The study participants in experimentalgroup received a positive psychotherapy program (n=28) and the participants in control group received only the usual treatment in communitycenters (n=29). The positive psychotherapy program was provided for 5 weeks (of 10 sessions, held twice/week, for 60 minutes). The study outcomesincluded positive affect, interpersonal relations, resilience, and mental health recovery. The collected data were analyzed using repeatedmeasures ANOVA for examining study hypothesis. Results: Results showed that interpersonal relations (F=11.83, p=.001) and resilience (F=9.62,p=.003) significantly increased in the experimental group compared to the control group. Although experimental group showed a slight increasein positive affect, it was not significant.
