This is the first report of the Twin Mom Study, an investigation of three hypotheses concerning influences on maternal adjustment. These hypotheses concern the role of the marital and parent-child relationships in mediating genetic influences on maternal adjustment and on the importance of the mothers' marital partners as a specifiable source of influences on their adjustment not shared with their sisters. The study's sample of 150 monozygotic (MZ) twins and 176 dizygotic (DZ) twins was drawn randomly from the Swedish Twin Registry and is, with some small exceptions, likely to be representative of women in the Swedish population. The sample included the marital partners of these twins and their adolescent children. Self-report and coded videotapes were a source of information about family process. Results reported in this first report focus on comparability of American and Swedish samples on scales measuring psychiatric symptoms, and on an analysis of genetic and environmental influences on nine measures of mothers' adjustment. Results suggest comparability between the US and Sweden. Genetic influences were found for all measures of adjustment, particularly in the psychological manifestations of anxiety and for smoking. The pattern of findings also underscored the importance of influences unique to each sibling within the twin pair, thus focusing attention on the potential role of marital partners in maternal adjustment. Results also suggested that experiences shared by the twin sisters, experiences unrelated to their genetic similarity, may influence their fearfulness and alcohol consumption. Our model did not include these influences and thus must be amended.  相似文献

The objectives of the current study were (1) to assess adjustment in patients following a first myocardial infarction (MI) at 9 months compared with 4-6 weeks post-MI, (2) to examine the availability of and satisfaction with social support over time, and (3) to determine separate baseline psychosocial predictors of recurrent cardiac events. A questionnaire assessing post-traumatic stress disorder, anxiety, depression, health complaints, and social support, was distributed to consecutive patients 4-6 weeks and 9 months post-MI. Prior to assessment at follow-up, 8 (7%) of 112 patients had dropped out, and two had died due to cardiac causes. Objective clinical measures were obtained from medical records. There was an improvement in somatic and cognitive symptoms at follow-up, but no change in symptoms of arousal, depression, and anxiety. Half of the patients were afraid of a recurrent MI. There was a significant decrease in social support between baseline and follow-up, and lower social support at baseline was associated with a 10% increased risk of recurrent cardiac events at follow-up (OR: 0.90; 95% CI: 0.84 to 0.97) adjusting for all other variables. Some patients still experienced difficulties with psychosocial adjustment 9 months post-MI despite a reduction in somatic and cognitive symptoms. Social support decreased over time, which may have serious prognostic implications; lower social support at baseline was an independent predictor of recurrent events at 9 months. An important step for future research will be to investigate how social support can be enhanced in patients at risk.  相似文献

The in‐group preference and self‐concepts of urban Aboriginal‐Australian and Anglo‐Australian children have never been compared, nor their relationships to teachers' evaluations of academic performance. In this study, 60 Aboriginal (primarily local Nyoongah) and 60 Anglo children aged 6–12 years were tested on in‐group preference; children aged 8+ were tested on self‐concept. Also, their teachers evaluated them on their general academic performance. Results indicated that Anglo children showed greater in‐group preference and scored higher on teacher evaluations than Aboriginal children, although there was no difference on self‐concept. No correlation existed between in‐group preference and self‐concept. It was concluded that the problems faced by Aboriginal children are only likely to be alleviated by a great deal of structural change. Copyright © 2000 John Wiley & Sons, Ltd.  相似文献

Two studies examined the reduction of triggered displaced aggression (TDA) via bottom‐up processing modes of de‐categorization. Participants were provoked by the experimenter and then interacted with an ostensible out‐group member who either did or did not provide a second (triggering) provocation. Study 1 compared TDA toward a triggering out‐group member who had previously been either differentiated from the out‐group, made the focus of self‐other comparison, or was in a no‐information control condition. As predicted, both differentiation and self‐other comparison reduced aggression relative to the control condition. Study 2 examined the effect of negative self‐disclosure from the out‐group target, and contrasted its effects with both self‐other comparison with a negative other, and a no‐information control condition. As predicted, triggered participants in the negative self‐disclosure condition aggressed less than those triggered in the negative self‐other comparison or no‐information control conditions. The liking induced by self‐disclosure mediated its aggression‐reducing effect. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献

Burt (2002) raises several interesting points in his commentary on our paper. However, the most important difference between his and our studies, the design, was not addressed. We argue that our experimental approach makes more realistic assumptions for causal interpretation. The other points that he raises—the relationship between practical and statistical significance, the verbs used by our participants, and definitions of memory—are all discussed.

Although social perception research has been carried out across a number of diverse domains, to the best of our knowledge, studies have not directly assessed the relationship between attitudes toward the out‐group and perceptions of community support for those attitudes. In the present research, we report the findings of a study conducted in Western Australia using data collected from 653 participants from three different locations. The main thrust of our study was the accuracy of beliefs about consensus as it related to attitudes toward two marginalized groups: Indigenous Australians and asylum seekers. With respect to their attitudes toward these two groups, our respondents were placed in seven categories corresponding to their responses to our seven point attitude scales. Three main findings emerged. First, respondents at all seven levels overestimated community support for their views with respect to both Indigenous Australians and asylum seekers. Second, as respondents in both groups became more rejecting, their estimates of community support progressively increased in a linear fashion. Third, respondents in the more negative categories were significantly less accurate in their estimates than those in the more positive categories. How these findings might contribute to programmes designed to reduce prejudice is discussed. Copyright © 2008 John Wiley & Sons, Ltd.  相似文献

Abstract

This paper examines the relationship between quantitative and qualitative indicators of social support and anxiety. depression and use of health services in a sample of 37 wives of myocardial infarction (MI) patients. In a prospective design, the wives were interviewed during the acute phase of the illness, three months and 10 years post index-MI. Congruent with previous research, the quantitative aspect of social support, defined as number of persons giving help, was unrelated to adjustment, whereas qualitative aspect of social support, defined as the wives' dissatisfaction with social support, was associated with depression and use of health services. The observed association indicated, however, an effect in the opposite direction of the social support model. The findings were unexpected and may be due to a small sample. An alternative explanation is that long-term relationship between depression and social support is more complex, and more long-term studies are needed in this field.  相似文献

Memory impairment following closed-head injury (CHI) in children is well documented. Characterization of the memory deficits of children with CHI could contribute to the prediction of academic performance and rehabilitation of these children. Twenty-five children who sustained closed-head injury and 25 matched controls were administered the Rey Auditory Verbal Learning Test (AVLT). The advantage of this memory test is that a number of memory components are measured simultaneously, thus enabling us to study the relations between different aspects of memory within the same patient sample. The findings indicate that the Rey AVLT is a good test for characterization of impaired verbal memory in children following CHI. Transformation of scores derived from the Rey AVLT to Z-scores enables us to determine the relative effect of CHI in children on different memory scores. Raw scores were more vulnerable than relational ones, derived as the difference between two raw scores (e.g., learning, Trial 5?1), to closed-head injury in children, and scores reflecting word span were the least vulnerable. The results are discussed in terms of the possible contribution of the frontal lobes, which are frequently affected in closed-head injuries, to memory performance.  相似文献
