The Interview - Dysthymia Module Example

The CIDI v2.1 is a fully structured interview that has questions that cover each and every criterion in DSM-IV and ICD-10. Below is the Dysthymia module. E34 and 34A asks for the key criterion and skips people out if they say no, for then they cannot meet crtieria for the disorder. If they say yes then they are asked a series of questions (PRB12345) to ensure that the depression was not always due to physical illness or injury or to drugs or alcohol. The probe flow chart is complex and this is why an interviewer needs training or needs to use the CIDI-Auto in which the computer takes care of the logic.

The diagnostic criteria deemed to be satisfied by a positive response are in the left margin. In E45, 4B6 means DSM-IV criterion B, part 6 and 10C7 means ICD-10, criterion C, part 7. E53 ask the dates of onset and recency. E54 is not part of dysthymia but addresses an exclusion criteria for GAD. Most diagnoses are covered in a similar fashion.

CIDI v3.0 incoporates the probe flow chart into the questions.
