Abstract

Background: The aim of this study was to investigate the psychometric properties of the Persian version of the Screen for adult anxiety related disorders (SCAARED) in Tehran. Method: The present study was a descriptive-survey method and a cross-sectional method. The present research population consists of patients referring to hospitals and psychiatric clinics in Tehran, as well as male and female students in Tehran. The sample of the present study included 300 participants (150 patients with a diagnosis of anxiety disorders and 150 non-clinical samples), who were selected by random sampling method.

Also, the results showed a correlation between the two implementations of the questionnaire; in addition to the strong correlation at the level (p
