Abstract

Purpose: The present study aimed to determine the fit of the structural model for predicting premenstrual syndrome symptoms based on health locus of control and brain/behavioral systems mediated by physical activity.
Methods: This was a descriptive, correlational study. The statistical population of this study consisted of all married women at Rafsanjan Azad University in the fall of 2024, from which 270 people were selected using the convenience sampling method. The research instruments included the Measurement of Premenstrual Syndrome Scale, Health-Promoting Lifestyle Profile, Multidimensional Health Locus of Control Scale, and Behavioral Activation and Behavioral Inhibition Systems Scale. Structural equation modeling was used to analyze the data.
Results: The results showed that PMS symptoms are predicted based on external health locus of control (P=0.005, β=0.116), internal health locus of control (P=0.001, β=-0.144), behavioral inhibitory system (P=0.008, β=0.109), behavioral activating system (P=0.003, β=-0.124) with the mediation of physical activity in married women at the 0.01 level.
Conclusion: Designing and evaluating educational or therapeutic programs according to biological and brain/behavioral characteristics to change the locus of control from external to internal and assess its effects on reducing PMS symptoms, along with physical activity, is suggested as a strategy for managing and reducing PMS symptoms.
