The relationship between multidimensional perfectionism and psychological need thwarting in junior sports participants

Objectives: Perfectionism is thought to energise high quantities of motivation; however, its wider influence on the quality of the motivation exhibited by athletes is less clear. The purpose of this study was to examine the multivariate and univariate relationship between multidimensional perfectionism (perfectionistic concerns and perfectionistic striving) and perceived psychological need thwarting. Perfectionistic concerns was assessed via sub-dimensions of socially prescribed perfectionism, concern over mistakes, doubts about actions, parental pressure and coach pressure. Perfectionistic striving was assessed via sub-dimensions of self-oriented perfectionism, other-oriented perfectionism, personal standards and a need for organisation. Design: A cross-sectional, survey-based design was employed. Method: One hundred and ninety-nine junior sports participants were recruited from after-school sports clubs and completed measures of multidimensional perfectionism and psychological need thwarting. Results: Canonical correlation analyses revealed that higher levels of perfectionistic concerns were associated with higher levels of perceived psychological need thwarting. Analogously, lower levels of perfectionistic striving were associated with lower levels of perceived psychological need thwarting. Regression analyses revealed that the relative importance of individual sub-dimensions of perfectionism differed depending on the facet of psychological need thwarting being assessed. Perceptions of parental pressure, coach pressure and concern over mistakes emerged as especially important. Conclusion: Overall, the findings indicate that while perfectionism may contribute to high levels of behavioural investment, it may also impoverish the necessary support required for the fulfilment of psychological needs.
