Abstract:: Abstract: Objective To compile and validate a scale (HORPAS) for hospital managers and medical personnel to evaluate hospital occupational radiological protection ability. Methods HORPAS was compiled by an appointed expert panel based upon the latest released national standards and relevant academic literatures. A questionnaire survey was conducted among 307 radiologists for evaluating the reliability and validity of the scale. Results HORPAS was composed of 6 dimensions, with a total of 24 items. The dimensions included radiation protection regulations, radiation protection health monitoring for medical personnel, equipment maintenance and protection distance, radiation dose detection equipment, personal protective materials and surgical operation requirements. The results showed that I-CVI=0.90, S-CVI/Ave=0.90, indicating a good content validity, and that Cronbachs α=0.818, indicating a good reliability. Exploratory factor analysis showed that the factors could explain 55.70% of the total variance, and confirmatory factor analysis showed that [χ2]=276.318, df=237, [χ2]/df=1.166, RMSEA=0.033, CFI=0.913, indicating a good construct validity. Conclusion HORPAS which had a good validity and reliability can be used as a reliable and valid instrument for healthcare administration department and hospital managers to evaluate hospital occupational radiological protection ability.
