We aimed to adapt The Partner Interaction Questionnaire developed by Cohen and Lichtenstein (1990) to Turkish in this study. The inventory is originally in English, and it consists of 24 items in the original form. The Partner Interaction Questionnaire has two subscales (Negative Behaviors and Positive Behaviors). A team of two academics (a family physician and a clinical psychologist) translated the original to the Turkish language, and 11 qualified experts who have a good command of English and are studying in the field of smoking cessation created an expert opinion form (Krippendorff’s alpha = .93). A total of 611 smokers who had admitted to the Ondokuz Mayıs University Family Medicine Smoking Cessation Clinic filled the Partner Interaction Questionnare-20 in Turkish (PIQ-20-TR) at their first visit. One month later, the PIQ- 20-TR was re-administered to these participants (re-test, n = 598). Cronbach’s alpha for the total PIQ-20-TR was .92; for the negative subscale it was .85; and for the positive subscale it was .87. There was a statistically significant relation between the re-test and test scores of both the positive and negative subscales (p < .001). The confirmatory factor analyses and fit indexes revealed a high validity of the PIQ-20-TR (X2/sd = 2.131; root mean square error of approximation = 0.054; goodness of fit index = 0.902; adjusted goodness of fit index = 0.933; normed fit index = 0.963, incremental fit index = 0.971; and the comparative fit index = 0.97).
