Classification and
Diagnosis of Psychological
Abnormality
How is psychological abnormality recognised? How many different
mental disorders are there, and what are their characteristics? Although
there are established guidelines for clinicians working in this area, these
have been subject to many criticisms. Exploring how views on this
subject have changed over time, and how they vary in different
societies, poses important questions about our current practices.
This book provides a brief overview of the current definitions and
various explanations for psychological abnormality and then focuses
on how society diagnoses and classifies behaviour that is deemed to
be ‘unusual’. Three key areas of the topic are covered: the procedures

involved in the diagnosis and classification of mental disorders (such
as schizophrenia); research into the history and origins of multiple
personality disorder; and a discussion of the implications of cultural
variability (including culture-bound syndromes) for the classification
and diagnosis of psychological abnormality.
Classification and Diagnosis of Abnormal Psychologyis an intro-
ductory text suitable for students and teachers of the AQA Psychology
A2 specification and is also useful for other groups who work in the
field of mental disorder, such as nurses, social workers and therapists.
Sue Caveis a senior examiner and coursework moderator for A level
Psychology, and a lecturer at the University of Kent.
Routledge Modular Psychology
Series editors: Cara Flanagan is a Reviser for AS and A2 level
Psychology and lectures at Inverness College. Philip Banyard is
Associate Senior Lecturer in Psychology at Nottingham Trent
University and a Chief Examiner for AS and A2 level Psychology.
Both are experienced writers.
The Routledge Modular Psychology series is a completely new
approach to introductory-level psychology, tailor-made to the new
modular style of teaching. Each short book covers a topic in more detail
than any large textbook can, allowing teacher and student to select
material exactly to suit any particular course or project.
The books have been written especially for those students new to
higher-level study, whether at school, college or university. They
include specially designed features to help with technique, such as a
model essay at an average level with an examiner’s comments to show
how extra marks can be gained. The authors are all examiners and
teachers at the introductory level.
The Routledge Modular Psychologytexts are all user-friendly and
accessible and include the following features:
• practice essays with specialist commentary to show how to achieve
a higher grade;
• chapter summaries to assist with revision;
• progress and review exercises;

• glossary of key terms;
• summaries of key research;
• further reading to stimulate ongoing study and research;
• cross-referencing to other books in the series.
