Purpose The purpose of this paper is to determine the effectiveness of an adapted compassion-focused therapy (CFT) group treatment programme for individuals with an intellectual disability (ID), specifically aimed to help address maladaptive conceptualisations of masculinity. Design/methodology/approach Outcome measurements were competed at pre- and post-group and the effectiveness of the intervention were assessed using a Wilcoxon signed ranks test. Findings Findings demonstrated that the treatment group showed significant differences in their “gender role conflict” subscales including the Success, Power, Control and “Restrictive Affectionate Behavior Between Men” subscales; however, no significant differences were found on the Restrictive Emotionality or Conflicts Between Work and Leisure subscales. Furthermore, no significant differences were found on participants psychological well-being, psychological distress, anxiety, self-compassion or quality of life measures. Research limitations/implications Limitations include that a lack of qualitative information regarding outcomes, a lack of control group and a small number of participants may have impacted the outcome of the research. Practical implications The Men’s Masculinity group had a positive impact on the participant’s sense of success, power and control, so it could be considered that this group enabled participants to feel more powerful and in control of their difficulties which is associated with the “drive” system of CFT. Originality/value Overall, this study adds to the small but growing literature that supports using CFT groups as a stand-alone psychological intervention when working with people with an ID.
