The 20 guidelines presented in this paper for the design of consistent computer interfaces are based on the data derived from the use of a 94-item, nine-factor questionnaire, the Interface Consistency Testing Questionnaire (ICTQ), that was administered to 140 participants. The questionnaire data was collected from a total of 20 diversified tasks. The questionnaire on which the guidelines are based has a good construct validity, interrater reliability (0.75), and internal consistency as measured by Cronbach's a (0.81). The questionnaire proved to be adequately sensitive to discriminate between consistent and inconsistent interface designs.
