The present study examined the link between motivation profiles among adult sports participants and the consequences of enjoyment, effort, positive and negative affect, attitude toward sport participation, intention to continue sport participation, satisfaction, and frequency of attendance in sport. Two samples of participants (n = 590 and n = 555) completed the Sport Motivation Scale and a range of self-report measures to assess the outcome variables. Exploratory cluster analyses applied to Sample I and confirmatory cluster analysis applied to Sample 2 identified two clusters of sport participants. The first comprised participants with high scores on both nonself-determined and self-determined motives. The second comprised participants with high scores on self-determined motives but low scores on nonself-determined motives. Participants in the first cluster scored higher on all outcome variables. The results are discussed with reference to a more in-depth understanding of the motivation dynamics of sport participation based on Self-Determination Theory.

The present study investigated the factor structure, scale dimensionality, discriminant validity, internal consistency, simplex structure, and nomological validity of the Greek translation of the Behavioral Regulation in Exercise Questionnaire-2 (BREQ-2; Markland & Tobin, 2004 ). A total of 733 Greek exercise participants completed the translated scale to indicate their reasons for participation in structured exercise programs. Confirmatory factor analyses supported the a priori 5-factor structure with strong internal consistency for the instrument subscales. Further support was obtained for the simplex pattern as well as the nomological correlations of the translated BREQ-2 responses with self-determination theory variables. Overall, the results provided initial support for the psychometric value of the Greek translation of the BREQ-2, rendering it appropriate for continued self-determination exercise research among Greek-speaking exercise participants.

In this study, we examined the factor structure and internal consistency of the Flow State Scale using responses of exercise participants.This self-report questionnaire consists of nine subscales designed to assess flow in sport and physical activity. It was administered to 1231 aerobic dance exercise participants. Confirmatory factor analyses were used to test three competing measurement models of the flow construct: a single-factor model, a nine-factor model and a hierarchical model positing a higher-order flow factor to explain the intercorrelations between the nine first-order factors. The single-factor model showed a poor fit to the data. The nine-factor model and the hierarchical model did not show an adequate fit to the data. All subscales of the Flow State Scale displayed acceptable internal consistency ( f > 0.70), with the exception of transformation of time ( f = 0.65). Collectively, the present results do not provide support for the tenability of the single-factor, nine-factor or hierarchical measurement models in an exercise setting.

The effectiveness of an exercise intervention including both aerobics and resistance training components in improving physical self-perceptions and global self-esteem (GSE) in women with obesity was examined. An experimental design with a one-year follow-up was used. Women with obesity (n = 72) participated in a structured exercise programme for 12 weeks after being randomised into a control and an exercise group. Exercise self-efficacy, body attractiveness, physical strength, sport competence, physical condition, physical self-worth, and GSE were measured at pre-intervention, early intervention, mid-intervention, immediately after the intervention, and five times following programme termination at 1, 3, 6, 9, and 12 months, respectively. Analyses of covariance revealed exercise effects for all of the dependent variables except for body attractiveness. Generally, exercise effects lasted between 6 and 12 months. A 12-week physical exercise programme including aerobic and resistance training components has the potential to improve physical self-perceptions and self-esteem in women with obesity.

The present study investigated the nomological validity of the Amotivation Inventory–Physical Education ( Shen, Wingert, Li, Sun, & Rukavina, 2010b Shen, B. , Wingert, R. K. , Li, W. , Sun, H. and Rukavina, P. B. 2010b. An amotivation model in physical education. Journal of Teaching in Physical Education, 29: 72–84. [Web of Science ®] [Google Scholar] ) scores by examining the associations of ability, effort, value, and task characteristics amotivation beliefs with self-determination theory variables. Data were collected from 401 fifth- and sixth-grade students, 416 middle-school students, and 401 high-school students. After providing support for the correlated four-factor structure, the hierarchical structure, internal consistency, and composite reliability of the Amotivation Inventory–Physical Education scores, large negative correlations emerged with perceived autonomy support by the PE teacher; needs for autonomy, competence, and relatedness; identified regulation; intrinsic motivation; and students' subjective vitality. Strong positive correlations were obtained with unidimensional amotivation and external regulation, and weak correlations were obtained with introjected regulation. Also, multidimensional amotivation beliefs partially mediated the relationship between the need for autonomy and subjective vitality. The results provided support for the nomological aspect of construct validity of the Amotivation Inventory–Physical Education scores.
