Evaluation of the Psychometric Properties for a Turkish Version of the Conformity to Masculine Norms Inventory-30.

Although many forms of the Conformity to Masculine Norms Inventory (CMNI) are widely used in international literature, there is yet to be a Turkish version. The CMNI-30 is an instrument consisting of 30 statements developed to measure masculinity ideologies, with statements representing different behaviors associated with masculinity. The CMNI-30 has proven reliable and valid across different languages and cultures. This study evaluated the psychometric properties of the Turkish version of the CMNI-30. Tested with 1,091 Turkish men, data were collected after content validation with the 10-factor model of the CMNI-30, indicating good construct validity. Also, convergent validity, Cronbach's alpha coefficient, item-total score analysis, and test-retest analyses were applied. Confirmatory factor analysis showed that the CMNI-30 was similar to its original structure, and all factor loadings were above 0.30. The fit indices were >0.85, and the root mean square error of approximation value was <0.05. Cronbach's alpha value was calculated as 0.871. Item-total correlations ranged between .253 and .541, and the test-retest correlation was found to be r = .344 (p < .001). Convergent validity analysis showed a significant positive relationship between CMNI-30 and Male Role Norms Scale. These findings provide preliminary evidence for the validity and reliability of the Turkish version of the CMNI-30.
