BACKGROUND The Child Behavior Checklist Juvenile Bipolar Disorder (CBCL-JBD) profile and Posttraumatic Stress Problems (CBCL-PTSP) scale have been used to assess juvenile bipolar disorder (JBD) and posttraumatic stress disorder (PTSD), respectively. However, their validity is questionable according to previous research. Both measures are associated with severe psychopathology often encompassing multiple DSM-IV diagnoses. Further, children who score highly on one of these scales often have elevated scores on the other, independent of PTSD or JBD diagnoses. We hypothesized that the two scales may be indicators of a single syndrome related to dysregulated mood, attention, and behavior. We aimed to describe and identify the overlap between the CBCL-JBD profile and CBCL-PTSP scales. METHOD Two thousand and twenty-nine (2029) children from a nationally representative sample (1073 boys, 956 girls; mean age = 11.98; age range = 6-18) were rated on emotional and behavior problems by their parents using the CBCL. Comparative model testing via structural equation modeling was conducted to determine whether the CBCL-JBD profile and CBCL-PTSP scale are best described as measuring separate versus unitary constructs. Associations with suicidality and competency scores were also examined. RESULTS The CBCL-JBD and CBCL-PTSP demonstrated a high degree of overlap (r = .89) at the latent variable level. The best fitting, most parsimonious model was one in which the CBCL-JBD and CBCL-PTSP items identified a single latent construct, which was associated with higher parental endorsement of child suicidal behavior, and lower functioning. CONCLUSIONS The CBCL-JBD profile and CBCL-PTSP scale overlap to a remarkable degree, and may be best described as measures of a single syndrome. This syndrome appears to be related to severe psychopathology, but may not conform to traditional DSM-IV classification. These results contribute to the ongoing debate about the utility of the CBCL-JBD and CBCL-PTSP profiles, and offer promising methods of empirically based measurement of disordered self-regulation in youth.

The Dysregulation Profile (DP) of the Child Behavior Checklist (CBCL) (previously called the CBCL-Juvenile Bipolar Disorder or CBCL-JBD profile) characterized by elevated scores on CBCL attention problems, aggressive behavior, and anxious/depressed scales is associated with severe psychopathology and suicidal behavior. The stability of this profile across informants has not been established. In this study, agreement across parent, teacher, and self-reports was examined for the Dysregulation Profile phenotype derived using latent class analysis of a national probability sample of 2031 children aged 6-18. The Dysregulation Profile latent class was found for each informant and accounted for 6-7% of the sample. There was mild to fair agreement on the Dysregulation Profile latent class between parents and youth (Kappa=0.22-0.25), parents and teachers (Kappa=0.14-0.24) and youth and teachers (Kappa=0.19-0.28). When parents and youth reports both placed children into the Dysregulation Profile latent class, 42% of boys and 67% of girls reported suicidal thoughts or behavior. We conclude that the Dysregulation Profile latent class is identified across informants although agreement of specific individuals is mild. Children in this class as identified by parental and youth reports have a very high risk for suicidal thoughts and behaviors.

OBJECTIVE To test the association between the catechol-O-methyltransferase (COMT) Val158Met polymorphism and both aggressive behavior and attention problems in youth. We hypothesized that youth carrying a Met allele would have greater average aggressive behavior scores, and that youth exhibiting Val-homozygosity would have greater average attention problems scores. METHOD Complete data on maternally rated Child Behavior Checklist (CBCL) measures of aggressive behavior (AGG) and attention problems (AP), COMT polymorphism data, demographics, and maternal parenting quality were available for 149 youth (6 to 18 years old). Multivariable linear regression models were used to test the degree to which youth COMT Val158Met genotype was associated with AGG and AP while statistically controlling for age, gender, parental socioeconomic status (SES), and maternal parenting quality from the Alabama Parenting Questionnaire. RESULTS Mothers of Met-carriers rated their children higher on average AGG scores when compared with mothers of Val-homozygotes (p = .016). Further analyses revealed that this association was even more robust for maternal ratings of direct aggression (p = .007). The hypothesized association between Val-homozygosity and higher average AP scores relative to average AP scores of Met-carriers did not quite reach statistical significance (p = .062). CONCLUSIONS After controlling for demographics, SES, and maternal parenting quality as confounders, there remains a strong association between youth carrying a Met allele and higher average AGG scores relative to Val-homozygotes.

OBJECTIVE To identify latent classes of posttraumatic stress disorder (PTSD) symptoms in a national sample of adolescents, and to test their associations with PTSD and functional impairment 1 year later. METHOD A total of 1,119 trauma-exposed youth aged 12 through 17 years (mean = 14.99 years, 51% female and 49% male) participating in the National Survey of Adolescents-Replication were included in this study. Telephone interviews were conducted to assess PTSD symptoms and functional impairment at Waves 1 and 2. RESULTS Latent Class Analysis revealed three classes of adolescent PTSD at each time point: pervasive disturbance, intermediate disturbance, and no disturbance. Three numbing and two hyperarousal symptoms best distinguished the pervasive and intermediate disturbance classes at Wave 1. Three re-experiencing, one avoidance, and one hyperarousal symptom best distinguished these classes at Wave 2. The Wave 1 intermediate disturbance class was less likely to have a PTSD diagnosis, belong to the Wave 2 pervasive disturbance class, and report functional impairment 1 year later compared with the Wave 1 pervasive disturbance class. The Wave 1 no disturbance class was least likely to have PTSD, belong to the pervasive disturbance class, and report functional impairment at Wave 2. CONCLUSIONS This study suggests that PTSD severity-distinguishing symptoms change substantially in adolescence and are not characterized by the numbing cluster, contrary to studies in adult samples. These results may help to explain inconsistent factor analytic findings on the structure and diagnosis of PTSD, and emphasize that developmental context is critical to consider in both research and clinical work in PTSD assessment and diagnosis.

BACKGROUND Research on the relation of stress to alcohol consumption is inconsistent regarding the direction of effects, and this association has been shown to vary by sex and type of stress. We sought to build upon the stress-drinking literature by examining the direction of the stress-drinking association over time as well as sex and stressor differences using daily data. METHOD 246 heavy drinking adults (67% men) aged 21-82 reported daily stress levels and alcohol consumption over 180 days using Interactive Voice Response (IVR). Baseline daily hassles were examined as an alternative measure of stress. Generalized estimating equations (GEEs) were conducted to test the stress-drinking association accounting for alcohol dependency at baseline and sex and stressor type as moderators. RESULTS IVR daily stress predicted increased alcohol consumption the following day, whereas baseline level of daily hassles did not. Examining the opposite direction of effects, IVR ratings of daily alcohol consumption predicted decreased next-day stress. Stress predicted higher alcohol consumption the next day for men but there was no significant association for women. For both sexes, drinking predicted decreased stress the next day, but this effect was stronger for women. CONCLUSIONS This study generally supported the drinking to cope and self-medication hypotheses, with findings that increased stress led to increased drinking. The time-varying relation between stress and alcohol appears to be sex- and measure-specific, however. Therefore, interventions targeted at stress management found to be effective for one sex should not be presumed to be applicable to the other.

It is crucial to characterize self-regulation in children. We compared the temperamental profiles of children with the Child Behavior Checklist (CBCL) Dysregulation Profile (CBCL-DP) to profiles associated with other CBCL-derived syndromes. 382 children (204 boys; aged 5–18) from a large family study were examined. Temperamental profiles were based on the Juvenile Temperament and Character Inventory. Children with the CBCL-DP had a temperamental profile characterized by high Novelty Seeking, high Harm Avoidance, low Reward Dependence and low Persistence. Linear mixed models and regression-based models demonstrated that the CBCL-DP was associated with a “disengaged” temperamental profile. This profile is similar to the profile seen in adult disorders of self-regulation, including cluster B personality disorders. These results support the hypothesis that the CBCL-DP measures poor self-regulation.

This study examined hostility and harsh discipline of both mothers and fathers as potential mechanisms explaining the association between a maternal maltreatment history and her offspring’s internalizing and externalizing problems. Prospective data from fetal life to age 6 were collected from a total of 4,438 families participating in the Generation R Study. Maternal maltreatment was assessed during pregnancy using a self-administered questionnaire. Mothers and fathers each reported on their psychological distress and harsh discipline when the child was 3 years. Children’s internalizing and externalizing problems were assessed by parental reports and child interview at age 6. Findings from structural equation modeling showed that the association between a maternal maltreatment history and her offspring’s externalizing problems was explained by maternal hostility and harsh discipline and, at least partially, also by paternal hostility and harsh discipline. Child interview data provided support for both these indirect paths, with associations largely similar to those observed for parent reports.

A four-factor structure of posttraumatic stress disorder (PTSD) has been proposed for DSM-V based on empirical evidence that it is superior to the three-factor DSM-IV structure. However, most studies reveal multiple structures fit the data well in adolescent samples, and high factor correlations have been reported. Within two national samples of adolescents, we tested eight PTSD factor structures, which have never been compared in a single study. Confirmatory factor analyses (CFA) of PTSD symptoms were conducted in two national samples of adolescents: the National Survey of Adolescents (NSA; N = 4023) and the NSA-Replication (NSA-R; N = 3614). CFA revealed that all models provided very good fit to both samples (RMSEAs = .021-.039), though the one-factor model can be rejected, and correlations between factors were high (rs = .80-1.0). Potential interpretations of these findings include: (1) the indicators (i.e., symptoms) need refinement; or (2) relevant symptoms have yet to be identified.

This study examines the role of abuse-specific maternal support in the association between parent depressive symptoms and child externalizing problems in a sample of children with a history of sexual abuse. In total, 106 mother–child dyads were studied. The association between maternal depressive symptoms and child delinquency behaviors was found to partially operate through abuse-specific maternal support, which was assessed via parent report. Implications of the findings for parenting programs are discussed, and future research directions are considered.

AIMS The goal of this study was to better understand the predictive relationship in both directions between negative (anger, sadness) and positive (happiness) moods and alcohol consumption using daily process data among heavy drinkers. METHODS Longitudinal daily reports of moods, alcohol use and other covariates such as level of stress were assessed over 180 days using interactive voice response telephone technology. Participants were heavy drinkers (majority meeting criteria for alcohol dependence at baseline) recruited through their primary care provider. The sample included 246 (166 men, 80 women) mostly Caucasian adults. Longitudinal statistical models were used to explore the varying associations between number of alcoholic drinks and mood scores the next day and vice versa with gender as a moderator. RESULTS Increased alcohol use significantly predicted decreased happiness the next day (P < 0.005), more strongly for females than males. Increased anger predicted higher average alcohol use the next day for males only (P < 0.005). CONCLUSION This daily process study challenges the notion that alcohol use enhances positive mood for both males and females. Our findings also suggest a strong association between anger and alcohol use that is specific to males. Thus, discussions about the effects of drinking on ones feeling of happiness may be beneficial for males and females as well as anger interventions may be especially beneficial for heavy-drinking males.
