A substantial minority of people with severe learning disabilities behave
in ways that cause problems for themselves, their carers and other members of
society. This is frequently a reason for referral to a psychiatrist.
Challenging behaviour has become the preferred term in recent years to
describe such behaviours because it emphasises the social context. Professor
Emerson, a psychologist well-known for his own research in the field of
behavioural interventions, has written a comprehensive summary of current
thinking about challenging
behaviour.
The opening chapter defines challenging behaviour as a social construction
and later states that it is not a psychiatric diagnosis, although it
may be a secondary feature of a psychiatric disorder. The second
chapter describes the impact of challenging behaviour on the health, safety
and quality of life of both the sufferer and his/her carers, which is
inevitably significant. A detailed chapter on epidemiology follows, showing
that these behaviours are common and tend to be persistent over years or even
decades. Theoretical models are discussed in the fourth chapter. The book is
concerned primarily with psychological and specifically behavioural approaches
but in this second edition Emerson has expanded the section on neurobiological
models and psychiatric disorders and this is welcome.
The remaining chapters cover functional analysis, behavioural
interventions, psychopharmacological interventions, the effectiveness of
community-based supports and the challenges for future research. Although
Emerson supports all his comments with references, the number of good case
controlled studies to support either pharmacological or behavioural
interventions is disappointingly small. The range of methods used by
psychologists to measure and influence challenging behaviour are effectively
communicated, and the usefulness of the various techniques is helpfully
summarised in tables. The ethical implications of each model are
considered.
There are some omissions, for example the section on psychiatric disorders
does not include consideration of the possible role of psychotic illness, the
role of anxiety disorders is given insufficient attention and there is no
discussion of the possible usefulness of a psychodynamic understanding and
treatment of challenging behaviour. However, the book does succeed in its
stated aim of providing a concise introduction to the field and drawing
attention to recent advances in applied behaviour analysis. For this reason,
and for its extensive references, I commend it to learning disability
psychiatrists and other professionals who work with people who have learning
disabilities and whose behaviour is challenging.
