ABSTRACT

There is a growing number of studies evaluating the impact of positive psychology interventions (PPI’s) in people with severe mental illnesses (SMI). The results of these studies have not been quantitatively reviewed yet. In this study, we conduct a meta-analysis on the effects of PPI’s on mental health in people with SMI across studies. Sixteen studies are included (nine RCTs), representing 729 patients. Meta-analyses were performed for well-being as the primary outcome at post-treatment. We found no significant effects on both well-being en psychopathology for the PPI’s in comparison with the control conditions. Within-group effects revealed a moderate effect (Hedge’s g = 0.40) on well-being and a large effect on psychopathology (g = 0.70). Though there is at present no evidence that PPIs are more effective in comparison with other active interventions, our findings demonstrated that people with SMI do benefit from PPIs in terms of enhancement of mental health.

摘要

越来越多的研究评估积极心理干预（PPI）对严重精神疾病（SMI）的影响。这些研究的结果尚未进行定量审查。在这项研究中，我们对所有研究中PPI对SMI患者心理健康的影响进行了荟萃分析。包括16个研究（9个RCT），代表729例患者。进行荟萃分析以作为治疗后的主要结局。与对照条件相比，我们发现这对PPI的健康和精神病理学都没有显着影响。组内影响显示 对幸福感有中等影响（Hedge's g = 0.40），对心理病理学有很大影响（g = 0.70）。尽管目前尚无证据表明PPI与其他积极干预措施相比更为有效，但我们的研究结果表明，SMI患者确实在改善精神健康方面受益于PPI。
