This paper describes the Developmental Knowledge and Management Practices Scale. It is designed for assessing the primary care physicians' knowledge of development and their management practices when faced with children exhibiting evidence of handicap. The scale may be useful for assessing the inservice training needs of primary care physicians with respect to child development and case management, and for evaluating preservice and inservice programs designed to meet those needs. The content areas of development assessed by this scale include affective, temperament, social, cognitive, language, sensory, gross motor and five motor skills. Sample items and an answer key are also included. The primary care physician is the professional with one of the best opportunities for early detection of developmental difficulty in children. Currently available evidence suggests, however, that these physicians are not referring developmentally disabled infants and young children for services as rapidly as possible. Several explanations are offered for this delay in referral. (DWH)
