Effects of 'participatory group-based care management' on wellbeing of older people living alone: a randomized controlled trial.

Background And Objectives: More knowledge is needed of the effectiveness of complex interventions that aim to promote the wellbeing of older people. This study examines the effects of 'participatory group-based care management' conducted among community-dwelling older adults living alone in Central and Eastern Finland. The intervention aimed to promote wellbeing and quality of life (QoL) using a needs-based and participatory approach.

Methods: The study was carried out as a randomized control trial (intervention group n = 185, control group n = 207). In this article, baseline and 6-month follow-up surveys were used. QoL (WHOQOL-Bref instrument), loneliness (Revised UCLA Loneliness Scale; single-item question), and trust (two items of generalized trust and six items of institutional trust) were used as outcome measurements, and generalized estimating equations (GEE) modeling as the analysis method. Both per-protocol and intention-to-treat analyses were applied.

Results: According to the per-protocol analysis, the intervention had no effects on QoL. Loneliness decreased among older people with poor QoL at the baseline. Additionally, the intervention enhanced trust in other people and some dimensions of institutional trust. The intention-to-treat analysis did not result in any significant effects on QoL or loneliness, but some small positive changes in institutional trust were found.

Conclusions: Based on some evidence of small positive effects, the intervention may be beneficial in alleviating loneliness and enhancing trust among older people living alone. Because of the contradictory results, more research is needed to examine the complexity of 'participatory group-based care management´ from the perspective of process evaluation.
