The self-report Dissociative Disorders Interview Schedule: A preliminary report

A self-report version of the Dissociative Disorders Interview Schedule (SR-DDIS) was administered to 100 inpatients in a hospital-based trauma program. All participants had previously completed the interviewer-administered version of the DDIS. When we compared the overall results on the DDIS and SR-DDIS for the 100 inpatients, the findings were very consistent for both symptom clusters and Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), diagnoses. The agreement rate between the 2 versions for DSM-5 diagnoses was fair to substantial using Cohen's kappa, with agreement being substantial for 4 out of the 7 diagnoses made by the DDIS. It appears likely that the SR-DDIS can be used instead of the DDIS, at least in clinical populations, with no clinically or conceptually significant differences between the results obtained with the 2 versions.
