SDQ emotional problems/disorder tested against high risk of any emotional disorder (generalized anxiety disorder, specific phobia, social phobia, panic disorder/agoraphobia, obsessive–compulsive disorder, major depression); SDQ hyperactivity/hyperactivity disorder tested against high risk of any ADHD/hyperkinesis disorder; high risk of disorder was defined as having DAWBA clinical rater diagnosis and/or definite diagnosis recorded in clinical notes. SDQ borderline/abnormal and possible/probable ratings were collapsed and contrasted to normal or unlikely ratings. Sens: sensitivity, Spec: specificity, PPV: positive predictive value, NPV: negative predictive value. n = 77. Power achieved for: emotional problems parent‐report SDQ = 99%; self‐report SDQ = 49%; multi‐rater algorithm = 99%; hyperactivity parent‐report SDQ = 95%; self‐report SDQ = 50%; multi‐rater algorithm = 97%.
