Bias refers to systematic errors that result from the way the study was designed, executed, or interpreted
-
Uses “cycles of time” to equally expose subjects to different settings in a repeated way across the day
- For ADHD studies, subjects cycle between the analogue classroom and structured activities
- Uses age and developmentally appropriate activities and environmental modifications for preschool and school-aged children
-
Allows for systematic collection of information deemed to be critical in the standard clinical practice of treating disruptive behavior disorders with medication
- Dosing, safety, attention, behavior, and classroom productivity
-
Pharmacodynamic (PD) and pharmacokinetic (PK) information can be collected simultaneously
-
Safety measurements include pulse rate, blood pressure, electrocardiogram, and side effect ratings
