Adult ADHD Self-Report Scale

What it measures?

• The ASRS aims to examine Attention Deficit Hyperactivity Disorder (ADHD) symptoms in adults consistent. Questions are consistent with DSM criteria, but have been modified to better reflect focused symptom manifestation in adults and reduce ambiguities. The ASRS is useful for the screening and diagnosis of ADHD in adults, and should be supplemented by clinical interviews to inform diagnosis and treatment.

Who is it for?

The ASRS has been validated for use in adults aged 18 years and older (Adler et al., 2019).

Instrument Quality

• The ASRS is well-established for use in clinical practice and has strong potentials for adoptions into primary care (Adler et al., 2019). Validation studies have found high internal consistency and concurrent validity with existing ADHD rating scales (Adler et al., 2006) and good test-retest reliability (Matza et al., 2011).

Structure

• 18 items
• Items 1-6 - Part A
• Items 7-18 - Part B
• 2-point Likert scale
• Respondents are asked how often (0 = "Never"; 1 = "Very Often") each statement has applied to them over the past 6 months (e.g. "How often do you feel restless or fidgety?")
• Items 1, 2, 3, 9, 12, 16, and 18 yielded a score of 1 for “Sometimes” whereas the remaining 11 items yielded a score of 0

Scoring instructions

Scores from Part A and B are summed to create a total score and transformed into percentiles appropriate to age-related peers (Adler et al., 2019; Kessler et al., 2005)

Score Interpretation

What higher scores mean?

• Higher scores on Part A suggest an increased number of symptoms associated with Attention Deficit Hyperactivity Disorder (ADHD) and greater likelihood of meeting DSM-IV criteria (Adler et al., 2006; Kessler et al., 2005, 2007) Higher scores on Part B indicate increased symptom count, severity, and functional impact
