   Does involving volunteers in the provision of palliative care make a difference to patient, family, and unpaid carer wellbeing and service use? A systematic review.

   Palliative medicine (Willis et al.)Published Aug 31, 2026Checked Oct 4, 2026

   “Eligible studies included adults with a terminal illness, their family members or unpaid carers participating in volunteering interventions. Critical appraisal was conducted using Joanna Briggs Institute tools.ResultsTwenty-nine reports relating to 24 studies were included. Volunteering roles included peer support, befriending, information provision, arts-based interventions, and practical support. Volunteering interventions positively impacted patients' hedonic wellbeing, quality of life, and mental health. For eudaimonic wellbeing, quantitative data demonstrated mixed results, while qualitative studies suggested improved social connection. For unpaid carers, there was limited quantitative evidence of impact on wellbeing. Qualitative data indicated interventions were beneficial in supporting advocacy and were well received.ConclusionsQualitative data indicated volunteering interventions were well received by patients and unpaid carers. Quantitative studies were limited by small sample sizes but demonstrated positive trends. Little evidence that volunteering was associated with harm.”

   Health benefits and harms of older adult volunteering: mixed methods systematic review.

   The Gerontologist (Williams et al.)Published Apr 1, 2026Checked Oct 4, 2026

   “Data were extracted and categorized according to health outcome. This review was registered on PROSPERO https://www.crd.york.ac.uk/PROSPERO/view/CRD42023456281RO.ResultsThe search yielded 182 papers related to a wide range of health benefits and harms. RCTs were assessed for risk of bias using CASP checklists. There were 11 RCT papers from five trials. Included RCTs had a high risk of bias. Benefits and harms were categorized into biological, psychological, social, and biopsychosocial intersect domains. Papers largely reported on multiple health benefits of volunteering. There were negligible reports of harms compared to benefits.Discussion and implicationsVolunteering is seemingly beneficial to older adults, though more evidence from experimental studies is needed to clarify discrepancies and substantiate current recommendations. Harms may be under-reported. Further clarity may allow for more older adults to participate in volunteering, while maximizing health benefits and avoiding harms. Additionally, further research could inform governments and volunteer organizations on how to implement and advertise programs appropriately.”

   Prosocial helping behaviors attenuate accelerated cognitive decline driven by APOE ε4.

   Alzheimer's & dementia : the journal of the Alzheimer's Association (Han & Faul)Published Sep 1, 2026Checked Oct 4, 2026

   “IntroductionThe apolipoprotein E (APOE) ε4 allele accelerates cognitive decline through multiple biological pathways-including neuroinflammatory, vascular, and stress-regulatory mechanisms-yet few modifiable behaviors counter this genetic vulnerability. Prosocial helping engages these same systems in opposing directions, suggesting it may attenuate APOE ε4-related cognitive decline.MethodsWe analyzed more than two decades of longitudinal data from a large, multiethnic US sample (N = 17,972). Multilevel models that isolate within-person change tested whether transitions in formal volunteering and informal helping moderate APOE ε4-related cognitive decline, while addressing key sources of endogeneity.ResultsAdopting and sustaining formal volunteering attenuated the accelerated cognitive decline typically observed among ε4 carriers, with protective associations evident at modest engagement levels (≤ 4 hours/week). Informal helping was uniquely protective among Hispanic older adults, highlighting the role of cultural context in prosocial engagement.DiscussionProsocial helping may be a feasible, scalable strategy for slowing APOE ε4-driven cognitive decline.”

   Volunteering and resilience in wartime: evidence from two population-based studies in Israel.

   BMC public health (Merkin et al.)Published Aug 10, 2026Checked Oct 4, 2026

   “In Study 1, multivariable linear regression models were utilized to assess the association between psychological exposure to war and resilience, while accounting for potential interaction between psychological exposure to war and volunteering. In Study 2, latent class analysis was used to identify patterns of volunteering based on type, duration and frequency of activities. Multivariable linear regression models then examined associations between volunteering patterns and resilience, followed by a mediation analysis assessing the role of social integration.ResultsA statistically significant interaction emerged in Study 1 indicating that the relationship between psychological war exposure and resilience was weaker when volunteering was higher. Study 2 found that the pattern characterized by high intensity volunteering at logistic distribution centers was significantly associated with higher resilience (β = 0.49, p = 0.001), with social integration mediating 31% of this effect.ConclusionThese findings show a persistent association between substantive communal volunteering and higher resilience that may buffer the negative impact of war exposure.”

   “Volunteering is an optional and freely chosen act of an individual or group giving their time and labor, often for community service. Many volunteers have specialized training in the fields that they work in, such as medicine, education, or emergency rescue. Others provide their services as needed, such as in response to a natural disaster.”
