Measuring general levels of physical activity: preliminary evidence for the Physical Activity Questionnaire for Older Children.

This article reports three studies that investigated psychometric properties of the Physical Activity Questionnaire for Older Children (PAQ-C). The PAQ-C is a guided self-administered 7-day recall measure designed to assess general physical activity levels during the school year for children in grades four and higher. Study one, with 215 students ranging in age from 9 to 15 yr, found the PAQ-C had acceptable item and test score characteristics such as item distribution, corrected item-total correlations, and internal consistency. Study two, involving 84 students ranging from 9 to 14 yr, indicated acceptable levels of test-retest reliability for both males (r = 0.75) and females (r = 0.82) after 1 wk. The third study used Generalizability theory to investigate the reliability for using the average of either two or three PAQ-C scores collected during fall, winter, and spring seasons. Based on the responses of 200 students ranging from 8 to 16 yr, generalizability coefficients exceeded 0.80 for either the average of two or three responses for both younger (<13 yr) and older subjects. In all three studies, the PAQ-C demonstrated acceptable internal consistency and males were significantly more active than females. These results provide preliminary support for the PAQ-C as a cost efficient method of assessing general levels of childrens physical activity during the school year.

Children's physical activity and physical self-perceptions.

The aim of this study was to determine the relationship between physical self-perceptions and physical activity in Canadian school children aged 10–14 years. The sample consisted of 220 boys and 246 girls in grades 5–8. Physical activity was assessed by 7-day recall using the Physical Activity Questionnaire for Older Children. Selfperceptions of physical conditioning, sports competence, strength, body appearance and general physical selfworth were measured by the Physical Self-Perception Profile (PSPP). We found that boys were more physically active than girls and had higher perceptions of sport competence and strength. All PSPP scales were significantly correlated with physical activity in both boys and girls. Structural equation modelling procedures found the hierarchical PSPP model provided a good fit to the observed data, with little evidence of diff erences between the sexes. Analysis of five alternative structural models of the relationship between the PSPP and physical activity found the most parsimonious model to have significant pathways from both physical conditioning and sport skills to physical activity. Models for the sample as a whole, for boys and for girls were similar, accounting for an R 2 of 0.27–0.29 for physical activity. Our results demonstrate that physical self-perceptions, especially physical conditioning and sport skills, are significant correlates of activity in this population.

Longitudinal Assessment of the Relationship Between Physical Self-Concept and Health-Related Behavior and Emotion in Adolescent Girls

This study investigated the changes in and the relationships among body mass index (BMI), global self-esteem, physical self-perceptions, social physique anxiety (SPA), physical activity, and dietary restraint in adolescent females over a 24-month period. Participants (N = 501) completed annual assessments in grade 9, 10, and 11. The results showed moderate covariance stability in all variables. There were several significant time effects (group mean change), with small increases in BMI, moderate decreases in physical activity, and very small changes over time in SPA and physical self-perceptions. Longitudinal analyses indicated that specific physical self-perceptions were important predictors of physical activity, dietary restraint and SPA; however, most of the variance was explained by previous year values. Evidence of bidirectional effects revealed that specific self-perceptions impact specific behaviors and SPA more so than the impact of behavior/emotion on self-perceptions. These results highlight the importance of understanding the physical self and its links to health-related behaviors and emotion in adolescents.

Social Physique Anxiety in Adolescence: An Exploration of Influences, Coping Strategies, and Health Behaviors.

This study explored adolescent females’ experiences of social physique anxiety (SPA) and related coping strategies. A final sample of 31 adolescent females ages 13 to 18 years discussed dealing with SPA during individual semistructured interviews. Resultant themes pertaining to the transactional experiences of SPA were coded using content analysis. There were 107 unique coping strategies reported, which were coded into 10 subthemes. The main coping categories included behavioral and cognitive avoidance, appearance management, diet, social support, physical activity, reappraisal, cognitive deflection and comparison to others, seeking sexual attention, and substance use. Informed by a stress and coping framework, it is evident that body-related thoughts and emotions are linked to various adolescent health behaviors.

Relationship between carbonated and other low nutrient dense beverages and bone mineral content of adolescents

Abstract Low nutrient dense beverages such as carbonated drinks are increasing in the adolescents diet, and concern has been raised that these beverages, particularly colas, reduce bone mass. We determined whether the type of low nutrient dense beverage as well as the amount was related to bone mineral content and accumulation during the two years spanning the time of peak bone mass accrual in adolescence. Total body bone mineral content (BMC) and dietary intakes were obtained for 59 boys and 53 girls when each subject was ± one year of his or her measured age of peak rate of BMC. Consumption of low nutrient dense beverages was negatively related to BMC (r = −0.256, P=0.03) and accrual (r = −0.227, P=0.05) for adolescent girls but not boys. Milk beverage intake in both boys and girls was inversely related to low nutrient dense beverage consumption (r = −0.343, P=0.01; r=−0.244, P=0.08, respectively). Low nutrient dense beverage ingestion by adolescents appeared to reduce bone mineral accrual and BMC in teenage girls by replacing milk beverages.

Physical Self and Physical Activity Relationships in College Women: Does Social Physique Anxiety Moderate Effects?

Abstract This research assessed whether social physique anxiety moderated the relationship between physical self-perceptions and the level of physical activity involvement in young women. Participants were 354 female students who completed the Social Physique Anxiety Scale (SPAS), Physical Self-Perception Profile, Self-Administered 7-Day Physical Activity Recall (PAR), and Leisure Time Exercise Questionnaire (LTEQ). Both physical activity measures were significantly related to the SPAS and all physical self-perceptions. Multiple regressions showed that only self-perceptions of conditioning significantly predicted PAR (R2 = .24) and LTEQ (R2 = .30). SPA did not add any unique variance in predicting activity, and no moderator effects were found for either PAR or LTEQ. Findings suggest that perception of physical conditioning is the dominant predictor of physical activity levels in young women, and social physique anxiety does not moderate this relationship.

The Role of Self-compassion in Women's Self-determined Motives to Exercise and Exercise-related Outcomes

Self-compassion is emerging in the literature as a healthy conceptualization of the self (Neff, 2003a). This study explored how self-compassion is related to, and explains unique variance beyond self-esteem on, womens motives to exercise and exercise-related outcomes. Participants were 252 women exercisers. Self-compassion was positively related to intrinsic motivation and negatively related to external and introjected motivation, ego goal orientation, social physique anxiety, and obligatory exercise behavior. Hierarchical regression analysis showed that self-compassion contributed unique variance beyond self-esteem on introjected motivation, ego goal orientation, social physique anxiety, and obligatory exercise. This study provides evidence that self-compassion is related to well-being in the exercise context, raising the possibility that the development of self-compassion may be important for women who exercise.

The contributions of goal characteristics and causal attributions to emotional experience in youth sport participants.

Abstract Objectives . To examine the role of causal attributions, goal importance, and goal discrepancy as predictors of discrete emotions in youth sport settings. More specifically, causal attributions and goal characteristics were examined in an actual performance test and a natural competitive setting. Both direct effects and moderator models were tested. Method . Two studies were conducted. In the first study, 130 adolescent soccer players completed the Leger fitness test, as well as measures of goal importance and objective goal discrepancy, and the CDSII to assess causal dimensions PANAS-X to assess emotions. In the second study, 174 adolescent swimmers and track and field athletes participated in sport-specific competitions. Participants completed the same battery of questionnaires as in the first study with the exception that a measure of subjective goal discrepancy replaced objective goal discrepancy. Results . Results showed general consistency across studies. Both causal dimensions and goal characteristics (importance and discrepancy) showed direct effects in the prediction of emotion. However, there was no support for theoretical links between causal dimensions and specific emotions. Little support was found for a moderator model examining the interactions among and between goal characteristics and causal dimensions. In addition, subjective performance discrepancy was a much stronger predictor of emotion in the second study compared with objective performance discrepancy in the first study. Conclusions . Although causal attributions and goal characteristics are important predictors of emotion, there was little support for the theoretical model proposing an interaction among these variables in the experience of emotion for youth sport participants.

Body-Related Emotional Experiences of Young Aboriginal Women

Concerns related to the body are associated with health-compromising behaviors, and although research has indicated that young Aboriginal women are dissatisfied with their bodies, their voices have typically been absent from the literature. The purpose of this case study was to provide insight into the body-related emotional experiences of young, Canadian, urban Aboriginal women. Four young women participated; 3 identified themselves as Aboriginal (one 14-year-old, two 18-year-olds) and 1 as non-Aboriginal (18 years old). Multiple methods (focus group, one-on-one interviews, and artwork) provided the authors the opportunity to listen to the young womens stories. Five themes emerged: (a) conflicting cultures, (b) need to belong, (c) the beauty of difference, (d) journey to acceptance of the body, and (e) the body affects everything. This research highlights the complexity of young Aboriginal womens body-related emotional experiences and indicates that their experiences might not be as negative as previous research has led us to believe.

Exploring women track and field athletes' meanings of muscularity.

Women athletes often struggle with attaining the muscular body needed to compete successfully, while at the same time negotiating expectations to conform to a lean and toned ideal. The purpose of this study was to explore women track and field athletes’ meanings of muscularity. Four adult and four adolescent women participated in focus groups and one-on-one interviews, exploring issues surrounding the body, including ideals and expectations. The participants also took photographs to represent their perceptions of their own muscularity. Four themes emerged: (a) many faces of muscularity, (b) a blurred line between appearance and performance, (c) a culture of comparison, and (d) a journey towards self-acceptance. Muscularity was identified as a complex and context specific experience, reflecting the multiple meanings of muscularity and the periods of struggle on the journey towards self-acceptance of the body.
