Objective: Perceived variety represents a psychosocial experience that gives rise to, and supports the maintenance of, an individual’s well-being. In this study, we developed an instrument to measure perceived variety in exercise (PVE), and examined whether ratings of PVE predict unique variance in indices of exercise-related well-being in addition to that explained by satisfaction of the three basic psychological needs (for competence, relatedness and autonomy) embedded within self-determination theory (SDT). We also examined the extent to which variance in perceived variety is empirically distinct from (or subsumed by) competence, relatedness and autonomy in the context of exercise.Methods: A convenience sample of community adults (N?=?507) completed online surveys twice over a six-week period (n?=?367).Results: PVE was found to prospectively predict unique variance in indices of exercise-related well-being, in addition to that explained by perceived competence, relatedness and autonomy. Using exploratory and confirmatory factor analytic procedures, perceived variety was found to be empirically distinct from perceived competence, relatedness and autonomy.Conclusion: Results from this work suggest that perceived variety holds potential for theoretical and applied advancements in understanding and predicting well-being in exercise settings. 相似文献

Objective: To change implicit and explicit bias so that active obese people are regarded as more fit and normal weight sedentary people as less fit.Design: Study one created a questionnaire that measured perceptions of active obese persons and sedentary normal weight persons on fitness-related items. Study two used a modified visual probe task to retrain perceptions regarding active obese persons and sedentary normal weight persons.Main outcome measures: Self-reported explicit bias was measured with a questionnaire and implicit bias was measured with response times collected during a visual probe task.Results: The questionnaire reliably measured ‘fitness and fatness’ perceptions. In study two, pairing images of active obese persons with positive activity-related words resulted in active obese persons being explicitly rated more fit; pairing images of normal weight sedentary persons with negative words associated with sedentary lifestyles increased endorsement of normal weight people as unfit. There were no changes in implicit bias.Conclusions: Bias regarding how body weight is thought of relative to fitness can be altered by pairing images of obese persons being active with words such as ‘health’ and ‘fit’. This is evidence that representations of persons of all body weight should be used when promoting physical activity. 相似文献

AbstractObjectives: To examine within-person and between-person sources of variation in the relationship between physical activity and cognition in older adults participating in a walking program. To explore whether demographic, health and fitness variables, and their interactions with activity, are significant predictors of cognition.Design: Brief longitudinal burst design.Participants: 118 participants (91 females, mean age?=?72.81?+ 5.24 years).Main Outcome Measures: Cognition, self-reported moderate-to-vigorous walking and self-reported moderate-to-vigorous physical activity were assessed at baseline and 6, 9, 12 and 16 weeks follow-up. Attendance at weekly walks was also recorded.Results: Within-persons, changes in physical activity were related to select measures of executive functioning, with increased activity predictive of better cognition (three of four cognitive functions, p<.05). Between-persons, activity was also associated with cognition (two of four cognitive functions, p<.05). Younger age and higher education were related to better cognition. Interactions of demographic, health, and fitness variables with changes in within-person activity were generally non-significant.Conclusion: The results highlight the importance of distinguishing within- from between-person effects in longitudinal analyses of the association between physical activity and cognition. This stringent within-person test of association underscores the potential value of simple physical activity interventions for improving cognitive function. 相似文献

Gender differences in lifestyle-related mortality and morbidity suggest a need to investigate gender-specificity of health behaviour change process and factors influencing it. We tested whether changes in self-efficacy beliefs and planning, as well as the level of social support predict change in exercise. Finnish men and women, aged 50–65 years, at an increased risk for type 2 diabetes were recruited from health care centres to participate in the Good Ageing in Lahti Region (GOAL) Lifestyle Implementation Trial. Psychosocial factors were measured with questionnaires and exercise with 7-day physical activity diaries at baseline and at 3 months. At baseline, no gender differences were found in self-efficacy and planning, but men reported receiving more social support than women. At 3 months, women reported having formed more action plans for changing their exercise routines than men. Among women, increase in self-efficacy and planning predicted increase in exercise. Among men, changes in planning played a less significant role. The more salient role of planning for women than for men, and the fact that women receive less social support, may reflect life circumstances allowing less spontaneous lifestyle decisions and a lower acceptance of lifestyle changes by their social environment. 相似文献

Past studies have found that risk perceptions of suffering from diseases play an important role in the development of intentions to perform physical activity (PA). According to the behaviour motivation hypothesis, perceived risk could be positively and directly related to PA, but this possibility has been ignored and/or underestimated. Accounting for recent methodological developments on the importance of study design and risk perception assessment, the purpose of the present study was to examine the risk-perceptions–PA relationship among older adults. Participants (N?=?143) aged from 61 to 70 years initially underwent measurement of risk perceptions, baseline PA, socio-demographic and health factors. Six months later, they were asked about their PA participation. Multiple regression analyses revealed that perceived risk of suffering from diseases and conditions without regular PA participation was an independent positive predictor of later PA, over and beyond baseline behaviour, socio-demographic and health variables. This study fills a gap in the existing literature on the PAs of older adults and reveals that risk perceptions are directly linked to their participation. In addition, it extends existing knowledge in health psychology on the behaviour motivation hypothesis, and emphasises the necessity of methodological adjustments when assessing the risk-perception–behaviour relationship. 相似文献

Abstract This study examined the relationships between achievement goals, beliefs about sport success and sport emotions with moderate to vigorous physical activity of Estonian adolescents. Three hundred and seventy five adolescents, aged 13–14 years, completed the Task and Ego Orientation in Sport Questionnaire and 7-day physical activity recall. Measures of the adolescent's orientation to work avoidance, focus on cooperation, beliefs about the causes of success and degree of satisfaction/interest specific to the context of sport and games were also included. Moderate to vigorous physical activity (MVPA) quartiles were determined and psychological measures for extreme activity groups were compared. A one-way ANOVA indicated that active males scored significantly higher in task orientation, motivation/effort, ability and enjoyment/interest whereas active females showed higher scores for cooperation and exercise enjoyment and lower deception and boredom compared with low activity groups. Correlation analysis revealed that in males, MVPA was related with task orientation, reported ability and motivation/ effort. For females, cooperation, and enjoyment of sport were positively and the amount of boredom was negatively associated with MVPA scores. Multiple regression analysis revealed that psychological measures explained only 14% (females) and 19% (males) of the variance in MVPA. It is concluded that for adolescent males and females, different psychological measures predicted MVPA behavior. 相似文献

Abstract This study investigated the validity of a Stages of Change algorithm with respect to independent measures of physical activity and fitness. dietary intake and alcohol consumption in 18 year-old Ausmlian men (n = 301) and women (n = 282). Stage of Change categories were related to fat and fibre intakes in men and fibre intake in women as well as hit and vegetable intakes in men and women. Physical activity and fitness for men and women also showed significant linear associations with Stage of Change categories. Alcohol consumption was significantly associated with Stage of Change categories for men but not for women although recorded alcohol consumption was very variable for women. However, the algorithm was valid for both men and women when drinking alcohol consistent with national guidelines on safe drinking was used. In summary, with reference to actual health behaviours, the Stages of Change algorithm was valid for young men and women for diet. physical activity and alcohol drinking. Independent behavioural data were not available for smoking behaviours. Using the algorithm, there were significant associations in men between prccontemplation status for diet and drinking and diet and physical activity, in women between diet and smoking and in both men and women between drinking and smoking. Covariance between precontemplation status for different health behaviours therefore suggests the need for multimodal interventions. 相似文献

Abstract The perception of behaviours from two categories of health enhancing physical activity (HEPA): outdoor aerobic exercise (OAE) and everyday commuting activity (ECA) was examined in a sample of middle-aged persons (N= 50). A focused semi-standardised interview was constructed on the bases of the components of the Theory of Planned Behaviour (TPB). The participants perceived OAE behaviours predominantly from the viewpoint of exercise and those of the ECA from that of the fluency of daily routines. They considered the OAE as sensible and associated it with positive health or fitness outcomes, but only those practising it also attributed positive psychological effects to OAE behaviours. A slightly better congruence with the TPB was found for the OAE behaviours than for those of the ECA. The difference is discussed in the light of the higher degree of decisional control with the OAE behaviours and the greater psychological heterogeneity of the ECA. 相似文献

This paper elicited context specific underlying beliefs for physical activity, fruit and vegetable consumption and smoke-free behaviour from the Theory of Planned Behaviour (TPB), and then determined whether the TPB explained significant variation in intentions and behaviour over a 1 month period in a sample of grade 7–9 (age 12–16 years) adolescents. Eighteen individual interviews and one focus group were used to elicit student beliefs. Analyses of this data produced behavioural, normative and control beliefs which were put into a TPB questionnaire completed by 183 students at time 1 and time 2. The Path analyses from the main study showed that the attitude/intention relationship was moderately large for fruit and vegetable consumption and small to moderate for being smoke free. Perceived behavioural control had a large effect on being smoke free and a moderately large effect for fruit and vegetable consumption and physical activity. Intention had a large direct effect on all three behaviours. Common (e.g. feel better, more energy) and behaviour-specific (e.g., prevent yellow fingers, control my weight) beliefs emerged across the three health behaviours. These novel findings, to the adolescent population, support the importance of specific attention being given to each of the behaviours in future multi-behavioural interventions. 相似文献

Abstract This study investigated whether measures of three perceived control (PC) concepts tapped independent dimensions, were invariant to population characteristics of health and culture, were differentially sensitive to health outcomes, and were discriminable from self-report disability. The Multidimensional Health Locus of Control, Generalized Self-efficacy, and Perceived Health Competence (PHC) Scales were administered to 106 Scottish students and 145 Scottish, Spanish and Irish patients, who also completed versions of the Sickness Impact Profile. Principal Components analyses revealed five factors reflecting scale constructions for students and six factors for patients, as PHC items fell on two factors. Disability items fell on a separate factor from all PC items. Results suggest: (a) PC is multidimensional regardless of health and culture; (b) adequate assessment requires multiple PC measures; and (c) it is meaningful to consider PC as a possible influence on disability. 相似文献
