Measuring patient attributes and engagement in treatment.
Brief but comprehensive instruments measuring patient motivation, psychosocial functioning, treatment process, social network support, and services received are needed for monitoring drug abuse treatment delivery and patient progress. Combining this information across patients within a program also provides useful indicators about institutional composition and functioning. Consequently, the same assessment tools can be used to identify areas where treatment protocols need to be changed, and to monitor improvements following such changes. The Texas Christian University (TCU) Client Evaluation of Self and Treatment (CEST)(1) is a 144-item self-rating instrument that includes 16 scales measuring patient functioning and treatment perceptions. Psychometric properties (including reliability and construct validity) of the scales are examined in this article, based on patient samples drawn from 87 programs that participated in a series of staff training workshops. Acceptable reliabilities (.70 or above) were generally reported, and construct validity was also demonstrated (although the confirmatory factor analyses suggested some item pools could represent more than one factor). Prediction analyses were conducted using selected scales from each measurement domain to illustrate their sensitivity to treatment program contexts.
