Who disrupts from placement in foster and kinship care?

OBJECTIVE: To identify reliable, inexpensive predictors of foster care placement disruption that could be used to assess risk of placement failure. METHODS: Using the Parent Daily Report Checklist (PDR), foster or kinship parents of 246 children (5-12 years old) in California were interviewed three times about whether or not their foster child engaged in any of the 30 problem behaviors during the previous 24 h. PDR was conducted during telephone contacts (5-10 min each) that occurred from 1 to 3 days apart at baseline. Disruptions were tracked for the subsequent 12 months. Other potential predictors of disruption were examined, including the child's age, gender, and ethnicity, the foster parent's ethnicity, the number of other children in the foster home, and the type of placement (kin or non-kin). RESULTS: Foster/kin parents reported an average of 5.77 child problems per day on the PDR checklist. The number of problem behaviors was linearly related to the child's risk of placement disruption during the subsequent year. The threshold for the number of problem behaviors per day that foster and kinship parents tolerated without increased risk of placement disruption for these latency-aged children was 6 or fewer. Children in non-kin placements were more likely to disrupt than those in kinship placements. There was a trend for increased risk of disruption as the number of children in the home increased. CONCLUSIONS: The PDR Checklist may be useful in predicting which placements are at most risk of future disruption, allowing for targeted services and supports.

The role of behavior observation in measurement systems for randomized prevention trials.

The role of behavior observation in theory-driven prevention intervention trials is examined. A model is presented to guide choice of strategies for the measurement of five core elements in theoretically informed, randomized prevention trials: (1) training intervention agents, (2) delivery of key intervention conditions by intervention agents, (3) responses of clients to intervention conditions, (4) short-term risk reduction in targeted client behaviors, and (5) long-term change in client adjustment. It is argued that the social processes typically thought to mediate interventionist training (Element 1) and the efficacy of psychosocial interventions (Elements 2 and 3) may be powerfully captured by behavior observation. It is also argued that behavior observation has advantages in the measurement of short-term change (Element 4) engendered by intervention, including sensitivity to behavior change and blinding to intervention status.

Modeling heterogeneity in social interaction processes using multilevel survival analysis.

More than 15 years ago, survival or hazard regression analyses were introduced to psychology (W. Gardner & W. A. Griffin, 1989; W. A. Griffin & W. Gardner, 1989) as powerful methodological tools for studying real time social interaction processes among dyads. Almost no additional published applications have appeared, although such data are commonly collected and the applicable questions are central to many important theoretical perspectives. To revisit the basic methods, the authors use an example from emotion regulation theory in which the level of child antisocial behavior is hypothesized to be positively associated with the hazard rate of angry emotions and negatively associated with sad, fearful emotions in the face of parental negative behavior (scolding). The authors discuss the limitations of traditional approaches to the analysis of social interaction and demonstrate improvements in the ability to model individual differences now available in existing software.

Alcohol use in motion pictures and its relation with early-onset teen drinking.

OBJECTIVE: Little is known about the impact of viewing depictions of alcohol in entertainment media on adolescent drinking behavior. Our aims were to assess drinking in a sample of popular contemporary movies and to examine the association of movie alcohol exposure with early-onset drinking in an adolescent sample. METHOD: We conducted a school-based cross-sectional survey (N=4655) with longitudinal follow-up of never-drinkers (N=2406) involving adolescents ages 10-14 years and recruited from 15 New Hampshire and Vermont schools. Screen depictions of alcohol use were timed for each of 601 popular contemporary movies. Each adolescent was asked if he/she had seen a unique list of 50 movie titles, randomly selected from the larger pool. Movie alcohol use was summed for movies the adolescent had seen, adjusted to reflect exposure to the larger pool and modeled as a continuous variable. RESULTS: Ninety-two percent of the movies in the sample depicted drinking; median screen time for movie alcohol use was 2.5 minutes (interquartile range [IQR]: 0.9-5.0 minutes). Median exposure to movie alcohol use from the 601 movies was 8.6 hours (IQR: 4.6-13.5 hours). Overall 23.1% of the cross-sectional sample had tried alcohol, and 14.8% of initial nondrinkers had tried alcohol at the follow-up assessment. We found statistical evidence to support a curvilinear association between higher exposure to movie alcohol use and increased risk of prevalent and incident alcohol use, with a statistically significant linear and quadratic effect, and suggesting a higher dose-effect relationship at lower movie alcohol exposure levels compared to higher levels. The linear and the quadratic associations remained strong and significant in cross-sectional and prospective models after controlling for sociodemographics (grade in school, school, gender, parent education), personality characteristics of the adolescent (sensation seeking, rebelliousness, self-esteem), school performance, parenting style, and smoking experimentation, suggesting that exposure to movie alcohol use is an independent risk factor for early-onset alcohol use. CONCLUSIONS: This study provides the first evidence for an association between exposure to movie alcohol use and early-onset teen drinking. The association is moderate in effect size and independent of a number of potential confounders. Because exposure to movie alcohol use is common, it may have important population implications as a potentially modifiable risk factor.

Deviancy training and association with deviant peers in young children: ocurrence and contribution to early-onset conduct problems.

The relationships of deviant talk and role taking during peer interaction, association with deviant peers, and growth in overt and covert conduct problems during kindergarten and first grade were examined in a community sample of 267 boys and girls. At entry to kindergarten, high levels of overt and covert conduct problems predicted association with deviant peers, and deviant peer association predicted deviant talk and role taking during peer interaction during kindergarten. Association with deviant peers, and deviant talk and role taking predicted growth in overt and covert conduct problems on the playground, in the classroom, and at home during kindergarten and first grade. Peer processes associated with growth in conduct problems that escalate rapidly during late childhood and adolescence appear to occur in earlier childhood. These peer processes may play a central role in the evolution of conduct problems to include covert as well as overt forms.

The course of depressive symptoms in men from early adolescence to young adulthood: identifying latent trajectories and early predictors.

Heterogeneity in the longitudinal course of depressive symptoms was studied through the use of general growth mixture modeling for young men in the Oregon Youth Study (N=206), who ranged in age from 15 to 24 years. Four trajectory classes were identified: the very-low, the moderate-decreasing, the high-decreasing, and the high-persistent classes. The 3 lowest classes differed primarily quantitatively with the initial level or mean level across time being the major determinant of class differences, whereas the high-persistent class appeared qualitatively different in terms of long-term developmental trends and variation. Findings from univariate and multivariate analyses revealed specific effects of childhood, parental, contextual, and individual risk factors on the class membership as well as on the growth within each trajectory class.

Child impulsiveness-inattention, early peer experiences, and the development of early onset conduct problems.

The conjoint influence of child impulsiveness-inattention (I/I) and peer relationships on growth trajectories of conduct problems was assessed in a community sample of 267 boys and girls. I/I reliably predicted teacher- and parent-reported conduct problems at kindergarten entry and growth in those problems over the next 2 years for boys and girls. The relation of boys' I/I to conduct problems was mediated, in part, by peer rejection and involvement in coercive exchanges with peers. The relation of girls' I/I to conduct problems was less clearly mediated by peer processes, but peer difficulties had additive effects. The impact of peer relationships on trajectories of conduct problems was apparent to parents as well as to teachers. Although I/I increments risk for early and persisting conduct problems in concert with poor peer relationships, it does so in complex and gender-specific ways.

Rigidity in parent-child interactions and the development of externalizing and internalizing behavior in early childhood.

Behavioral rigidity is a common feature of many psychopathologies, yet the association between rigidity and the development of childhood psychopathology has not been studied. State space grids (a dynamic systems [DS] method) were used to examine the relation between rigidity in parent-child interactions and childhood externalizing and internalizing problems. High-risk kindergarten children (n = 240) and their parents were observed for 2 hr engaging in a variety of tasks that were expected to elicit a range of affect. State space grid analysis of the observational data revealed an association between rigidity in parent-child interactions and child externalizing behavior problems in the fall and spring of kindergarten and 1st grade, and with growth in those problems over time. Rigidity was associated with concurrent levels and with chronic high-level internalizing problems. Strengths and limitations of the new DS methodology in relation to understanding child psychopathology are discussed.

Depressive symptoms across adolescence and young adulthood in men: predictions from parental and contextual risk factors.

The current study examined the course of depressive symptoms of young men from early adolescence through young adulthood using a growth model approach and the influence of early parental (i.e.,depressive symptoms, antisocial behaviors, substance use) and contextual (i.e., family income and parental marital transitions) risk factors on both the level of depressive symptoms in early adolescence and on changes over a 10-year period, controlling for young men's early antisocial behavior. On average, depressive symptoms of the youths tended to decrease slightly as they reached young adulthood. Among the parental and contextual risk factors, parent's marital transitions was the most significant predictor for the level of depressive symptoms in early adolescence. Parent's marital transitions and family income were also significantly related to changes in depressive symptoms. As hypothesized, there was a significant interaction effect of paternal and maternal depressive symptoms on depressive symptoms in early adolescence and on changes over time. Maternal depressive symptoms were related to the son's depressive symptoms only when the father's depressive symptoms were also high. The results also suggested that parenting practices did not mediate the effects of the parental and contextual risk factors on the development of depressive symptoms among young men.

Heterosexual risk behaviors in at-risk young men from early adolescence to young adulthood: prevalence, prediction, and association with STD contraction.

Health-compromising lifestyles involve stable patterns of behavior and are associated with high-risk social environments and accelerated developmental trajectories. Developmentally, antisocial behavior is associated with such lifestyles. Mediational models predicting a measure of lifetime average sexual risk behavior assessed over a 10-year period (from ages 13-14 to 22-23 years) were examined for a sample of at-risk young men. The measure included years of abstinence from intercourse as well as levels of 3 key heterosexual indicators of risk: frequency of intercourse, number of intercourse partners, and condom use. Predictors included lifetime average measures of contextual, family, and peer process variables and individual behaviors. In addition, similar models for prediction of STD contraction were assessed. A younger age of onset of intercourse was associated with higher numbers of intercourse partners after onset. As hypothesized, findings indicated mediational associations of socioeconomic status, parental monitoring, deviant-peer association, antisocial behavior, and substance use in the prediction of sexual risk behavior. Lower condom use also predicted STD contraction.

The role of self-control in early escalation of substance use: a time-varying analysis.

This research tested predictions about the role of temperament and self-control in early substance use (tobacco, alcohol, and marijuana). A sample of 1,526 participants was assessed in 6th grade (mean age = 11.5 years) and followed with yearly assessments through 9th grade. Latent growth models showed temperament dimensions were related to early substance use, and their effects were mediated through generalized self-control ability. Time-varying effects indicated rate of growth in substance use was higher among participants who showed increases in poor self-control and lower among participants who showed increases in good self-control. Results in self-report data were corroborated by independent teacher ratings. Findings are discussed with reference to epigenetic models of protection and vulnerability.

Observed peer victimization during early elementary school: continuity, growth, and relation to risk for child antisocial and depressive behavior.

The rate at which 266 boys and girls ages 5 to 7 years old were victimized by peers was observed on multiple occasions in kindergarten and first grade. Individual differences in victimization were observed at kindergarten entry and in growth over the subsequent 2 years. Victimization increased for some children but decreased for others. Growth in victimization was reciprocally related to growth in teacher-reported antisocial and depressive behavior for boys. For girls, kindergarten victimization was related to growth in parent-reported antisocial behavior, teacher-reported depressive behavior to growth in victimization, and growth in victimization to parent-reported depression. At a short-term group level, antisocial behavior had a lagged suppressive effect on victimization for boys but a facilitating effect for girls.
