The theoretical model of person-environment-occupation (PEO) fit (1), provides a transactional view of the interplay between such issues as the health of an individual, home environment and occupational pursuits. Over a lifespan the balance between these elements shifts, so that environmental and occupational changes may occur in response to declining health. In very old age it becomes increasingly important to understand the interactive relationship between these issues. Little however is known about the daily lives of very old people living at home, about how their health or well-being is affected by their home environments (2), or about ways to meet occupational needs when health may be poor and the home no longer “user-friendly”. The international, interdisciplinary Enable-Age project team, is well placed to address such deficiencies. It uses a multi-methods approach, to explore the complex relationship between home, health and occupation, and locates the findings within international policy directives. This paper demonstrates how integrated methodologies are addressing three major questions: (1) Is there a relationship between the home environment, personal health and occupation amongst very old people? Survey results are highlighted from approximately 400 people per country, all aged between 75 and 89 years. (2) What role does occupation at home play in the everyday lives of older people? Initial findings from 120 (40 per country) in-depth semi-structured interviews, point to the important role of home-based activity in later life. (3) How might policy initiatives support home-related occupations amongst older people? Case examples from UK, Latvia and Sweden will be used to illustrate the early project findings, and locate these within the theoretical framework of the PEO model.
