ABSTRACT:
To further evaluate the predictive validity of the Commitment to Physical Activity (CPA) scale, the relationship of the attitude of commitment to quantitative and qualitative indices of physical activity participation was investigated. Two samples of university students (n1=313; n2=146) enrolled in a physical education skills program completed the CPA scale, other questionnaires, and physical activity logs over a two-week period. Behavioral indices included total time and combinations of frequency, intensity and duration of activities. Internal consistency reliability estimates for samples one and two for the CPA scale were .91 and .85, respectively, with corrected item-to-total correlations ranging from .51 to .76 and from .40 to .71. Correlational analyses indicated that high commitment was related to greater frequency and duration of high intensity activities. The behavioral indices were regressed on a number of attitude variables including commitment, expectancy, and competitive orientation. CPA scores were found to be significant predictors of behavior, although unstable across samples. It was concluded that the attitude of commitment is predictive of physical activity involvement although other variables need to be considered when evaluating the strength of observed relationships. Evaluates the predictive potential of one attitudinal construct - commitment - as it pertains to involvement in physical activity: i.e., further evaluates the predictive validity of the Commitment to Physical Activity (CPA) scale. Also explores the predictive power of commitment to physical activity when combined with additional cognitive constructs such as perceived ability, self-efficacy, and competitive orientation. Two samples of university students (n=313 and 146) enrolled in a physical education skills program a) complete the CPA, Sport Orientation Questionnaire, and Trait Sport Confidence Inventory, b) rate their perceived ability and self-efficacy, and c) keep physical activity logs for two weeks. Finds that attitudinal commitment to physical activity is related to behavioural indices of commitment to physical anxiety. Concludes that commitment is predictive of physical activity involvement, although other variables should be considered when evaluating the strength of observed relationships.
