Abstract
Purpose: Group acceptance and commitment therapy (G-ACT) was conducted involving 9 psychiatric day care patients (3 in each group), and its effect on personal recovery was examined.
Methods: G-ACT was implemented with four program sessions and two follow-up sessions. We hypothesized that G-ACT would promote personal recovery and examined the effects of individualized intervention using a single case design. As effect indicators, the frequency of occurrence of value-based actions and Questionnaire about the Process of Recovery (QPR) were used.
Results: A significant increase in the frequency of occurrence of value-based actions was observed in 5 out of the 9 patients (Tau = 0.44–0.57, p < .05). With regard to QPR, a significant increase in the score was observed in 6 out of the 9 patients (Tau = 0.55–0.75, p < .05). Three patients who did not show a significant difference in the QPR score did not exhibit a significant increase regarding value-based actions with a small effect size (Tau = 0.15–0.17).
Conclusion: Five patients whose frequency of occurrence of value-based actions increased by G-ACT also showed an increase in the QPR score, indicating that G-ACT promotes personal recovery. In the future, it will be necessary to analyze situational factors of subjects with small effect sizes and further examine methods of intervention.
