Investigating Abnormal Behaviour E. Miller and S. Morley, London: Weidenfeld and Nicolson 1986, pp. 336, £9.95.

In this book the authors aim to provide an analysis of the key issues that arise in the classification, investigation and treatment of abnormal behaviour. Rather than attempting to cover the whole range of phenomena that come under this heading they focus on several examples, these being areas with which the authors are well acquainted. The book begins with a chapter examining general issues of description, classification and investigation in abnormal psychology. Several chapters are then spent on depression. This topic is examined in some considerable detail and includes sections on the epidemiology, genetics and biochemistry of depression, in addition to discussion of the various psychological models, including behavioural, cognitive and psychodynamic approaches, the latter being dealt with in less detail. Treatment strategies are then considered with emphasis given to the links between these and the theoretical models. Schizophrenia is also discussed briefly, with emphasis given to the recent research on environmental influences on the course of schizophrenia, and this is used as an illustration of the importance of interactional influences on some disorders. The subject of headaches is also examined, as an example of a psychological approach to a "medical" disorder. The account is rather short but is well-written and gives an up-to-date introduction to the area. The final area of pathology covered is mental handicap, with a short chapter on psychological approaches to the learning difficulties encountered by such individuals. This chapter, however, is too short to do justice to the range of work currently being done by psychologists in this field, both experimentally and clinically.
