Manuscript Pre-Print_Stallwood et al., 2021 CDRS-R adolescents
The Children’s Depression Rating Scale-Revised (CDRS-R) is the most commonly used method to measure depression in treatment studies of teens with depression, but itis unknown whether the CDRS-R is appropriate for the purpose of measuring depression inadolescents. This study aimed to identify all existing evidence of the key measurement propertiesof the CDRS-R (for example, how well the scale measures what it is supposed to measure) in teens with depression, and to evaluate these properties using a well-establishedmethod developed by the COSMIN Initiative (https://www.cosmin.nl/). The study concludes thatit is unclear whether the CDRS-R can appropriately measure depression symptom severity in treatment studies of teens with depression based on current available evidence. It is important that the best methods are used to measure outcomes to ensure that results from clinical researchstudies in teens with depression are meaningful and useful to relevant stakeholders, including patients, caregivers, health care providers, researchers, and policymakers.
