Aggressive behavior in childhood and early adolescence: an ecological-developmental perspective on youth violence.

This article reviews recent research on the development of aggressive behavior in childhood and early adolescence using an ecological perspective that focuses on social development in the family, school, peer group, and community. Special emphasis is placed on family processes and early childhood peer relations that appear to tip developmental trajectories toward social rejection at school and use of aggression to achieve social goals in interpersonal relationships. The article discusses implications for preventing youth violence.

The social networks of drug abusers before and after treatment.

Changes in the social networks of a sample of 38 drug abusers are studied from pretreatment to 1 and 3 months following treatment. Overall network composition changed to include fewer drug users and fewer long-term acquaintances. While the pretreatment networks of those who used opiates and those who did not use opiates in the follow-up period were virtually the same, the posttreatment networks of opiate abusers contained greater social influence toward drug use following treatment. Implications for treatment are discussed.

The social networks of opioid abusers.

Using social network analysis, the pretreatment social networks of 106 street drug abusers are examined. While no significant sociodemographic differences are found between opioid and nonopioid abusers, eight significant univariate differences in the characteristics of their social networks are reported. Four of these differences account for 32% of the variation between the two groups of abusers. The social networks of opioid abusers appear significantly less conventional than those of nonopioid abusers; however, opioid abusers appear less committed to the values and behaviors displayed by their network members. Network reconstruction is discussed as an explicit, empirically supportable rehabilitation strategy.

In-home family-focused reunification: an experimental study.

Intensive, in-home family-based services were employed in reunifying families separated by the placement of a child in out-of-home care. After a 90-day service period, 93% of the 57 families randomly assigned to receive the intensive treatment were reunited-compared to 28% of the 53 families in a control group who received routine out-of-home care services. Follow-up data were collected six and 12 months after the end of treatment. Estimates of outcomes suggest that the experimental treatment had a substantial impact on families and that treatment effects endured for upwards of 12 months following cessation of direct intervention services.
