Analysing Qualitative Longitudinal Research in Evaluations

Abstract

This article describes the processes and objectives of qualitative longitudinal analysis in evaluation research, using a recent evaluation study – the evaluation of the Job Retention and Rehabilitation Pilot – as an example. It describes evaluation research as involving an interplay between four domains of change: individual, service, policy and structural, which makes longitudinal qualitative research a particularly rich data source. It outlines different types of change that may be evident: narrative change, reinterpretation by either participant or researcher, and the absence of change. The article describes how the Framework analysis method was used to analyse longitudinal qualitative research. It examines how the data can be read in different ways to combine cross-sectional and longitudinal analysis, and theme, case and group analysis, and discusses the kind of questions that can be asked of change in longitudinal qualitative evaluation studies.
