Though psychology as a discipline has grown enormously in popularity in recent years, compulsory courses in research methods and statistics are seldom embarked upon with any great enthusiasm within the undergraduate and postgraduate communities. Many postgraduate and PhD students start their research ill-equipped to design effective experiments and to properly analyse their results. This lack of knowledge also limits their ability to critically assess and evaluate research done by others.This book is a practical guide to carrying out research in health psychology and clinical psychology. It bridges the gap between undergraduate and postgraduate study. As well as describing the various techniques and methods available to students, it provides them with a proper understanding of what a specific technique does - going beyond the introductory descriptions typical of most undergraduate methods books. The book describes both quantitative and qualitativeve approaches to data collection, providing valuable advice on methods ranging from psychometric testing to discourse analysis. For both undergraduate and postgraduate students, the book will be essential in making them aware of the full range of techniques available, helping them to design scientifically rigorous experiments, and effectively analyse their results.
