Effects of anger management and goal setting group interventions on state-trait anger and self-efficacy beliefs among high risk adolescents

In this study we evaluated the effects of two psychoeducational groups (anger management and goal setting) on state and trait anger, anger expression, and on self-efficacy beliefs of high risk adolescents enrolled in an alternative high school. Participants (n = 57) were pre- and post-tested using the State Trait Anger Expression Inventory (STAXI) with subscales for (a) state anger, (b) trait anger, and (c) anger expression, and on a measure of self-efficacy related to (a) anger management, (b) goal setting, and (c) group behavior and interpersonal communication. We hypothesized that each treatment would favorably impact the self-efficacy items related to it, that participants in both treatment groups would show gains in self-efficacy for general group behavior and communication skills, and that the anger management treatment would decrease state anger and anger expression. Results of a series of Repeated Measures ANOVAS revealed no group effects or group by time interaction effects. Analysis of Cohen's d effect sizes for the treatment groups in comparison with the control condition indicated only small treatment effects for the goal setting group on the STAXI, and small, negative treatment effects for the anger management group on the STAXI and on state anger. Thus, results failed to support the hypotheses with the current data set. Limitations of this study and implications for future research and group practice within schools are discussed.
