brown attention deficit disorder scales test for adults

It is noted that the DSM specifies two subtypes (Inattentive and Hyperactive/Impulsive) however analysis of this scale indicates three distinct symptom clusters. These factors are used to compute subscale scores. Stanton, Forbes and Zimmerman (2018) determined, by using CFA with over 1,000 adult subjects, that the ASRS had three factors: This age specific normative data is used to compute percentiles. Of note, ASRS total scores where significantly related to age: (2018) found that in a sample of 22,397 randomly selected adults in the USA that the mean total score was 2.0 (SD = 3.2). Moreover, the ASRS has moderate specificity (.71) and high negative predictive power (1.0), indicating that this tool is quite successful in not identifying someone with ADHD when they do not have the disorder (Hines, King & Curry, 2012).Īdler et al. Using this scoring convention, previous studies (e.g., Hines, King & Curry, 2012) report high sensitivity (1.0) and moderate positive predictive power (0.52), suggesting that the ASRS would rarely miss ADHD in an adult who has ADHD. The ASRS has high internal consistency (Cronbach’s alpha = 0.88) and concurrent validity (r = 0.84) (Adler et al., 2006).įor a client’s symptoms to be considered consistent with an ADHD diagnosis, they require 4 or more responses in the criterion boxes of Part A (the first 6 questions) of the ASRS. For a client’s symptoms to be considered consistent with an ADHD diagnosis, they require 4 or more responses at specific severity levels in Part A of the ASRS.

Part-B contains 12 additional questions based on DSM criteria that provide additional cues and can serve as further probes into the patient’s symptoms. Part A contains 6 items and it has been found that these questions are the most predictive of ADHD and are best for use as a screening instrument. This scale is useful for screening and diagnosis of ADHD among adults 18+ and should be used in conjunction with a clinical interview to provide additional clinical information. This scale is based on the World Health Organization Composite International Diagnostic Interview (2001), and the questions are consistent with DSM criteria, but reworded to better reflect symptom manifestation in adults. The Adult ADHD Self-Report Scale (ASRS v1.1) is an 18-item self-report questionnaire designed to assess Attention Deficit Hyperactivity Disorder (ADHD) symptoms in adults (18+).
