Several measures have been developed to evaluate the health literacy; however, have shown limited capacity in differentiating between health literacy and the basic literacy. To address self-confidence in health information, we developed and validated a questionnaire for measuring health-related self-efficacy.

Six items were developed in reference to previous studies on self-efficacy and health literacy. The study was conducted as a part of ‘Validation of Indices and Questionnaires for Optional Survey and Bank System for Community Health Survey’ in 2013. Responders were randomly selected from six districts among the survey subjects.

A total of 358 responses were analyzed to validate the scale. Inter-item correlation coefficients ranged between 0.23 and 0.64. Unidimensionality was confirmed since single factor was with the eigenvalue above 1.0 in scree plot. Cronbach alpha coefficient was 0.75. Confident responses in Item I and II were higher in college-graduated responders. Married persons responded less confident in Item I and III. Confident responses in Item I and II were inversely correlated with self-rated poor health. Correlation test between HrSES and EQ-5D revealed that confident responses in Item III and IV were inversely correlated with pain/discomfort and anxiety/depression. In ItemI and IV, responders aged over 50 reported lower confidence than those aged less than 40 (P < 0.001 for both). Age group over 60 showed lower level of confident response in the Item II (P < 0.001) and IV (P = 0.007).

Base on this study, HrSES is suggested to be an easy and reliable tool for the measurement of health-related self-efficacy in the community health survey.
