Abstract

Background: Older people are at risk for health decline
and loss of independence. Lifestyle interventions offer
potential for reducing such negative outcomes. The aim of this study was to determine the effectiveness and cost-effectiveness of a preventive lifestyle-based occupational therapy intervention, administered in a variety of community-based sites, in improving mental and physical well-being and cognitive functioning in ethnically diverse older people.

Methods: A randomised controlled trial was conducted comparing an occupational therapy intervention and a no-treatment control condition over a 6-month experimental phase. Participants included 460 men and women aged 60-95 years (mean age 74.96±7.7 years; 53% <$12 000 annual income) recruited from 21 sites in the greater Los Angeles metropolitan area.

Results: Intervention participants, relative to untreated
controls, showed more favourable change scores on indices of bodily pain, vitality, social functioning, mental health, composite mental functioning, life satisfaction
and depressive symptomatology (ps<0.05). The intervention group had a significantly greater increment in quality-adjusted life years (p<0.02), which was achieved cost-effectively (US $41 218/UK £24 868 per unit). No intervention effect was found for cognitive functioning outcome measures.

Conclusions: A lifestyle-oriented occupational therapy
intervention has beneficial effects for ethnically diverse
older people recruited from a wide array of community settings. Because the intervention is cost-effective and is
applicable on a wide-scale basis, it has the potential to
help reduce health decline and promote well-being in older people.
