This paper draws on the work conducted on I’DGO (Inclusive Design for Getting Outdoors) examining older people’s perception and preference for neighbourhood outdoor spaces. It comments on the increasing interest in using an ecologically oriented approach to research and theory in environment-behaviour studies. I’DGO addresses positive approaches to ageing, examining older people’s behaviour in relation to different ecological units. In this paper, we stress that a contextualized understanding of older people’s outdoor activities near to their home environment necessarily requires a combination of research methods and we present research findings to demonstrate how these methods can be effectively combined in the same study. A questionnaire was used to examine perceptions in relation to different scales of outdoor spaces close to home, including nearby natural environments, local streets, and local neighbourhood. Open-ended questions and in-depth interviews were used to explore particular places older people visit, their motives for visiting them and the importance attributed to them in the context of their lives. Finally, we illustrate the use of choice-based conjoint analysis, where trade-offs between competing environmental attributes can be estimated. This paper shows how quantitative and qualitative tools help address different aspects of people’s experiences and different scales of their environments. It further discusses the theoretical and practical implications of favoring a multi-method approach and a transactional understanding of person-environment relations.
