Perceived sources and levels of stress,general self-efficacy and coping strategies in preclinical dental students

Dental education programs are known to be highly stressful and stress can affect general health. The aims were to identify sources of stress among preclinical students and to evaluate their perceived levels of stress, self-efficacy and effective coping strategies in a private dental school. One hundred preclinical students in a Turkish private dental school were surveyed using dental environment stress (DES), perceived stress (PSS), general self-efficacy (G-SES) and brief coping scales (Brief-COPE). Age, gender, history of psychiatric treatment, factors that affected the choice of dentistry, choice rank of dental school, scholarship and income was recorded. ‘Exams and grades’ followed by ‘Fear of failing course or year’ were found to be the most stressprovoking factors. The most and the least stressprovoking DES domains were ‘Workload’ and ‘Social stressors’, respectively. ‘Social stressors’ affected male more than female (p < .05). The most and the least common coping strategies were found to be ‘Planning’, and ‘Drug’, respectively. Female used ‘Instrumental support’ more than male (p < .05). Demographic factors had impact on the perceived stress factors and levels, as well as coping strategies. Unlike previous studies establishing high stress levels in dental students, preclinical students displayed moderate level of stress. Clinical dental education might be more responsible for creating stress.     

Virtual Reality and Cognitive-Behavioral Therapy for Driving Anxiety and Aggression in Veterans: A Pilot Study

Within the U.S. military, motor vehicle accidents (MVAs) are the leading cause of preventable morbidity and mortality. Prior combat exposure and anxiety symptoms are associated with risky and aggressive driving, which is responsible for over half of MVA fatalities. Therefore, interventions are needed to reduce driving anxiety and aggression in veterans in order to mitigate the public health impact of MVAs. Virtual reality exposure therapy (VRET) offers safe, controlled exposure to distressing stimuli. The current study piloted a novel virtual reality and cognitive behavioral intervention (VRET + CBT) for veterans that integrated both anxiety and anger management components. Virtual reality driving scenarios were delivered in a driving simulator and tailored for the military population. Six previously deployed veterans completed eight intervention sessions, as well as pre/post, one month follow-up and six to nine month follow-up assessments. Repeated measures ANOVAs demonstrated significant decline and large effect sizes for PTSD symptoms, driving phobia, hyperarousal in driving situations, anxiety/anger-related thoughts and behaviors, and risky driving. Hyperarousal in driving situations declined by 69%, aggressive driving declined by 29%, and risky driving declined by 21%. Treatment gains were maintained at follow-up. Recruitment, retention, immersion, simulator sickness scores, and qualitative feedback demonstrated feasibility of the intervention. Implications for future research and adaptation are discussed.     

Stress perçu et santé physique des doctorants dans les universités françaises

Few studies have focused on PhD students in France despite the fact that this population appears to be particularly vulnerable to stress and often faces precariousness. This research investigated associations between socio-demographic factors, health behaviours, perceived stress and physical health in a wide sample of PhD students (n = 1923) in order to have a better understanding of this population's specificities. Our results indicated that stress is a critical issue among PhD candidates. Predictors of perceived stress were: gender, age, satisfaction with supervision, sleep quality and sports practice. Findings from this study confirm the relevance of the transactional model to investigate students’ health issues and suggest that physical activity and stress management should be encouraged through health promotion programs.     

The physical postures of yoga practices may protect against depressive symptoms,even as life stressors increase: a moderation analysis

Yoga contains sub-components related to its physical postures (asana), breathing methods (pranayama), and meditation (dhyana). To test the hypothesis that specific yoga practices are associated with reduced psychological distress, 186 adults completed questionnaires assessing life stressors, symptom severity, and experience with each of these aspects of yoga. Each yoga sub-component was found to be negatively correlated with psychological distress indices. However, differing patterns of relationship to psychological distress symptoms were found for each yoga sub-component. Experience with asana was negatively correlated with global psychological distress (r = ?.21, p < .01), and symptoms of anxiety (r = ?.18, p = .01) and depression (r = ?.17, p = .02). These relationships remained statistically significant after accounting for variance attributable to Social Readjustment Rating Scale scores (GSI: r = ?.19, p = .01; BSI Anxiety: r = ?.16, p = .04; BSI Depression: r = ?.14, p = .05). By contrast, the correlations between other yoga sub-components and symptom subscales became non-significant after accounting for exposure to life stressors. Moreover, stressful life events moderated the predictive relationship between amount of asana experience and depressive symptoms. Asana was not related to depressive symptoms at low levels of life stressors, but became associated at mean (t[182] = ?2.73, p < .01) and high levels (t[182] = ?3.56, p < .001). Findings suggest asana may possess depressive symptom reduction benefits, particularly as life stressors increase. Additional research is needed to differentiate whether asana has an effect on psychological distress, and to better understand potential psychophysiological mechanisms of action.     

The effect of superstitious thinking on psychosocial stress responses and perceived task performance

Previous research on superstitious belief, a subset of paranormal belief (Irwin, 1993 ), has suggested that people tend to invoke luck‐related superstitions in stressful situations as an attempt to gain an illusion of control over outcomes. Based on this, the current study examined whether luck‐related superstition, in the form of a “lucky” pen, could influence the psychological response to a psychosocial stressor. Participants (N = 114), aged between 17 and 59 years (M = 22.98, SD = 4.57) from James Cook University Singapore, were randomly assigned to one of four conditions: (a) no‐stress with no lucky pen; (b) no‐stress with a lucky pen; (c) stress with no lucky pen or; (d) stress with a lucky pen. The results revealed that participants provided with a lucky pen experienced lower state anxiety when exposed to the stressor. Further, participants provided with a lucky pen perceived their performance to be better than those without it. However, superstitious belief did not significantly change following exposure to stress. Taken together, the present findings add some support to the suggestion that belief in transferable luck may facilitate coping with a stressor. However, further research is needed to fully understand the mechanisms behind the potential benefits of superstitious belief.     

儿童版特里尔社会应激测试对儿童唾液皮质醇、唾液α-淀粉酶和情绪的影响

研究以150名五、六年级的学生为被试,考察儿童版特里尔社会应激测试（TSST-C）对儿童客观生理反应（唾液皮质醇和唾液α-淀粉酶）和主观情绪反应的影响。结果发现,TSST-C引起了儿童显著的应激反应,包括皮质醇和唾液α-淀粉酶水平的升高,以及主观消极情绪（如焦虑和紧张）的增加,这表明TSST-C在中国儿童中的适用情况良好,能够有效诱发儿童的应激反应。同时,研究也发现,皮质醇反应和唾液α-淀粉酶反应不存在相关,生理反应和情绪反应之间也不存在相关。     

Intersectional experiences of discrimination in a low‐resource urban community: An exploratory latent class analysis

There have been increasing calls for the application of an intersectionality framework to understand and address discrimination and health inequities among diverse communities. Yet there have been theoretical debates regarding to whom intersectionality applies and how intersectional experiences of discrimination are associated with health outcomes. The current study aimed to contribute to these theoretical debates and inform practical applications to reduce health inequities. Data were drawn from a community health survey in New Haven, CT (N = 1,293 adults) and analysed using latent class analysis. Results yielded 4 classes. Members of the 4 classes were similar sociodemographically. Three classes of participants reported experiencing discrimination, and members of these classes had greater stress, higher rates of smoking and sleep disruption, and worse overall health than members of the class reporting no discrimination. Members of 2 classes made multiple, or intersectional, attributions for discrimination, and members of these classes reported the most frequent discrimination. Findings suggest that community members who are sociodemographically similar may have diverse discrimination experiences. Multilevel interventions that address multiple forms of discrimination (e.g., racism and sexism) may hold promise for reducing discrimination and, ultimately, health inequities within low‐resource urban community settings.     

Worry and rumination: do they prolong physiological and affective recovery from stress?

Background: Anxiety and depression have been linked to repetitive negative self-regulation styles in the form of worry and rumination respectively. Following predictions of the metacognitive model [Wells, A., & Matthews, G. (1994). Attention and emotion: A clinical perspective. Hove: Erlbaum], the current study compared the effect on recovery from stress of three strategies: worry, rumination, and distraction using a stress exposure paradigm. It was predicted that worry and/or rumination would be associated with delayed recovery on physiological and/or self-report indices when compared to distraction.

Method: Fifty-four participants were randomly assigned to one of the self-regulation conditions and then completed a modified version of the Trier Social Stress Test [TSST; Kirschbaum, C., Pirke, K. M., & Hellhammer, D. H. (1993). The “TSST” – A tool for investigating psychobiological stress responses in a laboratory setting. Neuropsychobiology, 28, 76–81. doi:10.1159/000119004]. Skin conductance and negative affect (NA) measurements were obtained at six different time points.

Results: Skin conductance indicated a prolonged recovery in the rumination condition when compared with the distraction condition. Individuals in the worry condition reported an immediate-delayed recovery from stress marked by higher NA scores in comparison to the distraction condition.

Conclusions: These findings may provide important insights into the effects of different forms of repetitive negative thinking on physiological and psychological recovery from stress. The different response patterns observed are discussed within the context of the metacognitive model.
