Health Status of Lewy Body Dementia Caregivers Predicts Psychological Response to Peer Mentoring Intervention.

Individuals with Lewy body dementia (LBD) rely on family caregivers. Caregiving demands limit caregivers' ability to attend to their own health needs, increasing their vulnerability to the psychological effects of caregiving. We previously piloted a peer mentoring intervention with experienced (mentor) and less experienced (mentee) LBD caregivers. Matched mentor-mentee dyads spoke weekly for 16 weeks, guided by an intervention handbook. LBD knowledge and attitudes towards dementia improved post-intervention. We hypothesized that caregiver health status moderates response to peer mentoring. Post hoc analyses (N = 30 dyads) showed that 75% of mentees and 66% of mentors endorsed ≥1 comorbidity. Mentees and mentors with comorbidities showed greater improvement in LBD knowledge postintervention (P = 0.039) and dementia attitudes post-training (P = 0.016), respectively. Caregivers with comorbidities and thus greater exposure to health care may derive excess benefit from an effective LBD caregiver intervention than healthier counterparts, enhancing both the objective knowledge and their confidence in caring for their loved ones.
