Psychological interventions for women with polycystic ovary syndrome (PCOS): a systematic review and meta-analysis of randomised and non-randomised controlled trials

Polycystic ovary syndrome (PCOS) is an endocrine condition affecting 8–13% of reproductive-aged women globally. Psychological features of PCOS are often overlooked despite their association with mental health complications. This systematic review synthesises existing evidence of psychological interventions for women with PCOS. Database searches returned 4982 articles, of which 20 papers were eligible; 12 studies were meta-analysed. Compared to control, psychological interventions had statistically beneficial effects on change from baseline values for depression, PCOS-specific quality of life, general health, and body image. Significant improvements were found in all PCOS Questionnaire (PCOSQ) domains except acne, yet the importance of these differences in clinical practice was indeterminable. Despite statistical effects, the quality of evidence was judged as low/very-low due to between study heterogeneity, risk of bias, and imprecision in effect estimates. Future studies should focus on rigorously designed, well-reported trials, in order to address the uncertainty around the effectiveness of psychological interventions. The protocol of this systematic review was prospectively registered on the International Prospective Register of Systematic Reviews (PROSPERO: CRD42023472417).
