Digital Peer Support Intervention for Family Caregivers of Individuals With Neuromuscular Disease: Randomized Controlled Trial
BACKGROUND: Neuromuscular diseases (NMD) affect nerves and muscles, resulting in weakness and often profound disability. Family caregivers of individuals with NMD experience significant psychological burden, stress, and reduced well-being. Digital peer support interventions may help to ameliorate these negative impacts. OBJECTIVE: This study evaluated the effect of a 12-week digital peer support intervention compared to usual care on caregiver mastery, competence, stress, burden, anxiety, and depression among family caregivers of individuals with NMD. METHODS: We conducted a parallel-group multicenter randomized controlled superiority trial in Ontario, Canada. Family caregivers of children or adults with NMD were recruited between August 2022 and September 2023 through 7 sites, social media, and national organizations. Participants were randomized 1:1 to a 12-week digital peer support intervention or usual care. The 12-week intervention comprised access to a trained peer mentor, private app-based communication via aTouchAway (Aetonix, Canada), and weekly moderated digital group discussion forums. The primary outcome was caregiver mastery measured using the Pearlin Mastery Scale, adjusted for baseline score. Secondary outcomes included caregiver stress, competence, burden, anxiety, and depression. We calculated adjusted (for baseline score) mean differences using analysis of covariance and generated multivariable linear regression models exploring associations with the intervention and caregiver age, years of caregiving, care recipient medical diagnosis, care recipient ventilation type, adjusting for baseline outcome scores. Intervention fidelity was evaluated through participant engagement metrics. RESULTS: A total of 100 participants were randomized (n=50 intervention and n=50 control). Participants had a mean age of 46.8 (SD 11.6) years, 70% (n=70) were mothers, with a mean length of caregiving of 11.8 (SD 7.6) years. We found no difference in 12-week Pearlin Mastery Scale scores (adjusted mean difference 0.67, 95% CI -1.7 to 3.1). We also found no difference in any of our secondary outcomes. Mentors and participants sent a mean of 21.3 (SD 33.3) and 17.7 (SD 33.0) messages, respectively. Overall, 62% (n=31) of participants and 92% (n=11) of mentors engaged in at least 1 program element for ≥8 of the 12 weeks. CONCLUSIONS: Our 12-week digital peer support program had no effect on caregiver mastery or other caregiving or psychological outcomes among family caregivers of individuals with NMD. This might be partly due to moderate fidelity and variability in participant engagement. Unlike prior caregiver interventions that incorporated structured psychoeducation or self-management training, this intervention evaluated primarily peer support delivered through a digital platform. This study contributes important evidence regarding the feasibility and limitations of scalable digital peer support programs for caregivers of individuals with NMD. These findings highlight the importance of intervention tailoring, participant matching, and sustained engagement. Future research should evaluate longer-duration and more individualized peer support models targeting caregivers earlier in the caregiving trajectory to improve intervention fidelity and ultimately caregiver well-being.

Caregiver experiences of social isolation and loneliness in chronic kidney disease: systematic review of qualitative studies.
OBJECTIVES: This qualitative systematic review aimed to describe the experiences and perspectives of loneliness and social isolation among informal caregivers of people with chronic kidney disease (CKD). METHODS: Terms for caregivers, qualitative research, loneliness and social isolation and CKD were entered into MEDLINE, Embase, CINAHL and PsycINFO and searched from inception to May 2025. Qualitative studies that described social isolation and loneliness among caregivers of people with CKD were included in this review. Study characteristics were extracted into Microsoft Excel. Qualitative data from each study were imported into HyperRESEARCH and analysed using thematic synthesis. RESULTS: We included 19 articles involving 598 caregivers of people with CKD from 28 countries. Four major themes with subthemes were identified: confined by the patient's needs (social withdrawal due to unrelenting demands, separated from communities due to treatment, torn between work and caregiving responsibilities, foregoing social outings with family and friends, restricted by patient's diet, feeling protective against infection risk); limited care assistance exacerbating isolation (inadequate familial support, absence of respite care, lacking accessible guidance from health professionals); disrupting relationships and social roles (sacrificing social needs and identity, family conflicts worsening isolation, withdrawing to avoid stigma and ridicule, grappling with hopelessness, reluctance to share struggles); and coping with support resources (connecting with other families, seeking assistance from support services, finding support through faith). CONCLUSIONS: Caregivers of people with CKD experience restricted social participation and loss of social roles and identity, which can exacerbate feelings of loneliness and social isolation. Support services are needed to prevent and address social isolation and loneliness in CKD caregivers. PROSPERO REGISTRATION NUMBER: CRD420250637194.
