Group Cohesion, Achievement Motivation, and Motivational Outcomes among Female College Students

Embedded in the theory of group cohesion and the expectancy-value model of achievement choice, the purpose of this study was to examine the predictive strengths of group cohesion on students’ motivation (expectancy-related beliefs and subjective task values) and motivational outcomes (exercise choice and class attendance) in college physical activity classes. Participants were 121 females enrolled in aerobics classes who completed questionnaires assessing group cohesion, motivational constructs, and exercise choice. Group cohesion constructs were significantly associated with motivation and motivational outcomes. These findings provide insight into how to design environments to promote motivation in physical activity classes.

Motivational processes in children's physical activity and health-related quality of life

Background: School physical education (PE) not only offers and promotes health-related physical activity (PA), but also encompasses the promotion and development of health-related well-being such as health-related quality of life (HRQOL). Furthermore, assessing PA and HRQOL have become major issues in pediatric public health and also serve as a major goal of Healthy people 2020. Grounded in the expectancy-value and achievement goal frameworks, the primary purpose of this study was to examine the relationships among the perceptions of motivational climate in PE, expectancy-value beliefs, HRQOL, and PA among elementary children. A secondary purpose was to test whether expectancy-value beliefs mediate the relationship between motivational climate and HRQOL as well as between motivational climate and PA (self-reported PA and pedometer-based PA, respectively). Methods: Participants were 336 elementary children recruited from three public schools in the southeastern USA (Mage = 9.87; 179 girls, 157 boys). The majority of the participants (53.3%) were White students and the remainder (46.7%) including African-American (37.4%), Asian-American (1.5%), Hispanic-American (1.8%) and others (5.9%). Students completed a previously validated questionnaire assessing expectancy-related beliefs and task values toward PE. The 23-item pediatric QOL inventory generic core scale (PedsQLTM 4.0) was used to assess participants’ HRQOL. Childrens PA levels were assessed by using a self-reported survey (Physical Activity Questionnaire for Older Children) and three-day pedometer counts (steps/min during PE). Analysis/Results: Correlational analyses showed that expectancy-related beliefs and task values were positively related to PA and HRQOL. Regression analyses indicated that both mastery and performance motivational climate had a positive effect on childrens expectancy beliefs and task values. Mediational analyses were used to evaluate the potential mediational relationships among motivational climate (independent variables: mastery and performance climates), expectancy-value beliefs (mediator: expectancy-value beliefs), and HRQOL and PA (dependent variables: total HRQOL score, self-reported PA and steps/min), respectively. Conclusions: A mastery motivational climate together with high expectancy beliefs has a positive association with HRQOL, which in turn could produce health benefits in the future. Results suggest that a performance motivational climate could be associated with less activity (i.e. lower steps/min) even when students view PE as interesting, important, and useful. One important implication of the study is that by promoting mastery climates and expectancy-value beliefs in PE practitioners can encourage children to engage in PA both in and outside of school, and consequently may influence their quality of life.

College Students' Physical Activity and Health-Related Quality of Life: An Achievement Goal Perspective

Purpose: The 2 × 2 achievement goal model, including the mastery-approach, mastery-avoidance, performance-approach, and performance-avoidance goal orientations, has recently been used to explain motivational outcomes in physical activity. This study attempted to examine the relationships among 2 × 2 achievement goal orientations, physical activity, and health-related quality of life (HRQOL) in college students. Method: Participants were 325 students (130 men and 195 women; Mage = 21.4 years) enrolled in physical activity classes at a Southern university. They completed surveys validated in previous research assessing achievement goal orientations, physical activity, and HRQOL. Results: Path analyses revealed a good fit between the model and data (root mean square error of approximation = .06; Comparative Fit Index = .99; Bentler-Bonett Nonnormed Fit Index = .98; Incremental Fit Index = .99), but the model explained small variances in the current study. Mastery-approach and performance-approach goal orientations only had low or no relationships with physical activity. Mastery-approach goal orientation and physical activity also had low positive relationships with HRQOL, but mastery-avoidance and performance-avoidance goal orientations had low negative relationships with HRQOL. The hypothesized mediational role of physical activity in the relationship between mastery-approach and performance-approach goal orientations and HRQOL was not supported in this study. Conclusions: Although the data fit the proposed model well, only small variance was explained by the model. The relationship between physical activity and HRQOL of the college students and other related correlates should be further studied.

Impact of a pedometer-based goal-setting intervention on children’s motivation, motor competence, and physical activity in physical education

ABSTRACT Background: School physical education (PE) programs provide a prime environment for interventions that attempt to develop school-aged children’s motor competence and overall physical fitness, while also stimulating competence motivation to engage in physical activity during childhood. It is generally recognized that a pedometer-based intervention strategy combined with a goal-setting strategy may be effective in increasing physical activity participation among school-aged children. The purpose of this study was to evaluate the impact of an 8-week pedometer-based goal-setting intervention on children’s motivation in PE, motor competence, and physical activity. Methods: A pretest–posttest comparison group design was used with the 8-week intervention (3 days/week for 24 sessions). Participants were 273 (boys = 136, girls = 137) students recruited from 3 elementary schools in the US. Classes in each school were randomly allocated to three experimental conditions: (1) an intervention group with a personalized pedometer weekly target to reach in their PE class (N = 110), (2) an intervention group with the fixed pedometer target range to reach in each PE class based on the recommended criteria (N = 90), or (3) a control group without intervention (N = 73). Analysis/results: The factorial repeated measures MANOVA indicated significant multivariate effects for the group [F(6, 528) = 12.954, p < .001]. Post hoc analyzes showed that both experimental groups had significantly higher expectancy-value beliefs, motor competence, and physical activity compared to the control group (p < .001). Conclusions: Health practitioners should be aware that goal-directed action can contribute to school students’ PE-related achievement motivation, motor competence, and achieving the recommended 60 min of moderate-to-vigorous physical activity.

Understanding Adolescents' Mental Health and Academic Achievement: Does Physical Fitness Matter?.

Despite consensus that physical fitness (PF) plays an important role in promoting mental health and academic achievement, little is known regarding the mechanisms by which this effect works. Blair, Cheng, and Holder (2001) proposed a conceptual model to identify the behavioral mechanism of health outcomes, in which both health-related PF and skill-related PF were identified as the direct determinants of health outcomes. Guided by Blair and colleagues’ model, the primary purpose of this study was to examine the association between health-related PF, skill-related PF, depression and academic achievement among adolescents. The second purpose was to investigate whether depression would mediate the association between physical fitness and academic achievement among this population. A total of 144 adolescents (M age = 14.55, SD = 0.62) were recruited from two middle schools. Health-related PF was significantly associated with depression, and skill-related PF was related to academic achievement. Mediation analysis supports the statistically significant indirect effect of depression on the relation between health-related PF and academic achievement. The findings suggest that individuals who are physically fit and show positive mental functioning may have better academic achievement during adolescence.
