It is interesting that the attrition rates in all three groups were very low. The high group attendance rate may be explained by the fact that in this sample the illness was of short duration and the families may thus have been more optimistic and motivated about the potential for change (3,6). Thus there is a need for family services to offer accessible and early intervention when planning patients' discharge. Research on support groups also suggests the importance of understanding the helpful environment within and outside a support group and the need to emphasize the exploration of its therapeutic ingredients (31). However, the difference in attrition and nonattendance between the two interventions (15.6 percent compared with 6.1 percent) favoring the psychoeducation group is worthy of exploration in follow-up study with larger samples
