Interchangeability of the Working Alliance Inventory and Working Alliance Inventory, Short Form.

Author information

Department of Psychology, University of North Dakota, USA.


Working Alliance Inventory (WAI) ratings were compared with ratings comprising the 12-item WAI, Short Form (WAI-S). Responses were collected from 54 university counseling center client-therapist pairs after the 4th therapy session as well as at a final ratings point. WAI and WAI-S scores were highly correlated and had comparable descriptive statistics, internal consistencies, and subscale intercorrelations within and across rater perspectives. Predictive validity estimates for WAI and WAI-S total scales were also very similar. Fourth-session WAI and WAI-S scores were moderately predictive of therapy improvement ratings. Results support the interchangeability of scores on the WAI and WAI-S scales.
