Study compared the efficacy of the Ilfeld Psychiatric Symptom Index to the Zung Self-Rating Depression Scale in identifying depressive symptoms in people with spinal cord injury (SCI). Thirty-nine subjects SCI and 20 age-matched control subjects completed both screening measures and total scores for both scales were analyzed. Results showed a low level of agreement between scales. The Ilfeld classified 79 percent of the SCI group and 75 percent of the controls as depressed, whereas 8 percent of the SCI group and none of the controls were depressed according to the Zung scale. The Ilfeld screens for a broad range of symptoms; however, the somatic symptom items may have caused an overestimation of psychologic symptoms in both the SCI and control groups.
