12 monozygotic (MZ) and 19 same‐sexed dizygotic (DZ) twin pairs discordant for DSM‐III‐R schizophrenia completed the Parental Bonding Instrument (PBI). The schizophrenic twins described their parents as less caring and being more overprotective compared to their non‐schizophrenic co‐twins. These results were independent of age, sex and zygosity. Difference in paternal overprotection was the most important variable discriminating between the schizophrenic probands and their co‐twins. Three different hypotheses regarding these findings are discussed.
