PSYCHOMETRIC CHARACTERISTICS OF THE WENDER UTAH RATING-SCALE (WURS) -RELIABILITY AND FACTOR STRUCTURE FOR MEN AND WOMEN

The goals of this study were to examine the factor structure of the We nder Utah Rating Scale (WURS), to evaluate potential gender difference s in factor composition, and to assess the reliability of the scale. T he WURS was completed by 310 fathers and 305 mothers of children refer red 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 fo r 71 percent of the variance. Symptoms of inattention and impulsivity loaded on separate factors for both men and for women. Test-retest rel iability was examined with a different sample of 57 adults who complet ed the WURS on two separate occasions, 1 month apart. The WURS demonst rated satisfactory internal consistency and temporal stability, and it may be a useful tool for the study of ADHD in adults.
