Behavioural psychotherapy is probably now the preferred treatment in as many as 25% of neurotic patients or 12% of adult psychiatric outpatients. It is, of course, part of some psychiatrists' therapeutic repertoire already. However, more widespread use of behavioural methods by psychiatrists would seem to be desirable and this is particularly so as clinical psychologists remain thin on the ground in many places. Indeed clinical psychology remains one of the smallest health-service professions. In 1981 there were 1,105.7 qualified clinical psychologists (whole time equivalents) in England. Moreover this overall figure conceals enormous disparities between Health Authorities, some of which provide good psychological services while others provide virtually nothing. In recognition of the importance of behavioural techniques, the Royal College of Psychiatrists has recommended that experience of them should be an integral part of any psychiatrist's training.
