The client satisfaction questionnaire. Psychometric properties and correlations with service utilization and psychotherapy outcome.

Abstract

An 18-item version of the Client Satisfaction Questionnaire (CSQ-18) was included in an experimental study of the effects of pretherapy orientation on psychotherapy outcome. The psychometric properties of the CSQ-18 in this study were compared with earlier findings. In addition, the correlations of the CSQ-18 with service utilization and psychotherapy outcome measures were examined. Results indicated that the CSQ-18 had high internal consistency (coefficient alpha = .91) and was substantially correlated with remainer-terminator status (rs = .61) and with number of therapy sessions attended in one month (r = .54). The CSQ-18 was also correlated with change in client-reported symptoms (r = -.35), indicating that greater satisfaction was associated with greater symptom reduction. Results also demonstrated that a subset of items from the scale (the CSQ-8) performed as well as the CSQ-18 and often better. The excellent performance of the CSQ-8, coupled with its brevity, suggests that it may be especially useful as a brief global measure of client satisfaction.
