ADHD symptom trajectories in parent ratings. ADHD symptom trajectories in parent ratings from Visit 1 to Visit 3 in the four-class solution of the conditional growth mixture model (N = 822); time corresponds to the average time the visits took place. ADHD = attention deficit hyperactivity disorder; FBB-ADHD = German ADHD Symptom Checklist (Fremdbeurteilungsbogen für Aufmerksamkeitsdefizit-Hyperaktivitätsstörung). High-start = subgroups with more severe symptoms compared with the low-start group at Visit 1; mixed-response = in parent ratings, comparatively stronger treatment response is observed during Visit 2 to Visit 3 and in teacher ratings during Visit 1 to Visit 2; first-phase response = in parent and in teacher ratings comparatively stronger treatment response is observed during Visit 1 to Visit 2; low-response = compared with other subgroups, only minor symptom reduction is detected during the observational period.
