Note: Dataset without imputation is the original data. Factor 1 = Technology Use Expectancy and Intention. Factor 2 = Technology Use Anxiety. Factor 3 = Technology Use Self-Efficacy. Factor loadings are equivalent to standardized regression coefficients between scale items and factors. Internal consistency reliability for the total scale is 0.91 for no imputation, and 0.89 for both single and multiple imputation. Internal consistency reliability is 0.95, 0.90, and 0.85 for Factors 1, 2, and 3, respectively for no, single, and multiple imputation. Root Mean Square Residual = 0.035 and Kaiser-Meyer-Olkin Measure of Sampling Adequacy = 0.93 for without imputation (original), single and multiple imputation
