Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a complex and multifactorial chronic male disease. Although non pharmacological therapy has been widely recommended in the management of CP/CPPS, the focus is mainly on physical therapy, and discussions on psychological intervention are relatively limited. Therefore, this study aims to systematically evaluate the relevant research on CP/CPPS patients psychological intervention, in order to clarify its application scope and therapeutic effect. Through advanced searches in 5 databases, a total of 513 relevant literature from the past over 10 years were obtained, including randomized controlled trials, cohort studies, outcome measurement studies, and case series studies. The results indicate that psychological intervention has a positive effect on the CP/CPPS population. However, all included studies have a high risk of bias, which limits the generalizability and reliability of the research results. Although the current evidence is still in the preliminary stage, psychotherapy has shown certain efficacy in the combination or standalone treatment of CP/CPPS. Future research needs to develop more rigorous research methods to more effectively evaluate the effects of psychological interventions on patients with CP/CPPS.
