assessment (logistic regression). RESULTS: For the three questionnaires, Cronbach's alphas varied between 0.80 and 0.89. Sensitivities for a clinical CBCL at a cut off point with specificity = 0.90 varied between 0.78 and 0.86 for the three questionnaires. Areas under the Receiver Operating Curve, using the CBCL as criterion, varied between 0.93 and 0.96. No differences were statistically significant. All three questionnaires added information to the clinical assessment. Odds ratios (95% confidence intervals) for added information were PSC: 29.3 (14.4-59.8), SDQ: 55.0 (23.1-131.2) and PSYBOBA: 68.5 (28.3-165.6). Parents preferred the SDQ and PSYBOBA. Preventive Child Health Care professionals preferred the SDQ. CONCLUSIONS: This randomized comparison of three questionnaires shows that each of the three questionnaires can improve the detection of psychosocial dysfunction among children substantially.},

abstract = {OBJECTIVE: To demonstrate the value of item response theory (IRT) and differential item functioning (DIF) methods in examining a health-related quality-of-life measure in children and adolescents. STUDY DESIGN AND SETTING: This illustration uses data from 5,429 children using the four subscales of the PedsQL 4.0 Generic Core Scales. The IRT model-based likelihood ratio test was used to detect and evaluate DIF between healthy children and children with a chronic condition. RESULTS: DIF was detected for a majority of items but canceled out at the total test score level due to opposing directions of DIF. Post hoc analysis indicated that this pattern of results may be due to multidimensionality. We discuss issues in detecting and handling DIF. CONCLUSION: This article describes how to perform DIF analyses in validating a questionnaire to ensure that scores have equivalent meaning across subgroups. It offers insight into ways information gained through the analysis can be used to evaluate an existing scale.},

RESULTS: We present SNPExpress, a software tool to accurately analyze Affymetrix and Illumina SNP genotype calls, copy numbers, polymorphic copy number variations (CNVs) and Affymetrix gene expression in a combinatorial and efficient way. In addition, SNPExpress allows concurrent interpretation of these items with Hidden-Markov Model (HMM) inferred Loss-of-Heterozygosity (LOH)- and copy number regions. CONCLUSION: The combined analyses with the easily accessible software tool SNPExpress will not only facilitate the recognition of recurrent genetic lesions, but also the identification of critical pathogenic genes.},

title = {Logic Regression},
abstract = {Logic regression is an adaptive regression methodology that attempts to construct predictors as Boolean combinations of binary covariates. In many regression problems a model is developed that relates the main effects (the predictors or transformations thereof) to the response, while interactions are usually kept simple (two- to three-way interactions at most). Often, especially when all predictors are binary, the interaction between many predictors may be what causes the differences in response. This issue arises, for example, in the analysis of SNP microarray data or in some data mining problems. In the proposed methodology, given a set of binary predictors we create new predictors such as ``X1, X2, X3, and X4 are true,'' or ``X5 or X6 but not X7 are true.'' In more specific terms: we try to fit regression models of the form g(E[Y]) = b0 + b1 L1 + · · · + bn Ln , where Lj is any Boolean expression of the predictors. The Lj and bj are estimated simultaneously using a simulated annealing algorithm. This article discusses how to fit logic regression models, how to carry out model selection for these models, and gives some examples.},

We contrast the biometric-factors covariance structure approach used by Loehlin and Vandenberg (1968), Martin and Eaves (1977), and others with the psychometric-factors approach used by McArdle et al. (1980) and others. We use the multivariate primary mental abilities data on monozygotic (MZ) and dizygotic (DZ) twins from Loehlin and Vandenberg (1968) to detail fundamental differences in model specification and results. We extend both multivariate biometric approaches using exploratory and confirmatory multiple-factor models. These comparisons show that each alternative multivariate methodology has useful features for empirical applications.},

System1 relies either on pragmatic implica- tures or on the retrieval of information from semantic memory; System2 operates first through inhibition of System1, then (but not always) through activation of analytical processes. It follows that reasoners will fall into one of four groups of increasing reasoning ability, each group being uniquely characterized by (a) the modal pattern of individual answers to blocks of affirming the consequent, denying the antecedent, and modus tollens syllogisms featuring the same conditional; and (b) the average rate of determinate answers to , , and . This account receives indirect support from the extant literature, and direct support from a mixed Rasch model of responses given to 18 syllogisms by 486 adult reasoners.},

Personality disorders appeared to be more important statistical predictors of quality of life than sociodemographic variables, somatic health, and axis I disorder. Those with avoidant, schizotypal, paranoid, schizoid, and borderline PDs had the strongest and broadest reduction in quality of life, whereas those with histrionic, obsessive-compulsive, passive-aggressive, and sadistic PDs did not show any reduction. A number of specific relationships occurred. Furthermore, the more PDs that existed and the more personality criteria fulfilled, the poorer the quality of life, pointing to the importance of comorbidity and continuity.},

abstract = {Glycerol kinase deficiency (GKD) is an X-linked inborn error of metabolism with metabolic and neurological crises. Liver shows the highest level of glycerol kinase (GK) activity in humans and mice. Absence of genotype-phenotype correlations in patients with GKD indicates the involvement of modifier genes, including other network partners. To understand the molecular pathogenesis of GKD, we performed microarray analysis on liver mRNA from neonatal glycerol kinase (Gyk) knockout (KO) and wild-type (WT) mice. Unsupervised learning revealed that the overall gene expression profile of the KO mice was different from that of WT. Real-time PCR confirmed the differences for selected genes. Functional gene enrichment analysis was used to find 56 increased and 37 decreased gene functional categories. PathwayAssist analysis identified changes in gene expression levels of genes involved in organic acid metabolism indicating that GK was part of the same metabolic network which correlates well with the patients with GKD having metabolic acidemia during their episodic crises. Network component analysis (NCA) showed that transcription factors sterol regulatory element-binding protein (SREBP)-1c, carbohydrate response element-binding protein (ChREBP), hepatocyte nuclear factor-4 alpha (HNF-4alpha) and peroxisome proliferative-activated receptor-alpha (PPARalpha) had increased activity in the Gyk KO mice compared with WT mice, whereas SREBP-2 was less active in the Gyk KO mice. These studies show that Gyk deletion causes alterations in expression of genes in several regulatory networks and is the first time NCA has been used to expand on microarray data from a mouse KO model of a human disease.},

The degree of het- erogeneity among appearance and performance enhancing drug (APED) users is unknown and an empirically derived framework for studying BID is necessary. APED users (N = 1000) were recruited via the Internet and they completed a comprehensive online assessment APED use patterns, motivations, consequences, and BID. Data were evaluated using latent trait, latent class, and factor mixture models. Model results were validated using a range of covariates including cycle characteristics, age, APED his- tory, and APED risk. A 1-Factor, 4-Class model provided the best fit to the data with Class 1 scoring the highest on all measures of BID and Class 4 the lowest on all measures. Class 2 differed in their pref- erence for being lean over muscular and Class 3 preferred adding mass and size. Each class was associated with unique risks, APED history, and training identity. Not all APED users suffer from significant BID and there are unique profiles for those with elevated BID. Future research on male BID should account for this structure in order to better define relevant diagnostic categories and evaluate the clinical significance of BID.},

title = {Neural responses to monetary incentives in major depression},
abstract = {BACKGROUND: Reduced responsiveness to positive incentives is a central feature of Major Depressive Disorder (MDD). In the present study, we compared neural correlates of monetary incentive processing in unmedicated depressed participants and never-depressed control subjects. METHODS: Fourteen currently depressed and 12 never-depressed participants underwent functional magnetic resonance imaging while participating in a monetary incentive delay task. During the task, participants were cued to anticipate and respond to a rapidly presented target to gain or avoid losing varying amounts of money. RESULTS: Depressed and never-depressed participants did not differ in nucleus accumbens (NAcc) activation or in affective or behavioral responses during gain anticipation. Depressed participants did, however, exhibit increasing anterior cingulate activation during anticipation of increasing gains, whereas never-depressed participants showed increasing anterior cingulate activation during anticipation of increasing loss. Depressed participants also showed reduced discrimination of gain versus nongain outcomes. CONCLUSIONS: The present findings indicate that although unmedicated depressed individuals have the capacity to experience positive arousal and recruit NAcc activation during gain anticipation, they also exhibit increased anterior cingulate cortex activation, suggestive of increased conflict during anticipation of gains, in addition to showing reduced discrimination of gain versus nongain outcomes.},

abstract = {OBJECTIVE: This study represented the first attempt to directly evaluate Fairburn et al's (1986) cognitive-behavioral model of bulimia nervosa--the model on which the most widely used treatment for bulimia nervosa is based. METHOD: The major predictions of the model were tested using structural equation modeling. Data were collected from the responses of 526 subjects to a number of self-report measures. RESULTS: The factors of self-esteem, overconcern with weight and shape, and dietary restraint accounted for a large proportion of the variance in binge eating and purging. The key pathway in the model was the link between overconcern with weight and shape and the adoption of purgative behaviors, which then fed into a vicious cycle of binge eating and purging. Contrary to Fairburn's hypothesis, high levels of dietary restraint did not predict increased binge eating. DISCUSSION: The results suggest that the components of Fairburn's model may operate to maintain the bulimic cycle in a slightly different way to that originally proposed.},

title = {Variance decomposition of MRI-based covariance maps using genetically informative samples and structural equation modeling},
abstract = {The role of genetics in driving intracortical relationships is an important question that has rarely been studied in humans. In particular, there are no extant high-resolution imaging studies on genetic covariance. In this article, we describe a novel method that combines classical quantitative genetic methodologies for variance decomposition with recently developed semi-multivariate algorithms for high-resolution measurement of phenotypic covariance. Using these tools, we produced correlational maps of genetic and environmental (i.e. nongenetic) relationships between several regions of interest and the cortical surface in a large pediatric sample of 600 twins, siblings, and singletons. These analyses demonstrated high, fairly uniform, statistically significant genetic correlations between the entire cortex and global mean cortical thickness. In agreement with prior reports on phenotypic covariance using similar methods, we found that mean cortical thickness was most strongly correlated with association cortices. However, the present study suggests that genetics plays a large role in global brain patterning of cortical thickness in this manner. Further, using specific gyri with known high heritabilities as seed regions, we found a consistent pattern of high bilateral genetic correlations between structural homologues, with environmental correlations more restricted to the same hemisphere as the seed region, suggesting that interhemispheric covariance is largely genetically mediated. These findings are consistent with the limited existing knowledge on the genetics of cortical variability as well as our prior multivariate studies on cortical gyri.},

abstract = {Despite the increasing realization that health-related quality of life (HRQOL) is an important outcome in chronic HBV infection, there are no validated, disease-targeted instruments currently available. We sought to develop and validate the first disease-targeted HRQOL instrument in noncirrhotic HBV: the Hepatitis B Quality of Life instrument, version 1.0 (HBQOL v1.0). We established content validity for the HBQOL v1.0 by conducting a systematic literature review, an expert focus group, and cognitive interviews with HBV patients. We administered the resultant questionnaire to 138 HBV patients. We used factor analysis to test hypotheses regarding HRQOL domains and measured construct validity by comparing HBQOL v1.0 scores across several anchors, including viral response to treatment, SF-36 scores, and global health. Finally, we measured test-retest and internal consistency reliability. Content validation revealed that HBV affects multiple aspects of psychological, social, and physical health. The resultant questionnaire summarized this HRQOL impact with 31 items across six subscales: psychological well-being, anticipation anxiety, vitality, disease stigma, vulnerability, and transmissibility. Internal consistency and test-retest reliability were excellent. The HBQOL v1.0 discriminated between viral responders versus nonresponders and correlated highly with SF-36 scores and global health. CONCLUSION: Patients with chronic HBV infection attribute a wide range of negative psychological, social, and physical symptoms to their condition, even in the absence of cirrhosis or cancer. The HBQOL v1.0 is a valid and reliable measure that captures this HRQOL decrement. This instrument may be useful in everyday clinical practice and in future clinical trials.},

title = {Autism and other pervasive developmental disorders: exploring the dimensional view},
abstract = {OBJECTIVE: To examine empirical data on children with autistic disorder (AD), Asperger's disorder, and pervasive developmental disorder not otherwise specified (PDD-NOS) for continuities or distinguishing features between disorder and to see to what extent the Diagnostic and Statistical Manual of Mental Disorder (DSM-IV) diagnostic criteria-reflect observed data. METHOD: Studies were identified in 4 ways. 1)A Medline search from 1976 to the present of articles with the key words autism, pervasive developmental disorder, autistic spectrum disorder, and Asperger; of these articles, those with mesh headings or textwords "cluster," which identified cluster analyses deriving pervasive developmental disorder (PDD) subtypes, were retained 2) The Journal of Autistic and Developmental Disorder from 1990 to the present was hand-searched to identify other empirically derived studies on diagnosis, prevalence, classification, and validity of PDD subtypes. 3) Key review articles were searched for their references. 4) The references of all identified articles were searched. RESULTS: Eight cluster studies were retained for their relevance to diagnostic issues, as were 7 empirically derived studies delineating clinic characteristics of children will AD, Asperger's syndrome, or PDD-NOS. Data suggests that children with PDD may fit into 1 of 2 overlapping groups, including a lower-functioning group with greater developmental compromise, social aloofness, and a greater number of autistic symptoms and a higher-functioning group with higher IQ, fewer autistic symptoms, and more prosocial behavior. The PDD subtype resemble each other and can be seen as existing o a continuum, differing only by degree of impairment. CONCLUSION: Children exhibiting the triad of autistic impairments can be seen as suffering from disorders on a PDD continuum. While the DSM-IV does identify a lower-functioning autistic group (AD), the higher-functioning group is less well served. Asperger's disorder as defined in the DSM-IV is not clearly distinguishable from AD and PDD-NOS, and the PDD-NOS subcategory is not operationalized. Further research is required to elaborate criteria for the higher-functioning PDD group, and measures related to etiology, outcome, and treatment response may help determine which diagnostic criteria can meaningfully separate one disorder from another.},

Patients meeting the American Psychiatric Association's Diagnostic and Statistical Manual of mental disorders (1994) criteria for panic disorder (N = 71) completed 12 sessions of cognitive-behavioral treatment and were assessed at posttreatment and 6-month follow-up. Medical comorbidity and perceived health were both found to be related to end-state functioning. Medical comorbidity did not uniquely predict outcome beyond its shared variance with perceived health. At posttreatment, 71% of patients who perceived their physical health as good met recovery criteria compared with only 35% of those who perceived their health as poor. At follow-up, 67% of those who perceived their physical health as good met composite recovery criteria compared with only 33% of those with perceived poor health. These findings offer preliminary support for the impact of physical health, both actual and perceived, on treatment outcome of patients with panic disorder.},

abstract = {In addiction, loss of prefrontal inhibitory control is believed to contribute to impulsivity. To improve cognitive therapy approaches, it is important to determine whether cognitive control strategies can generally influence reward processing at the neural level. We investigated the effects of one such strategy--namely, reappraisal (distancing from feelings)--on neural reward processing in 16 healthy subjects by utilizing event-related functional magnetic resonance imaging (fMRI). In a monetary incentive delay task, expected reward value (expecting to win 0.50 euro vs. 0.10 euro) and outcome valence (win vs. omission) were varied. An attenuation of expected value and a modulation of prediction error (PE) coding caused by distancing were found in right vs. left ventral striatum (VST) in the expectation vs. outcome period, respectively. Distancing from reward feelings recruited a right hemispheric fronto-parietal network. Moreover, self-reported reappraisal success (decrease of feelings by distancing) showed a trend toward positive correlation with activation in the rostral cingulate zone and the lateral orbitofrontal cortex, both part of the regulation network. Our results expand upon recent findings by showing that cognitive control over reward processing impacts not only the expectation period but also the reward signals in the outcome period. Moreover, increased recruitment of prefrontal reflective subsystems might enhance deliberate control over both reward processing and hedonic experience.},

abstract = {It has been increasing rapidly interest in understanding genetic effects on brain structure and function in recent years. In this study, we examined the genetic and environmental influences on the variation in cortical thickness and specific tissue volumes in a large cohort of 8-year-old healthy twins. The present study can provide a better estimation of the genetic and environmental effects by virtue of the homogeneously aged pediatric twin pairs with a similar growing environment. We found that common environmental factors contributed significantly to the variations of the right lateral ventricle (36%) and corpus callosum (36%) volumes while genetic factors accounted for most of the phenotypic variance in other brain tissue volumes. In the case of cortical thickness, several regions in the left hemisphere showed statistically significant additive genetic factors, including the middle and inferior frontal gyri, lateral fronto-orbital and occipitotemporal gyri, pars opercularis, planum temporale, precentral and parahippocampal gyri and the medial region of the primary somatosensory cortex. Relatively high common environmental influence (>50%) was observed in the right anterior cingulate cortex and insula. Our findings indicate that the genetic and common environmental influences on individual human brain structural differences are lateralized, with the language-dominant left cerebral cortex under stronger genetic control than the right.},

title = {Computerized adaptive measurement of depression: a simulation study},
abstract = {BACKGROUND: Efficient, accurate instruments for measuring depression are increasingly important in clinical practice. We developed a computerized adaptive version of the Beck Depression Inventory (BDI). We examined its efficiency and its usefulness in identifying Major Depressive Episodes (MDE) and in measuring depression severity. METHODS: Subjects were 744 participants in research studies in which each subject completed both the BDI and the SCID. In addition, 285 patients completed the Hamilton Depression Rating Scale. RESULTS: The adaptive BDI had an AUC as an indicator of a SCID diagnosis of MDE of 88%, equivalent to the full BDI. The adaptive BDI asked fewer questions than the full BDI (5.6 versus 21 items). The adaptive latent depression score correlated r =.92 with the BDI total score and the latent depression score correlated more highly with the Hamilton (r =.74) than the BDI total score did (r =.70). CONCLUSIONS: Adaptive testing for depression may provide greatly increased efficiency without loss of accuracy in identifying MDE or in measuring depression severity.},

title = {Is depression associated with health risk-related behaviour clusters in adults?},
abstract = {BACKGROUND: Depressive disorders have been linked to health risk-related behaviours (HRBs) considered separately. Our objective was to study whether depression is associated with the co-occurrence of HRBs in adults. METHODS: A sample of 17 355 subjects aged > or =18 years, derived from the 2002-03 cross-sectional Decennial Health Survey; probable depression was assessed with the CES-D scale. A cluster analysis of various HRBs (tobacco use, alcohol use, binge drinking, physical inactivity, certain eating habits) was used to study their co-occurrence. Multiple regressions adjusted on demographic and socio-economic characteristics, Body Mass Index and chronic illnesses were performed to study associations between probable depression and the HRBs clusters obtained. RESULTS: Five clusters were observed evidencing a gradient
