Abstract
In this study, the validity and reliability of Empowering and Disempowering Motivational Climate Questionnaire (EDMCQ-C) which measures the motivational climate created by the coach based on a multi-dimensional and hierarchical model were tested. The research consists of two separate studies. In the first study, the construct validity of the scale was examined by Exploratory Factor Analysis and convergent validty. Cronbach’s Alpha internal consistency coefficient was calculated to test reliability. In the second study, the five-factor and two-factor structure of the scale were examined at the first order confirmatory factor analysis; while the five-sub factors with two-upper factor structure were examined at the second order confirmatory factor analysis. Average Variance Extracted (AVE), Maximum Shared Variance (MSV), Average Shared Variance (ASV) and Composite Reliability (CR) values were calculated for the scale's convergent-divergent validity and reliability. One hundred eighty girls (Mage=14.97; Sd=1.75), 180 boys (Mage=15.02; Sd=1.85), 360 adolescent (Mage=15.00; Sd=1.80) athletes voluntarily participated in the first study and 113 girls (Mage=15.32; Sd=1.46) and 183 boys (Mage=15.67; Sd=1.59), totally 296 adolescent (Mage=15.54; Sd=1.55) athletes participated in the second study. The results of Principle Components Factor Analysis with Varimax Rotation supported the five-factor structure of the scale and the items explained 68.70% of the total variance; with the DFA performed within the scope of the second study, acceptable compliance values were achieved. The correlation between the Empowering and Disempowering Motivational Climate Questionnaire and Perceived Autonomy Support Scale supports the convergent validity of the inventory; AVE, MSV, ASV and CR values calculated within the scope of the second study also support convergent and divergent validity. While the internal consistency coefficients calculated within the scope of the first study regarding the reliability of the scale varied between .76 and .94; the internal consistency coefficients calculated within the scope of the second study took the value between .73 and .87 for the five-factor structure of the scale and .92 in both sub-dimensions the two-factor structure. CR coefficients were also calculated within the scope of the second study to determine the reliability of the scale; the CR coefficients calculated for the five-factor structure of the scale are between .79 and .87, for its two-factor structure, it is seen that it takes .93 and .92 values. The results of the study suggest that the Empowering and Disempowering Motivational Climate Questionnaire is a valid and reliable tool for the evaluation of the coach creadted motivational climate in adolescents interested in individual sports.
