One plausible application would be to the antisocial behaviors of sex offenders, since common clinical offense cycle models appear to imply nonlinearity. In this article, we fit linear and nonlinear models to three time series of antisocial behaviors of three adolescent sex offenders. Nonlinear models best characterize two of the three time series. The implications of nonlinearity in offender behaviors include difficulty in demonstrating the effectiveness of interventions, the possibility of endogenously generated swings in behavior, and the possibility that attempts to control offending behaviors might actually lead to larger numbers of those behaviors.

This article examines the Family/Visitor Survey (FVS), a brief instrument designed to measure family/friend involvement at Ohio's Behavioral Health Organizations (BHO), the state system of psychiatric hospitals.

Nonlinearity in the relationship between group aggression and individual aggression at 2-year follow-up is present. Consistent with the findings of Kellam et al. (1998), hierarchical linear modeling indicates that the relationship is statistically significant for those students whose initial parental ratings of aggressive behavior were above the sample median. In the context of competition between students, the behavior of initially aggressive students may be negatively reinforced. Lowering aggression in the school environment may therefore be the most effective way to lower the level of these students’ aggressive behavior.
