However, a number of inmates who were initially tested on the REST and CRC had been
admitted prior to January 1,2000, when the study began, and were thus unavailable for repeated
testing six months later (time 2) and twelve months later (time 3) because they had already
completed their programs or been terminated. Mean REST and CRC scores for each testing
period are presented in Tables 9 and 10. In subsequent statistical analyses, we selected out only
those inmates who were admitted after January 1,2000 to provide a cleaner chronology of
repeated measures (Le., most of these inmates were actually tested close to the proper 1 -month,
ti-month, and 12-month intervals after their admission to TC). This procedure reduced the
potential TC sample fi-om 742 to 395 inmates." While we were able to track recidivism for the
entire sample of 742 TC inmates, therefore, only 395 were actually admitted during the study
period and subject to repeated administrations of the REST and CRC.

Although the TC attrition rate was only 25% overall, many inmates were paroled or
successfblly discharged fiom TC before they could complete all three intended administrations of
the REST (Le., 1-month, &month, and 12-months post-admission). Since a maximum of 395 TC
inmates admitted after January 1,2000 were actually subject to repeated REST and CRC testing,
this smaller sample was used to examine changes on the REST and CRC subscales over time.
Because only a small portion of all TC inmates admitted after Jan~wy 1,2000 actually remained
in TC programs 12 months later at the third measurement interval (Le., only 32 inmates for the 3rd
REST, and only 43 inmates for the 3rd CRC), we focus instead on the much larger samples
available for analyzing differences fi-om time 1 (n = 321 for the 1' REST, n = 320 for the 1' CRC)

Social Conformity (#18,27), and Treatment Readiness (#7, 19,34,44). Reverse-scored items on
the CRC included items #6, 7, 8, 9, 11,22, and 23.
