The Wender Utah Rating Scale: Adult ADHD diagnostic tool or personality index?

OBJECTIVE

The Wender Utah Rating Scale (WURS) is used to retroactively assess ADHD symptoms. This study sought to determine whether the WURS actually functions as an index of dysfunctional personality traits.

METHOD

Five hundred twenty-two adult participants completed the WURS and at least one of the following measures: Wechsler Adult Intelligence Scale-III (WAIS-III), Trails Making Test (Forms A and B), Conners' Continuous Performance Test, d2 Test of Attention, and the Personality Assessment Inventory (PAI).

RESULTS

The WURS correlated significantly with all PAI clinical and treatment scales; however, of the neuropsychological measures, only the CPT significantly correlated with the WURS score. Multiple regression analyses revealed a significant model that included clinical and treatment scales from the PAI as well as working memory and processing speed indexes from the WAIS-III that accounted for 39% of the variance in WURS scores.

CONCLUSION

Performance on the WURS was more related to dysfunctional personality traits than to actual attentional performance in this young adult sample. (J. of Att. Dis. 2009; 13(1) 87-94).
