Assessing the Reliability and Validity of an Instrument for Measuring Patient Use of Telemedicine in Light of the Technology Acceptance Model
Abstract Background:Telemedicine has been used as a supportive service to assure that quality healthcare services are provided in a timely manner. The growing use of telemedicine, especially for e-consultations, is increasing patient access to care, especially during pandemics or emergencies. However, a valid and reliable tool is needed to measure its use. This study aimed to evaluate the reliability and validity of patient acceptance of telemedicine, utilizing the dimensions of Technology Acceptance Model (TAM).Methods:The researcher designed an instrument based on TAM dimensions/principles. The instrument was distributed among 244 participants via an online link found in social media, such as Twitter and WhatsApp, from August 2020 to December 2020. Content validity and exploratory and confirmatory factor analysis were used to examine the construct validity, and Cronbach’s alpha test was employed to examine the reliability of the instrument.Results:A total of 244 participants in the study and 22 items or questions had a loading factor greater than 60. The assessment suggested 6 factors to explain the variation in the participant responses, with 75% of the variation being explained by these factors. The confirmatory analysis agreed with the explanatory factors, suggesting that the number of items and latent factors had a CMIN/DF equal to 3.021 and an RMSEA of 0.095, with a 90% CI (0.105 -0.086).Conclusion:The results of the study suggest that the measure shows acceptable validity and reliability.
