Development and Validation of the Saudi Telehealth Acceptance Scale Based on the Unified Theory of Acceptance and Use of Technology.

Background: Telehealth is in early stages in the Kingdom of Saudi Arabia (KSA). Identifying barriers to using telehealth is an essential step prior to its implementation; however, no theoretically based scales exist for the same purpose. Objective: To design a theory-based scale capable of measuring telehealth users' perceptions of benefits, barriers, and social influence in the KSA. Methods: The Saudi Telehealth Acceptance Scale (STAS) was constructed based on the Unified Theory of Acceptance and Use of Technology and its content validity was determined by eight experts using the modified Delphi process. Only items with a content validity index score of ≥0.83 were chosen. Finally, the face validity of the questionnaire for healthcare professionals, which was in English, was determined by eight healthcare professionals, and for the patient version, which was in Arabic, by six patients. Results: Initially, 37 items were identified; however, after Round 1, 29 items remained and after Round 2, 24 items were included in the STAS for both healthcare professionals and patients. In the healthcare professionals scale, there were 7 performance expectancy (PE) items, 6 effort expectancy (EE) items, 3 social influence (SI) items, 4 facilitating conditions (FC) items, and 4 behavioral intention (BI) items, while in the scale for patients, there were 9 PE items, 4 EE items, 3 SI items, 4 FC items, and 4 BI items. Conclusions: The two new scales showed evidence of content and face validity. The significance of the two scales is that they were both designed in the context of the healthcare system in the KSA and could provide standardized data collection tools to measure the acceptance of telehealth among HCPs and patients.
