Psychometric Properties of the Turkish Working Alliance Inventory-Observer Form.

Objective: This study aimed to examine the reliability and validity of the Turkish version of the Working Alliance Inventory-Observer Form (WAI-O) (Titchenor and Hill, 1989). Method: The study included 18 videotape records of 6 therapists conducting short-term cognitive behavioral therapy. The videotape records were chosen randomly from the pool of Hacettepe University Psychotherapy Research Laboratory (HU-PRL) and coded by 3 judges. Intra-class correlation (ICC) coefficients for the scale were calculated using the average measure method to determine the inter judge reliability coefficients for the data obtained from the 3 judges. Result: The ICC coefficients were 0.73, 0.70, and 0.78 for the bond, goal, and task dimensions, respectively. The ICC coefficient was 0.75 for the inventory total score. The internal validity of the scale was α = 0.90. The item total correlation ranged between 0.84 and 0.96. Discussion: On a preliminary basis our findings indicate that the Turkish version of the WAI-O Short Form has acceptable levels of reliability and validity for clinical and research use in Turkey.
