The problem of TDI's diagnostic accuracy, as measured by interrater reliability, is almost totally ignored by clinical and academic psychiatry. Only two were about the real-time use of TDI as a global process. But clinicians continue to use TDI alone, in spite of its proven limitations. CADI was first presented at the APA's annual meeting in 1996. CADI modifies both data collection and data processing.
Data collection is done with a protocol.
The use of protocols during TDI is nearly universal. CADI protocol comes in two forms, printed and computerized. All protocol items are number-coded so that the clinician or an assistant can enter the data into the computer. Each page of the protocol is displayed on the computer screen, one item at a time. Sample questions are provided alongside each item to help beginning clinicians avoid leading or close-ended questions.
