Objective: One of the major challenges in the implementation of the Picture Archiving And Communication System (PACS) is the attitudes of physicians towards the system. This study aims to design and assess the psychometric properties of a questionnaire for identifying the factors affecting the acceptance and use of PACS in Iran based on the Unified Theory of Acceptance and use of Technology (UTAUT).
Methods: This methodological study with cross-sectional design was conducted with the participation of 400 physicians working in hospitals affiliated to Isfahan University of Medical Sciences in 2019. Physicians were selected by stratified random sampling method with the probability proportional to size procedure. The questionnaire’s face validity, content validity, construct validity with exploratory factor analysis (EFA), test-retest reliability with intraclass correlation coefficient (ICC), and internal consistency with Cronbach’s alpha coefficient, were determined. The data were analyzed in SPSS.
Results: The face validity was 1.51-3.4 and the content validity index and content validity ratio ranged 0.6-1 in all factors. Twelve factors including performance expectancy, effort expectancy, social influence, facilitating conditions, computer self-efficiency, behavioral intention, technology optimism, problem solving, rationalized decision-making, horizontal integration, vertical integration, and presentation of health services to clients were extracted by conducting EFA, which explained 67.86% of the common variance. Cronbach’s alpha was obtained 0.92 and the ICC was 0.86 .
Conclusion: The designed questionnaire has good validity and reliability. It is recommended as a valid tool to evaluate the factors affecting the acceptance and use of PACS in Iran.
