The research design was quasi-experimental with a pre-test and post-test on the experimental and control groups, and a two-month follow-up. After conducting a sociometric assessment, 30 students were randomly selected from 42 adolescents identified as bullies and randomly assigned to an experimental group that received Adlerian social interest training or a delayed-treatment control group. The Matson Evaluation of Social Skills with Youngsters (MESSY) and the Revised Olweus Bully/Victim Questionnaire (OBVQ-R) were administered at the pre-test stage. The experimental group received 12 weekly sessions (two sessions per week) of social interest training, and the control group was placed on the waiting list. Two-factor analyses of variance revealed that social interest training significantly increased social skills and reduced bullying behaviors of the experimental group in the post-test and follow-up stages. A discussion of the benefits of social interest training followed.en-USAdlerian social interest trainingSocial skillsBullyingAdolescentsArticle2164-45270
