Psychometric Properties and Factor Structure of Persian Version of Premenstrual Coping Measure

The present study was conducted with the aim of introducing and investigating the psychometric properties of the Persian version of the Premenstrual Coping Measure (PMCM (. This research, in terms of method, is a descriptive-cross-sectional-correlation study that its population included all the female students in Salman Farsi University of Kazeroon in the academic year of 2021-2022. The sample group included 303 female students who were selected by the available sampling method and actually participated in the present research by answering the online questionnaire. This questionnaire, in addition to the Persian version of the PMCM, included the Premenstrual Symptoms Screening Tool, Multidimensional Health Locus of Control-C, and the Menstrual Attitude Questionnaire. Research data has been analyzed in SPSS-22, AMOS-22 and JASP-09. The results of exploratory and confirmatory factor analysis have confirmed the existence of a five-factor structure in the scores obtained from the Persian version of the premenstrual coping strategies scale. The values of Cronbach’s alpha and McDonald's omega also showed good internal consistency in the total scale and its five subscales. The correlation coefficients between PMCM, and three other research tools, while confirming the construct validity, suggested a close relationship between premenstrual strategies and an internal locus control for health and an attitude based on expectation and prediction of menstruation.
