We use a variety of measures and assessment during study visits with the RAD Lab. Though assessments differ across studies, some are more common than others. Below are some of the most common assessments with a bit more information about what they are and why we use them. Any specific questions about what you'll be completing can be directed to your study coordinator.
Children's Depression Rating Scale, Revised (CDRS-R)
The CDRS is frequently used in conjunction with the K-SADS to determine the level of depressed feelings in participants across our studies. It is a measure that we frequently evaluate across time as well.
K-SADS-PL (Kiddie-Sads-Present and Lifetime Version)
The K-SADS is our primary clinical measure. Clinically trained members of the RAD Lab administer the K-SADS during your first study visit. This assessment involves answering a number of questions about your medical and psychiatric symptoms and history. Both the participant and a parent/guardian (if the participant is under 18) will complete a copy of the assessment separately.
