This study examines affective and behavioral symptomatology in two groups of school-age children who were traumatized to different degrees during the war in Croatia (N = 1034). Six self-reported questionnaires were used to assess the following: number and type of war experiences, PTSD symptoms, anxiety, depression, psychosomatic symptoms, and psychosocial adaptation. Canonical discriminant analysis yielded a significant discriminant function that indicates moderate differentiation between the two groups of children according to the assessed symptoms. The results of a 2 x 2 x 2 ANOVAs (gender x age x level of traumatization) indicate that the children's reactions to war traumata varied in respect to all factors, as well as their interaction. The results indicate that gender differences are more prominent in older children. Older girls report more posttraumatic stress reactions, anxiety and depression, but at the same time seem better adapted than boys. Younger children, particularly those who survived more war even report more PTSD symptoms than older children. 相似文献

We examined the effect of rotation-induced stress on the percentage distribution of NK-YAC-1 target-binding cells and natural killer (NK) cell activity from splenic lymphocytes of C3H/HeJ mice. Following a 6-day stress regimen, we observed a marked decline in both the percentage of target-binding cells and in NK cell activity. This decline was first evident 13 days after initiation of stress and persisted for 2 weeks. Our data indicate that intermittent rotation stress over a 6-day period results in a delayed but persistent deleterious effect on NK-YAC-1 target binding and NK cell activity. 相似文献

Post‐traumatic stress disorder and anxiety symptoms in children exposed to the 1999 Greek earthquake
《British journal of psychology (London, England : 1953)》2004,95(3):387-397
Five months after the Athens earthquake of September 1999, 178 children from three districts of Athens at increasing distances from the epicenter were administered questionnaires to identify symptoms of post‐traumatic stress disorder (PTSD), anxiety and the extent of personal threat experienced. It was found that PTSD and anxiety symptoms were significantly related to proximity to the epicenter, exposure to threat and female gender. Age did not have a significant main effect on either anxiety or PTSD symptoms, but there were significant interactions between age and the other main variables. In the region closest to the epicenter, the youngest children reported the highest PTSD and anxiety symptom scores, but in the group furthest from the epicenter the older children reported the highest PTSD and anxiety symptom scores. These findings were discussed in relation to direct and media‐imparted exposure to the earthquake. 相似文献

Children prenatally exposed to cocaine may be at elevated risk for adjustment problems in early development because of greater reactivity and reduced regulation during challenging tasks. Few studies have examined whether cocaine-exposed children show such difficulties during the preschool years, a period marked by increased social and cognitive demands and by rapid changes in reactivity and regulation. The authors addressed this question by examining frustration reactivity and regulation of behavior during a problem-solving task in cocaine-exposed and -unexposed preschoolers. Participants were 174 4.5-year-olds (M age = 4.55 years, SD = 0.09). Frustration reactivity was measured as latency to show frustration and number of disruptive behaviors, whereas regulation was measured as latency to approach and attempt the problem-solving task and number of problem-solving behaviors. Results indicated that cocaine-exposed children took longer to attempt the problem-solving task but that cocaine-exposed boys showed the most difficulties: They were quicker to express frustration and were more disruptive. Effect sizes were relatively small, suggesting both resilience and vulnerabilities. 相似文献

Pathological stress responses are implicated in numerous disorders. Hypothalamic-pituitary-adrenal axis function is influenced by gene-environment interaction, with early-life environmental adversity having long-lasting effects. We examine the evidence that, in humans, these effects are apparent from infancy. We systematically reviewed published findings on cortisol response to a stressor, in 0-5-year-olds already exposed to adversity. Adversity was defined as a negative environmental influence present post-conception. We searched Ovid MEDLINE (1950-May 2010), EMBASE (1980-May 2010) and PsychINFO (1806-May 2010). We included peer-reviewed, English language studies that analysed salivary cortisol before and after a standardised stressor. We identified 30 studies, of which 27 reported a significant effect of adversity on the cortisol response to stress. Six of these demonstrated an effect of prenatal substance exposure. Thirteen studies found that psychosocial adversity increased cortisol reactivity. Three studies reported that cortisol reactivity could be normalised by intervention programmes. The studies were heterogeneous, both in nature of adversity studied and in stressor used, precluding meta-analysis and assessment of publication bias. Our review presents evidence that adversity disrupts the stress response from an early age. Longitudinal studies are required to determine whether effects persist, alter with time, or are reversible with intervention. 相似文献

A task force on war-related stress was convened to develop strategies for prevention and treatment of psychological, psychosocial, and psychosomatic disorders associated with the Persian Gulf War and other extreme stressors facing communities in general. The task force focused on the return home, reunion, and reintegration of service personnel with their families and work. Although the Persian Gulf War was won with relative ease, negative psychological sequelae may develop in some individuals because of the stress of war, family disruption, financial difficulty, and changes in family routines. Typical stress reactions and modes of coping that are usually unsuccessful or destructive were outlined, and suggestions were made for monitoring these. In addition, guidelines for successful coping were developed. Special attention was given to children's reactions and needs. Recommendations were made for outreach and intervention on the policy, systems (e.g., schools, businesses, governmental agencies), family, and individual levels. 相似文献

Using M3/38 monoclonal antibody we have analyzed effects of immobilization stress on the expression of galectin-3 in liver, spleen and peritoneal macrophages from adult RFM and C3H mice, as well as from aged C3H mice (total of 22 animals). In all analyzed tissues, immobilization stress caused a significant decrease in the expression of galectin-3, ranging from 14% to 47%. The decrease of galectin-3 was observed in both strains of mice, as well as in old animals. Moreover, the same range of decrease (approximately 50%) was observed when cells grown in vitro were exposed to subculturing, or heat-shock. Although the biological significance of this effect is not known, it is very interesting that a single episode of immobilization stress was sufficient to cause a significant decrease in galectin-3, implicating that this beta-galactoside-binding lectin might be involved in the physiological response to psychological stress. 相似文献

Factor analytic studies of trauma victims' posttraumatic stress disorder (PTSD) have offered conflicting hypotheses about how to conceptualize PTSD into symptom categories. The present study used confirmatory factor analyses of self-reported PTSD symptomatology from 5,664 child and adolescent victims of Hurricane Hugo to compare 10 models of PTSD dimensionality. PTSD was best represented by a 2nd-order PTSD factor that manifests in 3 symptom clusters (Intrusion/Active Avoidance, Numbing/Passive Avoidance, and Arousal). This model was cross-validated on 3 age groups (late childhood, early adolescence, and late adolescence), and results indicated factorial invariance across groups. PTSD symptoms varied in relative centrality to the underlying dimensions of PTSD, which differed in their relations with anxiety and degree of traumatic exposure. Implications for classification criteria and an empirically supported theory of PTSD are discussed. 相似文献

Children 4 to 6 years of age made choices among colors that had been associated with numbers. Prior to learning four number-color associations, pretraining on counting and ordering objects was given to half of the Ss. Associations were established by either absolute (paired associate) or relative (choice discrimination) methods, and then tests involving "more or less" questions on each of the possible six color pairs were given. Numerical associations were acquired best with absolute training or counting-ordering pretraining. Using the children's justifications for their responses, the test data were fit by Estes's (1966) scanning model; a response strength model based on Luce's (1959) axiom failed. Young children apparently possess an ordered numerical scale, can map this scale onto other nonquantitative symbols, and can generate, compare, and make ordinal decisions using these symbols. 相似文献

War can be defined as organized political violence among two or more nations. In accordance with the purpose, processes and
results of war, the ethics of war generally comprises three aspects: right ethics, action ethics and duty ethics. The most
important issue in ethics of war is “justice”. “Justice” and “injustice” as a conceptual pair do not prescribe the objective
character of war but rather convey a subjective attitude and ethical position that have the potential to compel a populace
to either support or oppose a war.

The enhancement of positive mental health in children is discussed as a needed emphasis in the area of pastoral care to children and youth. Three modes of providing such enhancement are given. These are parenting education services, mental health exercises for the children or youth, and preaching and worship ministries in the local church. Illustrations and applications of each are discussed. 相似文献

The aversive impact of combat and combat-induced posttraumatic stress disorder (PTSD) on parenting of young children has been examined in a few studies. Nevertheless, the toll of war captivity on parenting and the long-term relations between posttraumatic symptoms and paternal parenting of adult children remains unknown. This longitudinal study examined paternal parenting of adult children among war veterans, some of whom were held in captivity. Furthermore, we examined the mediating role of PTSD symptoms in the association between captivity and parenting. The sample included two groups of male Israeli veterans from the 1973 Yom Kippur War: ex-prisoners of war (ex-POWs) and comparable veterans who had not been held captive. Both groups were assessed via self-report measures of PTSD at three time points: Time 1 (18 after the war), Time 2 (30 after the war), and Time 3 (35 after the war) years after the war. Results shows that ex-POWs reported lower levels of positive parenting compared to comparison group veterans at Time 3. Furthermore, PTSD symptoms at Time 1, Time 2, and Time 3 mediated the association between captivity experience and parenting at Time 3. In addition, it was found that increases in the levels of PTSD symptom clusters over time were associated with lower levels of positive parenting at Time 3. 相似文献

A number of studies have considered whether background stress affects cardiovascular responses to acute stress tasks. The present study considers the effect of a potent background stressor with a clear onset, namely the terrorist attacks on September 11, 2001. Specifically, the authors investigated differences among 9.5-year-old children tested before (N = 30) and then following (N = 20) the 9/11 attacks. In addition, a majority of these children (N = 37) were retested approximately 1 year later (i.e., before and after 9/11/2002). Children tested directly following 9/11/2001 exhibited significantly greater stroke volume and cardiac output responses to acute stress tasks compared with their responses 1 year later, and this change in reactivity differed significantly from the change in reactivity exhibited by children tested before 9/11/2001 and again 1 year later. These results suggest that a potent background stressor can temporarily heighten some children's cardiovascular responses to subsequent acute stressors. 相似文献

Throughout history, military children and families have shown great capacity for adaptation and resilience. However, in recent years, unprecedented lengthy and multiple combat deployments of service members have posed multiple challenges for U.S. military children and families. Despite needs to better understand the impact of deployment on military children and families and to provide proper support for them, rigorous research is lacking. Programs exist that are intended to help, but their effectiveness is largely unknown. They need to be better coordinated and delivered at the level of individuals, families, and communities. Research and programs need to take a comprehensive approach that is strengths based and problem focused. Programs for military children and families often focus on the prevention or reduction of problems. It is just as important to recognize their assets and to promote them. This article reviews existing research on military children and families, with attention to their strengths as well as their challenges. Issues in need of further research are identified, especially research into programs that assist military children and families. Military children and families deserve greater attention from psychology. 相似文献

Diurnal influences on natural killer (NK) cell changes to acute stress were assessed in 21 men and 21 women assigned to either an acute stress (mental arithmetic) or control task condition. Sessions began at either 8 a.m. or 2 p.m. Number of NK (CD3-CD56+) cells and NK activity were measured at baseline, during the 5-min task, and 60 and 90 min after the task. Both morning and afternoon stress participants had elevated NK cell numbers during the task. After the task, number of NK cells decreased in morning stress participants but remained significantly above baseline levels 60 and 90 min posttask. NK cell numbers in afternoon stress participants decreased to below baseline levels 60 and 90 min after the task. Changes in NK activity were driven primarily by diurnal influences. NK activity increased in all morning participants and stayed increased 60 and 90 min posttask. NK activity of all afternoon participants also increased during the task but dropped below baseline 60 and 90 min later. Greater increases in NK levels and activity during the task were associated with greater heart rate changes. 相似文献

OBJECTIVE: Among the neurocognitive impairments reported as associated with prenatal cocaine exposure, slower response time, and less efficient learning in school-aged children are common to findings from several laboratories. This study presents performance data on a spatial working memory task in 75 prenatally cocaine exposed (CE) and 55 nondrug-exposed (NDE) 8- to 10-year-old children. METHODS: Children were administered a novel neuropsychological measure of immediate- and short-term memory for visuospatial information, the Groton Maze Learning Test (GMLT), a computer-based hidden maze learning test that consists of a "timed chase test" (a simple measure of visuomotor speed), eight learning trials followed by a delayed recall trial after an 8-minute delay and a reverse learning trial. Performance is expressed as correct moves per second and number of errors per trial. RESULTS: Across all trials, the cocaine-exposed group showed significantly slower correct moves per second and made significantly more errors. There were no significant main effects for amounts of alcohol, tobacco, or marijuana exposure. After an 8-minute delay and compared to the eighth trial, cocaine-exposed children showed less consolidation in learning compared to nonexposed children. When asked to complete the maze in reverse, cocaine-exposed children showed a greater decrement in performance (decreased correct moves per second and increased errors) compared to the eighth learning trial. CONCLUSIONS: Children exposed in utero to cocaine exhibit a possible impairment in procedural learning and diminished efficiency in creating and accessing an internal spatial map to master the hidden maze. 相似文献

The contribution of loneliness and posttraumatic stress disorder to marital adjustment following war captivity: a longitudinal study 总被引:1,自引:0,他引:1
This prospective study examined the relative contribution of loneliness and posttraumatic stress disorder (PTSD) to marital adjustment among Israeli veterans of the 1973 Yom Kippur war. Specifically, we examined the mediating role of loneliness as measured in 1991 in the association between PTSD as measured in 1991 and marital adjustment as measured in 2003. Our sample consisted of 225 participants divided into 2 groups: ex-prisoners of war (ex-POWs) (N = 122) and a comparison group comprised of veterans who fought in the same war but who had not experienced captivity (N = 103). The findings demonstrate that ex-POWs display lower levels of marital adjustment and higher levels of PTSD than controls. Loneliness was found to mediate the relationship between PTSD as measured in 1991 and marital adjustment as measured in 2003 for both ex-POWs and controls. Further, for ex-POWs, loneliness contributes to marital adjustment above and beyond the contribution of PTSD as measured in 2003. The theoretical implications of loneliness for the marital relationships of traumatized ex-POWs are discussed. 相似文献
