Overview

Background Social isolation and loneliness (SIL) worsens mortality and other outcomes among older adults as much as smoking. We previously tested the impact of the HOW R U? intervention using peer support from similar-aged volunteers and demonstrated reduced SIL among older adults discharged from the emergency department (ED). Generativity, defined as “the interest in establishing and guiding the next generation,” can provide an alternative theoretical basis for reducing SIL via intergenerational programs between members of younger and older generations. The current protocol will examine the impact of younger intergenerational volunteers providing the HOW RU? intervention. Methods In this randomized clinical trial, we will compare the following three arms: (1) the standard same-generation peer support HOW R U? intervention, (2) HOW R U? intervention delivered by intergenerational volunteers, and (3) a common wait-list control group. Outcome assessors will be blinded to the intervention. Trained volunteers will deliver 12 weekly telephone support calls. We will recruit participants ≥ 70 years of age with baseline loneliness (six-item De Jong loneliness score of 2 or greater) from two EDs. Research staff will assess SIL, depression, quality of life, functional status, generativity, and perceived benefit at baseline, at 12 weeks, and 24 weeks post-intervention. Discussion We hypothesize participants receiving the intergenerational intervention will show improved outcomes compared to the control group and peer support HOW R U? intervention. We also hypothesize that participants with higher perceptions of generativity will have greater reductions in SIL than their lower generativity counterparts. Aging is experienced diversely, and social interventions combatting associated SIL should reflect that diversity. As part of a program of research following the Obesity-Related Behavioral Intervention Trials (ORBIT) model, the findings of this RCT will be used to define which intervention characteristics are most effective in reducing SIL.
