A Quasi-Randomized Trial of a School-Wide Universal Prevention Program: Results and Lessons Learned

Prevention in School (PS) is a comprehensive program which aims to improve the learning climate and reduce problem behavior in elementary schools. Core components are teaching of school rules, praise and rewards to support prosocial behavior, and a forum involving parents. This trial investigated the effects of PS on its intended outcomes, and includes 23 schools, 3,207 students, and 188 teachers. Multilevel regression analyses indicated no program effects two years after the start of the program. Problems with program components, implementation and study limitations may have contributed to the null findings. The lessons learned may be used to guide program revisions, and are important to consider in future attempts to implement and evaluate similar school interventions in a Swedish context.

Family favoritism: Defining a communication-oriented construct

This study draws from 98 participant interviews to develop an empirical definition of family favoritism. Results indicate that study participants understand favoritism as a consistent, sometimes situational parental demonstration of preferential treatment toward a particular child, especially in consideration of attention, resources, and affection. Considering a communication as constitutive of reality perspective in conjunction with the definition helps to illuminate the communicative nature of favoritism, especially as participants recognize how attention and affection are communicated and resources are offered. The results of this study suggest that communication is constitutive of favoritism, and further studies should consider communication’s centrality in familial favoritism.
