Longitudinal data • longitudinal surveys involve repeated surveys of the same individuals at different points in time • allow researchers to analyse change at the individual level • more complex to analyse

Secondary analysis potential • descriptive material • comparative research, restudy or follow-up study • re-analysis/secondary analysis • research design and methodological advancement • replication of published statistics • teaching and learning
Secondary analysis potential • description • comparative research, restudy or follow-up study • augment data you collect e.g. expand sample size • re-analysis or secondary analysis • verification • research design and methodological advancement • teaching and learning
Re-using qualitative data • Archived qualitative data are a rich and unique, yet too often unexploited, source of research material. • They offer information that can be re-analysed, reworked, and compared with contemporary data. • In time, too, archived research materials can prove to be a significant part of our cultural heritage and become resources for historical as well as contemporary research. • What then are the methodological, ethical and theoretical considerations relating to the secondary analysis of qualitative data?
Culture of re-use • well-established tradition in social science of reanalysing quantitative data • no logical intellectual reason why this should not be so for qualitative data • however, among qualitative researchers no similar research culture • lack of discussion of the issues involved in literature on the benefits and limitations of such approaches • more now published, but more needed …!
Data and Methods • often a diversity of methods and tools rather than a single one are encompassed • types of data collected vary with the aims of the study and the nature of the sample • samples are most often small, but may rise to 500 or more informants • as we have seen data include interviews, group discussions, fieldwork diaries and observation notes, personal documents, photographs etc. • created in a variety of formats: digital, paper (typed and hand-written), audio, video and photographic
Description • describing the contemporary and historical attributes, attitudes and behaviour of individuals, societies, groups or organisations • data created now, will in time become a unique historical resource • providing alternative sources (the people’s voice etc.) to the public record that will be deposited in archives
Comparative research, replication or restudy • of original research • to compare with other data sources • to provide comparison over time or between social groups or regions etc. • to follow up original sample • verification - substantiating results, although we have yet to see any evidence of re-use for this purpose (might be useful in a teaching context though)
Re-analysis • secondary analysis • asking new questions of the data and making different interpretations to the original researcher • approaching the data in ways that weren't originally addressed, such as using data for investigating different themes or topics of study • the more in-depth the material, the more possible this becomes
