Official title: Project HOPEFUL (Helping Older PErsons Find Useful Links): Replicating a Partially Nested Randomized Control Trial With Implementation Science

Run by University of Florida · NCT07475039 · Data updated 2026-11-12

This project tests whether 8 weeks of friendly 20–30 minute phone calls from trained helpers can reduce loneliness, suicidal thoughts, and improve social connection and quality of life for homebound older adults who receive aging services.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults age 65 or older who are homebound and receiving Home and Community-Based Services through partnered Aging Services Network organizations and who can provide verbal informed consent and comply with study procedures.

Probably not a fit

People who are under 65, not receiving services from a partnered aging agency, unable to consent or engage in phone calls, or those needing immediate psychiatric crisis care are unlikely to benefit from this program.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This partially nested randomized trial assigns homebound older adults receiving Home and Community-Based Services to one of two 8-week warm-calling interventions or to a no-contact control with the option to receive the program after eight weeks. Callers deliver manualized, empathic 'Belongingness and Empathy' (BE) content alone or BE plus a standardized suicide intervention training (ASIST), with calls delivered in 20–30 minute doses. Outcomes include measures of mental health, social functioning, quality of life, and coded provider behaviors from audio recordings, and implementation outcomes such as acceptability, feasibility, and sustainability are measured across multiple levels. Participants are followed with repeated measurements, including longer-term follow-ups to examine sustained effects and connecting behaviors.

Why it matters

Potential benefit: If successful, the intervention could reduce loneliness and suicidal ideation while improving social support and quality of life for homebound older adults.

How similar studies have gone: Related 'caring contacts' and befriending interventions have shown promise for reducing loneliness and suicidal thoughts in older adults, but randomized replications within real-world aging service networks remain limited.
