Aim: To conduct a Turkish validity and reliability study of the "Female Muscularity Scale" that determines the attitudes and behaviors of women regarding muscularity, and to adapt it to Turkish society.
Material and Method: This study, which is of the methodological type, was conducted in September 2018 through a social media instrument. Data were collected from a total of 300 females who agreed to participate in the survey without implementing sampling methods. The data was collected via the internet by reaching the students of a large university located in the Eastern part of Turkey through social media accounts.
“Personal Information Form” and “Female Muscularity Scale”s Turkish Form” have been used in data collection. Data analyses were run with SPSS (version 18, SPSS Inc.) package program. In the study, KMO index scores, Barlett's Test of Sphericity, Factor Loadings, Cronbach’s Alpha coefficient, Item-total correlations and fit indexes have been calculated.
Findings: Female Muscularity Scale's language validity has been ensured by the translation-re-translation method, then necessary corrections have been applied based on expert suggestions and content validity has been provided. The factor analysis showed a two-factor structure and factor loadings were found to be at the appropriate range (0.47-0.85). In the internal consistency analysis of the scale, ; the Cronbach’s alpha coefficient of the 1. sub-dimension (attitudes) was found to be 0,79, 2. sub-dimension (behaviors) was found to be 0.84 and the Cronbach’s alpha coefficient for all items of the scale was found to be 0.86. Item-total correlations of the scale were found to be between 0.408 and 0.737. After the analysis was run, the rate of the chi-square statistic to degrees of freedom (χ2/df) was found to be 3.128 (χ2=185.302 df=38); Root Mean Squares Error of Approximation (RMSEA) was found to be 0.07; Tucker-Lewis Index(TLI) score was found to be 0.91, and Comparative Fit Index (CFI) score was found to be 0.90.
Conclusion: Female Muscularity Scale's Turkish version has been determined as a valid and reliable measuring instrument.
