The psychometric properties of the Spanish version of the Sport Climate Questionnaire (S-SCQ) (SDT, Sport Climate Questionnaire, n.d.) were determined from a sample of 301 Spanish high-level competitive athletes (171 men and 130 women) from the Community of Valencia. The S-SCQ assesses athletes' perceptions of coach-provided autonomy support. The assumed uni-dimensional structure of both the long and short versions of the instrument was supported. Both versions also exhibited high reliability (internal consistency). Support for the convergent validity of the scale(s) was also obtained as the measure of coach autonomy support significantly related to the different types of motivation regulations (as assessed via the Sport Motivation Scale; Pelletier et al., 1995), in accordance with theoretical predictions.
