A questionnaire assessing current clinical approach to the problem of childhood hyperactivity was mailed to 910 primary care physicians in the state of Washington. A response of 462 (50.8%) was obtained. Pediatricians assess and manage hyperactivity in a manner significantly different from that of family physicians or general practitioners. Age of physician also accounted for significant differences, although to a lesser degree than type of training. Few differences were determined by size of community. An overall high prevalence of the problem of hyperactivity was apparent. Combined use of stimulant medications, behavioral programs, and special diets was common.
