Translation and validation of the exercise adaptation of the Perceived Motivational Climate Sport Questionnaire

The main purpose of this study is to present the results of translation and validation of the Portuguese version of Perceived Motivational Climate in Sport Questionnaire (PMCSQ) adaptation to exercise, through exploratory (EFA) and confirmatory (CFA) factor analysis, performed with two independent groups of participants, all exercisers in private fitness clubs, of both sexes, and aged between 14 and 64 years old. The EFA results reveal a structure explaining 52% of total variance, with factor loadings ranged from 0.63 to 0.80, and reasonable reliability (alpha(Mastery)=0.78; alpha(Performance)=0.74). The AFC results showed an excellent model fit to data: S-B chi(2)=40.6; df=34; p=0.20; S-B chi(2)/df=1.19; SRMR=0.03; NNFI=0.98; CFI=0.99; RMSEA=0.02; 90% IC RMSEA=0.00-0.05, an acceptable reliability (alpha(Mastery)=0.74; alpha(Performance)=0.75), and factor loadings ranged from 0.50 to 0.79, which leads us to conclude that Portuguese version of PMCSQ adaptation to exercise can be used to measure motivational climate in exercise.
