Background This study examined the relationship between discrepancies in beliefs about schizophrenia and Expressed Emotion (EE) in family dyads. Method Illness beliefs were assessed in patients with a diagnosis of schizophrenia and their relatives (N=49 dyads). The degree and the direction of discrepancy were calculated, and comparisons were made between dyads in which the relative was rated as high EE and dyads in which the relative was rated as low EE. Results There was greater discrepancy between illness models of schizophrenia in dyads involving a high-EE relative than in dyads involving a low-EE relative. This difference was not accounted for by the differences in either relatives' or patients' beliefs alone. Conclusion Further research is needed to understand EE in the context of discrepancies in beliefs between patients and relatives rather than focussing on relatives' beliefs alone.
