"Evaluation in a Nutshell" is a succinct guide to the key elements to evaluating public health interventions. It adopts a similar approach to the successful "Theory in a Nutshell". The book presents an overview of different purposes and types of research to aid health promotion planning, and also makes connections to evidence-based practice and theories of accountability. It is a practical guide to different research designs and evaluation methods, and is useful for both public health students and practitioners.
