Role of the Designee: Following informed consent, the designated family member or friend (hereafter called designee) continued through the study with the patient as a 'unit'. The designee attended the patient's educational sessions during stages 3 and 4, with stage 2 being according to the family member preference. Recall that stage 2 deals with patient expectations, stage 3 with patient acceptance and problem-solving, and stage 4 with evaluations and internalizing his/her locus of control. The designee and the patient attended the same sessions, and studied the same learning materials. Up to eight family members were allowed to join in the educational sessions if requested. In stage 3, the designee was charged with learning and reinforcing educational material with the patient. In stage 4, when instructed by study investigators, the designee would administer the KAP assessments to the patient. In addition to scores, the designee would provide additional information on the patient's home situation and current condition. Patients were assigned a code, and de-identified data were transmitted from the designee to investigators either by encrypted email, telephone, mail or in person.
