The current study aimed to assess the prevalence of PTSD among Palestinians who sustained serious bodily injuries during theintifada, as well as to delineate factors having an effect on the development and attenuation of PTSD symptomatology. Results indicated evidence of high prevalence of PTSD among the injured. No significant differences in PTSD prevalence for demographic, situational, and trauma-related variables were found except for the age factor. Prevalence of PTSD among adolescents was significantly higher than among adults. It seemed that the injury itself was so intensely overwhelming that the other variables were overshadowed. Implications for further research and stress management techniques were discussed. 相似文献

The parents of 14 individuals with severe/profound mental disabilities were interviewed one and three years after their children graduated or aged out of high school. Two categories of information were sought concerning the adult adjustment of these individuals. General status variables included marital status, place of residence, agencies contacted concerning employment opportunities, financial resources, leisure activities, means of transportation, sources of help in resolving problems, and amount of postsecondary training. Employment variables included location of employment, wages, number of hours worked per week, and job benefits received. Results indicated that three years after exiting high school, all participants were very dependent upon others for housing, transportation, and financial assistance. Ten of the 14 individuals were employed 3 years after exiting high school, all in sheltered workshops. 相似文献

Cluster analysis of the MMPI has been utilized widely in the chronic low back pain literature to try to identify reliable patient subtypes predictive of treatment outcome. We extended this methodology to patients with heterogeneous chronic medical conditions by replicating prototypic MMPI cluster group profiles and by relating cluster groups to clinical baseline and outcome data. Subjects were two independent samples (n=254 and n=263) of chronically ill patients admitted to an inpatient medicine/psychiatry unit. Using a four-cluster solution, similar cluster profile groups were replicated in both samples. Consistent differences emerged between cluster groups on functional impairment, psychiatric diagnoses, depression, and psychosomatic symptoms. Cluster group membership also predicted changes in functional impairment and depression six months after treatment. Results are discussed in terms of similarities between chronic low back pain and chronic illness and tailoring treatment to different patient types.This research was supported in part by a grant from the Henry J. Kaiser Family Foundation. 相似文献

ABSTRACTFocusing on the father-child-relationship in a family systems perspective, this paper investigates longitudinal links of parenting, interparental conflict, and positive regard by both parents, to their emotional insecurity with father and mother. Furthermore, to clarify fathers’ contribution to children’s social development, aspects of the relationship to both parents are jointly considered. The sample was drawn from the German family panel pairfam and included 372 family triads with parents’ and children’s self-reports. Findings revealed consistent associations between interparental conflict and lack of positive regard and emotional insecurity, while parenting had no independent links with children’s emotional insecurity or social adjustment. Controlling for the stability of child outcomes, interparental conflict predicted children’s lower prosocial behavior and higher peer rejection. In addition, peer rejection was predicted by children’s emotional insecurity with father. The findings are in line with the emotional security hypothesis and highlight the importance of the father-child-relationship for developing positive peer relationships. 相似文献

Examined the adjustment of 6- to 18-year-old children and adolescents(n = 38) 2 to 5 years postdiagnosis of brain tumor with respectto standardized measures of anxiety and depression; self-perceptions;and adaptive living skills. Child, mother, and teacher reportdata were used. Maternal adjustment (anxiety and depression,parenting stress) was also assessed. Children and adolescentssurviving brain tumors reported themselves to be generally withinthe normal range. However, maternal ratings of social problemswere higher than normative scores and significantly lower thannorms on social problems, scholastic competence, and communicationskills. Teacher ratings on the Teacher Rating Form were allwithin normal limits. Maternal adjustment measures were withinthe normal range, although the Parent-Child Dysfunctional Interactionsubscale of the Parenting Stress Index was elevated. No differencesin scores were found between children in regular and specialeducation, or between children who had received radiation andthose who did not. This sample of survivors of pediatric braintumors and their mothers had relatively mild problems in adjustment,supporting a competency-based view of the adaptation of pediatricpatients and their families. 相似文献

Comprehensive Assessment of Pain in Juvenile Rheumatoid Arthritis: An Empirical Model 总被引:1,自引:0,他引:1
Thompson Karen L.; Varni James W.; Hanson Virgil 《Journal of pediatric psychology》1987,12(2):241-255
A comprehensive assessment model of variables hypothesized toinfluence pediatric pain perception was empirically investigatedin 23 families who had a child with juvenile rheumatoid arthritis.To determine the effects of family environment, child psychologicaladjustment, and disease parameters on child pain perception,a developmentally appropriate model was developed. Childrenbetween the ages of 5 and 15 were found to be reliable judgesof their pain intensity. Several family environmental and childpsychological factors were found to interact with specific diseaseparameters in determining pediatric pain perception and report.A multidimensional age-appropriate assessment model is suggestedfor use in the further examination of pediatric chronic andrecurrent pain. 相似文献

A Contextual Family/Systems Approach to Pediatric Psychology: Introduction to the Special Issue 总被引:2,自引:5,他引:2
Introduced the special issue on "Family System in PediatricPsychology" by organizing the papers around a series of themesrelevant to understanding families in pediatric psychology.Themes reflect the relationships between parent and child adjustment,family subsystems, legacies and traditions, social support systems,family interventions, the constancy of change in families, thechallenges of conducting longitudinal research, the inclusionof fathers, and the importance of a competency framework inpediatric family psychology. The paper concludes with recommendationsfor pediatric family psychology, including suggestions for increasingdiversity, expanding methodological approaches, and enhancingfamily competence. 相似文献

Hope, Coping, and Adjustment Among Children with Sickle Cell Disease: Tests of Mediator and Moderator Models 总被引:4,自引:2,他引:4
Tested mediator and moderator models of hope, coping, and adjustmentin 39 children with sickle cell disease. In home interviewsparents provided information on demographics and functionaladjustment. Children self-reported levels of hope, coping strategies,and psychological adjustment. Coping strategies moderated, butdid not mediate, the relationship between hope and adjustment.Hope was negatively associated with anxiety when active coping,support coping, and distraction coping was high. Avoidance copingdid not moderate the hope-adjustment relationship but was positivelyrelated to anxiety. No effects were found for depressive symptomsor for the functional measures of adjustment. 相似文献

Summary Benzbromarone is one of the main uricosuric drugs currently used. We determined plasma concentrations of benzbromarone, bromobenzarone, and benzarone and 24 hour uric acid excretion in ten healthy individuals following fasting application of two different non-micronised benzbromarone brands. In addition we explored the influence of adjusting urinary pH to near neutral values and of concomitant food intake. Benzbromarone was more rapidly absorbed from the test preparation than from the reference preparation; the extent of systemic availability did not differ significantly. Urinary pH adjustment had no clearcut effect, whereas food intake retarded drug absorption (even though not significant because of the variability of the data). Binding of benzbromarone to plasma proteins exceeded 99%. Bromobenzarone and benzarone were not detectable and are unlikely to be major metabolites of benzbromarone. Instead we found two other compounds suggestive of metabolites, one of them being monohydroxilated benzbromarone. The plasma concentrations of the parent compound in one subject exceeded those of the rest of the group, possibly indicating genetic differences in drug metabolism. The uricosuric effect was not related to benzbromarone plasma concentrations.Abbreviations AUC
