Quasi-experimental studies evaluate the association between an intervention and an outcome, using experiments in which the intervention is not randomly assigned.

Born in Bradford has a growing number of researchers with experience and interest in the use of quasi-experimental methods (QEM). The QEM group is an opportunity for those interested to discuss and learn about different types of quasi-experimental study designs and their key methodological considerations, hear examples of previously-conducted studies and experiences using QEM, and think about opportunities for the use of QEM using data collected from the BIB cohort.
The QEM group meetings are held monthly with a hybrid in-person and online format. Recordings of the monthly talks, as well as links to presentation slides, relevant studies and other useful resources can be accessed below.
