[Validity and reliability of the ASRS and WURS-25 scales for the diagnosis of attention deficit hyperactivity disorder in an Argentinian population].

Abstract

INTRODUCTION\nAttention deficit hyperactivity disorder (ADHD) is a high-prevalence condition: an estimated 2-4% of adults have it. For its diagnosis it is important to know both the presence of symptoms in the present and during the childhood, for which self-administered tools are a valuable resource.\n\n\nOBJECTIVES\nValidate the ASRS and WURS25 scales (abbreviated version of the WenderUtah scale) in Argentine population, as well as provide norms for their application.\n\n\nSUBJECTS AND METHODS\nA general population sample of 1173 volunteers recruited from the internet was used, as well as a clinical sample of 80 patients with ADHD, both completed the scales and a sociodemographic questionnaire. Statistical studies were conducted to verify the internal validity and factorial consistency of the ASRS subscales (corresponding to inattention, hyperactivity and combined) and the two samples were compared to assess the external validity of the test.\n\n\nRESULTS\nThe data obtained showed statistical behavior like the original versions of the tests, adequate levels of internal consistency and clinical discrimination. There were no significant differences depending on the gender of the participants or by age in subjects aged 18 to 50 years. However, subjects over the age of 50 scored higher in the ASRS.\n\n\nCONCLUSIONS\nThe ASRS and the WURS-25 meet the expected internal consistency and external validity criteria in the Argentine population.
