Objective: To examine whether patient participation in medical consultations have differing effects on self-efficacy and diabetes control by the level of patient communicative health literacy (CHL).
Methods: Participants were 143 outpatients with type 2 diabetes at a university-affiliated hospital. Patient CHL was measured using a newly developed self-rated scale of health literacy. Patient perceived participation in medical consultations and self-efficacy of diabetes self-care were assessed using the self-reported questionnaire. Patient clinical characteristics were obtained from electronic medical records.
Results: Both patient CHL and perceived participation were related to greater self-efficacy and decreased HbA1c at the 3-month follow-up. Patient CHL had a moderating effect on the relationship between perceived participation and self-efficacy. Patients with lower CHL reported greater self-efficacy when they actively participated in patient-physician communication, whereas this relationship was less evident among patients with higher CHL.
Conclusions: The examination of patient CHL levels may provide a better understanding of the potential barriers to patients' self-management of disease.
Practice implications: The benefit of active participation may be greater among patients with lower CHL who are likely to have greater difficulties in communicating with the physician, yet tend to rely on the physician as the sole source of health information.
