N2 - Objectives: To assess the reliability and validity of a brief screening instrument, "E-HITS" (Extended - Hurt, Insult, Threaten, Scream), for detecting female intimate partner violence (IPV) in Hong Kong emergency departments (EDs). Method: Quantitative data were collected from a victim group (n=110) and a control group (n=116). Statistical properties of the instruments were analysed to ascertain its internal consistency, test/re-test reliability, concurrent validity and discriminant validity. Results: Cronbach's alpha was 0.90 for the E-HITS. Two-week test/re-test reliability was 0.71 (p<0.001). Respondents' scores on the E-HITS positively correlated with those on psychological aggression, physical assault, sexual coercion and injury scales, and negatively correlated with the negotiation scale of the revised Conflict Tactics Scale at a statistically significant level. Subsequent Receiver Operating Characteristic (ROC) curve analysis revealed that E-HITS reached a sensitivity of 98.2% and a specificity of 94.8% at a cut-off of 8.5. The overall accuracy of the E-HITS indicated by the area under curve (AUC) in the ROC is 0.991. Conclusion:These results show that the E-HITS has good internal consistency, test/re-test reliability, as well as concurrent and discriminant validity. The E-HITS is a valid and reliable tool for screening intimate partner violence in Hong Kong EDs.
