Structured clinical interviews for DSM-IV (SCID; First, Spitzer, Gibbon, & Williams, 1994),
assessment of observer-rated depression with the HRSD, and the distribution of self-report
questionnaires (DEQ, IIP, BDI-II) took place at intake before start of treatment for the outpatient
sample and within the first week of treatment for the inpatient sample. In both samples,
master’s- or doctoral-level psychologists conducted standardized diagnostic interviews. Part of
the inpatient sample answered the BDI-I instead of the BDI-II. The original authors revised the
BDI-I to better reflect DSM-IV criteria for major depression
