Abstract

This dissertation explores patient trust in their physician and its impact on telemedicine. Telemedicine is using any technology to remotely communicate with a healthcare professional. The first study explores patient trust in their physician by validating the Wake Forest Trust in Physician scale for use in telemedicine research. The original (TIP) scale consists of 10 items and measures four of the five dimensions of trust: Fidelity, Competence, Honesty, and Global Trust. The final validated scale for telemedicine use (T-TIP) consisted of 12 items measuring three subscales: trustworthiness, interpersonal skills, and confidentiality. Study two explores the relationship between patient trust and delivery mode (telemedicine versus traditional interactions). The results from Study 2 indicate that patients trust their physician more in the telemedicine interaction than in the traditional interaction. There was also an effect of location, ethnicity, and frequency of doctor visits on patient trust. Study three delves further into the relationship between patient trust and telemedicine by examining the impact of communication mode on patient trust. Additionally, study three explores the relationship between usability and trust. There was no difference in patient trust scores between text and verbal communication. However, study three did find that as perceived usability of the interface increases, patient trust in their physician also increases. Also, this study found that the text interface had a higher fixation rate and shorter fixation duration than the video interface, indicating that the text interface had less cognitive load. These studies not only provide a tool for measuring patient trust in their telemedicine physician but also demonstrate that there is an impact of patient trust on telemedicine. The fact that patient trust in their physician is higher in telemedicine means that telemedicine could be used to increase patient participation in their own healthcare. Additionally, the relationship between usability and patient trust could be used to increase telemedicine use.
