Abstract

Abstract Objective: The use of early response/nonresponse (ER/ENR) to antipsychotics as a predictor for ultimate response/nonresponse (UR/UNR) may help decrease inefficacious treatment continuation. However, data have been limited to adults, and ER/ENR has only been determined using time-consuming psychopathology rating scales. In the current study, we assessed if early improvement on the Clinical Global Impressions-Improvement (CGI-I) scale predicted UR/UNR in psychiatrically ill youth started on antipsychotic treatment. Methods: Seventy-nine youth aged 6-19 years, with schizophrenia spectrum disorders, treated naturalistically with aripiprazole, olanzapine, quetiapine, risperidone, or ziprasidone and evaluated monthly, were divided into ER/ENR groups at week 4, using at least "minimally improved" on the CGI-I scale. Prediction using week 4 ER/ENR status for UR (CGI-I=at least "much improved"), effectiveness and adverse effect outcomes at 8-12 weeks were assessed. Results: At 4 weeks, 45.6% of subjects were ER and 54.4% were ENR without differences regarding baseline demographic, illness, and treatment variables, except for higher age (p=0.034) and maximum risperidone dose (p=0.0043) in ENR. ER/ENR status at 4 weeks predicted UR/UNR at week 12 significantly (p
