Objective : The Working Alliance Inventory–Short Revised (WAI-SR) has been reported as a reliable, valid and widely used tool for measuring therapeutic alliance. The aim of this study was to assess the reliability and validity of the Korean version of WAI-SR (WAI-SR-K).

Methods : A sample of 196 outpatients completed the WAI-SR-K and the data were analyzed for internal consistency and factor structure. Additionally 51 outpatients re-filled WAI-SR-K after two weeks for the test-retest reliability. To test for the validity, questionnaires of treatment satisfaction, and scales including the Korean version of Drug attitude inventory-10 (K-DAI-10) and Hospital anxiety and depression scale (K-HADS) were administered.

Results : Internal consistency of WAI-SR-K was good (Cronbach's alpha=0.928) and an exploratory factor analysis revealed a two-factor structure. The WAI-SR-K showed a reasonable test-retest reliability (r=0.810, p<0.01). The total score of WAI-SR-K was positively correlated with K-DAI-10 (r=0.276, p<0.01), and negatively correlated with scores of K-HADS-D (r=-0.217, p<0.01) and K-HADS-A (r=-0.159, p<0.05).

Conclusion : The Korean version of Working Alliance Inventory–Short Revised proved to be a reliable and valid instrument for measuring therapeutic alliance in Korean patients with depressive symptoms.
