THE AMOUNT OF SMALL-GROUP CASE-STUDY DISCUSSION NEEDED TO IMPROVE MORAL REASONING SKILLS OF MEDICAL-STUDENTS

Purpose. To examine how much exposure to small-group case-study discus sion is necessary to significantly increase moral reasoning skills. Me thod. For the classes of 1991-1998 at Texas A&M, using Rest's Defining Issues Test, the authors tested groups of students for moral reasonin g skills both before and after the students participated in small-grou p case study discussions of medical ethics. Results. From 960 students asked to participate, the authors collected complete data for 729 stu dents (75.9% response rate). Small-group case-study exposures ranged f rom 0 to 44 hours. Groups of students exposed to 20 hours or more demo nstrated a significant increase in their moral reasoning scores. Group s with less than 20 hours of exposure demonstrated no significant incr ease in their scores. Conclusion. This study indicates that moral reas oning skills are teachable and measurable, and that small group discus sion significantly increases moral reasoning skills. Further studies a re needed to increase the generalizability of these findings.
