The major purposes of the research were to develop and examine a solution-focused group counseling program for treating middle school students with disruptive behavior problems. Sixteen nine-grade, male students were referred and invited to participate this quasi-experimental research. A “Social-behavioral Inventory for Adolescents” was administered to all participants before and after the quasi-experiments. The experimental group was composed of eight students, who received the solution-focused group counseling program two-hour per week for eight weeks in length. The first author was the group leader, and a guidance teacher of the school acted as a participant observer throughout the group sessions. Data were collected from multiple resources, including pre-test and post-test scores of the inventory, immediate field notes taken by the observer, research dairy of the first author, transcripts from in-depth interviewing with each participant right after each session, as well as group feedback and reflection on personal changes reported by each participant after the termination of the program. Data were analyzed both quantitatively and qualitatively. The following conclusions were drawn from this study, including: (1) after having undergoing the program, participants in the experimental group demonstrated significantly high level of adaptive behaviors, and reduced significantly their maladaptive behavior problems; (2) five major themes emerged from the participants’ self-perceived personal changes, that is, promoting interpersonal interaction, enhancing positive thinking, managing negative emotion, changing behavior patterns, and expressing positive evaluation on their personal change.
