In order to carry out an epidemiological survey of child psychiatric disorders in a community sample, the Child Behaviour Checklist was chosen as a parental questionnaire for screening in the first stage of the study. A French version of this instrument was developed and a pilot study of the scale was completed on a clinical sample (N = 127). As a criterion to gauge its validity, the Rutter scale was used as a concurrent measure. The correlation coefficient between the total scores of the two scales is 0·79, and ranges between 0·22 and 0·96 for individual items. A linear regression analysis, using the total score of the Rutter scale as an independent variable, predicts a value of 41 as the optimal cut-off to be used for the Child Behaviour Checklist. Comparative properties (reliability and time of completion) of the two scales are presented and discussed.

The circulation of firearm magazines was used as an index of gun ownership in the states of the USA. States with a higher per capita circulation of firearm magazines had higher suicide rates by gun and higher overall suicide rates. Homicide rates were unrelated to this measure of gun availability. Implications for the prevention of suicide are discussed.

A consecutive series of 45 female bulimic patients treated by one of us was followed four to six years after termination of treatment. Thirty-five (78 %) were successfully followed, six refused to participate in the study and four were untraced. At least seven (16%) had diagnosable bulimia nervosa at follow-up, and at least another seven had a subclinical form of the disorder during the six months prior to follow-up. Relapse into anorexia nervosa was uncommon, and the severity of the bulimic features had improved even among those still diagnosable as having the disorder. Affective disturbances were common among those who were bulimic. The findings were discussed in terms of the intermediate term outcome of the disorder and its identity as a clinical entity.

The General Practice Research Unit (GPRU) was established at the Institute of Psychiatry in the late 1950s, under the honorary directorship of Professor Michael Shepherd. For 30 years it has been staffed by medically qualified workers and social scientists supported, at various times, by the Nuffield Foundation, the Mental Health Research Fund, and the Department of Health and Social Security, as well as by university monies.
