“…Additionally, the measure of recidivism employed here is limited, as it fails to capture arrests that do not lead to a court filing or behavior, such as drug and alcohol use, which if known would result in participant failure. Moreover, previous research has shown that use of official data, such as court filings, tends to underestimate the true prevalence of criminal involvement (Inciardi & Chambers, 1972;Elliot, 1995;Inciardi, McBride, & Rivers, 1996). Therefore, future drug court research should integrate both self report data on illegal or illicit behavior, arrests, and official arrest records (court filings) in order to increase the validity and reliability of recidivism as an outcome measure.…”
