Current advances in technology have enabled the development of a computer-based questionnaire that provides advantages over the paper-based mode of administration, such as automatic data entry, storage and calculations. However, before implementing a computer-based questionnaire, its equivalence with the original paper-based questionnaire must first be demonstrated. The purpose of this study was to evaluate the measurement equivalence of the computerized Diabetes- Specific Quality-of- Life questionnaire ( cD- QOL) with its original paper-based counterpart. A two-period crossover design was used in this study. The measurement equivalence was evaluated using quadratic weighted kappa coefficients, intraclass correlations and Cronbach's alpha comparisons. The cD- QOL was equivalent to its original paper-based counterpart. Participants preferred the cD- QOL over the paper-based questionnaire and reported that it was easy to use. [ABSTRACT FROM AUTHOR]
