Occupational stress has a significant adverse effect on workers’ well-being, productivity, and performance and is becoming a major concern for both individual companies and the overall economy. To reduce negative consequences, early detection of stress is a key factor. In response several stress prediction methods have been proposed, whose primary aim is to analyse physiological and behavioural data. However, evidence suggests that solutions based on physiological and behavioural data alone might be challenging when implemented in real-world settings. These solutions are sensitive to data problems arising from losses in signal quality or alterations in body responses, which are common in everyday activities. The contagious nature of stress and its sensitivity to the surroundings can be used to improve these methods. In this study, we sought to investigate automatic stress prediction using both surrounding stress data, which we define as close colleagues’ stress levels and the stress level history of the individuals. We introduce a real-life, unconstrained study conducted with 30 workers monitored over 8 weeks. Furthermore, we propose a method to investigate the effect of stress levels of close colleagues on the prediction of an individual’s stress levels. Our method is also validated on an external, independent dataset. Our results show that surrounding stress can be used to improve stress prediction in the workplace, where we achieve 80% of F-score in predicting individuals’ stress levels from the surrounding stress data in a multiclass stress classification. 相似文献

Previous research has identified several individual-level factors that modify the risk of childhood trauma on adult psychiatric symptoms, including symptoms of major depression (MD) and posttraumatic stress (PTS). Neighborhood-level factors also influence the impact of individual-level exposures on adult psychopathology. However, no prior studies to our knowledge have explored cross-level interactions between childhood trauma and neighborhood-level factors on MD and PTS symptoms. The purpose of this study was therefore to explore cross-level interactions between a neighborhood-level factor – neighborhood-level crime – and childhood trauma on MD and PTS symptoms. Participants in this study (N = 3192) were recruited from a large public hospital, and completed self-report inventories of childhood trauma and MD and PTS symptoms. Participant addresses were mapped onto 2010 census tracts, and data on crime within each tract were collected. Multilevel models found a significant cross-level interaction between childhood trauma and neighborhood crime on MD symptoms, such that the influence of high levels of childhood trauma on MD symptoms was enhanced for participants living in high-crime neighborhoods. Supplementary analyses found variation in the strength of cross-level interaction terms by types of childhood trauma and crime, with the strongest associations including emotional neglect paired with personal and property crime. The results provide preliminary support for interventions that help childhood trauma survivors find housing in less vulnerable neighborhoods and build skills to cope with neighborhood crime. 相似文献

观察了大运动量训练期8名自由式摔跤运动员应激激素、焦虑水平及主观强度感的变化。研究过程中,每周安排11次大运动量训练,共进行2次实验,每次3个取样点(运动前、即刻和次日晨)。结果显示,两次取样时期次日晨ACTH水平较运动后即刻明显降低;C水平在第二次取样运动后即刻水平和次日晨水平明显高于运动前的,并且该时期运动后即刻C水平也明显高于第一次取样时期运动后即刻水平;E水平在第二次取样运动后即刻水平明显高于第一次取样运动后即刻的,且次日晨该激素水平也明显高于第一次取样次日晨的;血浆β-END水平在第二次取样运动后即刻水平明显高于运动前,也高于第一次取样运动后即刻,第二次取样次日晨该激素水平均低于运动前和运动后即刻水平,同时低于第一次取样次日晨的;血清NE水平变化与β-END水平变化类似;而RPE等级和焦虑水平在两次测试中呈现出运动后即刻水平高于运动前和次日晨的趋势,但不明显;RPE等级与诸多应激激素之间存在着弱相关关系。这预示着,在运动员身体机能评定工作中欲采用简单易行的显示身体机能的外部指标来表现不易测到的内部变化还需努力。 相似文献

In this article, Tina Axup, an educational psychologist working in Southend‐on‐Sea, and Irvine Gersch, director of educational and child psychology programmes at the University of East London, describe a small‐scale study of teachers' attitudes regarding the impact of student behaviour on their professional lives. Anecdotal evidence within a local authority educational psychology service suggested that increasing teacher concern about student disruptive behaviour was causing significant professional anxiety. Tina Axup formulated a brief questionnaire to explore teacher perceptions of the student responses that appeared to cause them stress. Although it is difficult to generalise from the results because of the small sample size and low return, the most frequently selected behaviours seen as challenging were found to be ‘low level’, ‘verbal’, ‘work avoidance’ and ‘out of seat behaviour’. The most frequent teacher reactions were said to be ‘frustration’, ‘bewilderment’, ‘shock’ and concern about the impact on other students in the class. The key favoured coping strategies reported included behaviour management techniques, praise and trying to understand the difficult behaviour, while personally talking to peers, switching off after the lesson, taking exercise and talking to family and friends. For future help, the preferred teacher options included the employment of more specialist behaviour support staff. Tina Axup and Irvine Gersch discuss the implications of these findings and identify further areas for research. 相似文献

The authors explored the relationship between counseling trainees' emotional intelligence (EI), empathy, stress, distress, and demographics. Results indicated that higher levels of EI were associated with lower stress and distress, higher affective and cognitive empathy, and age. These findings suggest curricular integration of EI and potential utility of EI measures to evaluate students' progress throughout the program. 相似文献

The present study highlights teacher stress related to student mental health promotion through the relationship between perceived competence, perceived responsibility and negative emotions. Data were derived from a mixed methods design, utilizing three focus group interviews (n = 15), followed by survey research (n = 771) amongst Norwegian K–12 teachers. The results suggest that teacher stress emerges chiefly from a mismatch between feeling responsible for and being able to help students with mental health problems. The data also point to the impact of time constraints in school context. Finally, the findings reveal significantly higher levels of perceived responsibility and negative emotions amongst female teachers, and significantly lower levels of perceived responsibility amongst teachers at higher grades. 相似文献
