This article examined sociodemographic and clinical characteristics of child treatment completers, and noncompleters who received exposure-based cognitive-behavioral treatment. A total of 137 children (46% girls) and their parents (predominantly Euro-American and Hispanic/Latino) participated in this study (106 completers, 31 noncompleters). The majority of noncompleters, received an average of 5 sessions. Findings were generally consistent with past research in terms of lack of differences between completers; and noncompleters. Results are discussed in the context of previous child attrition research and directions for future research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
