Hope for all? Investigating the moderating effect of social inhibition on the association between hope and outcome in an integrative group therapy program

Existing research supports the therapeutic value of hope in different therapies and for diverse patient groups. Patients who are socially inhibited tend to have a particularly difficult time in group therapy, and the experience of hope in that context may be especially poignant for them. The present study investigated the impact of hope on the outcome of a group-based treatment and whether this impact differed for patients depending on their level of social inhibition. The sample consisted of 49 consecutively admitted patients who completed treatment in an intensive, integrative group therapy program. Patients completed four self-report measures to assess hope, social inhibition, quality of life, and depression. Regression with moderation analysis was employed. The analyses revealed that social inhibition significantly moderated the impact of hope on treatment outcome, indicating that hope had a more pronounced effect among those patients with relatively higher levels of social inhibition.
