Psychological stress and the fibrositis/fibromyalgia syndrome.

The relationship of stress and social support to the fibrositis/fibromyalgia syndrome (FS) was investigated by administration of 4 questionnaire instruments to 28 patients with FS, 20 patients with rheumatoid arthritis (RA) and 28 pain-free normal controls. FS showed higher levels of stress as measured by daily "hassles" than did RA or controls. However, on a measure of major life stress, they reported lower levels. No differences were found between groups with regard to daily "uplifts" or social support. Correlations between those measures of stress and social support with their scores on the Arthritis Impact Measurement Scale showed that the Hassles Scale was significantly related to the AIMS Psychological component.

Development and initial validation of a dual-language English-Spanish format for the Arthritis Impact Measurement Scales.

Language, cultural, and educational barriers complicate efforts to validate health status questionnaires that have been translated into Spanish. To overcome these problems, a prototype dual-language format was developed for the Arthritis Impact Measurement Scales. Validity testing with 72 patients diagnosed as having rheumatoid arthritis indicated high levels of test-retest reliability, item-to-scale internal consistency, and construct validity for both Anglo and Hispanic subjects. A technique for developing and pilot-testing a questionnaire written in a regional Spanish dialect is described. Linguistic considerations, questionnaire design, and other applications are discussed in light of the results obtained.

An approach to developing a valid Spanish language translation of a health-status questionnaire.

This article discusses methodological issues confronting health professionals using questionnaires to study health care variables among populations with limited literacy in English, and suggests techniques for minimizing problems that plague questionnaire-based research among these populations. A recent effort to validate a questionnaire for Rheumatoid Arthritis patients in South Texas is used to illustrate pitfalls and potential solutions.

Illness representations: a prototype approach.

Two experiments tested the hypothesis that laypeople cognitively organize and recall information about physical symptoms according to prototyped conceptions they have of physical diseases. Based on pilot studies that identified the extent to which subjects associated specified symptoms with specific diseases, symptom sets were assembled to vary in the extent to which the symptoms were perceived to be associated with (to be prototypical of) a given disease. Experiment 1 asked subjects to indicate whether a given set of symptoms indicated a disease and, if so, which one. Experiment 2 tested subjects' recall for symptom sets varying in prototypicality for given diseases and also tested the effects on recall of giving subjects a diagnosis. Results of both experiments support the prototype hypothesis that information about physical symptoms is organized and processed according to people's preexisting beliefs about the association between particular symptoms and diseases. Implications for illness behavior and help seeking are discussed.

Discussion effects on racial attitudes.

We predicted that discussion would enhance dominant group values, leading to increased polarization between homogeneously composed groups of high-, medium-, and low-prejudice high school subjects. In an experimental condition, group members made individual attitude judgments, discussed them, and remade judgments. Control groups discussed irrelevant materials before responding again to the attitude items. As predicted, discussion of the racial attitude items with others having similar attitudes significantly increased the gap between high- and low-prejudice groups.
