Although informal assessments of caregiver training and support groups have been positive, empirical evidence of their beneficial impact is needed. To evaluate a group program for families of elderly parents, a pre/postmeasure, experimental/control group design was implemented. Adults participating in two workshops on "Your Aging Parents" were assigned to either an experimental (N=16) or a control (N=16) group. All participants completed pre-test measures, including goal statements and 20 items from the 29-item Burden Interview (Zarit, et al., 1980). Post-test questionnaires on the workshop's effectiveness were administered to the experimental group at the end of a 10-hour workshop; at the start of their workshop control group members again completed the Burden Interview. Analysis of results showed that significant differences between groups were found on only three items of the Burden Interview; experimental subjects changed in a positive direction in their feelings of usefulness and contribution, and in feelings about parents' manipulation. Program completers showed no significant change for total burden score. However, participants' ratings of program value and quality were high, and most felt they had achieved their main goals. To empirically evaluate program effectiveness, future research must focus more specifically on the development and administration of a valid and reliable instrument to measure change without disrupting the group process.
