Illness intrusiveness explains race-related quality-of-life differences among women with systemic lupus erythematosus
Bibliographic record
Abstract
Our objective was to investigate whether quality of life in systemic lupus erythematosus (SLE) differs across ethnoracial groups and to identify factors that may explain race-related differences. Self-administered questionnaire data from 335 White, 40 Black, and 30 Asian women with SLE were obtained from a multi-center database. Measures assessed illness intrusiveness, psychological well-being, depressive symptoms, musculoskeletal pain, and learned helplessness. Extent of SLE disease activity was indexed by self-reported functional-system involvement. Educational attainment was indicated by number of years in school. Principal-components analysis reduced the four psychosocial measures to a single factor score. This represented psychosocial well-being In path analysis. Psychosocial well-being differed significantly across the three groups, with Whites reporting the highest, and Blacks the lowest, levels. Path analysis indicated that illness intrusiveness accounted for this race-related difference. Although disease activity was significantly associated with psychosocial well-being, it did not differ across ethnoracial groups. Illness intrusiveness and educational attainment emerged as independent mediators of the race-related difference in psychosocial well-being. We conclude that race-related quality-of-life differences exist among women with SLE and are mediated independently by illness intrusiveness and educational attainment.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
