During 1990, 83 patients seen for a general physical examination at a family practice clinic completed a computer-based health risk appraisal in one of two formats, batch or interactive. They also completed a written questionnaire on their health risks and knowledge before taking the appraisal, and 65 of them completed another health risk appraisal and questionnaire three months later. No difference in user evaluation of the appraisal regarding its helpfulness, their intent to change behavior based on the appraisal, or amount learned from the appraisal was found between batch and interactive formats. About half (48%) of the individuals correctly estimated their overall health risks before taking the health risk appraisal. Among those who initially misjudged their health risks, few women adjusted their health risk rating at followup. Men showed a tendency to adjust their rating to more closely agree with the health risk appraisal estimates although the differences are not statistically significant. Eighty percent of the men and 55% of the women accurately rated their overall risk at followup. Knowledge of specific causes of death did not improve at followup.
