Applying the PDSA cycle to a group activity promoting lifestyle change for the active ageing of older Thai adults – a focused ethnography

BACKGROUND: The proportion of the older Thai population is increasing rapidly. Lifestyle may impact active ageing in later life. Interventions that empower older Thai adults to initiate and carry out lifestyle changes are needed. This study applied the Plan-Do-Study-Act (PDSA) cycle, a tool for improving lifestyle changes, with the aim of exploring interactions among older Thai adults when participating in group activities. METHOD: Focused ethnography was used based on participant observations, field notes and video recordings of 15 older Thai adults aged 62–78 years. RESULTS: Older Thai adults faced difficulties at the beginning since they were unfamiliar with initiating and carrying out lifestyle changes according to the PDSA concept. This provided a learning opportunity enabling older Thai adults to reach their individual goals of lifestyle change. CONCLUSIONS: The PDSA cycle has the potential to empower older adults in group contexts to promote lifestyle changes related to active ageing.
