Measuring self-determination motivation in a physical fitness setting: validation of the Behavioral Regulation in Exercise Questionnaire-2 (BREQ-2) in a Spanish sample.
OBJECTIVE
The aim of this study is the validation in the Spanish context of the Behavioural Regulation in Exercise Questionnaire-2 (BREQ-2) scale, developed by Markland et al., from the point of view of the self-determination theory and to compare the effect of gender, age and exercise duration and mode.


METHODS
For the validation of the instrument, two studies were carried out (n=250 and n=311) with a total sample formed of 561 adults in the metropolitan area of the city of Murcia, Spain, who do non-competitive sport and physical activities. They were given the adaptation of the questionnaire BREQ-2 by Markland et al. to fill in.


RESULTS
After an exploratory factor analysis and a confirmatory factor analysis, an adaptation of the scale was obtained with 18 items and 5 factors with acceptable reliability coefficients and a total variance explained of 68.8%. The two highest assessed forms of behavioral regulation were intrinsic and identified, with the women showing more intrinsic regulation. Those that exercised for less time were the ones that showed higher levels of amotivation and the older people showed a greater tendency to identified regulation.


CONCLUSIONS
The BREQ-2 scale has all the required conditions, as far as reliability and validity criteria are concerned, to be used in the Spanish context in different areas of physical activity.
