Evaluating a Multimodal Intervention for Hong Kong's Older Informal and Precarious Workers

Purpose: This article evaluates the Pickers’ Link, a Hong Kong initiative enhancing older waste pickers’ bio-psycho-social well-being, addressing research and practice gaps for precarious workers. Methods: The study employed a mixed-methods approach, using qualitative analysis to assess program influences in 30 participants, and quantitative measures to evaluate changes in pain, cognition, and physical performance in 28 participants pre- and post-treatment. Results: The program's influence and mechanisms were captured in themes spanning social and digital engagement, health and mobility benefits, crucial outreach engagement and personalized support. The quantitative analysis revealed pain reduction and cognitive enhancements post-treatment, while improvements in grip strength and physical function did not meet clinical significance thresholds. Discussion: Practice for older informal and precarious workers should prioritize outreach, bio-psycho-social health, diverse interactions, and flexible programming. This study presents an innovative approach to evaluating community initiatives and underscores the value of interdisciplinary efforts in social work practice and research.
