The goals of this study were to examine the factor structure of the Wender Utah Rating Scale (WURS), to evaluate potential gender differences in factor composition, and to assess the reliability of the scale. The WURS was completed by 310 fathers and 305 mothers of children referred for evaluation of Attention-Deficit Hyperactivity Disorder (ADHD). For males, a five-factor solution (Conduct Problems, Learning Problems, Stress Intolerance, Attention Problems, Poor Social Skills/Awkward) accounted for 72 percent of the variance. There was also a five-factor solution for females (Dysphoria, Impulsive/Conduct, Learning Problems, Attention and Organizational Problems, Unpopular) which accounted for 71 percent of the variance. Symptoms of inattention and impulsivity loaded on separate factors for both men and for women. Test-retest reliability was examined with a different sample of 57 adults who completed the WURS on two separate occasions, 1 month apart. The WURS demonstrated satisfactory internal consistency and temporal stability, and it may be a useful tool for the study of ADHD in adults.
