The case study deals with the processes that take place and their interrelationship. These elements delineate case study from other forms of research and inform the critical aspects of the research design and execution. What are case studies used for? Outcomes from individual case studies are not statistically generalisable but analytically generalisable Welsh and Lyons 2001. Our aim in writing this piece is to provide insights into when to consider employing this approach and an overview of key methodological considerations in relation to the design, planning, analysis, interpretation and reporting of case studies. Our thanks are also due to Dr.
Adherence to the manualised treatment for depression appears good to excellent. Data Resource: Are sufficient data sources identified? Yin has assisted numerous other research groups, helping to train their field teams or to design research studies. Introduction: The discipline and practice of qualitative research. Researchers may choose to use one of these methods to collect data single method approach or they may use several methods multi-modal approach. Such judgements will inevitably be influenced by a range of factors, including the research question, theory of interest, the scope and richness of the gathered data and the resources available to the research team. Her research interests are primary health care, public health and health systems strengthening.
Case study sites may also be pre-selected for the researcher, with decisions being influenced by key stakeholders. In case the same is not true, then consequences follow. However, this might be different from one context to another. Case data are quite useful for diagnosis, therapy and other practical case problems. The method selected depends upon the nature of the question being asked and the goals of the researcher.
Examples of misalignment in experimental and correlational contexts are given and their consequences discussed. In its absence, generalised social science may get handicapped. Pursuing this same example, when does the process of implementation and adoption of an electronic health record system really begin or end? Whilst such a schema can be conceptually helpful, it may be appropriate to draw on more than one approach in any case study, particularly in the context of conducting health services research. This usually involves searching the data to identify and categorize specific actions or characteristics. However, if the primary research interest had been on the social and organisational dimensions of implementation, we might have defined our case differently as a grouping of healthcare professionals e. Case study methods in the international relations subfield.
Qualitative inquiry and research design: Choosing among five approaches. At one recruited site, it quickly became apparent that access was problematic because of competing demands on that organisation. Case Study Method This module describes the case study method of descriptive research and its uses. The authors reported how this case study approach provided a number of contextual factors likely to influence the effectiveness of the intervention and which were not likely to have been obtained from quantitative methods alone. With the capacity to tailor approaches, case study designs can address a wide range of questions that ask why, what, and how of an issue and assist researchers to explore, explain, describe, evaluate, and theorize about complex issues in context.
Case study findings can have implications both for theory development and theory testing. This type of study is a prelude to the design and implementation of a large-scale research investigation. The integration of formal, statistical, and narrative methods in a single study, combined with the use of empirical methods for case selection and causal inference, demonstrated the versatility of case study design and made a significant contribution to its methodological evolution ibid. These methods may include interviews, field studies, protocol or transcript analyses, direct participant observations, a review of documents and archived records, and an exploration of artifacts. Providing a complete portal to the world of case study research, the Fourth Edition of Robert K.
In fact, it may be considered the gateway to and at the same time the final destination of abstract knowledge. This distinction accentuates the need for researchers to describe the particular underpinning methodology adopted and to clarify the alignment of chosen methods used with their philosophical assumptions and their chosen approach. In another example of an intrinsic case study, Hellstrom et al. Proceedings of the European Conference on Information Systems. Descriptive case aim essentially to document or classify a situation. This multi-designs approach is indent to provide a more holistic view of the dynamics of the research subject.
There are several types of case study methods. The research methodology case study may be somewhat controversial as far as data collection methods are concerned but are widely used if your research concerns an in-depth explanation of social behavior which makes case studies methodology a perfect technique for social science students. This thoroughly revised text now covers more than 50 case studies approximately 25% new , gives fresh attention to quantitative analyses, discusses more fully the use of mixed methods research designs, and includes new methodological insights. Clarifying case study research: Examples from practice. It is important that data sources from different cases are, where possible, broadly comparable for this purpose even though they may vary in nature and depth. Comparative Political Studies, 40 2 , 196-214. Collective alignment of these elements articulates a justifiable framework for the research study and cultivates trustworthiness and the validity, reliability and credibility of the research findings.
