Predicting Future Antisocial Personality Disorder in Males From a Clinical Assessment in Childhood.

It is essential to identify childhood predictors of adult antisocial personality disorder (APD) to target early prevention. It has variously been hypothesized that APD is predicted by childhood conduct disorder (CD), attention-deficit/hyperactivity disorder (ADHD), or both disorders. To test these competing hypotheses, the authors used data from a single childhood diagnostic assessment of 163 clinic-referred boys to predict future APD during early adulthood. Childhood Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev.; American Psychiatric Association, 1987) CD, but not ADHD, significantly predicted the boys' subsequent APD. An interaction between socioeconomic status (SES) and CD indicated that CD predicted APD only in lower SES families, however. Among children who met criteria for CD, their number of covert but not overt CD symptoms improved prediction of future APD, controlling for SES.

Longitudinal evidence that psychopathy scores in early adolescence predict adult psychopathy.

This study examined the relation between psychopathy assessed at age 13 by using the mother-reported Childhood Psychopathy Scale (D. R. Lynam, 1997) and psychopathy assessed at age 24 by using the interviewer-rated Psychopathy Checklist: Screening Version (PCL:SV; S. D. Hart, D. N. Cox, & R. D. Hare, 1995). Data from over 250 participants of the middle sample of the Pittsburgh Youth Study were used to examine this relation; approximately 9% of the sample met criteria for a possible PCL:SV diagnosis. Despite the long time lag, different sources, and different methods, psychopathy from early adolescence into young adulthood was moderately stable (r=.31). The relation was present for the PCL:SV total and facet scores, was not moderated by initial risk status or initial psychopathy level, and held even after controlling for other age 13 variables. Diagnostic stability was somewhat lower. Both specificity and negative predictive power were good, and sensitivity was adequate, but positive predictive power was poor. This constitutes the first demonstration of the relative stability of psychopathy from adolescence into adulthood and provides evidence for the incremental utility of the adolescent psychopathy construct. Implications and future directions are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Serious conduct problems in the children of adolescent mothers: Disentangling confounded correlations.

Early motherhood (r?=?.33) with the number of Diagnostic and Statistical Manual of Mental Disorders (DSM-III) symptoms of conduct disorder in a sample of 253 boys (aged 6–13 yrs) who had been referred to outpatient clinics. The following models were compared using path analysis: (1) Teenage motherhood, parental antisocial personality, and socioeconomic status (SES) each contribute uniquely to the prediction of childhood conduct problems; (2) teenage motherhood mediates the association of SES and parental antisocial personality with child conduct problems; and (3) teenage motherhood is spuriously related with child conduct problems because of common associations with SES and parental antisocial personality. Model (3) best fit the data. Similar results were obtained whether maternal age at the birth of the firstborn child or the proband child was used to define maternal age and when teenage motherhood was defined as giving birth at     

Bidirectional links and concurrent development of parent-child relationships and boys' offending behavior.

This study examined different types of longitudinal associations (i.e., directional links and overlapping developmental changes) between children's delinquency and the quality of parent–child relationships from middle childhood to late adolescence. We used 10-wave interview data of 503 boys, their primary caregivers, and their teachers. Our first aim was to unravel the direction of effects between parent–child relationships and children's offending. Cross-lagged panel models revealed bidirectional links over time between poorer quality parent–child relationships and boys' offending across late childhood (age 7–10), early adolescence (age 10–13) and middle adolescence (age 13–16). Second, we examined the associations between mean changes in delinquency, on the one hand, and mean changes in relationship quality, on the other hand. Although parent–child relationships improved during childhood, their quality decreased in early adolescence and remained stable in middle adolescence. Delinquency increased only in middle adolescence. In five out of six models, the slope factors of relationship quality and offending were strongly correlated, indicating that stronger increases in delinquency were associated with stronger decreases in parent–child relationship quality across childhood, early adolescence, and middle adolescence. The discussion focuses on the theoretical implications of these two types of longitudinal associations. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Inattention as a key predictor of tobacco use in adolescence.

The authors examined the prediction from inattention to tobacco use among 2 cohorts (ages 7 and 13) of a community sample followed to young adulthood. Changes in self-reported tobacco use were tested with marginal transitional regression models, using parent and teacher ratings of inattention, hyperactivity-impulsivity, and other psychopathology, along with other factors, as predictors. Inattention, but not hyperactivity-impulsivity, significantly predicted adolescent tobacco use and young adult daily tobacco use. Peer substance use, parental substance use, and conduct disorder also predicted increases in tobacco use. African American ethnicity was strongly protective against later tobacco use.

Four-year longitudinal study of conduct disorder in boys: Patterns and predictors of persistence.

A prospective study of conduct disorder (CD) was conducted using 4 annual structured diagnostic interviews of 171 clinic-referred boys, their parents, and their teachers. Only about half of the 65 boys who met criteria for CD in Year 1 met criteria again during the next year, but 88% met criteria for CD again at least once during the next 3 years. For most boys with CD, the number of symptoms fluctuated above and below the diagnostic threshold from year to year but remained relatively high. Lower socioeconomic status, parental antisocial personality disorder (APD), and attention-deficit hyperactivity disorder were significant correlates of CD in Year 1, but the interaction of parental APD and the boy's verbal intelligence predicted the persistence of CD symptoms over time (i.e., only boys without a parent with APD and with above-average verbal intelligence clearly improved).

"Academic underachievement and the disruptive behavior disorders": Correction.

Reports an error in the original article by P. J. Frick et al (Journal of Consulting and Clinical Psychology, 1991, Vol 59[2], 289–294). The correct formula to calculate the discrepancy score between IQ and academic achievement, Step 3, is provided. (The following abstract of this article originally appeared in record 1991-21350-001.) Academic underachievement (AU) was studied among 177 clinic-referred boys (aged 7–12 yrs) reliably diagnosed as having attention-deficit hyperactivity disorder (ADHD) or conduct disorder (CD). Unlike previous studies, the present study assessed AU using a formula that determined the discrepancy between a child's predicted level of achievement and actual level of achievement while controlling for regression and age effects. AU was associated with both ADHD and CD when the disorders were examined individually. However, when examined in multivariate logit model analyses, the apparent relation between CD and AU was found to be due to its comorbidity with ADHD. When boys with ADHD were divided into those with attention deficits only and those with co-occurring hyperactivity, findings did not support the hypothesis that the association with AU is stronger for attention deficits without co-occurring hyperactivity.

Criterion validity of informants in the diagnosis of disruptive behavior disorders in children: A preliminary study.

The relative validity of the reports of parents, teachers, and children, and combinations of these informants was assessed using measures of concurrent impairment associated with disruptive behavior disorders as criterion variables in a clinic-referred sample of 177 boys ages 7–12 years. For oppositional defiant disorder (ODD) and conduct disorder (CD), the reports from teachers, alone and in combination with parents and children, showed the strongest relations to impairment criteria. The reports of parents and children, alone and in combination, were relatively less valid. For attention-deficit hyperactivity disorder, there were no significant correlations between the reports of any single informant or combination of informants and the impairment criteria. This study provides preliminary support for the validity of multi-informant diagnostic assessment of ODD and CD in children, especially when the teacher is one of the informants.

Bituminous emulsions and their characterization by atomic force microscopy

We present a new method for observing oil-in-water emulsions with a continuous water phase and a dispersed bitumen phase. The fine polydispersed bitumen micelles were adsorbed to an atomically smooth mica substrate and imaged in solution by atomic force microscopy in a liquid cell. The height of the adsorbed bitumen sheet in wet and dry states can be measured and the homogeneity of film formation by coalescence can be determined. Localization of surfactant onto and between bitumen micelles is also visualized.     

Association of parental psychopathology to the comorbid disorders of boys with attention deficit-hyperactivity disorder.

This study examined whether particular forms of parental psychopathology are related to similar forms of comorbid psychopathology in offspring with attention deficit-hyperactivity disorder (ADHD). Parental disorders were assessed using maternal interviews, and child disorders were assessed using multiple-informant interviews for 111 clinic-referred boys (aged 7–12) with Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev.: American Psychiatric Association, 1987) ADHD. Associations between parental and child internalizing disorders and between parental and child externalizing disorders were found, but associations across categories of disorder (i.e., internalizing and externalizing) were not. Similar relationships were observed in 66 clinic-referred boys without ADHD. These findings support specific modes of familial transmission, in contrast to theories that comorbidity simply reflects more severe psychopathology in children with ADHD.
