The helping older people engage (HOPE) study: Protocol & COVID modifications for a randomized trial*

Objectives: Evidence-based strategies to reduce loneliness in later life are needed because loneliness impacts all domains of health, functioning, and quality of life. Volunteering is a promising strategy, as a large literature of observational studies documents associations between volunteering and better health and well-being. However, relatively few studies have used randomized controlled trials (RCTs) to examine benefits of volunteering, and none have examined loneliness. The primary objective of the Helping Older People Engage (HOPE) study is to examine the social-emotional benefits of a social volunteering program for lonely older adults. This manuscript describes the rationale and design of the trial.Methods: We are randomly assigning adults aged 60 or older (up to 300) who report loneliness to 12 months of either AmeriCorps Seniors volunteering program or an active control (self-guided life review). Co-primary outcomes are assessed via self-report-loneliness (UCLA Loneliness Scale) and quality of life (WHOQOL-Bref). Enrollment was completed in May 2022 and follow-up assessments will continue through May 2023, with completion of primary outcomes soon thereafter.Conclusions: Since older adults who report loneliness are less likely to actively seek out volunteering opportunities, if results support efficacy of volunteering for reducing loneliness, dissemination and scaling up efforts may involve connecting primary care patients who are lonely with AmeriCorps Seniors through aging services agencies. This RCT is registered at clinicaltrials.gov (NCT03343483).

Automated summary

The HOPE study aims to examine the social-emotional benefits of a social volunteering program for lonely older adults. The study randomly assigns adults aged 60 or older who report loneliness to participate in either the AmeriCorps Seniors volunteering program or a self-guided life review. The outcomes, including loneliness and quality of life, will be assessed through self-report measures. The study's findings may inform the dissemination and scaling up of volunteering efforts for reducing loneliness among primary care patients.
