Persian Manuscript of Adult Attention Deficit Hyperactivity Disorder Rating Scale Expected Internal Consistency and Factor Structure in Iranian Medical Students

Abstract

Background: Adult attention-deficit/hyper activity disorder (ADHD) interacts with educational and occupational achievements. To introduce a valid screening tool for adult ADHD in Iranian students, the current study aimed at evaluating internal consistency and factor structure of adult ADHD self-report scale (ASRS) Persian version 1.1. Methods: ASRS Persian version 1.1 was filled by 240 Iranian medical students aged 18 - 24 years, and Cronbach’s alpha coefficient and factor analysis were performed with SPSS version 21. Results: Cronbach’s alpha coefficient was 0.76.8 for ASRS. Factor analysis confirmed two factors of attention deficit and hyperactivity for ASRS Persian version. Conclusions: ASRS Persian version 1.1 had adequate internal consistency and saved the two structure factors of the original questionnaire, the hyperactivity and the attention deficit.
