Discriminant of Validity the Wender Utah Rating Scale in Iranian Adults

The aim of this study is the normalization of the wender utah rating scale which is used to detect adults with attention-deficit and hyperactivity disorder (adhd). available sampling method was used to choose 400 parents of children (200 parents of children with adhd as compared to 200 parents of normal children). wender utah rating scale, which has been designed to diagnose adhd in adults, is filled out by each of the parents to most accurately diagnose of adhd in parents. wender utah rating scale was divided into 6 sub scales which consist of dysthymia, oppositional defiant disorder; school work problems, conduct disorder, anxiety, and adhd were analyzed with exploratory factor analysis method. the value of (kaiser-meyer-olkin) kmo was 86.5% for dysthymia, 86.9% for oppositional defiant disorder, 77.5% for school related problems, 90.9% for conduct disorder, 79.6% for anxiety and 93.5% for attention deficit/hyperactivity disorder, also the chi square value based on bartlett’s test was 2242.947 for dysthymia, 2239.112 for oppositional defiant disorder, 1221.917 for school work problems, 5031.511 for conduct, 1421.1 for anxiety, and 7644.122 for adhd. since mentioned values were larger than the chi square critical values (p<0.05), it found that the factor correlation matrix is appropriate for factor analysis. based on the findings, we can conclude that wender utah rating scale can be appropriately used for predicting dysthymia, oppositional defiant disorder, school work problems, conduct disorder, anxiety, in adults with adhd.
