RESUMEN
OBJECTIVE: Research examining relationships between trait Openness to Experience, psychopathology, and well-being has produced contradictory findings. Examining temporary manifestations of Openness may provide further insight into the interplay between Openness and symptoms in clinical populations. METHOD: The present study validated a brief new measure to assess daily Openness in 271 adults (Mage = 34 years, 52% women, 83% White) taking part in 7 days of intensive treatment for acute psychopathology. Participants also completed a daily measure of depressive symptoms. RESULTS: Participants overall experienced a significant but small increase in daily Openness during treatment. Two latent classes best characterized initial levels and trajectories of Openness in this sample: medium/increase (86% of sample) and low/decrease (14%). Daily Openness negatively related to depressive symptoms over the entire course of treatment and at the daily level. Daily Openness, however, did not predict depressive symptoms from one day to the next (or vice versa). CONCLUSIONS: Results of this study contribute to the scientific understanding of positive personality change during challenging life circumstances. Future research could examine whether targeting Openness as part of treatment holds clinical value. Findings are limited by this study's short time frame and the lack of ethnoracial diversity in this sample.

OBJECTIVE: Research on sources of variation in adolescent's gonadal hormone levels is limited. We sought to decompose individual differences in adolescent testosterone, estradiol, and pubertal status, into genetic and environmental components. DESIGN: A sample of male and female adolescent twins from the greater Austin and Houston areas provided salivary samples, with a subset of participants providing longitudinal data at 2 waves. PARTICIPANTS: The sample included 902 adolescent twins, 49% female, aged 13-20 years (M = 15.91) from the Texas Twin Project. Thirty-seven per cent of twin pairs were monozygotic; 30% were same-sex dizygotic (DZ) pairs; and 33% were opposite-sex DZ pairs. MEASUREMENTS: Saliva samples were assayed for testosterone and estradiol using chemiluminescence immunoassays. Pubertal status was assessed using self-report. Biometric decompositions were performed using multivariate quantitative genetic models. RESULTS: Genetic factors contributed substantially to variation in testosterone in males and females in the follicular phase of their menstrual cycle (h2 = 60% and 51%, respectively). Estradiol was also genetically influenced in both sexes, but was predominately influenced by nonshared environmental factors. The correlation between testosterone and estradiol was mediated by a combination of genetic and environmental influences for males and females. Genetic and environmental influences on hormonal concentrations were only weakly correlated with self-reported pubertal status, particularly for females. CONCLUSIONS: Between-person variability in adolescent gonadal hormones and their interrelationship reflects both genetic and environmental processes, with both testosterone and estradiol containing sizeable heritable components.

Interpersonal stress arising from relational aggression (RA)-the intentional effort to harm others via rejection and exclusion-may increase risk for depression in youth. Biological vulnerabilities related to the hormone oxytocin, which affects social behavior and stress responses, may exacerbate this risk. In a community sample of 307 youth (52% female; age range = 10-14 years), we tested whether (1) the association between RA and subsequent depressive symptoms was mediated through social problems and (2) a single nucleotide polymorphism (rs53576) in the oxytocin receptor gene (OXTR) moderated this indirect association between RA and depression, where GG homozygotes are predicted to be more sensitive to the effects of social problems than A-allele carriers. Youth-reported RA and depressive symptoms were measured using a structured interview and a questionnaire, respectively. DNA was extracted from saliva collected with Oragene kits. Consistent with the interpersonal theory of depression, the association between relational aggression and subsequent depressive symptoms was mediated by social problems. This indirect effect was further moderated by rs53576 genotype, such that GG homozygotes showed a stronger mediation effect than A-carriers. These results suggest that rs53576 variants confer vulnerability for depression within the context of interpersonal risk factors, such that youth with the GG genotype may be particularly sensitive to the social consequences resulting from RA.

BACKGROUND: Structural models of oppositional defiant disorder (ODD) symptoms have gained empirical support but await greater empirical scrutiny on issues such as reconciliation between competing models, evidence for gender differences, and delineation of external correlates. More extensive validation evidence is particularly necessary in consideration of their incorporation in psychiatric nomenclature. METHODS: We fitted previously proposed, but competing, models to ODD symptoms assessed with the Computerized Diagnostic Interview Schedule for Children (Shaffer et al., 2000, J. Am. Acad. Child Adolesc. Psychiatry, 39, 28) in a community sample and then fitted the best-fitting model in a replication sample (combined N = 730, Mage = 9.89, SD = 0.75). Analyses also examined potential classes based on resulting subfactors, gender differences, longitudinal associations with later behavioral problems, and concurrent personality associations. RESULTS: Burke's (2010) two-factor model composed of Irritability and Oppositionality subfactors best fit the data. Irritability and Oppositionality showed convergent and divergent patterns of association with personality traits at T1 and with externalizing and internalizing problems at T2. Latent class analyses revealed three classes (low severity, irritable/combined, and oppositional) which showed parallel divergence in externalizing and internalizing problem comorbidity. These findings were largely robust across gender and samples. CONCLUSIONS: These findings support Irritability/Oppositionality subfactors of ODD in two mixed-gender samples, demonstrate strong evidence for a lack of gender differences in such subfactors, and demonstrate their convergent and divergent validity in emergent latent classes, later behavioral problems, and personality correlates.
RESUMEN
Previous investigations of testosterone and externalizing behavior have provided mixed findings. We tested the hypothesis that self-regulatory personality moderates the testosterone-externalizing behavior association in adolescence. Parents reported on their 13- to 18-year-old (N = 106, Mage = 16.01, SD = 1.29) children's personalities and psychopathology. Testosterone was measured via drool samples. As hypothesized, personality moderated the testosterone-externalizing behavior association. High testosterone predicted higher levels of externalizing behaviors, but only for adolescents low in Agreeableness and Conscientiousness. Also, personality acted as a resiliency factor: high levels of Conscientiousness, in the presence of high testosterone, predicted lower levels of rule breaking. Results highlight how endogenous factors, such as personality, may interact with testosterone, and emphasize the relevance of including personality moderators in future research.

Dispositional trait frameworks offer great potential to elucidate the nature and development of psychopathology, including the construct of relational aggression. The present study sought to explore the dispositional context of relational aggression across three dispositional frameworks: temperament, personality, and personality pathology. Participants comprised a large community sample of youth, aged 6 to 18 years (N = 1,188; 51.2% female). Ratings of children's relational aggression, temperament, personality, and personality pathology traits were obtained through parent report (86.3% mothers). Results showed convergence and divergence across these three dispositional frameworks. Like other antisocial behavior subtypes, relational aggression generally showed connections with traits reflecting negative emotionality and poor self-regulation. Relational aggression showed stronger connections with temperament traits than with personality traits, suggesting that temperament frameworks may capture more relationally aggressive content. Findings at the lower order trait level help differentiate relational aggression from other externalizing problems by providing a more nuanced perspective (e.g., both sociability and shyness positively predicted relational aggression). In addition, there was little evidence of moderation of these associations by gender, age, or age2, and findings remained robust even after controlling for physical aggression. Results are discussed in the broader context of conceptualizing relational aggression in an overarching personality-psychopathology framework.

Although personality disorder characteristics are often grouped with externalizing problems in adults, little is known about the extent to which they define the externalizing spectrum in youth. We examined the extent to which personality pathology traits in youth reflected common and specific variance in externalizing problems and explored differentiation of these connections by age. Parents reported on physical aggression, rule-breaking, relational aggression, and personality pathology traits for 1080 youth (48.8% male) ages 6-18 years. Disagreeableness and emotional instability traits were correlated with a general externalizing factor as well as with specific behavioral subfactors. The magnitude of these correlations varied across age, with the highest magnitude evidenced during the developmental periods of greatest prevalence for the specific externalizing behavior subtype. Taken together, these findings suggest that personality pathology is tightly connected with externalizing problems in youth, especially during developmental periods when externalizing problems are common.

Personality variability is an important individual difference construct that is the focus of major psychological theories and relates to socioemotional functioning. Although cross-situational personality variability has been studied extensively in adult populations, little is known about variability in children's personality. In this study, we aimed to address this gap in knowledge by evaluating whether cross-situational variability is a potentially meaningful individual difference in youth. We used a "thin slice" approach in which research assistants viewed videos of 324 children (Mage = 9.92) completing 15 standardized tasks and rated youth's Big Five personality states. Cross-situational variability in each personality state was estimated by calculating within-person standard deviations across tasks. Results showed that (a) there is substantial variability in children's personality states; (b) children who are variable in one personality domain tend to be variable in other domains; and (c) more variable children are described by their parents as being less competent, less agreeable, less conscientious, and more neurotic. However, associations with parent-rated external criterion were generally small in magnitude, and key psychometric properties of the thin slice personality variability index are not well-established. Our study adds tentative but promising evidence that individual differences in cross-situational personality variability are not only present in childhood but may be consequential.

The transition to adolescence is marked by enormous change in social, biological, and personality development. Although accumulating evidence has offered insight into the nature of higher-order personality trait development during this period, much less is known about the development of lower-order personality traits, or "facets." The current study used a cohort-sequential longitudinal design to examine domain- and facet-level trajectories for mother-reported personality traits during the early adolescent transition. Personality trait domains and facets were assessed with the Inventory of Child Individual Differences-Short Form (Deal, Halverson, Martin, Victor, & Baker, 2007). Participants were 440 children followed at 4 annual timepoints from middle childhood (Mage = 9.97, SD = 0.81) to early adolescence (Mage = 13.11, SD = 0.84). Results of latent growth curve models showed substantial facet-level personality stability in this period, as well as small to moderate linear change in 13 of 15 facets. Gender differences in change were evident for 9 facets. Overall patterns suggested consistent increases in agreeableness facets with null to small gender differences. Neuroticism and openness to experience facet change was heterogeneous within each domain, but patterns were similar for boys and girls. Extraversion primarily decreased, though the magnitude and direction of change differed between facets and genders. Conscientiousness increased across all facets, but only among girls. These findings overall demonstrate a high degree of developmental consistency in facets within each domain as well as some notable differences. Further, this study contributes to a small and somewhat mixed evidence base for current theories of adolescent personality development. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Low agreeableness features centrally in personality profiles of Cluster B personality disorder (PD) diagnoses, and it has been associated with relational aggression (RAgg; intentionally damaging others' social relationships). Researchers have hypothesized that RAgg may be a potential developmental precursor for Cluster B PDs. However, a dimensional approach to personality dysfunction is preferable to the categorical system found in the current diagnostic manual. To build a bridge between two disjointed literatures (categorical PDs and RAgg), the aim of this project is to detail how RAgg in youth is situated in the trait space represented by disagreeableness in a dimensional model of personality pathology. Caregivers of 911 youth (ages 6-18) reported on youth's RAgg and disagreeableness. We found that RAgg was most strongly related to three facets: Narcissistic traits, Hyperexpressive traits, and Dominance-Egocentrism traits. Overall, these findings provide support for RAgg as an early manifestation of personality pathology, particularly for narcissistic traits.

Recent research has illustrated the utility and accuracy of a thin-slice (TS) approach to child personality assessment, whereby unacquainted observers provide personality ratings of children after exposure to brief behavioral episodes. The current study sought to expand on this approach by exploring formal multitrait-multimethod (MTMM) models for child TS data comprising ratings from a comprehensive set of TS situations. Results using data from a sample of 326 community children 9-10 years of age indicated that a correlated traits, correlated methods (CTCM) model can be used to represent individual differences in children's behavior as manifest across different situations. Indicator variables derived from a CTCM differentially correlated with traditional parental ratings of behavior, moreover, and provide predictive and incremental validity regarding child competencies and behavior. Results illustrate the utility of a TS approach in the assessment of childhood personality and inform understanding of issues encountered in applying different MTMM models to these types of empirical data.

Although an emphasis on adequate sample size and statistical power has a long history in clinical psychological science (Cohen, 1992), increased attention to the replicability of scientific findings has renewed focus on the importance of statistical power (Bakker, van Dijk, & Wicherts, 2012). These recent efforts have not yet circled back to modern clinical psychological research, despite the importance of sample size and power in producing a credible body of evidence. As one step in this process of scientific self-examination, the present study estimated an N-pact Factor (the statistical power of published empirical studies to detect typical effect sizes; Fraley & Vazire, 2014) in 2 leading clinical journals (the Journal of Abnormal Psychology [JAP] and the Journal of Consulting and Clinical Psychology [JCCP]) for the years 2000, 2005, 2010, and 2015. Study sample size, as one proxy for statistical power, is a useful focus because it allows comparisons with other subfields and may highlight some of the core methodological differences between clinical and other areas. We found that, across all years examined, the average median sample size in clinical research was 179 participants (175 for JAP and 182 for JCCP). The power to detect a small to medium effect size of .20 is just below 80% for both journals. Although the clinical N-pact factor was higher than that estimated for social psychology, the statistical power in clinical journals is still limited to detect many effects of interest to clinical psychologists, with little evidence of improvement in sample sizes over time.

Recent efforts have demonstrated that thin-slice (TS) assessment-or assessment of individual characteristics after only brief exposure to that individual's behaviour-can produce reliable and valid measurements of child personality traits. The extent to which this approach can be generalized to archival data not designed to measure personality, and whether it can be used to measure personality pathology traits in youth, is not yet known. Archival video data of a parent-child interaction task was collected as part of a clinical intervention trial for aggressive children (N = 177). Unacquainted observers independently watched the clips and rated children on normal-range (neuroticism, extraversion, agreeableness, conscientiousness and openness to experience) and pathological (callous-unemotional) personality traits. TS ratings of child personality showed strong internal consistency, valid associations with measures of externalizing problems and temperament, and revealed differentiated subgroups of children based on severity. As such, these findings demonstrate an ecologically valid application of TS methodology and illustrate how researchers and clinicians can extend their existing data by measuring child personality using TS methodology, even in cases where child personality was not originally measured.

OBJECTIVE: Race/ethnicity and socioeconomic status are both associated with stress physiology as indexed by cortisol. The present study tested the extent to which racial/ethnic disparities in cortisol reactivity are explained by socioeconomic status. METHOD: The sample consisted of 296 racially and socioeconomically diverse children ages 8-11 (47% boys). Mothers reported on children's stressors and socioeconomic status; salivary cortisol levels were assessed before and after the Trier Social Stress Test. RESULTS: Results demonstrated that racial group differences in cortisol reactivity were partially accounted for by differences in socioeconomic status, but racial group differences in cortisol recovery were not. CONCLUSIONS: These findings suggest that cumulative effects of stress and disadvantage may result in differences in stress response physiology as early as middle childhood, and that race-specific mechanisms account for additional variance in cortisol reactivity and recovery.

The dual systems model posits that adolescent risk-taking results from an imbalance between a cognitive control system and an incentive processing system. Researchers interested in understanding the development of adolescent risk-taking use a diverse array of behavioral and self-report measures to index cognitive control and incentive processing. It is currently unclear whether different measures commonly interpreted as indicators of the same psychological construct do, in fact, tap the same underlying dimension of individual differences. In a diverse sample of 810 adolescent twins and triplets (M age=15.9years, SD=1.4years) from the Texas Twin Project, we investigated the factor structure of fifteen self-report and task-based measures relevant to adolescent risk-taking. These measures can be organized into four factors, which we labeled premeditation, fearlessness, cognitive dyscontrol, and reward seeking. Most behavioral measures contained large amounts of task-specific variance; however, most genetic variance in each measure was shared with other measures of the corresponding factor. Behavior genetic analyses further indicated that genetic influences on cognitive dyscontrol overlapped nearly perfectly with genetic influences on IQ (rA=-0.91). These findings underscore the limitations of using single laboratory tasks in isolation, and indicate that the study of adolescent risk taking will benefit from applying multimethod approaches.

The present study examined whether thin-slice ratings of child personality serve as a resource-efficient and theoretically valid measurement of child personality traits. We extended theoretical work on the observability, perceptual accuracy, and situational consistency of childhood personality traits by examining intersource and interjudge agreement, cross-situational consistency, and convergent, divergent, and predictive validity of thin-slice ratings. Forty-five unacquainted independent coders rated 326 children's (ages 8-12) personality in 1 of 15 thin-slice behavioral scenarios (i.e., 3 raters per slice, for over 14,000 independent thin-slice ratings). Mothers, fathers, and children rated children's personality, psychopathology, and competence. We found robust evidence for correlations between thin-slice and mother/father ratings of child personality, within- and across-task consistency of thin-slice ratings, and convergent and divergent validity with psychopathology and competence. Surprisingly, thin-slice ratings were more consistent across situations in this child sample than previously found for adults. Taken together, these results suggest that thin slices are a valid and reliable measure to assess child personality, offering a useful method of measurement beyond questionnaires, helping to address novel questions of personality perception and consistency in childhood.

Growing evidence has indicated that gonadal and stress hormones interact to shape socially dominant behavior and externalizing psychopathology; however, such work to date has focused exclusively on the testosterone-cortisol interaction, despite expectations that estradiol should be associated with similar behavioral outcomes to testosterone. Here, we present the first empirical test of the hypothesis that adolescent males and females (N=105, ages 13-18) with high estradiol and low cortisol concentrations are at highest risk for externalizing problems, but - replicating previous work - only among adolescents high on pathological personality traits. Parents reported on youth psychopathology and personality, and hormone concentrations were measured via passive drool. Results confirmed the hypothesis: high estradiol was associated with more externalizing behaviors, but only when cortisol was low and personality traits of disagreeableness and emotional instability were high. Further, these associations held when controlling for testosterone concentrations. These findings provide the first empirical evidence of a hypothalamic pituitary adrenal (HPA)×hypothalamic pituitary gonadal (HPG) axis interaction that extends the "dual hormone" hypothesis beyond testosterone.

The "dual-hormone" hypothesis predicts that testosterone and cortisol will jointly regulate aggressive and socially dominant behavior in children and adults (e.g., Mehta & Josephs, 2010). The present study extends research on the dual-hormone hypothesis by testing the interaction between testosterone, cortisol, and personality disorder (PD) traits in predicting externalizing problems in a community sample of adolescent males and females. Participants were 106 youth from the community, ranging in age from 13-18 (Mage = 16.01 years, SDage = 1.29), and their parents. Parents and youth provided ratings on an omnibus measure of personality pathology and externalizing problems. Youth provided saliva samples via passive drool from which testosterone and cortisol levels were obtained. Robust moderation of the joint effects of testosterone and cortisol on parent-reported externalizing problems was found for both higher-order PD traits associated with externalizing psychopathology (Disagreeableness and Emotional Instability). Higher testosterone was associated with externalizing outcomes, but only when cortisol was low, and only among youth with high levels of Disagreeableness and Emotional Instability. These findings provide the first evidence for the dual-hormone hypothesis in a mixed-sex sample of community adolescents, but importantly offer novel evidence for the importance of personality traits. Examination of the joint regulation of externalizing problems by testosterone and cortisol in the context of adolescent personality may help to clarify inconsistent main effects of testosterone and cortisol on clinical externalizing phenotypes.

At present, no single attention-deficit/hyperactivity disorder (ADHD) measure completely and comprehensively captures all ADHD diagnostic criteria (Anastopoulos, 2001). This represents a notable limitation in the assessment of attention problems and suggests the need for research that reconciles differences in information across measures purporting to measure the same or similar constructs. For example, by analyzing differences in measures in relation to a third construct, the third construct can provide an illuminative backdrop against which to view and ultimately reconcile differences between measures of the same attention problem construct. Thus, the purpose of the present study was to draw on a dispositional trait framework to illustrate differences in the ADHD construct assessed by 2 widely used attention problem measures. Parents of 346 children (51% girls) ranging in age from 7 to 12 years (M = 9.92 years, SD = 0.83 years) completed the Child Behavior Checklist (CBCL; Achenbach & Rescorla, 2001), a structured clinical interview based on the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; DSM-IV-TR; American Psychiatric Association, 2000), and dispositional trait questionnaires about their child. Both low Conscientiousness/Effortful Control and high Neuroticism/Negative Affect showed strong, unique associations with the CBCL Attention Problem score, whereas only low Conscientiousness/Effortful Control showed a strong, unique association with DSM-IV-TR ADHD symptoms assessed by clinical interview. These discriminant dispositional trait correlates help us understand the nature of the attention problem construct as assessed by each measure, with important implications for the practice of cross-measure integration in both research and applied settings.
