Objective: The aim of this study was to investigate the psychometric properties of the Female Muscularity Scale (FMS).
Method: Two different samples were determined to reach the research aim. The first of these is a sample of 153 female participants doing exploratory factor analysis. The second sample consisted of 213 women exercising with confirmatory factor analysis and additional analyzes. IBM SPSS Statistics 22 and AMOS 22 software were used in the analysis of the obtained data.
Results: According to the results of Exploratory Factor Analysis, the two-factor structure was determined as attitude and behavior according to the results of exploratory factor analysis. As a result of the exploratory factor analysis conducted to test the construct validity of the inventory, 68% of the two-factor structure variance was determined. Internal consistency coefficients were calculated to test the reliability of the scale. Internal consistency coefficients obtained for 213 participants were 0.94 in the “Attitude” sub-scale and 0.92 in the “Behavior” sub-scale. The results of the Confirmatory Factor Analysis (x2 / sd (2.231) value, especially the index of fit, indicates that the model shows a good fit. The results of the confirmatory factor analysis conducted to test the construct validity of the scale showed that the indices of the scale, which consisted of two sub-scales, totaling 10 items, were acceptable.
Conclusion: In conclusion, the results of the study revealed that the 10-item FMS is a useful scale for determining the level of drive for muscularity in the Turkish sample of female participants.
