Character strength-focused positive psychotherapy on acute psychiatric wards: A feasibility and acceptability study

A manualized single-session positive psychotherapy intervention was developed and tested on acute psychiatric wards. 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. Participants (N=70) 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 mean±SD helpfulness rating (N=23) was 8.5±1.5 (on a 10-point Likert scale), and positive mood significantly increased postsession (5.9 presession vs. 7.2 postsession). Positive psychotherapy is feasible in challenging inpatient settings, and service users with severe and complex mental health conditions find it helpful.
