Character Strength-Focused Positive Psychotherapy on Acute Psychiatric Wards: A Feasibility and Acceptability Study

Objective: A manualized single-session positive psychotherapy intervention was developed and tested on acute psychiatric wards. Methods: Participants were invited in 2018–2019 to identify positive experiences, link them to a personal character strength, and plan a strengths-based activity. The intervention’s feasibility was evaluated through fidelity to session components, character strengths identification, and activity completion. Acceptability was evaluated with self-reported pre- and postsession mood ratings, a postsession helpfulness rating, and narrative feedback. Results: Participants (N570) had complex and severe mental health conditions. In 18 group sessions, 89% of components were delivered with fidelity; 80% of the participants identified a character strength, of whom 71% identified a strengths-based activity, and 58% completed the activity. The mean6SD helpfulness rating (N523) was 8.561.5 (on a 10-point Likert scale), and positive mood significantly increased postsession (5.9 presession vs. 7.2 postsession). Conclusions: Positive psychotherapy is feasible in challenging inpatient settings, and service users with severe and complex mental health conditions find it helpful.
