Perceived Efficacy in Patient-Physician Interaction Questionnaire (PEPPI) is range of 5 to 25; higher scores indicate that the participant has higher self-efficacy in patient-physician interactions

^aUnivariate variables with P values < 0.05 were entered into the multiple linear regression

^bNominal variables were entered into analysis using dummy coding

^cP values are bold where they are less than the significance level of 0.05
