Objectives: This study was undertaken to ascertain whether or not the body mass index (BMI) of urban disadvantaged children indirectly affects their health-related quality of life (HRQoL) through weight change desires and depressive symptoms and whether such mediation is conditional upon age and gender.

Design: A total of 255 children aged 7–12 years (50% male) were recruited from 7 schools in urban disadvantaged districts in Ireland using consecutive sampling. A prospective longitudinal design was employed whereby children completed, at two time points, the Kidscreen-27, the Children’s Depression Inventory, and the Health Related Behaviour Questionnaire, and had their BMI measured. The analyses involved multiple-, half-longitudinal- and moderated-mediation.

Results: Results showed that the depressive symptoms of children wanting to change their weight may have lead, in large part, to poorer HRQoL (specifically psychological well-being when considering longitudinal data) rather than weight status per se. The mediation effect of weight change desires occurred regardless of age or gender.

Conclusions: Childhood obesity programmes that traditionally focus on the negatives of obesity and the need to control weight may need to take a more positive approach to health and well-being by, for example promoting intuitive eating, an active lifestyle, body acceptance and good mental health.  相似文献

This study sought to test a model of students’ proactive behaviour to use their strengths and improve their deficits and how this relates with their self-reported perceptions of their fit with a study course and engagement. Participants were 692 first-year students from a higher education institution in South Africa (females=60.3%; blacks=71.3%; mean age=19.71; SD=1.93). They completed measures of strengths use, deficit improvement, perceptions of fit with a study course and engagement. Structural equation modelling was utilised to examine the relationship between students’ strengths use and deficit improvement, perceptions of fit with a study course and student engagement. In addition, the bootstrapping method was used to identify possible mediating effects of fit with a study course. The results indicated that only deficit improvement showed a significant relationship with engagement. Perceptions of fit with a study course mediated the relationship between students’ strengths use and deficit improvement.  相似文献

Universities struggle with students’ low well‐being and high dropout rates. High (compared to low) fit between students’ self‐construal and perceived university norms might help to prevent these problems. A strong dignity self‐construal (i.e., the understanding that one's worth is independent of others) is adaptive if university norms stress independence. The more a university norm is perceived as stressing independence, the better the fit for students with a strong (vs. weak) dignity self‐construal. Thus, if students with a strong dignity self‐construal perceive a university norm as stressing independence, they should develop a greater sense of belonging to the university and, in turn, experience higher well‐being, more motivation, and lower dropout intention. A longitudinal study with two measurement points conducted with students from 18 universities (N = 719) provided support for these predictions. This underlines the relevance of the fit between student and (perceived) school characteristics for the higher education sector.  相似文献

主动工作行为, 作为推动组织与时俱进、健康发展的重要保障, 已成为组织行为研究领域的热点主题。然而, 以往研究在探索追随者主动工作行为的上行影响时, 却出现了悖论: 一些研究发现主动工作行为能激发领导者的积极评价, 另一些研究却指出主动工作行为会招致领导者的负面对待。为解释此矛盾现象, 基于内隐追随理论建构了一个主动工作行为的上行影响模型。该理论模型指出, 领导者的内隐追随信念决定了追随者主动工作行为究竟引发领导者的何种反应。先介绍领导者主动型内隐追随的概念与测量, 然后论证追随者主动工作行为与领导者主动型内隐追随的契合程度对领导者的影响, 在此基础上提出领导者核心情绪(高兴、紧张、沮丧与满足)的中介作用。文章为后续主动工作行为实证研究提供了一个理论分析框架。  相似文献

ObjectiveThe objective of this study was to examine the psychometric properties of a French version of the pictorial scale of Perceived Movement Skill Competence for Young Children (PMSC), which is aligned with the third version of the Test of Gross Motor Development.MethodA sample of 219 French-speaking Canadian children (5 to 12 years old) participated in this study.ResultsResults supported the factor validity and reliability of a 13-item version of the PMSC encompassing two factors (i.e., ball skills and locomotor skills). Subsequent analyses supported the weak, partial strong, and partial strict invariance of responses to the PMSC as a function of sex. Additionally, analyses revealed that boys displayed significantly higher perceived ball skill competence than girls. Results also supported a lack of differential item functioning (DIF) and latent mean differences as a function of body mass index and physical activity/sport involvement, but revealed evidence of DIF and latent mean differences as a function of age. More precisely, these results show that older children displayed significantly: (a) higher scores on the sliding item and lower scores on the kicking item relative to younger children; and (b) lower scores on perceived locomotor skills competence than younger children.ConclusionOverall, results suggest that the French version of the PMSC has acceptable psychometric properties and can be confidently used in research or practice to assess children's perceived movement skill competence.  相似文献

随着组织广泛的信息技术运用、工作强度增加,员工之间面对面的、真诚的社交开始呈下降趋势。职场孤独感成了困扰员工的普遍问题,引起了企业管理实践界高度重视。通过综述已有文献,本文指出过往研究虽揭示了职场孤独感带来的消极影响效应并有效提高了组织对职场孤独问题的关注度,但尚未系统回答“如何预防与应对职场孤独感”。为了引导员工对职场孤独感的科学应对,本文认为有必要将员工视为能动的主角而非被动的承受者,并探讨职场孤独感与员工应对行为的关系,为如何应对职场孤独感提供建设性对策。 除此之外,为了更好地预防与遏制职场孤独感,有必要系统性地探讨职场孤独感的形成原因。综合过往研究,本文发现职场孤独感区别于其他消极情绪的核心在于:职场孤独感源自于高质量职场人际关系的缺失。与此观点对应的是,Wright和Silard (2021)认为当员工实际的职场人际关系未达到预期水平,员工会认为职场人际关系存在缺陷,产生孤独的体验。Wright和Silard (2021)的观点反映了职场孤独感是一种员工未实现期望社交目标而导致的心理体验。循此逻辑,本文采用与目标实现过程相关的调节匹配理论来解释职场孤独感的产生原因和影响机制,为预防和应对职场孤独感提供对策。以调节匹配理论为框架,本项目拟解决三个问题:(1)领导与下属的调节焦点(不)匹配如何通过影响领导成员交换,进而影响职场孤独感;(2)员工与团队的调节焦点(不)匹配如何通过影响团队成员交换,进而影响职场孤独感;(3)员工如何依据不同的团队调节氛围来选择社交应对策略,以及社交应对策略对员工绩效的影响。通过新颖的多项式回归分析与曲面响应分析方法,本文力求重构传统的职场孤独感的研究思路,为职场孤独感的产生机制提供新的研究视角。除此之外,本文首次将调节匹配理论引入职场孤独感的研究,系统性地分析了职场孤独感的产生和应对,呈现了职场孤独感现象在组织中的动态演化的过程与机制。  相似文献

In decision making, people can focus on decisional outcomes (outcome focus), but they can also focus on gaining knowledge about the decisional domain (learning focus). Furthermore, people differ in the strength of their epistemic needs—their preference for developing a rich and accurate understanding of the world. We invoke the regulatory fit theory to predict that higher epistemic needs better fit a learning focus than lower epistemic needs, resulting in a greater increase in valuation of the chosen option when a learning rather than an outcome focus is induced. This general hypothesis was tested and supported in three studies, each focusing on a different proxy to epistemic needs. Thus, individuals experienced greater value when they had lower expertise (Study 1), higher need for assessment (Study 2), and higher need for cognition (Study 3) when a learning rather than an outcome focus was induced. Implications for work on epistemic needs, regulatory fit theory, and decision‐making practice are discussed. Copyright © 2011 John Wiley & Sons, Ltd.  相似文献

Body dissatisfaction is a common problem among adolescent girls that is linked to serious outcomes, including the development of eating disorders. This study tested to what degree five theorized risk factors (weight-related teasing, thin-ideal internalization, body mass index [BMI], self-esteem, and perfectionism) predicted prospective changes in body dissatisfaction. At baseline, 393 10th and 11th grade girls (M = 15.8 years) completed questionnaires and had their height and weight measured. One year later, 316 participants’ body dissatisfaction was reassessed (80.4% retention). Results suggested that self-esteem was the most potent risk factor, followed by BMI, when used to categorize girls into high- and low-risk groups for body dissatisfaction at follow-up. However, weight-related teasing, thin-ideal internalization, and perfectionism did not prove to be risk factors. These results suggest self-esteem and BMI are relevant variables for helping to identify middle-adolescent girls who may be at risk for subsequent increases in body dissatisfaction.  相似文献

When deciding for whom to vote, voters should select the candidate they expect to best handle issues, all other things equal. A simple heuristic predicted that the candidate who is rated more favorably on a larger number of issues would win the popular vote. This was correct for nine out of ten U.S. presidential elections from 1972 to 2008. We then used simple linear regression to relate the incumbent's relative issue ratings to the actual two‐party popular vote shares. The resulting model yielded out‐of‐sample forecasts that were competitive with those from the Iowa Electronic Markets and established quantitative models. The issue‐index model has implications for political decision makers, as it can help to track campaigns and to decide which issues to focus on. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

Whilst it is accepted that humankind has been responsible for a considerable amount of environmental change, it is only recently that quantitative measures have been devised to express this. Such measures include a habitat index, the ecological footprint and the Living Planet Index. The applications and implications of these measures are discussed along with direct measures of changing atmospheric composition. All indicate that Europe is the most anthropogenically transformed continent and Australasia the least altered. In so far as a population increase of c. 36 per cent is likely to occur in the next 25 years, human induced environmental change is set to continue at a rapid pace. It is likely to be exacerbated by rapid industrialisation in some nations and increasing standards of living. Local, regional and international measures to curb environmental deterioration may temper this to a degree but new technologies e.g. biotechnology, may bring disadvantages as well as advantages.  相似文献
