Depression

The Depression module of the Composite International Diagnostic Interview (UM-CIDI) short form was adapted and used with the primary caregiver (PC) of subjects to obtain information about depressive symptoms experienced by the PC during the past year. The Depression instrument differed from the Dysthymia instrument in that the Depression instrument asked about feelings of sadness or depression for two weeks or more in a row whereas the Dysthymia instrument focused on feelings of sadness or depression most of the time.
