| Annotation | This article reviews the history of Clinical Global Impressions of Change (CGIC) instruments, their use and limitations in clinical trials of Alzheimer's disease (AD), and the development of the US National Institute of Aging's (NIA) Alzheimer's Disease Co-operative Study - Clinical Global Impression of Change Scale (ADCS-CGIC). Originally, CGICs were simple and unstructured instruments that asked a clinician to rate change over the duration of a clinical trial. The method, however, failed to consistently detect treatment effects, leading to the development of more structured and subsequently validated approaches, such as the Clinician Interview-Based Impression Scale (CIBI) and the ADCS-CGIC. Both are currently used in clinical trials. The implications and importance of choosing an appropriate global rating are discussed. (RH). |
