Premenstrual disorders (PMDs) significantly affect the daily lives of women. 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.
This cross-sectional study was conducted from February 2023 to January 2024. The PSQ was translated into Mongolian, and its reliability and validity were assessed. A total of 431 participants completed the translated PSQ along with the Premenstrual Dysphoric Disorder (PMDD) Scale, Somatic Symptom Scale (SSS-8), Patient Health Questionnaire (PHQ-9), and Beck Anxiety Inventory (BAI). Reliability was evaluated via Cronbach's alpha for internal consistency. Validity was assessed via factor analysis and correlations with external measures.
The internal consistency of the Mongolian PSQ was 0. 945. Factor analysis supported the tool's construct validity, which revealed a one-factor structure consistent with that of the original Japanese PSQ. The PSQ had 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), which indicated good convergent validity.
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 PMDs in this population.
经前疾病（PMDs）严重影响女性的日常生活。本研究评估了蒙古国立医科大学女护理学生中蒙古语翻译版的经前症状问卷（PSQ）的信度和效度。
本横断面研究于2023年2月至2024年1月进行。将PSQ翻译成蒙古语，并评估其信度和效度。共有431名参与者完成了翻译后的PSQ以及经前烦躁障碍（PMDD）量表、躯体症状量表（SSS - 8）、患者健康问卷（PHQ - 9）和贝克焦虑量表（BAI）。通过Cronbach's alpha评估内部一致性来评价信度。通过因子分析和与外部测量的相关性来评估效度。
蒙古语PSQ的内部一致性为0.945。因子分析支持该工具的结构效度，揭示了与原始日语PSQ一致的单因素结构。PSQ与PMDD量表（r = 0.760）、SSS - 8（r = 0.640）、PHQ - 9（r = 0.580）和BAI（r = 0.620）有很强的正相关，表明具有良好的收敛效度。
蒙古语翻译版的PSQ是评估女护理学生经前症状的可靠且有效的工具。这些发现表明PSQ是该人群中筛查PMDs的有用工具。
