This use of SCEDs is perhaps the most similar in intent to the traditional case study, which often seeks to document unusual cases, but once again, differs because of the inclusion of systematic measurement and control. (1990) utilizing Rohatgi’s WebPlotDigitizer software. Please enable it to take advantage of the complete set of features! For example, statistical analysis may have shown that birthrates in African countries are increasing. Orand A, Erdal Aksoy E, Miyasaka H, Weeks Levy C, Zhang X, Menon C. Sensors (Basel). Secondly, single case study can be used to explain a unique or extreme case. They can be designed to have strong internal validity for assessing causal relationships between interventions and outcomes, as well as external validity for generalizability of results, particularly when the study designs incorporate … A case study is a detailed study of a specific subject, such as a person, group, place, event, organization, or phenomenon. We observe patient problems and respond. ▪ How are single-case experiments designed? From the above, it should be immediately apparent that the SCED is a quantitative approach to research. Yet there are several important components that cannot be skipped because they establish the valuable core and supporting … As we can see from, Tempting as it is to infer improvement from the graph in, In the above example, the patient’s improvement has not been maintained following return to, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), Click to share on Google+ (Opens in new window). Data were extracted from Hinderer at al. Evaluation of the Effectiveness of a Novel Brain-Computer Interface Neuromodulative Intervention to Relieve Neuropathic Pain Following Spinal Cord Injury: Protocol for a Single-Case Experimental Design With Multiple Baselines. Just as different group experimental designs seek to reduce different sources of bias, so do different single-case experimental designs. In the social and life sciences, a case study is a research method involving an up-close, in-depth, and detailed examination of a particular case. Data were extracted from Mechling at al. Generally, a case can be nearly … Single-case studies can be designed and analyzed in a rigorous manner that allows researchers strength in assessing causal relationships among interventions and outcomes, and in generalizing their results. of our interventions with patients, using a credible research approach, during our everyday clinical practice (, The SCED may also be an extension of this clinical use, where we can use experimental control to build up a systematic picture of a patient’s characteristics or difficulties. 2, 12 These studies can be strengthened via incorporating replication of findings across multiple study phases, participants, … An analysis of current trends in single case design, based on publications in two leading behavioural journals, highlights a move toward alternating treatment designs and the growth of cognitive measures in single case studies. Making the switch: From case studies to N-of-1 trials. This idea was borrowed from natural sciences, principally by behaviourists in the 1940s and 1950s who sought to identify governing principles or laws of human behaviour which were similar in applicability to laws in the natural sciences, which govern such issues as the diffusion of gases or the rate of cooling of a liquid. Finally, it should not be ignored that a signal … The Single Case Archive compiles clinical, systematic, and experimental single case studies in the field of psychotherapy. From the above, it should be immediately apparent that the SCED is a quantitative approach to research. From various epistemological and analytical standpoints, single case study analysis can incorporate both idiographic sui generis cases and, where the potential for generalisation may exist, nomothetic case studies suitable for the testing and building of causal hypotheses. Note that although a stable baseline is recommended for SC studies, it is not always possible to satisfy this requirement, as you will see in Figures 1–4. Themes arise from the analyses and assertions about the cases as a whole, or the quintain, emerge.6 Benefits and limitations of case studies If a researcher wants to study a specific phenomenon arising from a particular entity, then a single-case study For the remainder of this chapter, we will use the treatment of a person with multiple sclerosis as a case example. A case study research design usually involves qualitative methods, but quantitative methods are … The researcher using single-case experimental methods applies the same ideas about control of variability as in traditional group experiments, attempting to control for bias which results both from subjects and from design. 19.3). Single-case studies can provide a viable alternative to large group studies such as randomized clinical trials. When a single case study is used, the researcher can question old theoretical relationships and explore new ones because of that a more careful study is made. Researchers describe how case studies examine complex phenomena in the natural setting to increase understanding of them.3 4 Indeed, Sandelowski5 suggests using case studies in research means that the holistic nature of nursing care can be addressed.
