An inventory is described for assessing medical staffs' knowledge of behavioral methods with pediatric pain patients. It was adapted from a measure designed by Sanders and Webster (1982) for use with nurses treating adult chronic pain patients. The modified inventory was administered to three groups of medical staff: (a) pediatric residents, (b) pediatric nurses and (c) medical students. A series of analyses provided data supporting the psychometric integrity of the inventory. The measure successfully discriminated trained from untrained staff. The utility of the instrument for staff assessment and development is discussed.
