The short form of the Depression Inventory correlated strongly with the long form (r=0.89-0.97) and clinicians' ratings (r=0.55-0.67), serving as a satisfactory substitute for screening.

May support efficient outpatient screening; leaves open prospective validation against clinical outcomes.
Beck et al. (1974) conducted a cross-sectional in Depression (n=431). Short form of the Depression Inventory vs. Long form of the Depression Inventory and clinicians' ratings was evaluated on Correlation between test scores and clinicians' ratings, and between short and long forms (r = 0.89 to 0.97 (vs long form)). The short form of the Depression Inventory correlated strongly with the long form (r=0.89-0.97) and clinicians' ratings (r=0.55-0.67), serving as a satisfactory substitute for screening.
