Diagnosis within psychiatry necessarily involves consideration of a
number of different clinical features. In making a diagnosis, individual
psychiatrists tend to vary in the weight they attach to associated psy-
chosocial adversities, or to learning difficulties or to accompanying
somatic disease. By dealing with these features on axes that are separate
from the psychopathological pattern or syndrome, it has proved possible
to record clinically useful information in a manner that is both more
comprehensive and more comparable than that in the usual disease cate-
gory approach.
This volume provides the psychiatric sections of ICD-10 in a multi-
axial form that is adapted for ease of use of those dealing with mental
disorders in childhood and adolescence. Descriptions have been grouped
into axes that have been chosen to provide unambiguous information of
maximum clinical usefulness in the greatest number of cases. Building
on the popular original framework of four axes, the system has been
greatly improved by the inclusion of a new axis for psychosocial situa-
tions and by the addition of a further sixth axis on adaptive level, which
enables clinicians to code an individual's current level of disability.

Introduction
by Professor Sir Michael Rutter
Some 25 years ago, a World Health Organization seminar produced
findings that argued for a multiaxial approach to the classification of
child psychiatric disorder (1). At that time three axes were proposed:
clinical psychiatric syndromes, level of intellectual function and associ-
ated or etiological factors (physical or environmental). Subsequently, the
suggestions included dividing this third axis into its two parts. In 1975,
WHO published a report of trials of these four axes, the first three of
which were taken from the Eighth Edition of the International
Classification of Diseases ICD-8 (2). These trials indicated the increased
reliability associated with the use of the axes. Later in 1975 a multiaxial
schema was introduced in the United Kingdom adding yet one further
axis for specific developmental disorders, which had previously been
included with 'biological factors'. This schema was based on the newly
introduced ICD-9, with a relatively simple list of associated psychoso-
cial situations. Subsequent studies indicated that the reliability of the
psychosocial axis was unacceptably low, and with the prospects that a
new edition of the ICD would be appearing in the 1990s, a working
group was set up to redraft the psychosocial axis, following the same
principles used for the psychiatric disorders in ICD-10. This means that
this axis includes a much more detailed specification of the criteria to be
used for coding each of the separately identified psychosocial stressors.
This book, then, provides a classification of child and adolescent psy-
chiatric disorders that uses the tenth revision of the International
Classification of Diseases (ICD-10), but which places it in a multiaxial
framework. The first four axes use precisely the same diagnostic cate-
gories as in ICD-10, and the same numerical coding, but the categories
have been placed in a somewhat different order so that they fit in with
the muiti-axial format, and so that those most applicable to children and
adolescents appear first. The fifth axis (associated abnormal psychoso-
cial situations) comprises a set of features that are included in ICD-10 as
various 'Z' codes, but are set out in much more detail in this book. The
development of this axis has been described elsewhere (3). The sixth
axis (global assessment of psychosocial disability) is the only one that is
not included as such in ICD-10. It has been added here, however,

because the assessment of disability has been recognized by WHO as an
essential feature in psychiatry (4). The axis is based on the Global
Assessment of Disabilities Scale included in the ICD-10 field trials
which, in turn, was derived from the fifth axis in DSM-III-R (5). The
scale has been slightly modified to make it more appropriate for use with
children and adolescents. Its inclusion here should be regarded as a first
step towards the development of a systematic scheme for assessing
social disability in children and adolescents with psychiatric disorder.
It should be noted that there is a different WHO multiaxial classifica-
tion for adult psychiatric disorders, comprising just three axes (10).
Principles of a multiaxial framework
Psychiatric diagnosis necessarily involves several different elements. Thus,
it may be desirable to note the type of mental disorder, whether or not there
is mental retardation, and the presence or absence of associated organic
brain disease. In most cases, there is no single diagnostic term that will
include all these and it is necessary to use multiple codings. Of course, the
ICD makes provision for this but there are no rules as to how many cate-
gories to use or the order in which they should be placed. It has been found
that, in practice, psychiatrists vary greatly in their use of multiple categories
(1,2). This has the result that when a condition is not coded it may mean that
the condition was not present, that it was present but not thought important,
or that it was not coded in spite of being thought important. Moreover, there
is no way of determining from the coding which was the case.
The multiaxial scheme was designed to remedy these deficiencies. In
fact, it is no more than a logical development of the ICD multi-category
scheme in which modifications have been introduced specifically to
meet the difficulties noted above. To ensure adequate coverage of data,
and to ensure comparability, three rules are required: (i) a uniform num-
ber of diagnostic elements must be coded (each element having a sepa-
rate axis); (ii) these codings must always refer to the same elements in
diagnosis; and (iii) they must always occur in the same order.
An infinite variety of elements of diagnosis could be included in such
a multiaxial scheme, but for it to be workable in practice, there must be a
quite restricted number of axes. These need to be chosen on the basis of
providing unambiguous information of maximum clinical usefulness in
the greatest number of cases. With regard to child and adolescent psychi-
atry, the axes that were selected refer to the clinical psychiatric syn-
drome (anorexia nervosa, childhood autism, etc.), to the presence or
