Objective: The clinical global impression-improvement scale (CGI-I) is used to monitor treatment outcome in mental disorders. To better understand the properties of the CGI-I scale in social anxiety disorder, effects sizes from the CGI-I scale were compared to comparably calculated effect sizes from other rating scales obtained from double-blind, placebo-controlled trials of selective-serotonin reuptake inhibitors in social anxiety disorder. From peer-reviewed, double-blind, placebo-controlled studies evaluating selective serotonin reuptake inhibitors in social anxiety disorder, we extracted CGI-I data and scores from other assessment scales of severity and function. Using calculations that enabled direct comparisons, effect sizes for the binarily reported CGI-I …
