Abstract: | A relationship between various medical illnesses and the frequency and severity of nonspecific behavioral symptoms such as aggression and self-injury has been described by a number of writers. None, however, provides a clinical case formulation model that articulates the specific nature of this relationship or the manner in which potential biomedical influences interact with psychological and socioenvironmental ones to determine the occurrence and strength of behavioral symptoms. A model is described in this paper that suggests possible contributions of medical illnesses or conditions to occurrence of nonspecific behavioral symptoms and provides a diagnostic basis for selecting and evaluation related interventions. © 1997 John Wiley & Sons, Ltd. |
