A review of questionnaires used for the assessment of telemedicine.

We analyzed a total of 71 articles. We found that only 16 studies used three validated questionnaires. The remaining 55 studies used non-validated questionnaires. Non-validated questionnaires had a high variability in length and used Likert scales, binary responses, multiple choice, and open-ended answers. We found only eight studies in which the authors gave a reason for resorting to designing their own questionnaires. This review reveals insufficient standardized survey questionnaires to be used for the assessment of audiovisual telemedicine encounters. Future research initiatives should focus on developing a standardized and validated instrument well accepted by researchers.
