This paper considers the advantages and limitations of using mixed methods, diaries and focus groups in research with older people, specifically research investigating the interaction experiences of older individuals as customers, members and workers with public-, private- and community-based organisations. Drawing on the literature on mixed method integration, five distinct advantages were identified: development, completeness, expansion, offsetting and initiation. Two limitations were also noted: demands of the data collection on the participants and insufficient depth. Each is discussed in the context of the particular research project, with the suggestion that mixed methods be used in future research with older people.
