The measurement properties of the Adolescent Depression Rating Scale (ADRS) and the Quick Inventory of Depressive Symptomatology (QIDS) in youth with major depressive disorder (MDD): a systematic review protocol

The objectives of this review are to determine if the ADRS and the QIDS have sufficient measurement properties according to the COSMIN guidelines, to evaluate the quality of this evidence, and to determine whether these OMIs meet at least minimum COSMIN criteria to support their use in youth with MDD and consideration for inclusion in a COS for this population (i.e., sufficient content validity (any level) AND at least low quality evidence for sufficient internal consistency).
