Learning to PERSEVERE: Peer Mentor Support and Caregiver Education in Lewy Body Dementia

Scientific Premise. PERSEVERE is a theory-based intervention that applies Social Cognitive Theory constructs to the revised Stress Process Model to improve caregiving mastery and ultimately, outcomes. PERSEVERE targets education about common causes of hospitalization in LBD patients combined with social support from trained peer mentors to enhance caregivers' mastery and LBD knowledge. Social Cognitive Theory (SCT) proposes that behavior change is dynamic, affected by expectations, observational learning, and reciprocal influences from the environment.

Study procedures. Aim 1 (Fall 2020): Revise the mentor training curriculum, conversation guides, and resource handbook. The team will convene focus groups of previously trained mentors, LBD caregivers, and LBD professionals, present each group with the original mentor curriculum (training presentation slides and handbook) and the proposed educational resources for inclusion in the revised curriculum and obtain their feedback. Framework analysis will be used to guide the revision of the mentoring curriculum, with provision of practical checklists, goal setting, and step-by-step guides for key areas of LBD caregiving mastery in addition to social support, structured as the 16-week PERSEVERE curriculum.

Aim 2 (Winter 2021): Recruit and screen 36 peer mentors as PERSEVERE is being revised, followed by two 6-7 hour training sessions for mentors in early 2021. Each selected mentor will attend one training session, where the following content will be delivered: 1) study logistics, expectations, and informed consent; 2) baseline mentor data collection; 3) active listening, mentoring, goal- and boundary-setting; 4) overview of LBD, risk factors for hospitalization, impact on caregiver; and 5) practical approaches to symptom management and caregiving issues. The week-by-week PERSEVERE curriculum will be presented along with the accompanying handbook. The investigators will solicit questions and role-play conversations. The study team will encourage mentors to direct their mentees to call their respective medical teams with specific medical questions, however the study team will inform the mentors that they may contact the study team directly for non-emergent advice and resources. Mentors will complete post-training assessments and will receive a training stipend. Mentors' caregiver mastery will be assessed using Pearlin and Schooler's scale pre- and post-training.

Aim 3 (Spring-Summer 2021): Recruit 30 LBD caregivers and conduct baseline assessments including demographics, relationship to LBD patient, and duration of caregiving. Mentors will be matched to caregivers by relationship to LBD patient, then by sex and age, as much as possible. Mentor-mentee pairs will be formed and the PERSEVERE handbook and contact information will be distributed. Pairs will be expected to speak for >15-30 minutes weekly, and to review that week's PERSEVERE topics in the handbook before or during each call to facilitate meaningful conversations. Discussions are not scripted and will not necessarily be limited to that week's topics. Mentors and mentees will complete online study diaries every 2 weeks, assessing intervention fidelity. Up to 3 reminders will be sent to complete each study diary, and if missing, a team member will call the participant(s). Mentors will participate in a total of 4 recorded monthly conferences with the study team. Mentees' caregiver mastery, strain, anxiety, and depression will be assessed at baseline and after the 16-week program. Feasibility will be assessed via online surveys and study team phone call follow-up.

This pilot study will determine the necessary qualities of mentors and matching, the content of the mentor training and PERSEVERE handbook, and the effect sizes of the intervention to determine the sample size for a forthcoming R01.
