Responses of 100 psychiatric patients on a new self-report measure—the Popoff Index of Depression—and the MMPI are compared. The index appears to measure subjective aspects of depression and correctly categorizes a large percentage of depressed patients. It does not measure the low energy level frequently seen in depressed patients nor does it differentiate depression from anxiety. Age and sex differences suggest the need for a change in the cut-off score recommended in the original article. The value of the covert depression subscale of the index remains questionable.
