Investigation of the effectiveness and social validity of the Triple P Positive Parenting Program in Japanese society

Abstract

A pilot trial provided some evidence that the Triple P Positive Parenting Program is effective with and acceptable to a Japanese population in Australia (Matsumoto, Sofronoff, & Sanders, 2007). This effectiveness study aimed to address theoretical and practical concerns related to the parent training program in community settings in Japan. The research used community resources within an ecological framework. Fifty-four Japanese families living in a Tokyo metropolitan area were randomly assigned to either a treatment or a wait-list control group. Program effects and acceptability were examined and then compared with the outcomes from the trial with Japanese parents living in Australia. The results showed significant program effects and high levels of acceptability of the program and core parenting skills, which was consistent with the pilot trial. The findings provided support for the effectiveness and sociocultural validation of Triple P in Japanese society. Intervention effects and program acceptability as well as limitations and future research are discussed.
