The effects of a school-based cognitive-behavioral intervention program on the depression scores of sixth-grade students: A comparison outcome study

摘要

The effects of a school-based cognitive-behavioral intervention approach on the depression scores of sixth grade students were examined in the study. Two hundred and one sixth grade students served as participants in one of four experimental groups: treatment group, attention-placebo group, delayed treatment group, and no treatment control group. All groups, except the control group, participated in the school-based program called "learned optimism." The learned optimism program is an eight-week curriculum-based program designed to assist adolescents in developing a more optimistic self-explanatory style that contributes to resiliency and positive mental health. All participants completed the Children's Depression Inventory (CDI) on three occasions: before the learned optimism program began (pretest), immediately after the first eight-week program was terminated (posttest 1) and eight weeks later, after the second eight-week program was terminated (posttest 2/follow-up). The results were unexpected. They showed only a significant difference on CDI total scores between the treatment group and delayed treatment group immediately following both groups' participation in the learned optimism program. No significant differences on CDI total scores were found at any other time between or within any of the four groups. Some significant differences were found on CDI subscales between the treatment and delayed treatment groups, but not in the expected direction. Results from an informal questionnaire completed by participants showed that most liked the learned optimism program and it made them feel happier. Plausible explanations for the findings were discussed along with limitations of the study and recommendations for future research in this area.
