This research advances a novel approach to promoting physical activity, based on the principle of functional matching in persuasion, and the self-concordance (SC) of people's motivations for physical activity. We propose that SC establishes a positive or negative orientation toward the challenge inherent in physical activity, and that the maximum yield of participation will be achieved by communications that appeal to each orientation. In two studies, we compared how messages emphasizing challenge versus available social support would influence recipients’ self-reported practices of physical activity and attitudes toward a physical activity setting. As hypothesized, these messages had differential effects for recipients whose pursuit of physical activity varied in SC, such that favorable outcomes were more reliably associated with challenge-oriented messages among respondents higher in SC versus support-oriented messages among respondents lower in SC. The findings suggest the merits of using self-regulatory, compared with object- or personality-based, constructs and measures to indicate psychological functions of ongoing health-related behaviors.  相似文献

The majority of individuals in the UK with severe haemophilia treat themselves at home with clotting factor. The aim of this study was to examine patient's beliefs about their haemophilia, their beliefs regarding treatment with clotting factor and to assess whether relationships existed between these factors and adherence to home treatment. Patient beliefs were assessed by posting individuals with severe haemophilia A and B ( n = 104) the Illness Perceptions Questionnaire (IPQ) and the Beliefs about Medicines Questionnaire (BMQ). The final analysis was based on 65 questionnaires yielding a response rate of 63%. Adherence to the frequency and to the amount of each clotting factor dose was assessed for individuals treating prophylactically and the amount of each clotting factor dose for those only treating 'on-demand'. Adherence scores were calculated by comparing individual patient treatment records with recommended regimens. Regression analysis indicated that perceptions of illness identity and treatment necessity explained a significant amount of the variance in adherence to frequency of prophylactic infusions and that illness identity was associated with the adherence to the amount of each prophylactic dose. Further regression analysis also showed that the amount of each dose of clotting factor administered on-demand was associated with perceptions regarding the necessity of treatment. Analysis with a combined measure of adherence to dose amount indicated that patients treating on-demand or with prophylaxis who under treated, recorded significantly lower perceptions of illness consequence than individuals who were fully adherent or who over-treated. The results suggest that assessing illness perceptions, especially beliefs regarding identity , consequence and necessity of treatment, may play a valuable role in identifying which individuals are least likely to adhere to treatment.  相似文献

Kelly Trogdon [2009] argues that priority monism—here, the view that only the world as a whole has fundamental properties—conflicts with the best extant accounts of intrinsicality. He then proposes an alternative account that is designed to be not only compatible with this view, but also independently plausible. But his account conflicts with priority monism as well, and incorrectly classifies various non-intrinsic properties.  相似文献

The paradox of hedonism is the idea that making pleasure the only thing that we desire for its own sake can be self-defeating. Why would this be true? In this paper, I survey two prominent explanations, then develop a third possible explanation, inspired by Joseph Butler's classic discussion of the paradox. The existing accounts claim that the paradox arises because we are systematically incompetent at predicting what will make us happy, or because the greatest pleasures for human beings are found in certain special goods which hedonists cannot enjoy. On the account that I develop, the paradox is a consequence of a theory about the nature of pleasure, together with a view about the requirements of rational belief. Which of these explanations is correct, I argue, bears on central questions about how to understand the nature and extent of the paradox.  相似文献

According to some philosophers who accept a propositional conception of evidence, someone's evidence includes a proposition only if it is true. I argue against this thesis by appealing to the possibility of knowledge from falsehood.  相似文献

The study used a post-modern group assessment procedure to explore career perceptions of 11 Grade 11 learners (6= males; 5= females; mean age = 17 years) from disadvantaged communities. A qualitative process of thematic content analysis was used to analyse the data. The results suggest that narrative career assessment in a group setting may provide a viable alternative to career counselling and assessment with disadvantaged learners.  相似文献

The study investigated perceived parental involvement in career development amongst disadvantaged adolescents. Participants were 14 Grade 9 learners (8 boys and 6 girls: mean age =14 years) from a disadvantaged community in North-West Province in South Africa. Data were collected using semi-structured interviews, and analyzed thematically. Perceived constructive verbal persuasion or encouragement was influential in parents' facilitation of career development in their adolescent children. One-way communication from the parents to the adolescents was perceived to be non-supportive of their career development. Vicarious learning was manifested in the adoption of well-known people as role models in the absence of parental role models.  相似文献

Young adult cancer survivors (YACS) face unique challenges from their disease and treatments that may influence their sport participation choices as well as their psychosocial response.ObjectivesTo examine the prevalence, correlates, and psychosocial outcomes of sport participation in YACS.DesignA provincial, population-based mailed survey of 588 YACS in Alberta, Canada, was completed in May 2008 and included measures of sport participation, psychosocial health (depression, self-esteem, and stress), quality of life (QoL), and medical and demographic variables.ResultsOne third (32.5%) of YACS reported participating in a sport in the past month with the most common being golf (40.8%) and ice hockey (8.3%). YACS participating in sport reported an average frequency of 1.7 (SD = 1.0) days/week and an average duration of 119 min/session (SD = 68) for a total of 189 (SD = 164) min/week. Independent t-tests showed that YACS who participated in sport reported better psychosocial health and QoL including physical QoL (p < 0.001), mental QoL (p < 0.001), self-esteem (p < 0.001), depression (p < 0.001), and stress (p < 0.001). In multivariate regression analysis, 8.5% (p < 0.001) of the variance in sport participation was explained by being male (β = 0.17, p < 0.001), Caucasian (β = 0.15, p = 0.001), in better general health (β = 0.15, p < 0.001), and having a normal body mass index (β = ?0.10, p = 0.024).Discussion/conclusionsSport participation is associated with better psychosocial health and QoL in YACS but only a third participated in the past month. Randomized controlled trials examining sport as an intervention strategy to increase physical activity and improve health outcomes in YACS are warranted.  相似文献

In this paper, I explore briefly the "secular priesthood" metaphor often applied to bioethicists. I next ask: if, despite our discomfort with the metaphor, we were to embrace the best aspects of the priesthood(s) – which I identify as the missionaries' willingness to work among sinners and lepers, at their own peril – would we be able to live up to that standard of bravery? I then draw a parallel with the fears of contagion currently be voiced (by Carl Elliott and others), with regard to bioethicists working in or near corporate settings. I argue that such fears may themselves have a number of deleterious effects, and I suggest several possible positive steps in response to that fear.  相似文献

Attributions are constantly assigned in everyday life. A well-known phenomenon is the self-serving bias: that is, people’s tendency to attribute positive events to internal causes (themselves) and negative events to external causes (other persons/circumstances). Here, we investigated the neural correlates of the cognitive processes implicated in self-serving attributions using social situations that differed in their emotional saliences. We administered an attributional bias task during fMRI scanning in a large sample of healthy subjects (n = 71). Eighty sentences describing positive or negative social situations were presented, and subjects decided via buttonpress whether the situation had been caused by themselves or by the other person involved. Comparing positive with negative sentences revealed activations of the bilateral posterior cingulate cortex (PCC). Self-attribution correlated with activation of the posterior portion of the precuneus. However, self-attributed positive versus negative sentences showed activation of the anterior portion of the precuneus, and self-attributed negative versus positive sentences demonstrated activation of the bilateral insular cortex. All significant activations were reported with a statistical threshold of p ≤ .001, uncorrected. In addition, a comparison of our fMRI task with data from the Internal, Personal and Situational Attributions Questionnaire, Revised German Version, demonstrated convergent validity. Our findings suggest that the precuneus and the PCC are involved in the evaluation of social events with particular regional specificities: The PCC is activated during emotional evaluation, the posterior precuneus during attributional evaluation, and the anterior precuneus during self-serving processes. Furthermore, we assume that insula activation is a correlate of awareness of personal agency in negative situations.  相似文献
