Objectives: The aim of this study is to compare the Empirical Behavioral Rating Scale (E-BEHAVE-AD), Neurobehavioral Rating Scale (NBRS), and Neuropsychiatric Interview (NPI) in detecting behavioral disturbance and psychotic symptoms in dementia and characterizing changes in response to treatment. Design: Eighty-seven subjects in the randomized controlled trial %26quot;Continuation Pharmacotherapy for Agitation of Dementia%26quot; were included in this analysis. We compared the detection in, and changes of both agitation and psychosis, using these three instruments. A receiver operating characteristic analysis was performed to compare the performance of the three instruments in detecting global improvement. Results: The instruments were equally likely to detect agitation. The NBRS was most likely to detect psychosis. Although the NPI best detected improvement in agitation, the instruments were equal for detecting improvement in psychosis. In the receiver operating characteristic analysis for overall clinical improvement in response to treatment, there were no differences in the areas under the correlated curves for the three instruments, Nit they demonstrated different sensitivity and specificity at different cutoff points points for target symptom reduction. The E-BEHAVE-AD performed best at a cut point of 30% target symptom reduction and the NBRS and NPI both performed best at 50%. Conclusion: The E-BEHAVE-AD, NBRS and NPI were more similar than different in characterizing symptoms but differed in detecting response to treatment. Differences in sensitivity and specificity may lead clinicians to prefer a specific instrument, depending on their goal and the expected magnitude of response to any specific intervention.
