Personality and resistance to illness

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.     

Performance of retarded adolescents and nonretarded children on one- and two-bit logical problems

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.     

The Relationship of Psychological Resources and Social Support to Job Procurement Self-Efficacy in the Disadvantaged1

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.     

Perceptions of Overprotection in III Adults1

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.     

A thurstonian pairwise choice model with univariate and multivariate spline transformations

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.

FEMINISM AS LIFE RAFT

We looked at relationships between academic women's feminist identity and their perceptions of discrimination. From a sample of self-labeled feminist professors of psychology who had participated in the Feminist Teaching Project, we examined previously transcribed interviews and also collected new, auxiliary information. We expected to find that our respondents would view feminism as both provoking discrimination and helping them cope with discrimination. We found that experiences with gender discrimination were common among our sample, but that feminism in isolation was not perceived by our respondents as a provocation for problems. Rather than making it hard for women to swim in academic waters, feminism seemed to serve as a life raft for many professors.     

Locus of control predicts appraisals and cardiovascular reactivity to a novel active coping task

These two studies investigated the influence of dispositional locus of control (LOC) on subjective and physiological responses to a novel laboratory stressor task. Across two studies, 64 healthy undergraduate students, ages 18-22, completed Levenson's (LOC) scales for internal, powerful others, and chance prior to performing a video-game task. Participants rated pretask and posttask stressfulness and coping ability (i.e., measures of primary and secondary appraisal). Cardiovascular measures (heart period, HP; preejection period, PEP; respiratory sinus arrhythmia, RSA; cardiac output, CO; systolic blood pressure, SBP; diastolic blood pressure, DBP & total peripheral resistance, TPR) were recorded during 4-minute baseline and 4-minute stressor task periods. The internal LOC factor predicted pretask reports of coping ability as well as posttask reports of stressfulness. In contrast, the powerful-others LOC factor predicted cardiac changes (HP, PEP, and RSA) during the task but not cardiac output or any other vascular change measure. These results underscore the importance of using the three subscales of the Levenson LOC to assess relationships between dispositional LOC and the response to stressors because self-reported appraisals of a task are predicted by a different component of dispositional LOC than are task-related cardiovascular functions.
