Four different sources for cascade effects were examined using 9-year process and outcome data from a randomized controlled trial of a preventive intervention using the Parent Management Training—Oregon Model (PMTO™). The social interaction learning model of child antisocial behavior serves as one basis for predicting change. A second source addresses the issue of comorbid relationships among clinical diagnoses. The third source, collateral changes, describes events in which changes in one family member correlate with changes in another. The fourth component is based on the long-term effects of reducing coercion and increasing positive interpersonal processes within the family. New findings from the 9-year follow-up show that mothers experienced benefits as measured by standard of living (i.e., income, occupation, education, and financial stress) and frequency of police arrests. It is assumed that PMTO reduces the level of coercion, which sets the stage for a massive increase in positive social interaction. In effect, PMTO alters the family environment and thereby opens doors to healthy new social environments.

The current multigenerational study evaluates the utility of the interactionist model of socioeconomic influence on human development (IMSI) in explaining problem behaviors across generations. The IMSI proposes that the association between socioeconomic status (SES) and human development involves a dynamic interplay that includes both social causation (SES influences human development) and social selection (individual characteristics affect SES). As part of the developmental cascade proposed by the IMSI, the findings from this investigation showed that Generation 1 (G1) adolescent problem behavior predicted later G1 SES, family stress, and parental emotional investments, as well as the next generation of children's problem behavior. These results are consistent with a social selection view. Consistent with the social causation perspective, we found a significant relation between G1 SES and family stress, and in turn, family stress predicted Generation 2 (G2) problem behavior. Finally, G1 adult SES predicted both material and emotional investments in the G2 child. In turn, emotional investments predicted G2 problem behavior, as did material investments. Some of the predicted pathways varied by G1 parent gender. The results are consistent with the view that processes of both social selection and social causation account for the association between SES and human development.

This research examined personal-accentuation and contextual-amplification models of pubertal timing, wherein personal and contextual risks magnify the effects of earlier pubertal maturation on youth depression. A sample of 167 youths (M age = 12.41 years, SD = 1.19) and their maternal caregivers completed semistructured interviews and questionnaires at two waves. Consistent with a personal-accentuation model, earlier pubertal maturation more strongly predicted subsequent depression in youths with prior depression, certain personality traits, and maladaptive stress responses than in youths without these personal risks. Several of these effects were specific to earlier-maturing girls. Consistent with a contextual-amplification model, earlier pubertal maturation more strongly predicted subsequent depression in youths exposed to recent maternal depression and family stress than in youths without these contextual risks. These findings identify key characteristics of youths and their family context that help to explain individual variation in depressive reactions to earlier pubertal maturation. More broadly, this research contributes to integrative models of depression that consider the interplay among personal vulnerability, contextual risk, and developmental transitions.

Because many serious adolescent offenders reduce their antisocial behavior after court involvement, understanding the patterns and mechanisms of the process of desistance from criminal activity is essential for developing effective interventions and legal policy. This study examined patterns of self-reported antisocial behavior over a 3-year period after court involvement in a sample of 1,119 serious male adolescent offenders. Using growth mixture models, and incorporating time at risk for offending in the community, we identified five trajectory groups, including a “persister” group (8.7% of the sample) and a “desister” group (14.6% of the sample). Case characteristics (age, ethnicity, antisocial history, deviant peers, a criminal father, substance use, psychosocial maturity) differentiated the five trajectory groups well, but did not effectively differentiate the persisting from desisting group. We show that even the most serious adolescent offenders report relatively low levels of antisocial activity after court involvement, but that distinguishing effectively between high-frequency offenders who desist and those who persist requires further consideration of potentially important dynamic factors related to this process.

The aim of the present study was to assess and understand the long-term trajectory of psychological problems among young Middle Eastern refugees in Denmark. Participants were 131 young refugees from the Middle East (76 girls, 55 boys; mean age = 15.3 years) from 67 families. They were assessed first on arrival in Denmark in 1992–1993 and again 8–9 years later. The high prevalence of psychological problems at arrival was considerably reduced by the time of follow-up, but it was still somewhat higher than what has been found in most community studies using the same assessment tools. Groups of children differed in showing low levels of symptoms at arrival that were stable (spared) or increased (reacting) and high levels at arrival that persisted (traumatized) or decreased (adapted). The number of types of traumatic experiences before arrival distinguished the spared and the traumatized young refugees and the number of types of stressful events after arrival the adapted and the traumatized, also after corrections for age, sex, specific traumatic events, parents' education and health, and the social situation of the young refugees. The study emphasizes the importance of environmental factors for healthy long-term adaptation after traumatic experiences related to war and other organized violence.
