Abstract
Based upon clinical considerations, scales were developed measuring client perceptions across four interrelated domains: circumstances (external pressures), motivation (intrinsic pressures), readiness, and suitability (CMRS) for residential TC treatment. This paper, the first in a series, reports findings on the reliability of the CMRS and its validity as a predictor of retention in TC treatment in three cohorts of consecutive admissions to a long-term residential TC. The main findings show that: (a) discriminant and factor analyses confirm the face validity of the original four rationale scales; (b) scores distribute into four groups, with most clients in the moderately low to moderately high range; (c) two cross-validation studies confirm the internal consistency of the scales, and a linear relationship between the separate and total CMRS scores and short-term retention in all three cohorts and long-term retention in two cohorts. The present psychometric study provides impressive findings on the reliability and validity of the CMRS scales as predictors of retention in long-term TCs. Although still considered experimental, awaiting replicational studies and firm conclusions concerning generalizability, the CMRS holds considerable promise for research, theory, and practice.
