A psychological and psychiatric study of 11 children with cystic fibrosis revealed major psychological problems in all of them. Among the parents of the majority of these children, marked psychopathology and gross marital discord were noted. Popular literature concerning cystic fibrosis had a negative effect on the child's attitude toward the disease. Virtually all of these patients showed a preoccupation with death. In this study, the necessity of psychiatric consultation as an integral part of current intensive treatment programs in cystic fibrosis clinics was demonstrated.
