The platinum mining sector in South Africa presents a significant context for the study of work engagement, given the major changes and turmoil experienced by employees in this sector. The aim of this study was to investigate the effects of task and relational factors on work engagement in the platinum mining industry in South Africa. A stratified random sample (N = 564) comprising employees in a platinum mining organisation in South Africa was surveyed (females = 35.1%, blacks = 51.6%, middle managers = 40.8%). The employees completed a biographical questionnaire and several other measures: the Engagement Scale, Supervisory Support Scale, Social Support Scale and Job Diagnostic Survey. The results supported a reliable three-factor structure (consisting of autonomy support, competence support, and relatedness support) for the Supervisory Support Scale. The structural model confirmed that task characteristics (comprising task significance and task identity) were strongly related to work engagement. Supervisor support and co-worker support showed a positive relationship with work engagement, albeit to a lesser extent.  相似文献

This study explored types and nature of supports by relatives of mothers living with HIV and psychosis in comparison to mothers with HIV only. Interview data on their experiences of their roles, needs and challenges were collected from 33 relatives on mothers with HIV and psychosis (n=12, females=10, blacks =12, age ranges 21 to 62) and those with HIV only (n=21, females=16, blacks =21, age ranges 18 to 63). The data were thematically analysed utilizing Atlas.ti. The results showed that relatives in both groups provided a variety of supporting roles. Important challenges were experiencing the negative consequences of especially HIV in combination with psychosis in their lives and dealing with the caregiving responsibilities without having enough information. Important strengths included utilizing support networks and remaining hopeful. Support needs for carers of mothers living with HIV related psychosis or HIV only, can be enhanced with increasing social and material resources at the community level. Supporting needs can be addressed by empowering communities through psycho-education.  相似文献

Research based in self-determination theory has demonstrated the importance of social agents for motivational processes in school-based physical education (PE). To focus more closely on the relational processes that underpin students’ motivation in PE, there have been calls for researchers to explore the specific teacher behaviors that facilitate students’ relatedness in PE. Our aim was to test a higher-order measurement model comprising distinct relatedness-supportive teacher behaviors, and to explore the ways in which students’ perceptions about their teacher directly and/or indirectly predict relatedness need satisfaction and motivation in PE. To test our higher-order model (Study 1), 656 high-school PE students reported the extent to which their teachers engaged in relatedness-supportive behaviors. In Study 2, 570 high-school PE students reported their motivational regulations for PE, as well as the extent to which their teacher engaged in relatedness-supportive behaviors, and satisfied their need for relatedness. We found support for the higher-order relatedness support model, and observed predictive pathways that were consistent with theory. Students reported satisfaction of their need for relatedness when they felt relatedness support from their teachers (β = 0.52, p < 0.001) and relatedness need satisfaction was in turn positively related to intrinsic (β = 0.51, p < 0.001), identified (β = 0.49, p < 0.001), and introjected (β = 0.25, p < 0.001) regulations for PE. These findings demonstrate the importance of relatedness-supportive teaching in PE, and implications of these data are discussed.  相似文献

ObjectiveTo test a model of Social Cognitive Theory variables for predicting participation in higher versus lower levels of parasport competition. Information on modifiable factors associated with parasport competition would help parasport coaches and organizations transition recreational and developmental-level athletes to more competitive streams of participation.DesignCross-sectional survey.MethodParticipants were 95 parasport athletes with physical disabilities that cause mobility impairment (74% male; mean age = 34.36 ± 12.41). Measures of Social Cognitive Theory constructs were assessed via online questionnaires. Path analysis was used to test the proposed model.ResultsThe model explained 12% of the variance in level of sport participation. Peer support for sport was a significant predictor of self-regulatory efficacy (β = .22, p < .05) which, in turn, was positively related to outcome expectations (β = .43, p < .001), and self-regulation (β = .43, p < .001). Self-regulatory efficacy was the only significant predictor of level of sport participation (β = .26, p < .05). There were no significant indirect effects between social support and competitive status (p > .05).DiscussionSocial Cognitive Theory provides a reasonable basis for formulating a model of psychosocial factors related to parasport competitive status. Other relevant factors should be taken into consideration in subsequent studies. Parasport coaches and organizations may benefit from leveraging peer support to help bolster athletes' self-regulatory efficacy to levels conducive to participation in higher competitive sport streams.  相似文献

Politicians’ desire for reelection motivates them to be responsive to voters’ policy preferences. In the traditional view, voters choose between candidates based on their delivery of favorable outcomes such as ideologically appealing policies or a prospering economy. However, research in psychology shows that, in addition to outcomes, people care about procedural fairness and, particularly, impartial decision‐makers who make decisions without personal motives and interests. This, I argue, confronts politicians with a delicate task: politicians must present voters with favorable policy outcomes but without appearing as if they pursue these policies based on a personal, vote‐maximizing motive for reelection. In four survey experiments, I find support for this argument. Participants were significantly less inclined to trust and vote for politicians and support their policies when political decisions were described as motivated by reelection considerations than when no such motive was present. The findings advance our understanding of how citizens view political representation and have important implications for research on public opinion, legislative behavior, and democratic theory.  相似文献

University support services can be a beneficial resource for students coping with personal stressors. This study investigated the predictors of service use by undergraduate students during their first year at university. Participants completed self-report measures of problem-solving effectiveness, psychological distress and perceived social support (availability and satisfaction) at the start of the academic year, frequency of exposure to stressors half-way through the first semester and support service use at the end of the first and second semesters. Perceived availability of social support and frequency of exposure to stressors predicted service use. Additional analyses examined change in psychological distress across the first semester. Implications of these findings are discussed.  相似文献

Previous studies have shown that depression is negatively associated with hope and social support. However, little research has been undertaken to investigate the theoretical mechanisms underlying the connections among hope, social support, and depression. This study examined how two types of self-esteem (personal and relational) would mediate the relationship of hope and social support to depression among 384 Hong Kong adolescents (age: 12–18 years; M = 14, SD = 1.19). Participants reported their levels of hope, social support, personal self-esteem, relational self-esteem, and depressive mood. Results of the path analysis showed that both personal and relational self-esteem mediated the associations of hope and social support with depression. Hope and social support were associated with higher levels of personal and relational self-esteem, which were in turn related to decreased levels of depression. Theoretical and practical implications are discussed.  相似文献

Vulnerable youth have fewer social ties as a result of inadequate housing and a lack of social support. It is well established that many of these youth tend to underutilize mental health, medical, and social services. Among marginalized and stigmatized populations, the affirming and nonjudgmental presence of companion animals appears to be important for developing collaborative relationships between youth and professional service providers. This paper reviews literature on the benefits of companion animals for assisting providers in their attempts to help youth find a stable living environment. Recommendations are made for providers considering incorporating therapy animals into their existing services.  相似文献
