Twenty-eight participants (88 percent) from the support group and 31 (94 percent) from the psychoeducation group completed the intervention. These participants, together with those who dropped out or were absent for more than four group sessions—five in the mutual support group (16 percent), two in the psychoeducation group (6 percent), and one in the standard care group (3 percent)—were evaluated at three outcome measurement points (Figure 1). Reasons for discontinuing treatment were similar for the two interventions, including insufficient time to attend (three participants, or 5 percent), worsening of the patient's mental state (three participants, or 5 percent), the caregiver's being the only person taking care of the patient (two participants, or 3 percent), and lack of interest (two participants, or 3 percent).
