The scale consists of 24 items and 6 subdimension including intrinsic motivation, integrated regulation, identified regulation, introjected regulation, external regulation and motivation. Study group consists of total 681 student- athlete whom are licensed athletes and study at Physical Education and Sports College of Ahi Evran University, Erciyes University, Dumlupinar University and Çanakkale 18 Mart University. In order to determine psychometry properties of scale internal consistency, material and factor analysis and test- retest methods were applied. Cronbach alpha internal consistency coefficient of the measurement determined as follows; 0.790 for total points, 0.856 for intrinsic motivation subdimension, 0.838 for integrated regulation subdimension, 0.862 for identified regulation subdimension,
