From the 1940s to the 1970s prominent mental health professionals proposed trauma models as a means of understanding schizophrenia, including Harry Stack Sullivan, Frieda Fromm-Reichmann, Theodore Lidz, Gregory Bateson, Silvano Arieti and R.D. Laing. Based on their clinical work they theorised that schizophrenia appears to be induced by children's experiences in profoundly disturbed families and reflect victims attempts to cope with such families and live in societies that are inherently damaging to people's psychological well-being. In the 1950s Sullivan's theory that schizophrenia is related to interpersonal relationships was widely accepted in the United States. Silvano Arieti's book "Interpretation of Schizophrenia" won the American National Book Award in the field of science in 1975. The book advances a psychological model for understanding all the regressive types of the disorder.
