Discrimination of anxiety disorders by parent ratings: A study based on the Questionnaire for Anxiety and Obsessive-Compulsive Disorders (FBB-ANZ) Abstract. Parent ratings are often used for screening during the diagnostic evaluation of anxiety disorders. Clinically, it is important to correctly differentiate between anxiety and other psychiatric disorders and to distinguish specific anxiety disorders. The present study examined the validity of the screening results obtained by the Parent Questionnaire for Anxiety and Obsessive-Compulsive Disorders (FBB-ANZ). We examined whether the FBB-ANZ discriminated (1) anxiety and other psychiatric disorders and (2) specific anxiety disorders in children and adolescents using ROC analyses. 972 parents of 4;00-11;11-year-old children and 12;00-17;11-year-old adolescents with anxiety disorders, depressive episodes, or externalizing disorders completed the FBB-ANZ. Discrimination of anxiety disorders and externalizing disorders in children (AUC = .72) and adolescents (AUC = .76) as well as depressive episodes in children (AUC = .77) was moderate. Good discrimination of different anxiety disorders was found only for separation anxiety in children (AUC = .84) and adolescents (AUC = .87). The results indicate the limited diagnostic benefit of parent ratings for discriminating different anxiety disorders in children and adolescents. Potential explanations for the results are critically discussed.
