Validation of Psychological Need Satisfaction in Exercise Scale and the Behavioural Regulation in Sport Questionnaire to the Spanish context

The objective of this paper was to adapt and to validate to the Spanish sport context the Psychological Need Satisfaction in Exercise Scale (PNSE) and the Behavioural Regulation in Sport Questionnaire (BRSQ). The sample was 298 Spanish sportspersons, with a mean of 14 years old. Confirmatory Factor Analysis (CFA), internal consistency and correlation analysis were made. The respective CFAs showed that PNSE (X-2 = 222.62, p = .00, X-2/g.l. = 129, CFI = .91, IFI = .92, TLI = .91, RMSEA = .04, SRMR = .08) and BRSQ (X-2 = 824.56, p = .00, X-2/g.l. = 558, CFI = .92, IFI = .91, TLI = .92, RMSEA = .04, SRMR = .06) had good values. In the same way, the internal consistency of the respective dimensions was greater than .70. It was observed a positive and significant correlation between the three basic psychological needs, and between these ones and intrinsic motivation ( to knowledge, achievement and stimulation), the integrated regulation and identified motivation. On the other hand, the necessity of competency correlated negatively and significantly with demotivation, while the necessity of relationship with others correlated with demotivation, introjected regulation and external regulation. This work has showed two valid and reliable scales for evaluating the satisfaction with the basic psychological needs and the motivation of practitioners of physical and sport activity.
