Front. Psychol. 9:1057. doi: 10.3389/fpsyg.2018.01057http://hdl.handle.net/10347/20137The theory of self-determination establishes the existence of three basic psychological needs (autonomy, competence, and relationship). If these needs are satisfied, optimal personal well-being will be achieved. The Basic Needs Satisfactions in Sport Scale (BNSSS) is a measurement developed to evaluate these needs within the sporting context. The BNSSS measures the satisfaction of the three basic psychological needs through 20 items distributed in five dimensions: autonomy-choice, autonomy-volition, autonomy-perceived locus of internal causality, competence, and relatedness. The purpose of this study is to validate a Spanish version of the BNSSS. The sample were 441 team athletes with a mean age of 17.46 (SD = 3.59), which 46.5% were men and the remaining percentage (53.5%) were women. After a standardised data collection, confirmatory factor analysis and invariance analyses were performed, as well as composite reliability. The obtained version showed a good overall fit of the model and values of composite reliability higher to 0.70. Therefore, a useful tool for assessing basic psychological needs in team sports was obtained.engCopyright © 2018 De Francisco, Parra, Arce and Vílchez.
