The purpose of this study was to develop a reliable questionnaire to assess the effectiveness of the healthy restaurant program, which was implemented by Seocho-gu District in Seoul. Evaluation indices were deduced from the logic model of the healthy restaurant program. The questionnaires consisted of three sections (process evaluation, outcome evaluation, and general characteristics) for restaurateurs and customers who were participating in the program or not. To validate the questionnaire, 133 restaurateurs and 246 customers were sampled using convenient methods. Data were collected by interviews. Reliability was tested by Cronbach’s alpha coefficient. The alpha coefficient for restaurateurs was 0.75-0.99 for the process and 0.79-0.97 for the outcome evaluation questions. The alpha coefficients for customers were 0.76-0.92 for the outcome evaluation questions. Face and content validity were examined for all questions, and construct validity was tested for latent variables. We are confident that more accurate and significant information will be collected using this questionnaire.
