Abstract


Clinical assessment tools for adult attention deficit hyperactivity disorder (ADHD) such as rating scales, interviews and behavior observations are often based on subjective judgments which enhance the risk of overlooking or misinterpreting symptoms. In search for objective measures of adult ADHD, the present study investigated levels of sensitivity and specificity for the Quantified Behavior Test Plus, QbTest-Plus, in adult patients (N = 19) awaiting clinical assessment for ADHD. QbTest-Plus report objective measures of ADHD core symptoms using an infrared motion tracking system and a continuous performance test. The measures were collected and evaluated previous to clinical assessment and compared regarding the diagnosis of ADHD. Sensitivity for detecting ADHD with QbTest-Plus was 83 % and specificity was 57 %. The results, possibly affected by confounding factors, suggest further examination of calibrated and objective measure for the QbTest-Plus with regard to ADHD in adults.
