Background and Objectives: Research increasingly demonstrates that trauma exposure can have cumulative effects, yet much remains to be learned about effects of cumulative trauma, particularly regarding longer term adjustment. One such trauma, combat exposure, is insufficiently understood, especially for women, who are increasingly engaged in professional combat activities. Design: The study comprised a cross-sectional survey assessing multiple aspects of current well-being in women approximately 25 years after their service in Vietnam during the Vietnam War. Methods: Participants were 1374 women (78% military and 22% nonmilitary; mean age = 59.7). This study investigated the relations between three separate categories of trauma exposure (childhood, adulthood, and combat) and well-being and examined whether perceived social support at return from Vietnam moderated the association between combat exposure and well-being. Results: While both childhood and adulthood trauma exposure related to midlife well-being, combat exposure still uniquely predicted outcomes. Further, postdeployment perceived social support moderated the association of combat and well-being: recollected higher perceived social support at homecoming buffered participants from the links between combat exposure and well-being. Conclusions: These results may have important implications for interventions to reduce the impact of traumatic experiences, particularly in light of the increasing exposure of women to direct combat events. 相似文献

Abstract The aim of this study was to test whether coping responses mediated the influence of perceived social support on symptoms of anxiety/depression, social withdrawal, and aggressive behavior in American (N=349) and Spanish students (N=437). Participants completed measures of perceived support, social stress, coping, and distress. Coping partially mediated relations between perceived support and distress, with coping mediation most evident in individuals facing high levels of social stress. Decreased use of disengagement coping by individuals with high perceived support appears to partially explain the protective value of perceived social support. Multiple group covariance structure analysis showed that models linking perceived support, coping, and distress were very similar across cultures, suggesting that the mechanisms underlying decreased risk for individuals with high perceived support may be relatively independent of cultural context, and that interventions designed to increase perceived support and decrease disengagement could be appropriate in both cultures. 相似文献

We compared long-term growth patterns in teachers’ and mothers’ ratings of Overt Aggression, Covert Aggression, Oppositional Defiance, Impulsivity/inattention, and Emotion Dysregulation across developmental periods spanning kindergarten through grade 8 (ages 5 to 13 years). We also determined whether salient background characteristics and measures of child temperament and parenting risk differentially predicted growth in discrete categories of child externalizing symptoms across development. Participants were 549 kindergarten-age children (51% male; 83% European American; 17% African American) whose problem behaviors were rated by teachers and parents each successive year of development through 8th grade. Latent growth curve analyses were performed for each component scale, contrasting with an overall index of externalizing, in a piecewise fashion encompassing two periods of development: K-1and grades 1–8. Our findings showed that there were meaningful differences and similarities between informants in their levels of concern about specific forms of externalizing problems, patterns of change in problem behavior reports across development, and in the extent to which their ratings of specific problems were associated with distal and proximal covariates. Thus, these data provided novel information about issues that have received scant empirical attention and have important implications for understanding the development and prevention of children’s long-term externalizing problems. 相似文献

Although most research with youth exposed to violent manmade disasters has focused on internalizing problems, recent work suggests conduct problems (CPs) may also manifest in exposed youth. However, the extent to which youth postevent CPs present independently, versus co-present in conjunction with PTSD symptoms, remains unclear. The present study examined PTS and CP symptom profiles among affected Boston-area youth following the 2013 Boston Marathon bombing. This study used latent profile analysis to identify distinct PTS and CP symptom profiles among Boston-area youth ages 4–19 years (N?=?344) affected by the Boston Marathon bombing events. PTS and CPs were measured using the UCLA-PTSD-RI and the SDQ parent reports, respectively. Analyses identified 3 distinct profiles: presentations characterized by (a) low PTS, low CPs, (b) moderate PTS, low CPs, and (c) high PTS, elevated CPs. The profile characterized by the highest PTS was the only profile with elevated CPs; hyperarousal and emotional numbing/avoidance symptoms showed the greatest distinguishing properties among profiles with and without elevated CP. Types of traumatic exposure experienced by youth were differentially associated with profiles. Specifically, direct (but not relational) exposure distinguished youth classified in the profile showing elevated CPs. Findings suggest interventions following violent manmade disasters may do well to incorporate CP modules when working with youth showing the greatest hyperarousal and emotional numbing, and/or who have directly witnessed the most violence. 相似文献

The promise of online cognitive behavioral therapy for insomnia (CBT-I) and other sleep-related problems as an alternative to traditional face-to-face treatment rests upon the accessibility, ease-of-use, and effectiveness of these approaches. Here we provide a review of Sleepio, a digitalized, state-of-the-art CBT-I program for adults, informed by our personal experience with the program, available research, and information provided at the Sleepio website. The 6-week treatment program can be completed flexibly via web-based or mobile platform. Initial assessment of individual goals and baseline sleep patterns is used to build a personalized account comprised of four sections: Sleep Diary, Case File, Library, and Community. Sleepio uses evidence-based principles and practices, engaging content, and an easy-to-follow format. Unique features of the program including synchronization with compatible sleep tracking devices, multiple built-in user supports, and a 14-day money-back guarantee. Both statistical and clinically meaningful sleep improvements have been found in a large randomized controlled trial. Overall, Sleepio represents a model program for online CBT-I delivery. 相似文献

Recent research using quantitative methodologies and an emerging social psychological theory of socioeconomic status (SES) has found an association between students’ SES and their academic achievement goals. As a new area of research in the achievement goal tradition, there has been little investigation of the contextual influences upon particular goal orientations in divergent SES contexts. To explore these influences, focus groups were conducted with 24 secondary school students aged 16–17 years attending a high and a low SES school in New South Wales, Australia. These teenagers were approaching a ‘developmental deadline’ which required immediate decisions about future work and education pathways. As such, they could be experiencing a period of heightened contextual influences. Directed content analysis of the focus groups observed the broad distinctions in achievement goals seen in previous quantitative studies. However, the analysis elucidated some of the ways in which norms and values in different SES contexts influenced the adoption of particular goal orientations. In some cases, the same orientation had markedly different contextual influences stemming from students’ SES backgrounds. From these exploratory findings, we argue for further research into the factors which influence the adoption of different achievement goals by students from different SES backgrounds. 相似文献

Although self-harming behavior is a common and costly problem for psychiatric inpatients released from the hospital, standardized tools that assess patients' risk for self-harm are rarely used in clinical settings. In this study of dually diagnosed psychiatric inpatients (N = 147), we assessed the utility of patients' self-perceptions of risk in predicting self-harm in the community. Patients' self-perceptions of risk predicted self-harm 8 weeks after discharge from the hospital (Lag 1; area under the curve [AUC] = 0.75). Self-perceptions of risk at the 8-week interview also predicted self-harm 2 months later (Lag 2; AUC = 0.72). Self-perceived risk added predictive utility above and beyond scores on a measure of depression and seemed to capture changes in risk state over time. The results suggest that inpatients can accurately perceive their own risk and therefore may be important collaborators in the risk management process. 相似文献

Cognitive-behavioral therapy (CBT) for anxiety disorders in youth has been evaluated in randomized clinical trials and found
to be an efficacious treatment. Studies have investigated the effects of increased parental/family involvement in treatment.
In the majority of these studies, however, parental involvement is synonymous with maternal involvement leaving the role of
fathers unknown. Studies including parents in treatment have yet to examine the independent contribution of mothers and fathers
to child outcome. We examined the relationship between both mother (n = 45) and father (n = 45) attendance and engagement
in therapy sessions, maternal and paternal psychopathology, and child (n = 45) treatment outcome when parents were included
in a Family CBT program for anxiety-disordered youth. Some indications were found for the notion that greater rates of mother
and father attendance in session, as well as higher ratings of mother and father engagement in session, are associated with
improved child outcome. Parental psychopathology was not associated with attendance, engagement, or child outcome. Recommendations
for future research are offered. 相似文献
