The purpose of this paper was to validate the Nurse Task Computer Use (NTCU) scale as a measure of the impact of computer use on tasks performed by nurses. It was expected that evaluation of a computer system by tasks is a better measure of nursing satisfaction. We used four strategies to accomplish validation. Initially, we used taxonomy of nursing interventions developed by Susan Grobe as a basis for identifying tasks. Next, using factor analysis, the results of the NTCU was compared to two validated user satisfaction scales. The third validation strategy consisted of comparing responses to the survey with interview findings for similarity, additional responses, and reoccurring patterns. Finally, findings from the results of the NTCU were compared to the Computers in Medical Care values survey. Results generally supported the validity and reliability of this instrument.
