Normalization of the 8-point scale of passion in sports

The purpose of this study was to standardize the 8-item scale of passion in sports. Considering that the present study determines the reliability and validity of the passion scale in sports, the research design is in terms of the type of research development, which was analytical and correlational. The statistical population of the present study consisted of all female athletes in Baharestan city (421 people). Two hundred people were selected according to the Cochran formula. This study used the passion scale of Sigmundson et al. Confirmatory factor analysis was used to evaluate the construct validity of the questionnaires and model fit indices were used to evaluate the model. The results showed that all the indicators related to the scale of desire have a factor load higher than 0.4. Therefore, they have an acceptable factor load and t values and they are considered as appropriate indicators. Therefore, the construct validity of the passion scale is confirmed. Also, the passion scale with a variance of 0.51 and combined reliability (Dillon-Goldstein coefficient) was 0.88. Therefore, convergent validity is an approved measure of passion. In addition, Cronbach's alpha coefficient of the passion scale was 0.90, which indicates that the reliability of this scale is desirable. Therefore, the reliability of the passion scale is confirmed.
