The prevalence of suicidal behavior among preadolescent children who are psychiatric inpatients.

The prevalence of suicidal behavior displayed by preadolescent children hospitalized on inpatient psychiatric units is estimated to range between 18% and 80% of the population. The current study provides an independent estimate of the prevalence of this problem. A semistructured interview was used to assess suicidal behavior displayed by 61 admissions to a child psychiatric inpatient unit between April 1988 and September 1989. According to the Pfeffer Spectrum of Suicidal Behavior Scale, 63% of the sample engaged in some form of suicidal behavior. Preadolescents and their parents reported similar rates of suicidal thoughts, threats and attempts. The dangerousness of recent suicidal behavior was not found to differ by age, sex, legal custody status or socioeconomic status.
