Motivational Factors on Exercise Behavior in Youth

Wannee Jermsuravong




Abstract


The purpose of this study was (a) to validate the Thai version of Exercise Motivation Scale (TEMS) and (b) to assess the exercise motivational factors that determine the exercise behavior of Thai youth. The total subjects for main purpose of study were 1912 (949 males and 963 females), aged between 18 and 22 (M = 19.87, SD =1.31), who regularly exercise in the public parks, health clubs, and fitness centers throughout Thailand. All 8 subscales of TEMS (amotivation, external regulation, introjected regulation, identified regulation, integrated regulation, intrinsic motivation to learn, to accomplish the task and to experience sensation) were found to be reliable (alpha .60 to .76) and confirm factor analysis (CFA) indicated that the measurement model was fit with the data reasonably well. However, since three items (the External factor, the Introjected factor, and intrinsic motivation to accomplishment) showed unaccepted values on the multiple squared correlations, they were then removed from TEMS with better values. The second order analysis of the three factors was then examined with non fit results. An examination of the correlation matrix indicated high factor correlations among three latent factors of extrinsic motivation (Identified, Introjected, Integrated) and three latent factors of intrinsic motivation. These high correlations values were revised in Extrinsic Motivation and Intrinsic Motivation, so that, the only four factors of motivation were used for further analysis. The second order of TEMS showed good fit. The exercise motivation and exercise behavior were found to be related with statistical significance of .01.
