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.
Cross-Sectional (n=431)
Effect estimate: r = 0.89 to 0.97 (vs long form)
Summary. –-The short form of the Depression Inventory was administered to a variety of patient samples totalling 431 S s. The correlation between test scores and clinicians’ ratings ranged from .55 for a hospitalized depressed sample to .67 for S s in a general medical outpatient practice. The correlation between test scores on the two forms ranged from .89 to .97. When speed of administration is an important factor, the short form can serve as a satisfactory substitute for the long form of the inventory and is especially suited for screening medical outpatients for the presence of depression.
Beck et al. (Sat,) 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.
