Background: As the diagnostic criteria for psychosomatic research-structured interview (DCPR-SI) is a rater-assessed questionnaire, it has not been used vastly in community-based studies and clinics. Describing and investigating self-assessed form of DCPR are an attempt to apply it easier and more worthwhile for medical settings. The aim of this study was to describe and present self-assessed form of DCPR self-assessed (DCPR-SA) and test its validity and reliability. Materials and Methods: The DCPR-SI was translated to Persian according to the best practice methodology and the guideline for adaptation of self-report measures. In this cross-sectional study, 540 patients and healthy individuals were recruited and answered DCPR-SA and some related questionnaires. Inter-rater (test–interview) and test–retest reliability were determined. Construct, concurrent, discriminant, and known-group validity were tested. Results: The kappa coefficients were expressed substantial and almost perfect agreement (0.617–0.784, P ≤ 0.05). In addition, phi correlation coefficients were indicated adequate test–retest reliability for each cluster (0.548–0.754, P ≤ 0.05). Three domains (anxiety-related symptoms, functional symptoms, and dysfunctional traits and emotional patterns) were confirmed by factor analysis. The results of the discriminate validity analysis were promising. Conclusion: The findings show that the DCPR-SA is valid and reliable and can be used by medical professionals as a psychosomatic screening tool and can be used properly in Persian-speaking population.
