A cross-sectional analysis of health literacy: patient- versus family doctor-reported and associations with self-efficacy and chronic disease

BACKGROUND: Adequate health literacy (HL) levels contribute to good health outcomes and successful disease self-management in patients with chronic disease. Hence, it is essential that family doctors recognize patients with inadequate HL in need of additional support. This study had two aims: (1) to assess and compare patient self-reported versus family doctor-rated HL estimates, and (2) to explore associations between patient-reported HL, self-efficacy and chronic diseases. METHODS: Participants in this cross-sectional survey were recruited through general practices in North Rhine-Westphalia, Germany. Patient self-reported HL was measured using the European Health Literacy Survey-16. Family doctor-rated HL was measured with an adapted version of this instrument. Using crosstabulations patient-reported and family doctor-rated HL estimates were compared for 346 patient-family doctor pairs. Associations between HL, self-efficacy and chronic disease were investigated using regression analyses. RESULTS: Patient-reported and family doctor-rated HL estimates were concordant in 38% of all cases. On average family doctors rated their patients’ HL lower than patients rated their own HL. The lower average family doctor ratings were more pronounced when patients were older, male and had more than one chronic disease. Female family doctors rated HL of male patients lower than their male colleagues. Patient reported HL had a significant positive association with self-efficacy. Mediation analysis provided support that self-efficacy acts as mediator between HL and the number of chronic diseases. CONCLUSIONS: Our study findings indicate a significant discrepancy between patients’ self-reported HL and externally rated HL by family doctors. A more systematic utilization of HL screeners might help reduce this discrepancy. At the same time, consideration should be given to enhancing communication training for family doctors and addressing critical HL skills in patient education.
