Abstract
OBJECTIVE Depression is conceptualized as both a risk factor for and a consequence of elder abuse; however, current research is equivocal. This study examined associations between elder abuse and dimensions of depressive symptoms in older adults. METHOD Participants were 10,419 older adults enrolled in theChicago Health and Aging Project (CHAP), a population-based study of older adults. Regression was used to determine the relationships between depressive symptoms, depression dimensions, and abuse variables. RESULTS Depressive symptoms were consistently associated with elder abuse. Participants in the highest tertile of depressive symptoms were twice as likely to have confirmed abuse with a perpetrator (odds ratio = 2.07, 95% confidence interval = [1.21, 3.52], p = .008). Elder abuse subtypes and depression dimensions were differentially associated. DISCUSSION These findings highlight the importance of routine depression screening in older adults as a component of abuse prevention and intervention. They also provide profiles of depressive symptoms that may more accurately characterize risk for specific types of abuse.

Abstract
The aim of this study was to investigate the relationship of attention deficit/hyperactivity symptoms (ADHS) with severity of Internet addiction risk (SIAR), while controlling the effects of variables such as depression, anxiety, anger, sensation seeking and lack of assertiveness among university students. Cross-sectional online self-report survey was conducted in two universities among a representative sample of 582 Turkish university students. The students were assessed through the Addiction Profile Index Internet Addiction Form Screening Version (BAPINT-SV), the Psychological Screening Test for Adolescents (PSTA) and the Adult Attention deficit/hyperactivity disorder Self-Report Scale (ASRS). The participants were classified into the two groups as those with high risk of Internet addiction (HRIA) (11%) and those with low risk of Internet addiction (IA) (89%). The mean age was lower in the group with HRIA, whereas depression, anxiety, sensation seeking, anger, lack of assertiveness and ADHS scores were higher in this group. Lastly, a hierarchical regression analysis suggested that severity of sensation seeking and ADHS, particularly attention deficiency, predicted SIAR. The severity of sensation seeking and ADHS, particularly attention deficit symptoms, are important for SIAR. Awareness of sensation seeking among those with high ADHS may be important in prevention and management of IA among university students.

Abstract
BACKGROUND Twin studies of internalizing disorders suggest that their high co-morbidity is partially explained by shared genetic risk. Few studies have investigated pleiotropic effects of well-validated candidate genes across phenotypes. METHOD Subjects were 928 Caucasian patients who presented to an out-patient clinic specializing in the assessment and treatment of anxiety and mood disorders. We constructed latent dimensional phenotypes across the internalizing spectrum (neuroticism, extraversion, depression, generalized anxiety, panic/agoraphobia, social phobia, post-traumatic stress, and obsessions-compulsions) by combining diagnostic criteria with other clinical indicators. We selected multiple variants in four evidence-based candidate genes (SLC6A4, COMT, GAD1, RGS2) with previously reported effects on several of these phenotypes. We conducted genetic association testing of their direct and indirect effects as well as gene × stress interactions (G × E). RESULTS We detected 19 nominally significant main effect associations for the 10 polymorphisms tested among the eight phenotypes (24%). These were generally phenotype non-specific, showing pleiotropic effects across multiple domains. The majority of observed sharing was between depression, panic disorder, and post-traumatic stress disorder. Some of these were best explained by mediational models in which genes increase liability for disorders indirectly via their effects on temperament. Limited G × E effects were detected between variants in SLC6A4 and both panic/agoraphobia and post-traumatic stress. CONCLUSIONS Examining just a few candidate genes for their potential roles in internalizing phenotypes, we found moderate support for the shared effects of several polymorphisms. These findings highlight the richness and complexity by which genes potentially contribute to psychopathology via pleiotropy, moderation by stress, and mediation by temperament.

Abstract
In a six-wave longitudinal study with two cohorts (660 adolescents and 630 young adults), this study investigated the longitudinal stability of the Beck Depression Inventory II (BDI-II) using the Trait-State-Occasion (TSO) model. The results revealed that the full TSO model was the best fitting representation of the depression measured by the BDI-II for both cohorts. It was found that the trait components explained more than 50% of the state variance of the BDI-II scores in both cohorts, and the occasion-specific factor explained about 7% to 12% of variances. The occasion-specific variance was more stable (occasion stability) and somewhat higher in the younger cohort. Implications regarding the longitudinal stability of the BDI-II measure are discussed.

Abstract
Low positive emotion distinguishes depression from most types of anxiety. Formative work in this area employed the Anhedonic Depression scale from the Mood and Anxiety Symptom Questionnaire (MASQ-AD), and the MASQ-AD has since become a popular measure of positive emotion, often used independently of the full MASQ. However, two key assumptions about the MASQ-AD-that it should be represented by a total scale score, and that it measures time-variant experiences-have not been adequately tested. The present study factor analyzed MASQ-AD data collected annually over 3 years (n = 618, mean age = 17 years at baseline), and then decomposed its stable and unstable components. The results suggested the data were best represented by a hierarchical structure, and that less than one quarter of the variance in the general factor fluctuated over time. The implications for interpreting past findings from the MASQ-AD, and for conducting future research with the scale, are discussed.

Abstract
Although the emotional disorders (EDs) have achieved favorable reliability in the Diagnostic and Statistical Manual of Mental Disorders (DSM), accumulating evidence continues to underscore limitations in ED diagnostic validity. In particular, taxometric, comorbidity, and other descriptive psychopathology studies of transdiagnostic phenotypes studies suggest that the EDs may be best conceptualized as dimensional entities that are more similar than different. Despite optimism that the fifth edition of the DSM (DSM-5) would constitute a meaningful shift toward dimensional ED assessment and diagnosis, most changes contribute little movement in that direction. In the present report, we summarize past and anticipate persisting (i.e., in DSM-5) limitations of a purely categorical approach to ED diagnosis. We then review our alternative dimensional-categorical profile approach to ED assessment and classification, including preliminary evidence in support of its validity and presentation of two ED profile case examples using our newly developed Multidimensional Emotional Disorder Inventory. We end by discussing the transdiagnostic treatment implications of our profile approach to ED classification and directions for future research.

Abstract
Anxiety disorders belong to the most frequent mental disorders and are often characterized by an early onset and a progressive, persistent/chronic, or recurrent course. Several individual, familial, and environmental risk factors for adverse course characteristics of anxiety disorders (including higher persistence, lower probability of remission, and increased risk of recurrence) have been identified, and previous research suggests that clinical features of anxiety (e.g., higher severity, duration, and avoidance) as well as comorbid other mental disorders are particularly useful for predicting an unfavorable course of anxiety disorders. However, additional studies are needed to identify risk factors for individual course trajectories of anxiety disorders in general as well as specific diagnoses. Doing so is essential in order to more precisely identify individuals with anxiety disorders who are at increased risk for adverse long-term outcomes and might thus particularly profit from targeted early interventions.

Abstract
Limitations in anxiety and mood disorder diagnostic reliability and validity due to the categorical approach to classification used by the Diagnostic and Statistical Manual of Mental Disorders (DSM) have been long recognized. Although these limitations have led researchers to forward alternative classification schemes, few have been empirically evaluated. In a sample of 1,218 outpatients with anxiety and mood disorders, the present study examined the validity of Brown and Barlow's (2009) proposal to classify the anxiety and mood disorders using an integrated dimensional-categorical approach based on transdiagnostic emotional disorder vulnerabilities and phenotypes. Latent class analyses of 7 transdiagnostic dimensional indicators suggested that a 6-class (i.e., profile) solution provided the best model fit and was the most conceptually interpretable. Interpretation of the classes was further supported when compared with DSM diagnoses (i.e., within-class prevalence of diagnoses, using diagnoses to predict class membership). In addition, hierarchical multiple regression models were used to demonstrate the incremental validity of the profiles; class probabilities consistently accounted for unique variance in anxiety and mood disorder outcomes above and beyond DSM diagnoses. These results provide support for the potential development and utility of a hybrid dimensional-categorical profile approach to anxiety and mood disorder classification. In particular, the availability of dimensional indicators and corresponding profiles may serve as a useful complement to DSM diagnoses for both researchers and clinicians.

Abstract
While many studies have reported that individual differences in personality traits are genetically influenced, the neurobiological bases mediating these influences have not yet been well characterized. To advance understanding concerning the pathway from genetic variation to personality, here we examined whether measures of heritable variation in neuroanatomical size in candidate regions (amygdala and medial orbitofrontal cortex) were associated with heritable effects on personality. A sample of 486 middle-aged (mean=55 years) male twins (complete MZ pairs=120; complete DZ pairs=84) underwent structural brain scans and also completed measures of two core domains of personality: positive and negative emotionality. After adjusting for estimated intracranial volume, significant phenotypic (r(p)) and genetic (r(g)) correlations were observed between left amygdala volume and positive emotionality (r(p)=.16, p<.01; r(g)=.23, p<.05, respectively). In addition, after adjusting for mean cortical thickness, genetic and nonshared-environmental correlations (r(e)) between left medial orbitofrontal cortex thickness and negative emotionality were also observed (r(g)=.34, p<.01; r(e)=-.19, p<.05, respectively). These findings support a model positing that heritable bases of personality are, at least in part, mediated through individual differences in the size of brain structures, although further work is still required to confirm this causal interpretation.

Abstract
Previous research has shown that two dimensions of temperament referred to as neuroticism/behavioral inhibition (N/BI) and extraversion/behavioral activation (E/BA) are key risk factors in the development and maintenance of anxiety and mood disorders (Brown & Barlow, 2009). Given such findings, these temperamental dimensions may represent promising treatment targets for individuals with emotional disorders; however, to date, few studies have investigated the effects of psychological treatments on temperamental constructs generally assumed to be "stable, inflexible, and pervasive" (American Psychiatric Association, 2000). The present study addresses this gap in the literature by examining the effects of the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP; Barlow et al., 2011), a cognitive-behavioral therapy designed to target core processes of N/BI and E/BA temperaments, in a sample of adults with principal anxiety disorders and a range of comorbid conditions. Results revealed small effects of the UP on N/BI and E/BA compared with a waitlist control group at post-treatment. Additionally, decreases in N/BI and increases in E/BA during treatment were associated with improvements in symptoms, functioning, and quality of life. Findings provide preliminary support for the notion that the UP treatment facilitates beneficial changes in dimensions of temperament.

Abstract
A wealth of literature suggests that oxytocin is an important mediator of social cognition, but much of the research to date has relied on pharmaceutical administration methods that can raise oxytocin to artificially high levels. The present study builds upon previous work by examining whether basal oxytocin level predicts intra- and extra-personal (i.e., self- and other-focused) elements of emotional intelligence (EI), independent of shared variance with current mood. The sample included 71 healthy young adults (46 women). Assessment measures included the Mayer-Salovey-Caruso Emotional Intelligence Test Version 2.0 (MSCEIT), the Trait Meta-Mood Scale, and the Profile of Mood States. Peripheral oxytocin levels were examined with enzyme-linked immunosorbent assay from saliva after solid phase extraction. Oxytocin level was unrelated to TMMS scores but was positively associated with performance in the Experiential EI domain of the MSCEIT. However, total mood disturbance was positively related to MSCEIT scores. Hierarchical regression analysis indicated that oxytocin level added unique variance to the prediction of MSCEIT performance beyond that of current mood. These results confirm an association between endogenous levels of oxytocin in healthy adults and a subset of EI abilities, including extra-personal emotion recognition and the channeling of emotions to enhance social proficiency.

Abstract
Neuroticism and extraversion have been linked to the etiologies and course of anxiety and mood disorders, such that neuroticism is broadly associated with numerous disorders and extraversion is most strongly associated with social anxiety and depression. While previous research has established the broad associations between temperament and emotional disorders, less is known about the specific, proximal factors that are associated with them, and very few studies have situated these risk factors into a larger etiological model that specifies how they may relate to one another. The current study examined the interaction of extraversion and anxiety sensitivity (AS) in predicting social anxiety symptoms in a large, diagnostically diverse clinical sample (N=826). Symptoms were assessed with self-report and dimensional interview measures, and regression analyses were performed examining the main effects and interaction of extraversion and AS (examining both total and lower-order components) on social anxiety. Results showed that at higher levels of AS, the inverse relationship between extraversion and social anxiety was stronger, and the social concerns component of AS is responsible for this effect. This interaction was also observed with regard to depression symptoms, but the interaction was not present after accounting for shared variance (i.e., comorbidity) between depression and social anxiety symptoms. Clinical and theoretical implications of the results are discussed.

Abstract
Changes in personality trait levels often parallel episodes of major depressive disorder (MDD), whereas trait factor structures and substantial retest correlations are preserved. The authors explicated this dual state/trait nature of personality assessments among adults with recurrent MDD (N = 351) receiving cognitive therapy (CT) by testing stability and change with the Schedule for Nonadaptive and Adaptive Personality, 2nd Edition (SNAP-2; Clark, Simms, Wu, & Casillas, in press), separating state and trait variance, and predicting depressive symptoms and clinical outcomes. Many SNAP scale scores changed in CT (e.g., positive temperament increased, negative temperament decreased), and decreases in depressive symptoms accounted for most scales' score changes. Nonetheless, SNAP scales' state and trait components predicted depressive symptoms early and late in CT as well as clinical outcomes, and state components predicted changes in symptoms and clinical outcomes. These results support the validity of the SNAP-2 among depressed patients and highlight the salience of personalityrelevant state affect.

Abstract
Depression has robust associations with personality, showing a strong relation with neuroticism and more moderate associations with extraversion and conscientiousness. In addition, each Big Five domain can be decomposed into narrower facets. However, we currently lack consensus as to the contents of Big Five facets, with idiosyncrasies across instruments; moreover, few studies have examined associations with depression. In the current study, community participants completed six omnibus personality inventories; self-reported depressive symptoms were assessed at baseline and 5 years later. Exploratory factor analyses suggested three to five facets in each domain, and these facets served as prospective predictors of depression in hierarchical regressions, after accounting for baseline and trait depression. In these analyses, high anger (from neuroticism), low positive emotionality (extraversion), low conventionality (conscientiousness), and low culture (openness to experiences) were significant prospective predictors of depression. Results are discussed in regard to personality structure and assessment, as well as personality-psychopathology associations.
