Purpose: This study examined the effects of the professional support group on self-efficacy and burden of the family members with a schizophrenic patient. Method: This study used a non-equivalent control group pre-post design. The data was collected from April, 2002 to December, 2002. The subjects consisted of 21 family members. The experimental group(n=11) participated in a support group that consisted of 3 sessions(3-week period); the control group(n=10) did not participate in. To examine the effects of the professional support group, self-efficacy and burden of the family were measured before and after the program. Result: In the experimental group, there was no significant change in self-efficacy after the program (Z=-.059, p=.953). The scores of burden increased after the program but did not significantly change (Z=-1.572, p=.116). In the control group, there was no significant change on self-efficacy after the intervention period (Z=-.339, p=.735). The scores of burden increased after the program but did not significantly change (Z=-.722, p=.440). Conclusion: Although the professional intervention that aims to increase self-efficacy and decrease burden for family with mentally ill relatives is important.
