How a chronic environmental stressor can interfere with the buffering effects of social support by eroding social support was analyzed in this prospective, longitudinal study. A classic buffering effect of support was found after 2 months of exposure to the stressor, household crowding. Crowded residents with low perceived support had greater increases in psychological distress than did crowded residents with high perceived support. However, after 8 months exposure the buffering effect disappeared. Moreover, greater crowding had become directly associated with lower support, which in turn was associated with greater increases in psychological distress. All analyses controlled for prior distress. Under some types of chronic stress, the buffering effects of social support may be short-lived because the stressor eventually erodes social support.  相似文献

This study tested structural relationships within a model proposed to explain the manner in which self-esteem changes are associated with exercise experiences. As initially assessed by self-efficacies (EFFs) specific to physical tasks within a training program, we postulated that competence can generalize to feelings of global self-esteem (SE) through an intervening construct of perceived physical competence (PC). Three measures of EFF and two each of PC and SE were administered to 145 people in their mid- to late adulthood. Confirmatory factor analysis examined orthogonal and oblique versions of three measurement models and identified three distinct but correlated factors, each assessed by its hypothesized indicators. Alternative structural equation models were specified and tested using both normal and nonnormal estimation procedures. The proposed model provided the most parsimonious fit and explained 29% of the variance in SE. Confirmation of its structural relationships provides preliminary validity for model use in examining the manner in which exercise experiences influence levels of self-perception.  相似文献

Previous work with the Geriatric Hopelessness Scale (GHS; Fry, 1984, 1986) suggests that it may be a useful measure of pessimism for a variety of domains among elderly persons. One hundred seven community-residing aged persons were individually administered the GHS and a variety of personality and cognitive functioning measures in an effort to further refine and validate the GHS. Results suggest very modest internal consistency and a poorly defined factor structure for the GHS, in contrast to earlier findings. Although the GHS failed to differentiate elderly persons by age, it was nonetheless related to self-esteem, depression, self-rated health, internality, morale, and life satisfaction. Taken together, these data indicate that the research and clinical utility of the GHS with community-residing aged persons may be more limited than previously believed.  相似文献

Accuracy in the judgment of in-group and out-group variability   总被引:2,自引:0,他引:2  
The accuracy of in-group and out-group variability judgments was examined by comparing those judgments with the variability of self-ratings provided by random samples of group members. Following Park and Judd (1990), perceptions of both group dispersion and group stereotypicality were examined. Accuracy was examined both by within-subject sensitivity correlations and by simple discrepancies between perceived and actual variability estimates. In-group-out-group differences in sensitivity were shown, particularly for judgments of stereotypicality. These differences were related to differences in the degree to which out-group variability is underestimated relative to in-group variability (i.e., the out-group homogeneity effect). Out-group stereotypicality judgments were overestimated, supporting the view that out-group stereotypes are overgeneralizations. Whether dispersion judgments were over- or underestimated depended on their measurement.  相似文献

Seven studies investigated the cognitive structure of social relationships exhibited in the patterns of substitutions that occur when people confuse a person with another. The studies investigated natural errors in which people called a familiar person by the wrong name, misremembered with whom they had interacted, or mistakenly directed an action at an inappropriate person. These studies tested the relational-models theory of A. P. Fiske (1990b, 1991) that people use 4 basic models for social relationships. All 7 studies provide support for the theory; Ss tend to confuse people with whom they interact in the same basic relationship mode. In addition, Ss confuse people of the same gender. Other factors (age, race, role term, similarity of names) generally have smaller, less reliable effects, indicating that the 4 elementary modes of relationships are among the most salient schemata in everyday social cognition.  相似文献
