This study was conducted for the distinct purpose of describing treatment services and clientele of four high profile treatment programs.

A validation study uses extensive statistical analysis regarding the instrument's demonstrated ability to predict certain outcomes. The primary goal of this validation study was to determine how well the LSI predicts outcomes on three related measures: 1) any form of recidivating behavior; 2) the commission of a new misdemeanor or felony; and 3) program termination status.
