Abstract Background Premenstrual disorders (PMDs) significantly affect women’s daily lives. This study evaluated the reliability and validity of the Mongolian-translated Premenstrual Symptoms Questionnaire (PSQ) among female nursing students at the Mongolian National University of Medical Sciences. Methods This cross-sectional study was conducted from October 2022 to January 2023. The PSQ was translated into Mongolian and its reliability and validity were assessed. A total of 431 participants completed the PSQ along with the Premenstrual Dysphoric Disorder (PMDD) Scale, Somatic Symptom Scale (SSS-8), Patient Health Questionnaire (PHQ-9), and Beck Anxiety Inventory (BAI). The reliability was evaluated using Cronbach's alpha for internal consistency. The validity was assessed using factor analysis and correlations with external measures. Results The internal consistency of the Mongolian PSQ is 0. 945. Factor analysis supported the tool’s construct validity, revealing a one-factor structure consistent with that of the original Japanese PSQ. The PSQ showed strong positive correlations with the PMDD Scale (r = 0.760), SSS-8 (r = 0.640), PHQ-9 (r = 0.580), and BAI (r = 0.620), indicating good convergent validity. Conclusion The Mongolian-translated PSQ is a reliable and valid tool for assessing premenstrual symptoms in female nursing students. These findings suggest that the PSQ is a useful tool for screening for PMDs in this population.
