The present study examined the relationship between dance-related perfectionism and perceptions of motivational climate in dance over time. In doing so, three possibilities were tested: (a) perfectionism affects perceptions of the motivational climate, (b) perceptions of the motivational climate affect perfectionism, and (c) the relationship is reciprocal. Two hundred seventy-one young dancers (M = 14.21 years old, SD = 1.96) from UK Centres for Advanced Training completed questionnaires twice, approximately 6 months apart. Cross-lagged analysis indicated that perfectionistic concerns led to increased perceptions of an ego-involving climate and decreased perceptions of a task-involving climate over time. In addition, perceptions of a task-involving climate led to increased perfectionistic strivings over time. The findings suggest that perfectionistic concerns may color perceptions of training/performing environments so that mistakes are deemed unacceptable and only superior performance is valued. They also suggest that perceptions of a task-involving climate in training/performing environments may encourage striving for excellence and perfection without promoting excessive concerns regarding their attainment.
