Aimed primarily at psychiatric trainees sitting the MRCPsych part II, this text should also appeal to more senior and junior psyhiatrists, other mental health professionals and managers who need a brief but comprehensive introduction to the underlying concepts and practice of evidence-based mental health (EBMH). It covers the principal components of research methods, relevant statistics and critical appraisal processes for doctors and particularly psychiatrists. An everyday clinical relevance is maintained throughout with examples from psychiatric literature where possible.
