Evidence for memory characteristic differences between trauma and other memories in non‐clinical samples is inconsistent. However, trauma is frequently confounded with the event recalled. This study compares trauma and nontrauma memories for the same event, childbirth, in a non‐clinical sample of 285 women 4–6 weeks after birth. None of the women met diagnostic criteria for post‐traumatic stress disorder. Traumatic birth, defined by the DSM‐5 event criterion, was reported by 100 women. The ratings of some memory characteristics did not differ between memories for traumatic and nontraumatic birth: All were rated highly coherent and central to women's lives, with moderate sensory memory. However, women who experienced traumatic births reported more involuntary recall, reliving, and negative/mixed emotions. Thus, trauma memories differed from nontrauma memories. In this non‐clinical sample, this is likely to be due to encoding during trauma rather than the distinctive memory profile for memories retrieved by those experiencing trauma symptoms.  相似文献

Sleep problems are prevalent among Veterans. Left untreated, such problems may elevate psychological distress and increase risk of subsequent mental health disorders. Psychological resilience may buffer against negative psychological outcomes, yet the relationship between sleep and resilience has not been studied. This study explored poor sleep, resilience, and psychological distress using questionnaires collected as part of the Study of Post-Deployment Mental Health. Participants (N = 1,118) had served in the US military since September 11, 2001, had one or more overseas deployments, and were free from a past-month DSM-defined mental health disorder. Hierarchical linear regression was used to examine the association between poor sleep quality (Pittsburgh Sleep Quality Index total score) and psychological distress (Global Symptom Index; Symptom Checklist-90-R), controlling for demographic and health characteristics. Moderation analyses tested for a potential buffering effect of resilience (Connor-Davidson Resilience Scale). Poor sleeping Veterans had worse physical and psychological health, lower resilience, and endorsed more lifetime traumatic events. Poor sleep was associated with greater psychological distress controlling for health and demographic characteristics. Both resilience factors—adaptability and self-efficacy—had significant buffering effects on the relationship between poor sleep and psychological distress, suggesting that resilience may protect against negative outcomes in poor sleepers. Additional research is warranted to better understand the relationships between sleep, resilience, and psychological distress. Such research may inform pertinent prevention efforts, including interventions that improve sleep, enhance resilience, and protect against incident mental health diagnoses.  相似文献

Although the health consequences of financial strain are well documented, less is understood about the health-protective role of social capital. Social capital refers to a sense of community embeddedness, which is in part reflected by group membership, civic participation, and perceptions of trust, cohesion, and engagement. We investigated whether perceptions of social capital moderate the relation between financial strain and health, both mental and physical. This longitudinal study surveyed adults in two communities in rural Ontario where significant job losses recently occurred. Data were collected on financial strain, social capital, perceived stress, symptoms of anxiety and depression, and physical health on three occasions over 18 months (N's = 355, 317, and 300). As expected, financial strain positively related to perceived stress, poor physical health and symptoms of anxiety and depression, whereas social capital related to less stress, better physical health, and fewer symptoms of anxiety and depression. Effects of financial strain on perceived stress and depressive symptoms were moderated by social capital such that financial strain related more closely to perceived stress and depressive symptoms when social capital was lower. The findings underscore the health-protective role of community associations among adults during difficult economic times.  相似文献

Religious congregations are uniquely poised to provide programs to support survivors of violence against women; yet little is known regarding the prevalence of such programs. In this study, we used data from three waves of the National Congregation Study (N = 3334) to examine change across time in the presence of a congregational program to support survivors of sexual assault or domestic violence. We also explored results among different Christian religious traditions across time. Given the gendered nature of this violence, we also tested whether the (a) gender of the head clergy (i.e., religious leader), and (b) ability of women to serve in congregational leadership roles predicted the presence of programs. As points of comparison, we also examined the total number of congregational social service programs and food programs in particular. Overall, we found different patterns of change across religious traditions for the different programs. Moreover, clergy gender and the ability of women to serve in leadership roles predicted the presence of different types of programs. Limitations, implications, and directions for future research also are discussed.  相似文献

This study presents a protocol for induction of moderate psychosocial stress and investigates its impact on psychological and physiological responses. The proposed procedure was designed to enable researchers to assess cognitive performance under effect of various classes of stressors. The protocol's structure contains three main periods: baseline, assessment, and recovery. The assessment stage starts with task anticipation, during which audience (three-member commission) is introduced and apparatus (cameras, microphones, lights, and physiological measuring devices) stationed. Subsequently, cognitive performance was tested. The protocol was evaluated on 56 university students that were randomly assigned to control or stress (protocol) treatment and administered three cognitive tests (working memory operation span, remote associates test, and semantic fluency). Compared to control sessions, protocol induced state anxiety, interfering worry thoughts, and disturbance during recovery period. In addition, the stress group also showed elevated levels of skin conductance, higher average heart rates, and larger drops in peripheral temperature. Even though more research is needed, these results suggest that the protocol effectively induces both psychological and physiological stress responses and therefore encourages utilization in cognitive-affective and cognitive-biological fields of research.  相似文献

Bibliometric analyses are applied to 35,975 citations from 721 articles published in the Journal of Personal Selling & Sales Management, spanning the journal’s first 35 years of existence (1980–2015). For each of three time periods (1980s, 1990s, and 2000s), the sales literature’s most influential article publications are objectively identified. Multidimensional scaling is then used to identify key intellectual themes across time. Based on the citation data, historical developments in the literature regarding (1) relationship marketing, (2) sales force technology, (3) sales force control systems, and (4) salesperson role stress are traced and briefly explored in some article-level depth. Co-citation trends and recently influential papers are used to identify opportunities for future research. Altogether, this paper presents a first-of-its-kind view of sales literature’s intellectual cornerstones, knowledge structure, and thematic developments over 35 years.  相似文献

African American women are often times characterized by stereotypes that can be traced back to slavery. Those stereotypes have been found to affect many outcomes in an array of domains related to work, intimate relationships, and personal well-being. The literature does not address how these stereotypes may affect adolescent African American girls. This study aimed to fill that gap by examining how the endorsement of stereotypes affects the psychological well-being, specifically stress, in 144 African American adolescent girls (N = 144) who ranged from 12–19 years old. This study goes a step further to investigate whether collective self-esteem can serve as a buffer between endorsement of stereotypes and perceived stress. Using combined mediation–moderation model, the analysis showed that there is a significant positive relationship between stereotypic beliefs and perceived stress that is buffered by moderate to high levels of collective self-esteem. Implications for treatment and policy, as well as educational recommendations are discussed.  相似文献
