We are delighted to share with you a new GOLTC Methods Guide on Propensity Score Matching (PSM).

The GOLTC Methods Guides are short introductions to useful methods for Long-Term Care research written by researchers who use these methods and want to share their experience and knowledge.

The Propensity Score Matching guide has been written by Joaquin Mayorga and Javiera Cartagena-Farias (London School of Economics and Political Science).

Propensity Score Matching (PSM) is a quasi-experimental method that creates a control group by matching “treated” units (i.e., those participating in a programme or intervention) with non-treated units of similar observable characteristics before the intervention took place and is increasingly used in observational studies where it is not possible to randomise.

You can read the more about this method and how to use it here.
