The single-case design is not only used in controlled clinical research. It is also informally applied by the physicians we see every day. Are there strengths and weaknesses here?

The question you are posing appears to reflect an interest in single case design and whether or not the use of this design is credible. Kratochwill and Levin (2010) discuss the use of single case design research as working much like other research in that the researchers are looking to identify a causal relationship between an intervention and a change in the baseline behavior as a result of that intervention. This design can also identify different interventions and compare those with the baseline behavior to determine which has a causal effect the researcher is looking for. Kratochwill and Levin (2010) discuss the use of a "within-series" design that measures participant performance during different conditions within the experiment, such as different interventions. The use of more than one subject or replicating the study using the same design provides a better basis for validity. One of the key strengths of this design is the ability to introduce specific interventions and measure outcomes.

One of the key components to consider when addressing the question posed is to consider what the researcher or ...
