Brown Attention Deficit Disorder Scale (BADDS) for Adults is a tool to assess Attention Deficit Hyperactivity Disorder (ADHD) and related executive function deficit symptoms. The scale was adapted to Turkish and the psychometric characteristics were analyzed. Group with ADHD (N = 101, 48 Female and 53 Male) and a group without ADHD (N = 251; 213 Female and 38 Male) with age range between 18 to 41 year olds, participated. Confirmatory factor analysis demonstrated adequate fit between the two forms. Test-retest reliability on group without ADHD (n = 53), was .82 (p < .01). Cronbach alpha coefficient (.95) and item-total score correlations confirmed internal consistency. Total scores and five cluster scores of ADHD group (n = 92) and control group (n = 231) were compared for the discriminative validity. The results showed that the total and cluster scores of the ADHD group were significantly higher than the control group (p < .01). Turkish form of BADDS for Adults is found to be reliable and valid scale that can be used in Turkey for the practical and research purposes.
