Abstract:
Collaborative Problem Solving (CPS) is an intervention for reducing children's challenging behaviors. The aim of the present study was to evaluate the effects of family therapy using CPS in an outpatient clinic that specializes in treating children with challenging behaviors. One hundred and twenty families presented for treatment. Diagnoses at intake were varied, and 100 children (83%) had symptoms that were in the clinical range at intake. Parents reported significant change in their understanding of challenging behavior and prediction of children's behavioral symptoms 3 months into treatment. Furthermore, children's improvement was predicted by their parents' increased understanding that cognitive skill deficits are responsible for challenging behavior. These results suggest that using CPS in community-based, outpatient family treatment is effective for helping children who exhibit a range of clinical symptoms. Results provide insights for clinical practice and research on CPS.

E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
