AimThis research sought to identify the process by which women who identify as fat or as not having a typical athletic body construct an athletic identity and persist in their running and other athletic endeavors despite body size-related barriers.MethodsFrom an online recruitment effort, 19 North American women runners in larger bodies completed interviews in which they told the story of how they had become runners. A narrative analysis with a feminist, constructivist approach was conducted to identify story types.ResultsFour narrative types were identified: reclaiming the body, reclaiming health, space-making, and future-imagining. Through finding a size- and pace-inclusive running community, running persistently, and completing races, women relinquished the stories they’d believed that their bodies were not athletic since childhood and constructed an identity of runner in a fat body.ConclusionsThese women’s engagement in running is a personal form of resistance against those who define athletic and healthy as “thin” or “fit.” They have found a welcoming athletic community and have moved on to leadership where they are working to make running accessible to other women in bodies like theirs. Those reading these narratives should consider ways in which fat bodies have been excluded from athletics, as well as ways to support the work being done by women runners in fat bodies to redefine health and athleticism.  相似文献

The cognitive discrepancy model predicts that loneliness occurs when individuals perceive a difference between their desired and actual levels of social involvement. Using data from a sample of high school sophomore students, the present investigation was designed to go beyond previous research that has tested this model by examining the predicted nonlinear relationships between desired and actual social contact and feelings of loneliness. Analyses indicated that support for the cognitive discrepancy model of loneliness was found only for measures of close friendships. Specifically, the discrepancy between the students' ideal number and actual number of close friends was found to be related in a nonlinear fashion to feelings of satisfaction with close friendships and loneliness after control for the number of close friends. Implications of these findings for theoretical models of loneliness are discussed.  相似文献

Objectives

This study examined how variations in the activity of adolescents might relate to the social influences used by parents. Specifically, mean differences in activity across adolescents (individual differences) as well as variation in activity within adolescents (intra-individual variation) were used to predict the use of family social influence.

Design

A prospective design was used.

Methods

High school students (N = 329) completed measures of activity (six times) and social influences received from family (positive, negative, collaborative) (five times) over a one-year period. A multilevel analysis was used to predict each of the three types of social influence. The predictors included activity in two forms: The individual’s mean level of activity (i.e., individual differences) and activity at the previous time point as a deviation from the individual’s mean activity level (i.e., intra-individual variation).

Results

Controlling for age, gender and school, results revealed that both individual differences in mean activity level (b = 0.04, p < .001) and intra-individual variation in activity (b = −0.02, p = .055) predicted use of collaborative influence. For positive influence, only individual differences in mean activity level was a predictor (b = 0.02, p < .001). Neither form of activity predicted parental use of negative influence.

Conclusions

Results revealed support for the positive relationship between both positive and collaborative types of influence and individual differences in activity that is typically reported in the literature. However, a negative relationship between intra-individual variation in activity and collaborative social influences also was found. This negative relationship, where lower activity than normal by the adolescent was related to a greater use of collaborative influence by the parent, may be indicative of a regulatory form of social influence.  相似文献

Objectives

In educational contexts, Lent and Lopez (2002) proposed that students develop a tripartite network of efficacy beliefs, comprising their confidence in their own capabilities (i.e., self-efficacy), their confidence in their teacher’s ability (i.e., other-efficacy), and their estimation of their teacher’s confidence in their ability (i.e., relation-inferred self-efficacy). In spite of the potential for school-based physical education (PE) to stimulate leisure-time activity patterns among adolescents, it is noteworthy that this framework has yet to be explored in school PE contexts.

Design and methods

In Phase 1, we recruited 62 Australian high school students (aged 11-13) in order to develop instruments designed to assess self-efficacy, other-efficacy, and relation-inferred self-efficacy within PE settings. In Phases 2 and 3, we sought to provide evidence for measurement reliability, validity, and invariance with cross-sectional and prospective data derived from Australian (N = 602, Mage = 13.54, SD = .76) as well as Singaporean (N = 606; Mage = 14.10, SD = 1.01) students.

Results

Results revealed (a) support for the factorial validity of these measures in both locations, (b) evidence of gender-related and cross-national measurement invariance, (c) positive inter-relationships between students’ tripartite efficacy perceptions that were consistent with theory, and (d) positive correlations with key in-class (e.g., effort, enjoyment) and leisure-time (e.g., physical activity levels) outcomes.

Conclusions

Taken together, the results provide preliminary evidence for the reliability and validity of measures derived from these tripartite efficacy instruments, and support their use in future research designed to examine PE engagement.  相似文献

Using self-determination theory (SDT) as an explanatory framework, this randomised-controlled study evaluates the effect of a motivational interviewing (MI)-based intervention as an addition to a standard weight loss programme (SWLP) on physical activity (PA) practice in obese adolescents over a six-month period. Fifty-four obese adolescents (mean age?=?13?years, mean BMI?=?29.57?kg/m²) were randomly assigned to an SWLP group (n?=?28) or SWLP?+?MI group (n?=?26). Both groups received two SWLP sessions, supplemented for the SWLP?+?MI group, by six MI sessions. Perceived autonomy support, perceived competence, motivational regulations, PA and BMI were assessed at baseline, three and six months (i.e. the end of the programme). MLM analyses revealed that compared to SWLP, the SWLP?+?MI group had a greater BMI decrease and a greater PA practice increase over time. Moreover, the SWLP?+?MI group reported greater autonomy support from medical staff at the end of the programme, greater increase in integrated and identified regulations and a stronger decrease in amotivation. MI appears as an efficient counselling method as an addition to an SWLP to promote PA in the context of pediatric obesity.  相似文献

This longitudinal study examined whether habit strength moderates the intention–physical activity (PA) relationship in older adults, within the framework of the attitude–social influences–efficacy (ASE) model and the theory of planned behaviour (TPB). A total of 1836 older adults (M age?=?62.95?years, SD age?=?8.17) completed a questionnaire on social cognitive constructs and PA habit strength at baseline, and six?months later a measure of PA. Three PA habit groups (i.e. low, medium and high) were composed, based on tertiles of the mean index score. Multi-group structural equation modelling analyses showed that intention significantly determined PA behaviour only in participants with a low or medium habit strength towards PA. This result suggests that PA is not intentional at high levels of habit strength and demonstrates the usefulness of incorporating habit in the ASE and TPB models. Results also showed that about half of the participants with a strong PA habit did not meet the recommended PA level. As strong habits may prevent intentional behavioural change and may hinder the receptiveness and openness for informational PA change strategies, additional intervention strategies, such as awareness raising and the use of implementation intentions, are needed for strongly habitual, but insufficiently active older adults.  相似文献

This study investigated whether Negative Affectivity (NA) causes bias in self-report measures of activity limitations or whether NA has a real, non-artifactual association with activity limitations. The Symptom Perception Hypothesis (NA negatively biases self-reporting), Disability Hypothesis (activity limitations cause NA) and Psychosomatic Hypothesis (NA causes activity limitations) were examined longitudinally using both self-report and objective activity limitations measures. Participants were 101 stroke patients and their caregivers interviewed within two weeks of discharge, six weeks later and six months post-discharge. NA and self-report, proxy-report and observed performance activity (walking) limitations were assessed at each interview. NA was associated with activity limitations across measures. Both the Disability and Psychosomatic Hypotheses were supported: initial NA predicted objective activity limitations at six weeks but, additionally, activity limitations at six weeks predicted NA at six months. These results suggest that NA both affects and is affected by activity limitations and does not simply influence reporting.  相似文献

Objective: Using a moderated mediation model, the present study investigated whether the mediation of intention into physical activity (PA) behaviour via action planning depends on the level of coping planning.

Method: A four-month prospective study was conducted among 157 French adults, who were recruited through a web-based survey. They were administrated measures of behavioural intention and sociodemographic variables at baseline and action and coping planning and PA four months later.

Results: Action planning partially mediated the contribution of intention on PA level. However, this indirect effect was conditional on the level of coping planning, insofar as action planning acted as a mediator of the intention–PA relationship only for individuals with high level of coping planning.

Conclusion: The results highlight the complexity of the relationship between intention and behaviour and provide evidence for the distinct role of both forms of planning.  相似文献

Objective: Physical activity is a key factor for healthy ageing, yet many older people lead a sedentary lifestyle. Traditional physical activity interventions do not consider the specific needs and views of older adults. As views on ageing are known to be related to health behaviours, the current study evaluates the effectiveness of prompting positive views on ageing within a physical activity intervention.

Design: Randomised controlled trial with three groups aged 65+: Intervention for physical activity with ‘views-on-ageing’-component (n?=?101; IGVoA), and without ‘views-on-ageing’-component (n?=?30; IG), and active control intervention for volunteering (n?=?103; CG).

Main outcome measures: Attitudes towards older adults and physical activity were assessed five weeks before intervention, two weeks, six weeks and 8.5?months after the intervention.

Results: Compared to the IG and CG, positive attitudes towards older adults increased in the IGVoA after the intervention. For IGVoA, the indirect intervention effect on change in activity via change in attitudes towards older adults was reliable.

Conclusion: A ‘views-on-ageing’-component within a physical activity intervention affects change in physical activity via change in views on ageing. Views on ageing are a promising intervention technique to be incorporated into future physical activity interventions for older adults.  相似文献
