Substance abuse hinders desistance in young adults' antisocial behavior

We examined two hypotheses about the developmental relation between substance abuse and individual differences in desistance from antisocial behavior during young adulthood. The "snares" hypothesis posits that substance abuse should result in time-specific elevations in antisocial behavior relative to an individual's own developmental trajectory of antisocial behavior, whereas the "launch" hypothesis posits that substance abuse early in young adulthood slows an individual's overall pattern of crime desistance relative to the population norm during this developmental period. We conducted latent trajectory analyses to test these hypotheses using interview data about antisocial behaviors and substance abuse assessed at ages 18, 21, and 26 in men from the Dunedin Multidisciplinary Health and Development Study (N = 461). We found significant individual variability in initial levels and rates of change in antisocial behavior over time as well as support for both the snares hypothesis and the launch hypothesis as explanations for the developmental relation between substance abuse and crime desistance in young men.

Linked Lives: Stability and Change in Maternal Circumstances and Trajectories of Antisocial Behavior in Children

Drawing on the notion of linked lives, this study examined the effects of stability and change in maternal circumstance on developmental trajectories of antisocial behavior in children 4 to 7 years of age. Using data from a national sample of young mothers and growth curve analysis, the study demonstrated that early maternal circumstances influences early antisocial behavior, whereas stability and change in these circumstances both exacerbate and ameliorate behavior problems. Of particular note, meaningful escape from poverty attenuates antisocial behavior whereas persistence in poverty or long-term movement into poverty intensifies such problems. These findings highlight the importance of structural context for parenting practices and the need to consider child development in light of dynamic and changing life-course fortunes of parents.

A longitudinal–experimental approach to testing theories of antisocial behavior development

A longitudinal study with a nested preventive intervention was used to test five hypotheses generated from developmental theories of antisocial behavior. The longitudinal study followed 909 boys from their kindergarten year up to 17 years of age. The randomized multimodal preventive intervention targeted a subsample of boys who were rated disruptive by their kindergarten teacher. Semiparametric analyses of developmental trajectories for self-reported physical aggression, vandalism, and theft identified more types of trajectories than expected from recent theoretical models. Also, these trajectories did not confirm theoretical models, which suggest a general increase of antisocial behavior during adolescence. The majority of boys were on either a low-level antisocial behavior trajectory or a declining trajectory. Less than 6% appeared to follow a trajectory of chronic antisocial behavior. Comparisons between disruptive and nondisruptive kindergarten boys confirmed the hypothesis that disruptive preschool children are at higher risk of following trajectories of frequent antisocial behavior. Comparisons between treated and untreated disruptive boys confirmed that an intensive preventive intervention between 7 and 9 years of age, which included parent training and social skills training, could change the long-term developmental trajectories of physical aggression, vandalism, and theft for disruptive kindergarten boys in low socioeconomic areas. The results suggest that trajectories of violent behavior can be deflected by interventions that do not specifically target the physiological deficits that are often hypothesized to be a causal factor. The value of longitudinal-experimental studies from early childhood onward is discussed.

Protective factors related to antisocial behavior trajectories.

A group of 115 fifth- and sixth-grade Latino students were surveyed at the beginning and the end of the school year before their transition to middle or junior-high school about their engagement in antisocial behaviors and about individual, social, and behavioral protective factors. The best predictors of decreases in antisocial behavior for these students, above and beyond variance for initial ratings and gender, were student perceptions of social support, parent supervision, and classroom participation. The importance of keeping students engaged in school academic work as a protection against antisocial behavior is emphasized as well as the need to help students gain skills necessary to access support for this academic work.
