This study investigated the economics of multisystemic therapy (MST) versus individual therapy (IT) using rearrest data from a 13.7-year follow-up (Schaeffer & Borduin, 2005) of a randomized clinical trial with serious juvenile offenders (Borduin et al., 1995). Two types of benefits of MST were evaluated: The value to taxpayers was derived from measures of criminal justice system expenses (e.g....

This article examined the long-term effects of multisystemic therapy (MST) vs. individual therapy (IT) on the prevention of criminal behavior and violent offending among 176 juvenile offenders at high risk for committing additional serious crimes. Results from multiagent, multimethod assessment batteries conducted before and after treatment showed that MST was more effective than IT in improvin...

How can collective action evolve when individuals benefit from cooperation regardless of whether they pay its participation costs? According to one influential perspective, collective action problems are common, especially when groups are large, but may be solved when individuals who have more to gain from the collective good or can produce it at low costs provide it to others as a byproduct. S...

Previous research has documented cross-sectional associations between negative and positive work-family spillover and physical health. Using an effort-recovery model, the study tested the hypothesis that engagement in greater leisure-time physical activity would facilitate recovery processes that buffer the negative health effects of increasing work-family spillover. Employed adults (N = 1,354)...

We discuss agent-based models (ABM) as research tools for developmental and social psychology. “Agents” are computer-based entities, e.g., “people.” The modeler assigns the agents real-world roles and rules, conducts simulation experiments in which the agents follow their rules, and observes real-time data. Agent-based models have some properties that can be very useful to psychology. Agent-bas...

BACKGROUND Individuals who make a living through agriculture and animal husbandry are faced with a variety of physical and psychological health risks. In many international studies, it has been shown that these risks can result in disease. The purpose of this study is to summarize the health risks faced by Turkish agricultural workers. MATERIALS AND METHODS This study used a nonrandom, conven...
