Perceived control effects on religiosity and quality of life among young adults

The study investigated the mediating role of perceived control in the association between religiosity and quality of life among young adults in south-west Nigeria. Data were collected from a sample of 1 050 young adults (mean age = 29.8, SD = 4.61; female = 38.7%). Regression analysis was utilised to predict quality of life from religiosity, partialling out perceived control. Findings suggest internal religiosity to predict an environmental domain of quality of life through perceived control. Perceived constraints appear to explain the association between internal religiosity and the environmental domain of quality of life.     

Team weigh-ins and self-weighing: Relations to body-related perceptions and disordered eating in collegiate male athletes

ObjectivesIn this study we examined the relation of team weigh-ins and self-weighing frequency on collegiate male athletes' internalization of body ideals, social pressures about weight/body, body satisfaction, dietary intent, negative affect, drive for muscularity, and bulimic symptomatology.Design and methodsWe used a cross-sectional survey design, and collected data electronically from 738 male intercollegiate athletes in the U.S.ResultsAthletes who self-weighed 7 + times per week reported the most pressure to lose weight and be lean and muscular, engaged in muscle-building behaviors most frequently, dieted most often, and had the highest level of bulimic symptomatology. Further, athletes on teams that conducted mandatory weigh-ins (vs. not) engaged in more muscularity behaviors and dietary restriction.ConclusionWeighing, but in particularly that conducted voluntarily, may contribute to an overconcern with appearance, body size/shape, and weight, which in turn can lead to a variety of behaviors related to eating and body change.     

Acute effects of exercise on women with pre-existing body image concerns: A test of potential mediators

The primary purpose of this study was to propose and test a mediation model of changes in physical self-efficacy, physical self-perceptions, and affect as mediators by which a single bout of exercise improves state body image. A secondary purpose was to identify how long improvements in state body image are sustained post-exercise. Sixty university-aged women (19.57 ± 1.37 y) with pre-existing body image concerns, and who exercised regularly, were randomized to perform 30 min of moderate-to-vigorous intensity exercise or quiet reading. State body image, physical self-efficacy, physical self-perceptions and affect were assessed. Mediational analyses revealed self-perceptions of body fatness (95% CI [0.03, 0.44], κ² = 0.13, ab_ps = 0.20) and strength (95% CI [0.15, 0.60], κ² = 0.23, ab_ps = 0.33) mediated improvements in state body image which were sustained at least 20 min post-exercise. These results contribute to the development of a model explaining the effects of exercise on body image and practical recommendations for the use of exercise to improve body image.     

Self‐efficacy or perceived behavioural control: Which influences consumers' physical activity and healthful eating behaviour maintenance?

This research investigated the role of a commercial program, Michelle Bridges 12 Week Body Transformation (MB12WBT), that uses a variety of tools including social support to influence weight management behaviours such as exercising and eating healthfully. The need for research into weight management remains current given obesity rates have continued to increase in recent decades. Weight management is a complex behaviour that for many consumers involves barriers that influence their commitment to continue exercising and eating healthily. The Theory of Planned Behaviour is frequently used to explain, and to a lesser extent predict, behaviours such as physical activity and healthy eating; however, there is much debate as to whether a perceived behavioural control variable or self‐efficacy is the best predictor of behaviour. Structural equation modelling was used to analyse data from a sample of 724 respondents who answered a baseline and three month follow‐up survey. The analysis revealed self‐efficacy and perceived behavioural control were two distinct constructs. Self‐efficacy was a better predictor of behaviour than perceived behavioural control variables as suggested in the original Theory of Planned Behaviour. Furthermore, self‐efficacy had a significant impact on exercising and eating healthfully behaviour. The findings and implications for both behaviour change theory and practice are discussed.     

社交网站使用对体像满意度的影响:体像比较的中介作用和自我客体化的调节作用

为探讨社交网站使用强度对青少年体像满意度的影响和其中的作用机制,采用社交网站使用强度量表、体像比较量表、体像不满量表和自我客体化量表对1469名中学生(736名男生,733名女生)进行研究,结果表明:(1)青少年社交网站使用强度与体像比较显著正相关,与体像满意度显著负相关,女生体像比较与体像满意度显著负相关,男生则不显著。(2)女生社交网站使用通过体像比较的部分中介作用预测体像满意度,且体像比较的中介作用受到自我客体化的调节。研究结果进一步揭示了女生社交网站使用与体像满意度关系的作用机制,有助于指导青少年女生积极健康地进行网络社交活动。     

The Relevance of Self‐Evaluations for Students' Career Optimism

This study investigated how people's beliefs regarding their vocational abilities (i.e., career decision self‐efficacy) are associated with their perceived academic control, self‐liking, and self‐competence. It also assessed the relevance of these 4 types of self‐beliefs for personal job optimism among 268 Croatian college students. Results indicated that participants' career decision self‐efficacy and perceptions of their chances of finding jobs nationwide were significant predictors of personal job optimism. Furthermore, the influences of self‐competence and perceived academic control on personal job optimism were mediated by career decision self‐efficacy. These results extend previous research and may be informative for vocational guidance interventions.     

The Role of Perceived Employability,Core Self-Evaluations,and Job Resources on Health and Turnover Intentions

According to Conservation of Resources (COR) theory, this study investigated the explanatory role of perceived employability, over and above core self-evaluations (CSE) and job resources, in relation to different aspects of health (physical and mental) and turnover intentions. Based on data obtained from a sample of 274 Romanian blue-collar employees (59.5% men), hierarchical multiple regressions revealed that perceived employability adds a significant variance compared to variance due to CSE and job resources with respect to aspects of health and turnover. The results highlight the role of perceived employability in health – on an individual level, and in decisions to leave the organization – on an organizational level. The findings are of value because they inform organizations how to design human resources strategies in order to retain a healthy workforce.     

产品也会皱眉头? 产品的“侵略性表情”对消费者的影响

消费者经常在产品外观设计中看到"表情",这些由企业有意或无意塑造的面孔元素会影响到消费者对产品的态度。当前,关于产品外观表情对消费者态度影响方面的研究仍存在结论不一致、机制不明确和边界不清楚等问题。本研究通过3次分离的实验,验证了对于奢侈程度较高的产品(品牌),侵略性的表情相较友好的表情,更能够获得消费者的青睐;而对于奢侈程度较低的产品(品牌),则恰好相反。同时,不同的产品外观(品牌标识)表情是通过消费者对产品的感知自治程度这一中介变量对消费者态度产生影响。本研究结论为产品外观设计和品牌管理实践提供了有益的建议。     

仁慈领导与员工创新行为:内部人身份感知的中介作用和领导-部属交换关系差异化的调节作用

探究仁慈领导与员工创新行为的关系,以及在该关系中内部人身份感知的中介作用和领导-部属交换关系差异化的调节作用。以68名主管和215名员工为对象,通过对两阶段主管-员工配对调查所获取的数据进行分析,结果表明:(1)仁慈领导可以借助内部人身份感知的中介作用,对员工创新行为产生积极的影响;(2)领导-部属交换关系差异化能调节仁慈领导和内部人身份感知的关系,即当关系差异化水平越高,仁慈领导与内部人身份感知之间的正向关系越强;(3)领导-部属交换关系差异化能调节内部人身份感知在仁慈领导与员工创新行为关系间的中介作用,表现为被调节的中介作用模式,即领导-部属交换关系差异化水平越高,仁慈领导与员工创新行为之间通过内部人身份感知的间接关系越强。
