For the primary efficiency measurements the project uses: ADHD-RS-IV (Attention Deficit Hyperactivity Disorder Rating Scale fourth edition), a scale for evaluating the severity of the ADHD symptoms, SDQ-DAN (Strengths and Difficulties Questionnaire - Danish translation) focuses upon the child's strengths and weaknesses in accordance with activity and attention, emotional problems, behavioural difficulties etc. For the secondary efficiency measurements the project uses: TCA (Treatment Compliance Assessment) (Halperin et al: in press), which establishes how much time the child spends on each TEAMS activity and television/computer games each day. Each day the parents fill out the TCA, as part of a logbook which also describes compliance with the TEAMS treatment project.
