Dietary supplement use has increased significantly over the past decade. The use of supplements among adolescents seems to be influenced by their beliefs and attitudes. The influence of coaches, parents, and athletic trainers also may be important. The purpose of this study was (1) to determine whether attitudes are a better predictor of adolescents' intentions to use dietary supplements than are subjective norms, and (2) to assess the influence of significant others (coaches, parents, and trainers) on attitudes, subjective norms, and intentions among adolescent athletes. Adolescents (N = 1,626) who were enrolled in grades six through twelve in nine public schools completed a self-report questionnaire that measured attitudes, subjective norms, and intentions regarding dietary supplement use. Results indicated that attitudes were a better predictor of intentions to use dietary supplements than were subjective norms. It was also found that trainers had more influence on the attitudes, subjective norms, and intentions of adolescents regarding supplement use than did parents and coaches. Implications for prevention are addressed.  相似文献

In this study, we sought to identify cognitive predictors of individual differences in adult foreign-language learning and to test whether metalinguistic awareness mediated the observed relationships. Using a miniature language-learning paradigm, adults (N = 77) learned Russian vocabulary and grammar (gender agreement and case marking) over six 1-h sessions, completing tasks that encouraged attention to phrases without explicitly teaching grammatical rules. The participants’ ability to describe the Russian gender and case-marking patterns mediated the effects of nonverbal intelligence and auditory sequence learning on grammar learning and generalization. Hence, even under implicit-learning conditions, individual differences stemmed from explicit metalinguistic awareness of the underlying grammar, which, in turn, was linked to nonverbal intelligence and auditory sequence learning. Prior knowledge of languages with grammatical gender (predominantly Spanish) predicted learning of gender agreement. Transfer of knowledge of gender from other languages to Russian was not mediated by awareness, which suggests that transfer operates through an implicit process akin to structural priming.  相似文献

There is strong research evidence for the association of personality pathology and posttraumatic stress disorder (PTSD), as well as trauma-related negative cognitions (TRNC) and PTSD symptoms. However, the relationship between personality pathology and TRNC in the context of PTSD is mostly unknown. In the present study, we aimed to examine whether avoidant and borderline personality beliefs (PB, indicator of personality pathology) could predict therapy outcome in PTSD, and whether the relationship between PB and therapy outcome could be mediated by TRNC. Sixty patients with PTSD were assessed for PB, TRNC and PTSD symptoms at baseline, and for PTSD symptoms at the termination of Prolonged Exposure Therapy. Baseline avoidant PB predicted significant variance in PTSD symptoms at termination over and above baseline PTSD symptoms (16% reduction in treatment effect per SD on avoidant PB). Moreover, TRNC at baseline fully mediated the relationships between baseline avoidant PB and PTSD symptoms at termination. This is the first study to show that avoidant PB predicts treatment response in PTSD, and that patients with avoidant beliefs are more vulnerable to have TRNC, which are associated with impeded therapy response. Our results highlight the importance of targeting both dysfunctional PB and TRNC in PTSD interventions.  相似文献

This study explored the bush fire disaster experiences and coping of South African farmers. Participants consisted of seven male farmers (6?=?White Afrikaans-speaking; 1?=?Black Tswana-speaking). Data were collected using semi-structured interviews, nine months after the disaster, and analysed thematically. The findings showed that the farmers’ recovery was characterised by three distinct, transitioning phases. The first period involved resource-maintenance coping and emotion-focused coping. The second time period was characterised by meaning making related strategies. Finally, the third time period was charactirised by anxiety over reoccurrence and resource-maintenance coping. The results also suggest that successful coping is reliant on the individual's ability to adapt coping strategies continually, in a context-appropriate manner.  相似文献

In this article the development and implementation of the Mmogo-Method? is discussed as a culture-sensitive data collection method. The Mmogo-Method? provides opportunities for social researchers to gain a deeper understanding of the cultural symbolism in which social life is embedded and that informs experiences, perceptions and behaviour. In this method, people create their own data by making visual presentations that reflect contextually grounded symbolic meanings. Theoretical underpinnings of social constructionism, symbolic interactionism and community psychology are discussed and applied as the rationale for the development and implementation of the Mmogo-Method?. Examples of research using the Mmogo-Method? are provided to illustrate its value and various different application possibilities. The Mmogo-Method? attempts to produce community-based knowledge that is gathered and disseminated in a coherent way; thereby contributing to the possibility that indigenous knowledge may form part of national and international discussions.  相似文献

Objective: We examined the independent association between dispositional optimism compared to dispositional pessimism and ideal cardiovascular health (defined by the American Heart Association).

Design: A prospective design with a study sample of 1113 participants aged 24–39 years from the longitudinal Young Finns Study.

Main outcome measures: Ideal cardiovascular health (comprised of seven ideal cardiovascular health metrics) was measured in 2001. The ideal cardiovascular health metrics were reassessed in 2007.

Results: Low pessimism rather than high optimism was a better predictor of ideal cardiovascular health in 2007. When examining the association between optimism and pessimism and the seven ideal cardiovascular health metrics in 2007 (BMI, diet, physical activity, smoking status, blood pressure, total cholesterol and plasma glucose), low pessimism predicted non-smoking status, ideal physical activity and eating a healthy diet, while high optimism was associated with eating a healthy diet.

Conclusion: Our findings suggest that low pessimism rather than high optimism is associated with ideal cardiovascular health, especially with health behaviours such as not smoking, being physically active and eating a healthy diet. Socio-economic status was the potential mediating or confounding factor. Future studies should examine the differential meaning of the optimism/pessimism concepts to further clarify their relation to health outcomes.  相似文献

The need‐to‐belong theory stipulates that social exclusion (i.e., being rejected by peers) impairs the ability to self‐regulate, and experimental studies with adults support this contention, at least on a short‐term basis. Few studies have investigated whether social exclusion affects the development of self‐regulation of children in a more enduring manner. By using data from a community sample of 762 children, we investigated reciprocal relations between social exclusion and self‐regulation from age 4 to age 6. Social exclusion was reported by teachers, whereas self‐regulation was reported by parents. Autoregressive latent cross‐lagged analyses showed that social exclusion predicted impaired development of dispositional self‐regulation and, reciprocally, that poor self‐regulation predicted enhanced social exclusion. In other words, social exclusion undermines children's development of self‐regulation, whereas poor self‐regulation increases the likelihood of exclusion. Results illuminate the applied relevance of the need‐to‐belong theory.  相似文献

In this paper we propose a latent class distance association model for clustering in the predictor space of large contingency tables with a categorical response variable. The rows of such a table are characterized as profiles of a set of explanatory variables, while the columns represent a single outcome variable. In many cases such tables are sparse, with many zero entries, which makes traditional models problematic. By clustering the row profiles into a few specific classes and representing these together with the categories of the response variable in a low‐dimensional Euclidean space using a distance association model, a parsimonious prediction model can be obtained. A generalized EM algorithm is proposed to estimate the model parameters and the adjusted Bayesian information criterion statistic is employed to test the number of mixture components and the dimensionality of the representation. An empirical example highlighting the advantages of the new approach and comparing it with traditional approaches is presented.  相似文献
