Reliability and Validity of the Chinese Version of the Premenstrual Symptoms Screening Tool

OBJECTIVE: To evaluate the reliability and validity of the Chinese version of the Premenstrual Symptoms Screening Tool (PSST) in a sample of Chinese female college students. METHODS: A total of 1366 female college students completed the Chinese version of the PSST, the Patient Health Questionnaire (PHQ), and the Generalized Anxiety Disorder Scale (GAD). According to the screening criteria of the PSST, 196 participants were categorized into the premenstrual syndrome (PMS) group, 24 participants were categorized into the premenstrual dysphoric disorder (PMDD) group, and the remaining 1146 were assigned to the healthy control group. For test-retest reliability assessment, a separate sample of 50 female college students completed the Chinese PSST twice, with a retest interval of 28-32 days (M = 30.27, SD = 0.55). RESULTS: /df = 4.21, GFI = 0.932, CFI = 0.925, TLI = 0.905, RMSEA = 0.05), indicating good construct validity. CONCLUSION: The Chinese version of the PSST exhibits excellent reliability and validity among Chinese female college students and thus serves as a reliable tool for screening moderate-to-severe PMS in this population.
