Objective: Self-efficacy and physical activity (PA) enjoyment are related to PA behaviour, but it is unclear which is more important and how they interrelate. The purpose of this study was to examine how these two constructs interrelate to influence PA behaviour.

Design: Participants were low-active adults (n = 448) participating in a RCT examining the effect of a PA promotion intervention. Participants completed physical activity, enjoyment and self-efficacy measures at baseline, six and 12 months.

Results: Self-efficacy and enjoyment at both baseline and six months predicted PA at 12 months. However, enjoyment was a stronger predictor than self-efficacy, in that self-efficacy no longer predicted PA behaviour when included alongside enjoyment. In follow-up mediation analyses, enjoyment at six months did not mediate the effect of baseline self-efficacy on 12-month PA; however, six-month self-efficacy mediated the effect of baseline enjoyment on 12-month PA.

Conclusion: Our results indicate that interventions should perhaps initially focus on increasing enjoyment of physical activity. Greater PA enjoyment appears to influence individuals’ self-reported ability to engage in regular PA (i.e. higher self-efficacy ratings). Additional research is needed to better understand the interrelationships between self-efficacy and enjoyment and how these constructs affect PA.  相似文献

Objective: To uncover the rationale underlying the perceived distinction between clusters of health behaviours by identifying cognitive constructs that differentiate among them, and creating a ‘cognitive profile’ for each behavioural cluster. Thus, different determinants and characteristics of health behaviours (e.g. ‘perceived behavioural control’, ‘impact on health’, ‘effort’, ‘non-health rewards’, ‘habit’) were used to compare health behaviour meta-clusters (physical and psychosocial) and clusters (e.g. nutrition behaviours, substance abuse, medical practices).

Methods: A sample of lay people (N = 1956) judged items representing behavioural clusters delineated in the Health Behaviour Taxonomy on 14 constructs.

Results: Significant differences emerged between the physical and psychosocial meta-clusters, as well as among their sub-clusters. For example, physical behaviours were higher on ‘perceived behavioural control’ and ‘impact on health’ compared to psychosocial behaviours, and nutrition was perceived highest on ‘effort’ and ‘non-health rewards’ compared to the other clusters of the physical meta-cluster.

Conclusion: The findings increase our understanding of the logic underlying lay people’s cognitive schema of health behaviour clusters. ‘Cognitive profiles’ that explain differences between the clusters were identified, which can be used to design health messages and interventions targeting multiple health behaviours.  相似文献

Grounded in expectancy value theory (EVT), a moderated mediation model predicting children’s physical activity (PA) enjoyment was tested. Ability beliefs and subjective task value were initially investigated as mediating the relationship between social support from friends and PA enjoyment. It was hypothesized that children play an active role in this socialization process with support seeking self-efficacy moderating the mediated relationships. Findings revealed PA social support from friends and PA enjoyment was mediated by PA ability beliefs, but this mediated relationship was conditional on children having average-to-high levels of support seeking self-efficacy. The mediated relationship between PA social support from friends and PA enjoyment through subjective task value was not moderated by support seeking self-efficacy. Results support the importance of instilling confidence in children to seek out PA support in order to maximize opportunities for PA enjoyment and suggest pathways may be more complex than originally posited in EVT.  相似文献

This paper offers a preliminary account of the educative potential of mindfulness by revisiting the long-debated status of physical activity and sport as educationally worthwhile. We argue that previous attempts in the tradition of analytic philosophy of education to offer a justification of physical activity and sport have not been sufficiently grounded in the most distinctive feature of those activities—the body. As an alternative, we claim that the theory and practice of body-based mindfulness can explain how physical activity can satisfy the analytic philosopher of education R.S. Peters’ requirement that for an activity to be educationally worthwhile, it must possess ‘wide-ranging cognitive content’. We conclude that physical activity and sport are justifiable on Petersian grounds: physical activity can broaden understanding mostly inaccessible to the kinds of theoretical activities (science and/or philosophy) that Peters argued are exemplary. We then assess the implications for this argument in terms of how such an account can inform physical educators’ understanding of the place of physical education and sport in their teaching practice.  相似文献

This study examined physical training and observational training influences on motor learning and the development of visual discrimination processes. Participants were trained on a bimanual task (relative phase of +90°) defined by a visual training stimulus. There were 2 observational contexts: 1) model-only, watch a learning model, and 2) stimulus-only, watch the visual training stimulus. After 2 d of training, the learning models performed the +90° pattern with reduced error in 2 retention tests. Each observer group showed improvement in performance of the +90° pattern, with the stimulus-only group characterized by a more significant improvement. The learning models and observer groups were characterized by an improvement in visually discriminating 2 features of the trained pattern, relative phase and hand-lead. Overall, physical practice (learning models) established a stronger link between the action and visual discrimination processes compared with the observational contexts. The results show that the processes supporting action production and the visual discrimination of actions are modified in ways specific to the trained action following both physical and observational training.  相似文献

According to sanctification theory, religious people tend to imbue certain aspects of their lives with spiritual character and significance. Moreover, they take active steps to preserve and protect sacred aspects of their lives that might be threatened. If they are successful, they derive a deep sense of satisfaction and well‐being. However, when stressful events arise, some individuals are not able to preserve and protect the facets of their lives that they have come to view as sacred. The resulting sacred loss/desecration can be associated with physical and mental health problems. The purpose of the current study is to see if a sense of meaning in life buffers (i.e., moderates) the relationship between sacred loss/desecration and four measures of health: physical functioning, the number of chronic conditions, symptoms of physical illness, and self‐rated health. Data from a recent nationwide survey (N = 2,104–2,107) suggest that the negative relationship between sacred loss/desecration and each health outcome is lower for people who have a stronger sense of meaning in life.  相似文献

We examined social role functioning and depressive symptoms of young adults who were abused as children in data from a longitudinal community sample. Sexually abused women and men were more depressed during their senior year of high school, and this difference was more pronounced 2 years later. We then examined a mediational model to determine whether social functioning explained the course of depressive symptoms over this transitional period. Focusing only on young women, for whom the prevalence of abuse was much higher, results indicated that two-thirds of the effect of abuse on depressive symptoms was explained by experiences and choices in the domains of work, education and intimate relationships. Having less supportive intimate relationships and lower rates of attendance at 4-year colleges were particularly important. Findings reveal the key role played by early adult interpersonal and occupational development in perpetuating the mental health impact of childhood trauma.  相似文献

Both children and adults with disabilities face increased prevalence of abuse and assault, including sexual assault. Women and girls are disproportionately the victims of sexual assault in both disabled and nondisabled populations. Communication difficulties have been identified as a factor that may increase the vulnerability of individuals with disabilities to sexual assault. However, few studies have examined whether language impairment increases risk for sexual assault. This study reports on a community sample of children with speech or language impairment, followed to age 25. Sexual assault history was assessed based on two questions from the Composite International Diagnostic Interview Posttraumatic Stress Disorder module. Women with language impairment (n = 33) were more likely than women with unimpaired language (n = 59) to report sexual abuse/assault, controlled for socioeconomic status. Sexual assault was associated with higher rates of psychiatric disorders and poorer functioning. Women with neither language impairment nor a history of sexual assault had fewer psychiatric disorders and higher functioning than women with language impairment and/or a history of sexual assault.  相似文献

At the heart of the most radical proposals in Stuart Kauffman's Investigations is his attempt to show that we find in evolutionary biology some configuration spaces—the sets of possible developments for any given system—that (unlike those in traditional physics of Newtonian, relativistic, and quantum stripes) cannot be completely described in advance. We bring Charles Peirce's work on the philosophy of continuity to bear on the problem and discover, first, that Kauffman's arguments do not succeed; second, that Peirce's metaphysics provide new and sounder arguments for the same propositions; third, that Peirce's rigorous but nonstandard treatment of mathematical continuity shows great promise for modeling the unpredictability and growth we find in evolutionary biology; fourth, that it also strengthens a development only hinted at by biologists thus far—the inevitable involvement of the observer's mind in constituting the objects of science. We close with a logical argument for the surprising relevance of metaphysical hypotheses in the natural sciences and with suggestions for future work that will connect these questions to what Kauffman terms the “narrative stance” in biology.  相似文献
