Personality and resistance to illness   总被引:2,自引:0,他引:2  
Personality was found significantly to mitigate the illness-provoking effects of stressful life events. Two groups of executives had comparably high degrees of stress over a 3-year interval, as measured by the Holmes and Rahe Schedule of Recent Life Events. One group (n = 86) suffered high stress without falling ill, while the other (n = 75) reported becoming sick after their encounter with stressful life events. Illness was measured by the Wyler, Masuda, and Holmes Seriousness of Illness Survey. Discriminant function analysis supported the prediction that high stress/low illness executives show, by comparison with high stress/high illness executives, more control, commitment, and interest in change as a challenge.  相似文献

Groups of adolescents of retarded and borderline intelligence, ranging in IQ from 44 to 80 and in mean MA (mental age) from 8 to 12 yr, and groups of nonretarded children ranging in mean MA from 6 to 12 yr, were given logical problem solving tasks. In the nonretarded groups, on a one-bit problem only the kindergarten children (mean MA = 6 yr) failed to perform above chance, and were not tested further. On a two-bit problem, only the first graders (mean MA = 7 yr) failed to perform above chance.Conversely, in the low IQ groups, only the borderline group (mean MA = 12 yr) performed reliably above chance on the one-bit problem, and none performed above chance on the two-bit problem. There is a profound deficiency in low IQ individuals on certain tasks requiring logic and foresight, and MA markedly over-estimates their performance relative to the performance of nonretarded individuals.  相似文献

This study investigated social-psychological characteristics of disadvantaged persons in employment training. Participants (N=115) furnished information about their psychological resources (internality and learned resourcefulness), social support, and job procurement self-efficacy when they entered employment training programs. Self-efficacy was assessed again approximately 3 weeks after termination from training. It was expected that psychological resources and social support would be associated and that they would predict job procurement self-efficacy at follow-up. Psychological resources and social support were significantly related. Social support, and particularly reassurance of worth, were significant predictors of participants’ efficacy expectations at follow-up. Implications for employment preparation are discussed, and directions for future research are suggested.  相似文献

Several studies have suggested that chronically ill adults who receive overprotective care are more depressed and less motivated in rehabilitation therapy. However, for this area of research to proceed, a standard definition and measurement of perceptions of overprotection are needed. In the present study, long and short forms of a scale (the OPSA) to assess perceptions of being overprotected in chronically ill adults were developed. The scale's psychometric properties were tested with a sample of 161 community-dwelling older adults. It was found to have good internal reliability, to correlate highly with an established retrospective measure of overprotection in adults, and to be distinct from ratings of quantity and quality of social support. As expected, overprotection was associated with poorer adjustment: Respondents who felt overprotected were more depressed.  相似文献

A probabilistic choice model is developed for paired comparisons data about psychophysical stimuli. The model is based on Thurstone's Law of Comparative Judgment Case V and assumes that each stimulus is measured on a small number of physical variables. The utility of a stimulus is related to its values on the physical variables either by means of an additive univariate spline model or by means of multivariate spline model. In the additive univariate spline model, a separate univariate spline transformation is estimated for each physical dimension and the utility of a stimulus is assumed to be an additive combination of these transformed values. In the multivariate spline model, the utility of a stimulus is assumed to be a general multivariate spline function in the physical variables. The use of B splines for estimating the transformation functions is discussed and it is shown how B splines can be generalized to the multivariate case by using as basis functions tensor products of the univariate basis functions. A maximum likelihood estimation procedure for the Thurstone Case V model with spline transformation is described and applied for illustrative purposes to various artificial and real data sets. Finally, the model is extended using a latent class approach to the case where there are unreplicated paired comparisons data from a relatively large number of subjects drawn from a heterogeneous population. An EM algorithm for estimating the parameters in this extended model is outlined and illustrated on some real data.The first author is supported as Bevoegdverklaard Navorser of the Belgian Nationaal Fonds voor Wetenschappelijk Onderzoek.

Bowen's differentiation of self construct is examined through a test in two studies of the hypothesis that people select partners at similar levels of differentiation of self. One study used a sample of married couples and the other a sample of dating and engaged couples. The studies used different instruments for determining differentiation of self. Three data analysis procedures—correlations, t-tests, and the degree of similarity procedure—provided conflicting evidence for the similarity hypothesis. Results are discussed as they pertain to statistical analysis issues using related individuals and to Bowen family systems theory and the use of this theory in clinical practice.  相似文献

The present study aimed to describe how a volunteer peer support service assists women with breast cancer, and provides guidelines for practitioners in the development and implementation of such programmes. A two‐phase evaluation of a breast cancer peer support program was undertaken to describe important attributes of the peer support intervention, the impact of the volunteer visit on women's self‐reports of anxiety, and key indicators of a successful volunteer visit. Phase 1 included focus groups with 57 women previously treated for breast cancer. Phase 2 included a survey of 245 women also treated previously for breast cancer and visited by a Breast Cancer Support Volunteer. The key aspect of the peer support process was the bond of common experience leading to a decrease in social isolation, an increase in optimism about the future and reassurance about personal reactions and femininity. It is recommended that peer support programmes should aim to time support visits to coincide with the time when patient support needs are highest, that volunteers need to be recruited from a range of backgrounds and matched to patients most similar to them in way of life, and that peer support services should be embedded in a broad network of community support services.

ABSTRACT Scales were constructed to measure perceived control over controllable events (realistic control) and perceived control over uncontrollable events (unrealistic control). Internal reliability, test-retest reliability, and discriminant validity of both scales were adequate. Study 1 measured perceived personal control over hassles that judges rated on general controllability. For hassles very high in controllability, perceived personal control was related to belief in realistic control but not to belief in unrealistic control; for hassles very low in controllability, perceived personal control was related to belief in unrealistic control but not to belief in realistic control. Study 2 showed that participants high in unrealistic control belief (but not those high in realistic control belief) persevered more on a task that was in part uncontrollable. Study 3 showed that the combination of low realistic control belief and high unrealistic control belief predicted poorer future health, particularly for participants who have reported the experience of many negative events and/or hassles. The conditions under which unrealistic control results in maladaptive outcomes are discussed.  相似文献

A quasi-experimental replication of an intervention for promoting tobacco control policies in Northwest Indian tribes is described and the process of intervention including issues of collaboration among research institutions and Indian organizations is discussed. The policy intervention was evaluated using a pretest-posttest design wherein 20 tribes that had served as wait-list controls now received the intervention. The intervention comprised a tribal representative attending a kickoff orientation; follow-up visits to the tribes; distribution of tobacco policy workbooks; and phone call consultations. Policy status and stringency were assessed by means of telephone interviews with two key contacts per tribe, and by a count of enacted policies. There were significant pre-post changes in the primary outcome measure, a composite summary score of tobacco policy stringency, and changes were also reflected in enacted policies. The intervention effects observed were similar to those found in the prior randomized trial and suggest a robust, disseminable intervention. Much of the success achieved was attributed to the role of an Indian organization in planning the project and implementing the intervention and evaluation protocols.  相似文献
