摘要
Increasingly, emphasis is being placed on measurement-based care to improve the quality of treatment. Although much of the focus has been on depression, measurement-based care may be particularly applicable to social anxiety disorder (SAD) given its high prevalence, high comorbidity with other disorders, and association with significant functional impairment. Many self-report scales for SAD currently exist, but these scales possess limitations related to length and/or accessibility that may serve as barriers to their use in monitoring outcome in routine clinical practice. Therefore, the aim of the current study was to develop and validate the Clinically Useful Social Anxiety Disorder Outcome Scale (CUSADOS), a self-report measure of SAD. The CUSADOS was designed to be reliable, valid, sensitive to change, brief, easy to score, and easily accessible, to facilitate its use in routine clinical settings. The psychometric properties of the CUSADOS were examined in 2415 psychiatric outpatients who were presenting for treatment and had completed a semi-structured diagnostic interview. The CUSADOS demonstrated excellent internal consistency, and high item-total correlations and test-retest reliability. Within a sub-sample of 381 patients, the CUSADOS possessed good discriminant and convergent validity as it was more highly correlated with other measures of SAD than with other psychiatric disorders. Furthermore, scores were higher in outpatients with a current diagnosis of SAD compared to those without a SAD diagnosis. Preliminary support also was obtained for the sensitivity to change of the CUSADOS in a sample of 15 outpatients receiving treatment for comorbid SAD and depression. Results from this validation study in a large psychiatric sample show that the CUSADOS possesses good psychometric properties. Its brevity and ease of scoring also suggest that it is feasible to incorporate into routine clinical practice.
