Because of the well-documented effectiveness of paradigms which emphasize parental or family pathology in understanding and intervening with dysfunctional children, the temptation exists for applying them to other dysfunctional populations. Autism is a pervasive developmental dysfunction with life-long adverse sequelae for the child and family. This paper reviews evidence on the biological etiology of autism and other pervasive developmental deviations, and stresses the necessity forproviding an early and accurate diagnosis for the family. The adverse implications of downplaying individual pathology and concentrating on parental or family dysfunction are then discussed. The natural evolution and specific components of a psychoeducational model for diagnosing autistic children and working with them and their families are then presented. Finally, some of the advantages of this multimodal, multidiscipline model in long-term work with these pervasively dysfunctional individuals and their families are considered.A systemic approach to understanding psychopathology has had a distinct appeal to many mental health workers because it allows for a complete and balanced view of an individual's pathological behavior. Although the relative emphasis placed on individual versus family variables differs across systemic paradigms (cf. Schwartz & Johnson, 19851, by and large family therapists subscribe to the notion of the identified patient (IP) (Haley, 1980). They usually see the IP as the most vulnerable family member, whose dysfunctional behavior allows the remaining members of the family to maintain their homeostatic, albeit pathological balance. In the case of schizophrenia, for example, most systemic theorists' three main assumptions are that: (a) schizophrenia is intrafamilial rather than physical; (b) the family, in a transactional way, chooses its ill members; and (c) the illness is an advantage, in that it allows the family to maintain its homeostatic balance (Terkelsen, 1983). In this conceptualization, treatment of the IP is a futile exercise since the entire family constitutes the proper intervention target.
