Quasi-Experimental Designs for Causal Inference

A tutorial on Quasi-experimental designs

A main step in answering a scientific hypothesis in an epidemiological study is deciding which type of study is suitable to be undertaken, considering methodology, practical considerations and budget and time limitations

4 Quasi - experimental Designs

Experimental designs for identifying causal mechanisms

Experimentation is a powerful methodology that enables scientists to empirically establish causal claims. However, one important criticism is that experiments merely provide a black-box view of causality and fail to identify causal mechanisms. Specifically, critics argue that although experiments can identify average causal effects, they cannot explain the process through which such effects com...

Quasi-Experimental designs for quality improvement research

Presentation Quality Improvement (QI) research may be defined as “the design, development and evaluation of complex interventions aimed at the re-design of health care systems to produce improved outcomes”. The challenge of QI lies in bridging the gap between knowing what needs to happen at an individual patient level and implementing this at a systems level. The inherent complexity of systems ...
