Hm. Chochinov et al., ARE YOU DEPRESSED - SCREENING FOR DEPRESSION IN THE TERMINALLY ILL, The American journal of psychiatry, 154(5), 1997, pp. 674-676
Objective: This study compared the performance of four brief screening
measures for depression in a group of terminally ill patients. The me
thods included 1) a single-item interview assessing depressed mood, 2)
a two-item interview assessing depressed mood and loss of interest in
activities, 3) a visual analog scale for depressed mood, and 4) the B
eck Depression Inventory-Short Form. Method: Semistructured diagnostic
interviews for depression were administered to 197 patients receiving
palliative care for advanced cancer. The interview diagnoses served a
s the standard against which the screening performance of the four bri
ef screening methods was assessed. Results: Single-item interview scre
ening correctly identified the eventual diagnostic outcome of every pa
tient, substantially outperforming the questionnaire and visual analog
measures. Conclusions: Brief screening measures for depression are im
portant clinical tools for terminally ill patients. For diagnostic pur
poses, however, they do not approach the validity of a single-item tha
t asks, in effect, ''Are you depressed?''
