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.

The Posttraumatic Growth Inventory: an examination of the factor structure and invariance among breast cancer survivors

Objective: The present study tested the proposed five‐factor structure and invariance of the Posttraumatic Growth Inventory (PTGI; Tedeschi & Calhoun, 1996) in a sample of physically active breast cancer survivors.

Predicting changes in posttraumatic growth and subjective well‐being among breast cancer survivors: the role of social support and stress

Social support is theoretically expected to be positively associated with posttraumatic growth (PTG) and subjective well‐being, and stress is expected to be positively associated with PTG and negatively associated with subjective well‐being among breast cancer (BC) survivors. However, empirical evidence is mixed, predominantly cross‐sectional, and few studies have examined the unique effects of these predictors on positive changes in psychological experiences post cancer diagnosis and systemic treatment. This study examined both general and BC‐specific social support and stress as predictors of change in PTG and subjective well‐being among BC survivors.

Sport Participation Motivation in Young Adolescent Girls: The Role of Friendship Quality and Self-Concept

Abstract This study examined the factor structure of the Sport Friendship Quality Scale (SFQS; Weiss & Smith, 1999) and compared two models in which (a) self-worth mediated the relationship between physical self/friendship quality and sport commitment and (b) friendship quality and physical self-perceptions directly predicted self-worth and sport commitment. Female team sport participants (N= 227) between the ages of 11 and 14 years completed measures of sport commitment, enjoyment, athletic competence, physical attractiveness, self-worth, and friendship qualities. A confirmatory factor analysis found an inadequate fit for the SFQS, mainly due to problems with the loyalty and intimacy subscale. Separating the loyalty and intimacy factor into two subscales provided an adequate fit. Examination of the two structural models indicated that both models provided an adequate overall fit but that self-worth only weakly predicted sport commitment, suggesting the mediator model was impractical. Friendship quality had a weak relationship with self-worth and sport commitment. Results are discussed in light of issues in measuring sport friendship quality and future directions in this developing field.

Social Connection and Psychological Outcomes in a Physical Activity-Based Youth Development Setting

It is believed that the social connections formed by participating in physical activity-based positive youth development (PYD) programs contributes to building personal and social assets. In this study, we examined how changes in social connection over a physical activity-based PYD program for low-income youth were associated with changes in psychological outcomes. Participants (N = 197) completed pre- and postprogram questionnaires assessing leader support, social competence, physical competence, and psychological outcomes (global self-worth, physical self-worth, attraction to physical activity, and hope). Social competence, physical competence, physical self-worth, and global self-worth increased significantly over the 4-week program. Changes in social connections predicted changes in psychological outcomes. Effect sizes were modest but suggest that social interventions hold potential to promote positive outcomes in underserved youth.

An Interpretative Phenomenological Examination of Psychosocial Changes among Breast Cancer Survivors in their First Season of Dragon Boating

This study used an interpretative phenomenological perspective to qualitatively examine changes in body image and social support experienced by novice participants in breast cancer survivor dragon boating programs. Fourteen women were interviewed at the beginning and end of their first dragon boating season. The participants typically experienced increased perceptions of strength and fitness, and a shift towards discussing body image with respect to fitness, strength, and musculature rather than weight and appearance. Many women discussed an emerging athletic identity. Social benefits included connecting to women who understood the breast cancer experience and could share first-hand information. Some women also reported struggling with the constant reminder of being a survivor. Overall, breast cancer survivors experienced benefits, but further work should explore how they cope with challenges and how dragon boating could inform other physical activity contexts for this population.

Correlates of long-term participation in a physical activity- based positive youth development program for low-income youth: Sustained involvement and psychosocial outcomes

This study examined correlates of long-term participation in a positive youth development (PYD) program. Low-income youth (N = 215) age 8-13 of diverse ethnicity participating in a summer physical activity-based PYD program completed questionnaires at the beginning and end of the program (year 1) and at the beginning of year 2. Those with lower BMI and higher attendance and leader support perceptions were more likely to return to the program the following year. Self-worth and leader support perceptions at time 2 were higher for returners compared to non-returners. Among returners, hope increased from year 1 to year 2 and increases in global self-worth across the first year were maintained over one year. Social support is linked to continued PYD participation. Returners had increased and/or sustained positive perceptions of self-worth and hope. Programs are encouraged to foster staff-participant relationships and self-worth, and minimize barriers associated with weight status.

Psychosocial and environmental factors associated with dog-walking

Dog walking is associated with higher levels of physical activity (PA). However, not all dog owners walk their dog(s) at a level sufficient for health benefits. Therefore, identifying correlates of dog-walking may help to inform the design of more effective interventions to promote this specific form of PA. The purpose of this study was to examine psychosocial and environmental correlates of dog-walking and relationships of dog-walking with overall PA. In 2010, 391 dog owners (mean age = 43.6 ± 12.3 years) completed a survey. Multiple logistic regression and structural equation modeling were used to examine psychosocial and environmental correlates of dog-walking status, weekly minutes of dog-walking, and relationships of dog-walking with overall PA. Self-efficacy for dog-walking, dog-related outcome expectancies, family social support, dog social support, and neighborhood walking environment were associated with a 1.3–5.6 greater odds of being a dog walker. Self-efficacy mediated relationships between family support, dog support, and presence of a yard and dog-walking. Neighborhood environment, including the presence of greenery and trails, was also positively associated with duration of dog-walking (β = 0.17; p < 0.05). Every 30-minute increase in dog-walking was associated with a 23% greater odds of meeting PA guidelines by walking. Individual, social, and environmental factors consistent with a social–ecological framework were positively associated with dog-walking. Individuals were more likely to meet PA guidelines if they walked their dog(s) and engaged in dog-walking for longer duration.

Muscle gains and emotional strains: conflicting experiences of change among overweight women participating in an exercise intervention program.

In this study we explored the experiences of women who were classified as overweight while they participated in a physical activity intervention. In line with interpretative phenomenological analysis, eight women were interviewed prior to and following a 12-week dragon boat physical activity intervention. Data were transcribed verbatim and subjected to individual-level content analysis to explore change that informed group-level idiographic analysis. From the idiographic analysis three distinct profiles were created: (a) women who consistently struggled with negative self-perceptions; (b) women who consistently experienced positive self-perceptions; and (c) women who began with negative self-perceptions and developed more positive self-images. These profiles appeared to be associated with age, since the youngest women placed significant emphasis on the body and physical appearance, whereas the oldest participants reported the most significant shift from importance of body to a greater emphasis on health and well-being. The findings, which are reported in the context of self-determination theory, suggest that women in each of these profiles had unique physical and social self-perceptions and distinct social interactions within the dragon boat intervention.

Social Responsibility among Low-Income Youth in Physical Activity-Based Positive Youth Development Programs: Scale Development and Associations with Social Relationships

Relationships with peers and adults are expected to foster social responsibility in physical activity-based positive youth development programs. Low-income youth (N = 479) were surveyed pre- and post-program.Psychometric properties of a new social responsibility scale were supported. Belonging predicted changes in social responsibility, and leader emotional support moderated the autonomy support- and belonging-social responsibility associations. Those with higher leader emotional support had a stronger positive association between autonomy support and social responsibility. Those with lower leader emotional support had a stronger positive association between belonging and social responsibility. Positive social relationships with peers and staff may facilitate social responsibility.
