Research on emotion and health has tended to focus on the negative consequences of “negative” emotions. An emerging literature has begun to explore the positive aspects of negative affect, suggesting that emotion be treated in a more differentiated way by recognising the components and intensity that can promote or harm health. For example, short bursts of emotion-associated sympathetic activation can stimulate parts of the immune system, whereas more chronic activation can cause “wear and tear” on the cardiovascular system. Anxiety and guilt have been associated with preventive health behaviours and care-seeking, whereas distress and depression increase symptom sensitivity, accuracy of illness perception, and can facilitate care-seeking and receipt of support. However, intense and chronic negative affects may lead individuals to engage in risky health behaviours, such as substance abuse, overeating, and high risk sex, as a coping mechanism to regulate negative emotion. They may also undermine social support systems, leading to a self-perpetuating cycle of conflict and isolation. Future research must address the parameters defining “healthy” and “unhealthy” negative emotion. 相似文献

The rates and associated features of suicidal ideation among 5,641 patients seeking routine, nonsuicide related care in an inner‐city emergency department were examined. Approximately 8% of patients seeking routine care in the emergency department reported some form of suicidal ideation within the past 2 weeks. Suicidal ideation was common in individuals who were single with poorer mental health, had higher depression, and had received some drug or alcohol treatment in the past 3 months or had used cocaine or marijuana in the past 30 days. Improved screening procedures could help to identify routine care patients who are at risk for suicide. 相似文献

OBJECTIVE: To examine smoking behaviors in Canadian youth from late childhood to adolescence. By following participants from as young as 10 and 11 years, the authors proposed to identify distinct developmental pathways of smoking acquisition. DESIGN: Growth mixture modeling was used to identify developmental trajectories of smoking among 10- to 17-year-old participants of the Canadian National Longitudinal Survey of Children and Youth. MAIN OUTCOME MEASURES: Developmental trajectories of trying smoking, smoking frequency, and smoking intensity. Results: Five developmental trajectories related to smoking frequency were identified, of which 2 were acquisition patterns that led to daily smoking at age 16-17, and 3 were experimentation patterns that led to nonsmoking at age 16-17. The largest variability in changes in smoking behavior over time was the reported level of smoking frequency. CONCLUSION: Analysis showed that there is more than 1 way in which Canadian children and adolescents acquire smoking behaviors over time. The authors were able to differentiate patterns of experimentation from patterns of acquisition. Whereas experimentation has been generally considered as 1 of the stages in the smoking acquisition process leading to regular smoking, these results indicate that experimentation can be described as a distinct process in itself. 相似文献

Background. Although teacher–student relationships lie at the heart of students’ schooling experience, fundamental questions regarding these relationships remain unanswered. Aims. This study investigates three related questions about these relationships: To what extent do they change from the beginning to the end of a school year? Are any emergent changes associated with shifts in students’ academic or motivational outcomes? Are certain ‘upstream’ factors associated with improvements or declines in teacher–student relationships? Sample. We investigate these questions with a sample of middle school students (N = 119) and their teachers (N = 30). Methods. Through a novel approach which accounts for both perspectives within teacher–student relationships, we assess these relationships at the beginning and end of the school year. Using multi-level models, we examine how changes in these relationships are associated with changes in students’ grades, homework completion rates, self-efficacy, and effort. In addition, we examine associations with two potential precursors to teacher–student relationships: students’ accuracy in taking their teachers’ perspective and their perceptions of similarity to their teachers. Results. We find that substantial changes occur in these relationships from the beginning to the end of the year; these changes are associated with shifts in important student outcomes; and changes in students’ social perspective taking accuracy and perceived similarity to their teachers correspond with changes in teacher–student relationships. Conclusions. Given the malleability of teacher–student relationships and their importance for key achievement and motivational outcomes, we advocate for researchers to conduct field experiments to inform how to improve these critical relationships. 相似文献
