Abstract
The objective of this study was to compare two modes of administering a brief dietary fat screener and a food behavior questionnaire: paper-and-pencil and computerized touchscreen video. Fifty-four participants, having either diabetes or heart disease, were randomized to complete the computerized versions first, followed by the paper-and-pencil versions 1 week later, or the reverse. Results from the computerized touchscreen estimates were very similar to the paper-and-pencil group means for both fat intake and behavior scores. No significant differences were found for either main effects or interaction of mode with order of administration. Correlations between the two formats ranged from .83 to .94 (median = .89; all ps <.0001). The computerized touchscreen versions of both instruments were comparable and more efficient methods of assessment. The advantage and disadvantages of each modality are discussed.
