Purpose of the Scale

The primary aim of the ASRS-40 is to diagnose both subtypes of Attention Deficit Hyperactivity Disorder (ADHD) based on the DSM-IV criteria.

Scale Analysis

The scale was developed by Wolraich et al. (1999) and consists of 40 items corresponding to: 18 questions aligned with the DSM-IV criteria for the two ADHD subtypes (inattention and impulsivity-hyperactivity). 8 additional questions related to impulsivity-hyperactivity. 7 questions assessing conduct disorder. 7 questions evaluating anxiety and depression according to DSM-IV.
The scale was tested in an epidemiological study with a sample of 600 children from six schools in Thessaloniki, aged 6 to 9 years.

Scoring and Statistical Analysis

Responses are rated on a 4-point Likert scale, ranging from: 0 = Never, 3 = Very Often. The threshold score for ADHD diagnosis is 6 or higher for both the inattention and impulsivity-hyperactivity subscales. Scores are based on reports from parents and teachers.

Validity and Reliability

The ASRS-40 has demonstrated strong validity and reliability in diagnosing and monitoring ADHD symptoms over time.
