Evaluation of a New Performance-Based Health Literacy Measurement Tool for Individuals With Chronic Airways Disease
Bibliographic record
Abstract
BACKGROUND: Low health literacy is a global challenge. Health literacy is positively correlated with chronic airways diseas e desirable outcomes. Despite the importance of health literacy in disease management, current health literacy measurement tools are suboptimal. As part of a multi-stage project to develop a performance-based, disease-specific Vancouver Airways Health Literacy Tool (VAHLT) for individuals with chronic airways disease, this study assessed the relationships between the VAHLT scores and characteristics of patients with chronic airways disease. The primary aim of the study was to provide preliminary evidence of construct validity of the VAHLT. METHODS: A cross-sectional study design was applied. Study subjects were recruited from 6 specialty care clinics to complete the VAHLT measurement tool. Demographic and clinical data, including quality of life and disease control, were collected via validated questionnaires. The study subjects also completed a spirometry test. Inferential analysis was conducted by using mean difference testing and correlational methods. RESULTS: A total of 320 subjects were recruited, and, after imputing missing data, 315 were ultimately analyzed. The subjects were predominantly women (61%), white (83%), had a post–high-school education (74%), and a mean ± SD age of 65.2 ± 13.2 y. Age was significantly negatively correlated with the VAHLT scores ( P = .004); the subjects with a post–high school education had significantly higher VAHLT scores than those with a high school education or less ( P < .001). No significant sex or ethnicity related differences in VAHLT scores were observed. For clinical outcomes, no significant differences were found between the VAHLT scores and disease severity or measures of quality of life and asthma control. CONCLUSIONS: We report a chronic airways disease–specific health literacy measurement tool developed with the involvement of patients and professionals. Age and education were highly correlated with health literacy, which emphasizes the importance of addressing these factors in health literacy interventions among patients with chronic airways disease.

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.
