Understanding cross-cultural aspects of emotional overin-volvement (EOI) on psychosis outcomes is important for ensuring cultural appropriateness of family interventions. This systematic review explores whether EOI has similar impact in different cultural groups and whether the same norms can be used to measure EOI across cultures. Thirty-four studies were found that have investigated the impact of EOI on outcomes across cultures or culturally adapted EOI measures. The relationship between high EOI and poor outcome is inconsistent across cultures. Attempts to improve predictive ability by post hoc adjust-ment of EOI norms have had varied success. Few studies have attempted a priori adaptations or development of cul-ture-specific norms.Methodological differences such as use of different expressed emotions (EE) measures and varyin
