The study aimed to investigate the feasibility and acceptability of a cognitive-behavioural therapy group for domain-specific self-esteem. It also sought to evaluate the effectiveness of the intervention on global self-esteem, depression, anxiety and psychological wellbeing. The study used a pretest-posttest single group design, with a one-month follow-up. The intervention was predominantly deemed to be feasible and acceptable. Recruitment rates and post-treatment retention rates exceeded the study targets. However, retention rate at follow-up was below the study target. Significant improvements were observed in global self-esteem, depression and psychological wellbeing following the intervention. No changes were observed in anxiety. The intervention should now be evaluated further in a randomised controlled trial.
