Validation of the parent version of the World Health Organization Adult ADHD Self-Report Scale
for adolescents
Sammanfattning
Objective: To investigate the validity of a parent version of the World Health Organization Adult
Attention-Deficit/Hyperactivity Disorder (ADHD) Self-Report Scale for adolescents (ASRS-AP) and the
6-question screening version (ASRS-AP-S). Methods: Adolescent psychiatric outpatients (N = 112,
mean age 15 years, 40% boys) and their parents were interviewed with the Kiddie Schedule of
Affective Disorders and Schizophrenia (K-SADS), and the parents reported on the ASRS-AP/ASRS-AP-
S. Results: Internal consistency (Cronbach’s alpha) was 0.93 for ASRS-AP and 0.85 for ASRS-AP-S,
0.91 and 0.87 for the inattention subscale, and 0.91 and 0.72 for the hyperactivity subscale,
respectively. The concurrent validity (Spearman’s correlation coefficient) between the total K-SADS
ADHD symptom severity score and the sum of the score on the ASRS-AP/ASRS-AP-S was 0.75 and
0.66, respectively. Diagnostic accuracy measures for the ASRS-AP and ASRS-AP-S were 78% and 80%
sensitivity, 75% and 74% specificity, 73% and 71% positive predictive value (PPV), and 81% and 82%
negative predictive value (NPV), respectively. Conclusions: The ASRS-AP and ASRS-AP-S showed
high internal consistency and concurrent validity in relation to total K-SADS ADHD symptom severity
score. Both scales showed favourable diagnostic accuracy measures.
