Introduction: Evaluation in hospitals is a necessity in the way of promoting the health of the community and requires valid and reliability instruments. Therefore, the present study was conducted with the aim of developing and psychometrics "Evaluation Criteria for Health Promoting Hospitals Scale".
Methods: The present research is methodological. Initially, a comprehensive review of the research topics included documents, service providers at hospital management levels, all published library documents, and national strategic documents in the field of hospital health promotion and Social Security documents. The " Evaluation Criteria for Health Promoting Hospitals Scale" was then developed with 72 items. Face validity, content validity ratio, and content validity index were measured by a survey of 10 experts. Construct validity (factor analysis) was determined by distributing the scale between 272 samples. Reliability was measured by internal consistency method by calculating Cronbach's alpha coefficient with 15 participants and composite reliability. Data were analyzed in SPSS. 21 and LISREL.
Results: The " Evaluation Criteria for Health Promoting Hospitals Scale" was developed with 68 items, 11 components (in 3 structural, process and consequential dimensions). The ratio of content validity, content validity index and construct validity was confirmed. Reliability was performed by internal consistency method by calculating Cronbach's alpha coefficient and its value was 0.758 for structural dimension, 0.895 for process dimension and 0.924 for consequential dimension. 
Conclusions: The "Evaluation Criteria for Health Promoting Hospitals Scale” with 68 items, 11 components (in 3 structural, process and consequential dimensions), has a high validity and reliability. It is recommended to use the above scale to evaluate health promotion hospitals.
