Despite well-documented evidence implicating physical activity (PA) in the prevention of type 2 diabetes, the overwhelming majority of individuals with prediabetes are not physically active enough. The purpose of this study was to investigate the applicability of the social cognitive theory (SCT) in understanding PA behaviour in individuals with prediabetes. Individuals with prediabetes (N = 232) completed a mailed questionnaire assessing demographics, self-reported PA (MET.min/wk) and SCT constructs for PA MET.min/wk. For PA MET.min/wk, scheduling and task efficacy both had significant effects on PA (β = .30 and .22, respectively). Goal formation also had a direct effect on PA for scheduling, coping and task efficacy (β = .20, .34 and .30, respectively). Task, coping and scheduling efficacy explained a significant portion of the variance in PA behaviour. Overall, SCT appears to have merit as a model for understanding PA in individuals with prediabetes. Further evaluative inquiry is needed to establish support for the use of the SCT as a framework for developing, implementing and evaluating PA behaviour change interventions in this population.  相似文献

Physical activity has been found to have a number of benefits for lung cancer patients yet very little information is available concerning physical activity beliefs and preferences for this population. The purpose of the study was to explore physical activity programming and counseling preferences and beliefs about physical activity in newly diagnosed lung cancer patients scheduled to receive chemotherapy. A total of 43 new diagnosed lung cancer patients completed a researcher-administered survey prior to commencing chemotherapy. Results indicated that only 7 participants (17%) reported meeting public health recommendations for physical activity yet the majority of participants (n = 28) indicated interest or possible interest in physical activity counseling. Many participants also indicated interest or possible interest in an exercise program (n = 29) for lung cancer survivors, preferring it to start during chemotherapy (n = 20), for it to be home based (n = 21), and moderate in intensity (n = 22). The most common behavioral belief (advantage) of physical activity was to build/maintain strength (n = 26) and the most common control belief (barrier) was fatigue (n = 11). These data suggest that physical activity counseling and programming may be well received by newly diagnosed lung cancer patients. Information about physical activity and programming preferences and beliefs from this study may be useful for the design of optimal physical activity interventions for lung cancer patients.  相似文献

This study aimed to investigate the role of psychosomatic problems in the relationship between physical activity and healthrelated quality of life. Participants were a convenience sample of 703 students from a South African university (males = 38.8%, females = 61.2%, mean age = 19.6 years, SD = 1.26 years). The students completed measures of physical activity, psychosomatic-related health problems and quality of life-related. The hypothesised model was tested using structural equation modelling (SEM). The empirical findings revealed that psychosomatic problems mediated the relationship between physical activity and quality of life. In fact, the mediation analyses showed a partial effect of physical activity on quality of life in that those students with less self-reported activity experienced several psychosomatic-related health problems.  相似文献

To determine whether habitual physical activity status specifically influences executive function change in Alzheimer’s disease (AD) over 1 year. In this longitudinal cohort study, 45 participants with AD were recruited and provided follow-up data approximately 1 year later. Executive function measures (map search task, digit symbol substitution task, controlled oral word association task, verbal fluency task) and habitual physical activity measures (Physical Activity Scale for the Elderly (PASE) and handgrip strength) were taken at baseline and follow-up. Individual composites were subsequently created. Additional demographic, lifestyle, and neuropsychiatric measures were also taken. In a structural equation model (χ2(26) = 9.84, p = .998, comparative fit index = 1.00, root mean square error of approximation = .00), a significant association was found between habitual physical activity and executive function change (β = .27, p = .04). In a cross-lagged panel analysis, a significant path was found between the PASE score and executive change (β = .22, p = .01). As higher habitual physical activity levels were associated with reduced executive function change, the promotion of low-intensity habitual physical activities in individuals with a diagnosis of AD may be warranted. Further research is needed, however, to explore the impact of habitual physical activity on the trajectory of change across cognitive domains, and how this relates to the progression of the underlying pathology associated with this disease.  相似文献

ObjectiveRegular dog walking is likely a symbiotic relationship between the needs of the dog and its owner. This relationship has seen limited attention. The purpose of this study was to examine the relationships between dog characteristics, dog owners' perceptions of responsibility and attachment to their dogs, and the qualities of dog owner exercise motivations (self-determined regulations) with dog walking behavior.MethodParticipants were 228 adult dog owners who completed an online survey that included demographics, dog walking, dog responsibility/attachment and exercise regulations.ResultsUsing mediation procedures, the results showed that the owner's sense of dog walking responsibility and walking relationship was completely mediated by identified (indirect β = .06; bootstrapped lower CI = .02, bootstrapped higher CI = .17) and intrinsic (β = .05; bootstrapped lower CI = .01, bootstrapped higher CI = .15) regulations but these regulations could not account for substantial variance in the dog-related factors. Instead, intrinsic regulation (β = .27), identified regulation (β = .20), dog size (β = .22), and energy level of the dog (β = .13) all contributed to explain 30% of walking behavior.ConclusionA sense of responsibility to walk the dog, generally the most reliable correlate in past dog walking research, appears to align with more self-determined forms of motivation than controlled. The findings, however, support the premise that dog walking behavior may be a complex mix of human and dog-related factors. This dog and owner relationship may need consideration for successful future dog walking promotion initiatives.  相似文献

Coprophilia is a rarely discussed phenomenon although not uncommon in psychiatric intensive care units, inpatient learning disability services and on wards for older people. It evokes intense emotional reactions in those who witness and who are exposed to it. This paper gives a definition and a current diagnostic overview of this unusual phenomenon. It sums up the medical and psychoanalytic approaches, then makes an effort to illustrate and evaluates the psychosexual symbolic meaning of coprophilia through the film of Salò, or The 120 Days of Sodom.  相似文献

It is well established that heterosexism shapes identity management practices of sexual minorities in the United States, but we know little about how such social forces shape heterosexual identity management. This exploratory research is focused on heterosexual marking, defined as behaviors interpreted as signifying a heterosexual identity. Using data from 12 focus groups with young adults, we provide an overview of heterosexual marking in a northeastern United States context and explain how three social forces—cultural assumptions of heterosexuality, sexual orientation ambiguity and suspicion, and heterosexism—are intertwined with these identity practices. Results indicated that this social context generates heterosexual marking that is sometimes intentional and conscious but at other times unintentional and unconscious, depending on levels of heteronormativity and heterosexism.  相似文献

We examined how verbal disclosure affects subjective well-being among gay Latino and White men. In Study 1, increased gay identification predicted increased verbal disclosure for gay White men but not for gay Latino men, who reported verbal disclosure levels in line with a tacit coming out strategy (expressing one’s sexual orientation to others more non-verbally) regardless of their gay identification. Moreover, low verbal disclosure hindered subjective well-being only for gay White men. In Study 2, we show that increased intrinsic self-expression and higher relational self-construal explained the positive relationship between verbal disclosure and well-being among gay White men. This mediational model did not hold for gay Latino men. We discuss verbal disclosure in relation to mainstream understandings of coming out.  相似文献

Evidence suggests that physical inactivity is prevalent among young children. To combat this, one recommendation for caregivers is to become actively involved in their child's physical activities. However, this general recommendation does not specify how or when a parent should become involved. The purpose of the current study was to conduct a functional analysis to identify a social consequence that would increase the moderate‐to‐vigorous physical activity (MVPA) exhibited by preschool‐aged children, and then to compare the effects of that social consequence when it was provided contingent on MVPA and when provided independent of MVPA. The results of the functional analyses indicated that 3 of 7 children were most active when attention or interactive play was provided contingent on MVPA. Results of the intervention analysis suggested that caregivers of young children should provide attention or interactive play contingent on MVPA when those consequences are identified as reinforcers in a functional analysis.  相似文献
