The Dysthymia 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 2 years. The Dysthymia instrument differed from the Depression instrument in that the Dysthymia instrument asked about feelings of sadness or depression most of the time whereas the Depression instrument focused on feelings of sadness or depression for two weeks or more in a row.

WAVE 2: The Dysthymia survey (PDF 3.1MB) was administered to subjects' primary caregivers for Cohorts 0 to 15.
