ObjectiveThis research project aimed to explore the construct validity of the Decision-Specific Reinvestment Scale (DSRS); more specifically, its links with stress and coping appraisals.DesignStudy 1 validated the DSRS and the Movement-Specific Reinvestment Scale (MSRS) to the French language, in order to examine the construct validity of the DSRS using the MSRS, the Preference for Intuition and Deliberation (PID) inventory and the Melbourne Decision-Making Questionnaire (MDMQ). In addition, sex differences in reinvestment were investigated. Study 2 examined stress and coping appraisals of high and low reinvesters.MethodIn study 1, 379 athletes completed the DSRS, MSRS, PID, and MDMQ. In study 2, 100 handball players, classified as low and high reinvesters, completed surveys aimed to assess stressor intensity, stressor perceived controllability, coping effectiveness, subjective performance and coping strategies with the Coping Inventory for Competitive Sport over three games.ResultsIn study 1, we found that intuitive athletes scored lower on the DSRS in comparison to deliberative athletes, whilst no difference was found for the MSRS. Convergent and discriminant validity was illustrated with the subscales of the MDMQ. No sex differences were found regarding reinvestment. In study 2, findings showed that low reinvesters scored higher than high reinvesters in terms of stressor perceived controllability, coping effectiveness and subjective performance.DiscussionIn addition to confirmation of construct validity, these findings strengthen our understanding of how high decision reinvesters perceive a pressured situation. Key applications are derived from our findings informing coaches and athletes in offsetting the negative effects of reinvestment on sport performance.  相似文献

IntroductionSo far, no qualitative content analysis (QCA) has analysed pilots’ experiences and perceptions regarding weaknesses of fatigue risk management (FRM), flight time limitations (FTL), rosters, fatigue-severity, sleep problems, and how they relate to pilots’ mental health and well-being.ObjectiveThis research analyses pilots’ described perceptions of stress, fatigue, aviation safety and how regulations like FTL can affect their health and well-being.MethodIn total, 119 international pilots described their perceptions of FTL, rosters, aviation safety, and how they relate to fatigue and health. The QCA was conducted to analyse interactions of working conditions, stressors, fatigue, sleep problems and mental health of EASA-based and Australian pilots.ResultsAlthough pilots were rostered for only 60.8% to 62.5% of the legally allowed duty and flight hours/month, 78.6% reported severe or very high fatigue, 22.8% significant depression, 12.3% significant anxiety symptoms, 10.5% reported significant depression and anxiety symptoms. Pilots uttered severe concerns about FTL, sleep restrictions associated with early starts, minimum rest, etc. Pilots also expressed distinct fears regarding more fatigue-related crashes, and how adverse working conditions, work-related and psychosocial stress could impair their health.ConclusionsThis QCA provided valuable insights into interactions of working conditions, fatigue, sleep restrictions, physical and mental health. Progressive health impairment due to lack of sleep and accumulated fatigue promote burnout, mental and physical health problems, which not only threaten flight safety, but also sustainability of aviation.  相似文献

For most individuals, perfectionistic strivings and perfectionistic concerns coexist to varying degrees. While there is agreement that within-person combinations of perfectionistic strivings and perfectionistic concerns produce meaningful “subtypes”, the number and characterization of these within-person combinations is still debated. The two most prominent person-centered perfectionism models (the tripartite model and the 2 × 2 model) offer differing characterizations of how perfectionistic strivings effects perfectionistic concerns’ relationship with psychological outcomes. According to the 2 × 2 model, perfectionistic strivings buffers against the negative effects of perfectionistic concerns. The 2 × 2 model thus claims the most deleterious within-person combination of perfectionistic strivings and perfectionistic concerns is low strivings and high concerns. In contrast, according to the tripartite model, perfectionistic strivings exacerbates the maladaptive effects of perfectionistic concerns. The tripartite model thus claims the most maladaptive within-person combination of perfectionistic strivings and perfectionistic concerns is high strivings and high concerns. The present study tested these competing claims in a group of English speaking Canadians and a group of Mandarin speaking Chinese. Results support the tripartite model of perfectionism.  相似文献

A proportion of 55 % of school administrators experience a high level of job stress mainly caused by relationship conflicts and overwork. According to the demands and resources of employment model, having personal resources would protect against the harmful effect of the difficulties experienced and the more specific a resource, the more it can counter the effect. Thus, political skills (HP) would decrease the effect of demands related to relationship conflicts, while the sense of self-efficacy (PES) decreases the negative impact of the workload on the PES. The objective of this study is to verify the effect of personal resources, HP and MS, on the relationship between job demands and job psychological health. A total of 232 school administrators from Quebec participated in the study. Job demands, as well as personal resources, are linked to anxiety and serenity according to Bakker and Demerouti (2007). Nevertheless, the SEP does not interact with the relationship of demands and psychological health in employment (PES). In addition, only the social astuteness dimension of HP moderates the relationship of demands and anxiety.  相似文献

The COVID-19 pandemic resulted in social-distancing measures and the suspension of organised sport globally, and has been shown to have negatively impacted mental health. However, athletes may have experienced reprieve from sport demands, which have previously been linked with maladaptive responses such as burnout and stress. The aims of this study were (1) compare levels of burnout and stress reported by Gaelic games athletes pre- and post-COVID-19 suspension period, (2) explore how athletes utilised and perceived this period and the return to sport, and (3) examine the implications of this for burnout. Participants completed an online questionnaire, which included the athlete burnout questionnaire, perceived stress scale, sport emotion questionnaire, demographic questions, weekly training hours, and other hours for sport (e.g. travel) before Covid-19 (BC-19) and after the Covid-19-induced suspension (AC-19_S). Questions relating to how athletes utilised (e.g. training focus) and perceived (positive/negative impact) the period were included AC-19 S. Data was compared across time-points and we explored predictors of burnout AC-19_S. Ninety-two athletes completed the questionnaire at both time-points. No significant differences in burnout or stress were identified, suggesting the suspension period did not significantly impact these variables. Burnout BC-19, stress AC-19_S, unpleasant emotions about returning to sport and using the period to rest/recover positively predicted burnout AC-19_S. Reduction in other hours across time-points and pleasant emotions about returning predicted lower burnout. Results suggest an athletes’ response to a suspension period and subsequent return to sport can impact feelings of burnout, and may have implications for future unanticipated change events.  相似文献

Understanding perceptions of safety and comfort (PSC) while walking or cycling is essential to accommodating and encouraging active travel, but current measures of PSC, primarily surveys, suffer from validity and reliability issues. Physiological markers of stress like electrodermal activity and heart rate variability have been proposed as alternative, objective measures of PSC. This paper presents a literature summary and conceptual framework examining the use of physiological stress markers during walking and cycling. The existing studies of active traveller stress markers report inconsistent findings and account for limited controls. We propose a comprehensive conceptual framework to describe the array of dynamic stimuli experienced during active travel, with complex appraisals and multidimensional stress responses that feedback to travel behaviour and stimuli exposure, and culminate in a set of physiological outcomes triggered by activation of the autonomic nervous system – all moderated by numerous personal and trip-related factors. The key challenge of inferring traffic-related fear or discomfort from physiological markers measured on-road is potential confounding effects of: (1) non-traffic factors that induce or modify stress responses, (2) traffic factors that induce stress responses not associated with safety or comfort, and (3) personal and environmental factors that directly influence physiological measurements outside of a stress response. No physiological stress marker has yet been shown to be reliable for on-road active travellers, particularly not for inter-subject comparisons. Physiological markers have the potential to provide high-resolution, objective information about pedestrian and cyclist PSC, but further research, particularly controlled experiments, and more precise study framing are needed to ensure validity and address moderating and confounding factors.  相似文献

This study examined the effects of in utero exposure to maternal depression and Superstorm Sandy, a hurricane that hit metropolitan New York in 2012, on infant temperament at 6 months. Temperament was assessed using the Infant Behavior Questionnaire-Revised. Maternal depression was measured by the Edinburgh Postnatal Depression Scale. The main effects and the interaction of maternal depression and Sandy exposure on infant temperament were examined using a multivariable generalized linear model. Results show that prenatal maternal depression was associated with lower emotion regulation and greater distress. Stratification and interaction analyses suggested that the adverse effects of prenatal maternal depression on problematic temperament were amplified by in utero Sandy exposure. This study underscores the importance of providing prenatal screening and treatment for maternal depression during pregnancy while also identifying high-risk families who may have suffered from disaster-related traumas to provide necessary services. As the frequency of natural disasters may increase due to climate change, it is important to understand the consequences of in utero stress on child development and to formulate plans for early identification.  相似文献

A worry state is assumed to emerge from the interaction between metacognitive beliefs, and the appraisal of environmental demands (Wells & Matthews, 1994). The aim of this study was to show that metacognitive beliefs moderate the effect of sources of social evaluative threat on worry. Our sample (N = 174) completed a working memory task in two contexts (threatful vs. neutral), while both pre- and post-task measures subjective stress states were recorded. Our results confirmed significant effects of sources of social evaluative threat and metacognitive beliefs on worry. The interaction metacognition * threat context effect on worry was not significant. Our findings support the hypothesis that worry is a form of subjective stress explained by a combination of outcome uncontrollability and social evaluative threat. Social evaluative threat and metacognitive beliefs appeared as two, independent predictors of a worry state. Our results are discussed in reference to the Self Regulative model of stress.  相似文献

Background and Objectives: Stress and stress-related mental health complaints are common and increasing among adolescents, especially girls. Identifying typical sources of stress as well as central intervention targets is an important effort in the development of effective prevention and treatment protocols. This study investigated worry as potential mediator in the development of mental health problems in response to common stressors in adolescence. We also examined to what sources adolescents ascribe their stress over the years from the 7th through the 9th grade.

Design: Prospective cohort study.

Methods: Self-reported subjective stressor load, worry, anxiety and depressive symptoms were assessed in a sample of Swedish 7th graders (N?=?1137; 46% girls, mean age 13.2) with follow-up assessments one and two years later.

Results: School was the most common source of stress across all time-points, with girls reporting considerable more stress than boys. Worry mediated the relationship between overall stressor load and depressive symptoms and anxiety over time and was not moderated by gender.

Conclusions: Worry may be an important target in stress prevention and efforts to prevent stress-related problems would benefit from focusing on early adolescence as especially school stress is already relatively common in grade 7.  相似文献

This study examines the relationships between coping strategies, perceived social support, resilience, PTSD symptoms, and posttraumatic growth (PTG) in a sample of 256 survivors of the 2010 Haiti earthquake. The results of the bivariate analysis suggested a significant positive correlation between PTG and resilience, PTSD symptoms, perceived social support, positive religious coping, and active coping. There was a significant positive relationship between perceived social support and resilience and between resilience and active coping. PTSD symptoms were positively correlated with both positive and negative religious coping. Results of the multiple regression analysis indicated that positive religious coping, active coping, perceived social support, resilience, and PTSD symptoms accounted for 34% of the variance in the participants’ PTG. The strongest predictor of PTG was positive religious coping, followed by active coping, perceived social support, resilience, PTSD symptoms, and negative religious coping. Implications and recommendations for future research were discussed.  相似文献
