Drawing from contemporary goal perspective theories of achievement motivation, this investigation had as its primary purpose to determine the relationship of perceived motivational climate to intrinsic motivation and attributional beliefs in a sport setting. This study also examined the degree to which the dependent variables of interest are a function of situational goal structure, dispositional goal orientations, or both. Subjects, 105 male basketball players from nine varsity high school teams, were requested to complete the four instruments. Results indicated that the Perceived Motivational Climate in Sport Questionnaire was comprised of two valid and reliable subscales, the Mastery and Performance Climate scales. Perceptions of a mastery-oriented climate positively related to reported enjoyment and the belief that effort leads to achievement. Perceptions of a performance-oriented climate were associated with the view that superior ability causes success. In general, indices of intrinsic motivation and attributional beliefs were best predicted by dispositional goal orientation.
