Aims: This research aimed at designing and psychometric properties of a questionnaire for health-worker skills evaluation to obtain a self-care program for pre-diabetic patients. Instrument & Methods: The questionnaire's psychometric properties were evaluated utilizing face validity by ۱۵ health workers, content validity was evaluated by ten experts (۵ health education and health promotion experts, three diabetes experts, and two general practitioners), and construct validity, internal consistency, and stability were assessed by ۴۰۰ health workers who were randomly selected.  Findings: Due to the results of investigating the texts and interviews, the initial questionnaire, including ۵۴ phrases, was presented. In the face validity section, eight expressions were removed quantitatively. Then, in identifying content validity, three other words were deleted, and the questionnaire was reduced to ۴۳ phrases in general. This questionnaire's exploratory factor analysis revealed four factors: self-efficacy, attitude, reinforcing factors, and enabling factors. These four factors explained ۵۷.۵۱% of the total variance of the test. The confirmatory factor analysis results also confirmed the factors of the PRECEDE-PROCEED model. Cronbach's alpha and intra-cluster correlation index for questionnaire structures ranged from ۰.۸۷-۰.۸۸ and ۰.۸۷-۰.۸۸, respectively. Conclusion: The designed questionnaire has good validity and reliability.
