Although there has been a substantial effort to establish the beneficial effects of social support on health and well-being, relatively little work has focused on how social support influences physical health. This article outlines possible mechanisms through which support systems may influence the etiology of physical disease. I begin by reviewing research on the relations between social support and morbidity and between social support and mortality. I distinguish between various conceptualizations of social support used in the existing literature and provide alternative explanations of how each of these conceptualizations of the social environment could influence the etiology of physical disease. In each case, I address the psychological mediators (e.g., health relevant cognitions, affect, and health behaviors) as well as biologic links (e.g., neuroendocrine links to immune and cardiovascular function). I conclude by proposing conceptual and methodological guidelines for future research in this area, highlighting the unique contributions psychologists can make to this inherently interdisciplinary endeavor.  相似文献

This research developed a model for forensic release decisions that incorporated actuarial and psychiatric predictors. The model was based on research that compared 127 insanity acquittees in the State of Maryland with a matched control group of 127 convicted felons and a comparison group of 135 mentally disordered prison transfers. The three cohorts were followed for an average of 10 years after release from hospital or prison. Findings on two outcome indicators are reported in this article: rearrests within 5 years after release and overall functioning in the community during 2½ years after release. Discriminant analysis was performed on the outcome variable of rearrest; it was found to accurately predict the outcome of 75% of the subjects with the following six variables: adjustment in hospital, clinical assessment of hospital staff, Global Assessment Scale score at release, functioning prior to instant offense, heroin addiction, and birth order. A second discriminant analysis identified seven variables that accurately predicted the overall functioning of 80.4% of the insanity acquittees.  相似文献

Sex roles and social support as moderators of life stress adjustment   总被引:1,自引:0,他引:1  
In this study we used a longitudinal design to test the stress-buffering effects of sex role orientation in combination with perceived social support on measures of trait anxiety and depression. College undergraduates served as subjects. The cross-sectional analyses provided strong support for the hypothesis that masculinity would function as a life stress buffer. The hypothesis that social support would serve as a stress buffer when coupled with high masculinity was supported by one of the cross-sectional analyses as well as the longitudinal analysis. This pattern was found primarily for perceptions of tangible social support. The longitudinal analysis also revealed a significant interaction involving negative life events and masculinity and femininity. This interaction effect provided unexpected support for a balance model of androgyny, in that non-sex-typed subjects showed greater resilience to recent life stress than did sex-typed subjects. The findings are discussed in terms of their implications for the study of life stress adjustment.  相似文献

Previous experiments with picture sorting and matching tasks have shown aphasics to give more deviant responses than controls when decisions require the identification of single features of concepts, whereas their responses are close to normal whenever decisions have to be based on the relative overlap of broad associative fields. The present experiment was designed to compare picture matching based on single features (property verification) with picture matching based on category membership (category verification). Fifty-five aphasics (14 amnesics, 18 Brocas, 13 Wernickes, 10 global aphasics) and 29 right-brain-damaged control patients served as subjects. Aphasics were poorer than right hemisphere controls on property as well as on category sortings, especially when the sorting criterion was not a dominant property of the object or when the object in question was not a typical member of the criterion category. Contrary to other studies, the "semantic distance" variable did not differentially affect Brocas as compared to Wernickes aphasics. Verbal labels denoting the sorting criterion and added to the picture presentation did not affect the performance of the right hemisphere controls but significantly improved that of the aphasics.  相似文献

This study investigated the relationship between articulation rate and memory span in a sample of 21 patients with early Alzheimer type dementia (AD), comparing their performance with 21 matched controls. Memory span was measured using auditorily and visually presented digits. The AD patients were moderately impaired in both conditions. Articulation rate was measured either by requiring subjects to read lists of random digits or repeatedly count from 1 to 10. The AD patients were able to read the digits as fast as the controls but were slower in the counting task. The measures of memory span and articulation rate correlated significantly for the controls but not for the AD patients, indicating that the normal association between articulation and memory span is disrupted. These results are discussed in relation to previous results and suggest that articulatory rehearsal processes in primary memory are unimpaired at the early stages of AD.  相似文献

The literature suggests that popularity may have different correlates depending on the ethnic, racial, and/or socioeconomic characteristics of the peer group. This study therefore investigated the relationship between peer popularity and academic achievement in low-socioeconomic status urban black children, a population in which this relationship had not previously been examined. Two hundred ninety-six children in grades 4, 6, and 8 completed three sociometric rating scales, indicating the popularity of each of their same-sex classmates as a workmate, playmate, and best friend. These ratings were subjected to a multivariate analysis of variance in which gender and academic achievement (high vs. low achievement test scores) were factors. Consistent with previous research, high achievement was associated with greater popularity as a workmate for an academic task at all three grade levels examined. Popularity as a playmate and as a best friend, however, was inversely related to achievement among fourth graders and unrelated to achievement among eighth graders. These findings suggest that, although high achievement may be recognized for its adaptive value in a work-related context, it may actually be something of a social liability among younger children choosing partners for social and athletic activities. The results support a conceptualization of popularity as a multidimensional construct and highlight the importance of the use of multiple measures.The authors express their appreciation to the children, parents, and staff of the Orleans Parish Schools for their cooperation and participation in the study and to Rex Forehand and Ben Lahey for helpful comments on the design and analysis.  相似文献

In a study of sexism and language 112 persons at a shopping mall were asked to read a paragraph about an achieving woman who was either given the title Miss, Mrs., or Ms., or not given a title. Persons receiving the paragraph with the Ms. title rated the woman as less honest. No effect of the title variation was obtained on a number of other rating dimensions. The results were interpreted as reflecting public acceptance of the use of the Ms. title.  相似文献

This case serves as a paradigm of concurrent treatment of a mother and child, where the central problem was one of separation-individuation. The nature of the child's presenting symptom of night terrors, the overinvolvement of the mother and the child, and the tendency of the child to withdraw from the outside world, all pointed to a child at risk for the more symptomatic development of school refusal and greater psychopathology. Since the treatment took place within a full service community mental health clinic, it was possible to provide psychiatric evaluation and consultation of both mother and child and the use of two therapists working collaboratively. With this method of treatment, the unfolding of both mother's and child's separation-individuation processes could be identified and utilized. Since she was an electively mute child who refused to come into the treatment room, another therapeutic tool became the use of the younger brother as a facilitator.  相似文献

A review of the literature on children's use of relative clause constructions reveals many contradictory findings. The suggestion is that some studies fail to take into account the two factors of embeddedness (role of complex noun phrase within the sentence) and focus (role of head noun in the relative clause). The experiment reported here attempted to reconcile the disparate findings and extend the range of constructions examined. 114 children between the ages of 3 and 7 served as subjects in a test of comprehension using an act-out procedure of 9 different relative clause sentences that exhaust the possible combination of 3 roles of the complex noun phrase in the sentence and 3 roles that the head noun plays within the relative clause (in each case, subject, driect object, and indirect object). All constructions were understood better with increasing age of the children sex and sentence set were nonsignificant variables. The results reveal a difficulty in ordering of the 9 types of construction that is in keeping with a prediction based on surface structure processing strategies.This research was supported by grant No. BNS73-09150 from the National Science Foundation to Professor Roger Brown.  相似文献
