- Group II (psychoeducation, paced respiration, and relaxation [PEPRR]): Caregivers and patients attend a 2-hour orientation class identical to group I. Caregivers also participate in the PEPRR intervention comprising an individualized stress management component and educational component that addresses the psychosocial needs of the caregivers. It also provides self-care and adaptive coping skills. The stress management component addresses caregivers' perception of potential stressors (primary appraisal); perceived ability to control or manage the stressor (secondary appraisal); ability to exert control and cope with the stressor (coping effort); and ongoing evaluation of the stressor and their perceived ability of managing the stressor (reappraisal) and applies coping strategies such as relaxation, prioritizing, goal setting, pacing, and communicating needs. The PEPRR intervention consists of 8 sessions (4 weekly 60-minute sessions followed by 4 biweekly 60-minute sessions) that cover the 100-day period of caregiving post-transplantation. Caregivers also undergo paced respiratory (RESPeRATE™) training for 15 minutes once daily over 12 weeks that measures caregiver adherence and compliance to the relaxation program.
