Validation of a Depression Screening Measure for Stroke Inpatients.

The Stroke Inpatient Depression Inventory (SIDI) was developed and tested on 50 stroke inpatients on a rehabilitation unit. The format and content of the SIDI questions were intended to improve on the limited validity of the Center for Epidemiological Studies-Depression Scale (CES-D) and other measures of depression with stroke inpatients. The validity of the SIDI was supported by higher correlations with a psychiatrist's rating of depression level (r = 0.70), SADS-C score (r = 0.68), and Hamilton Rating Scale for Depression score (r = 0.78) compared with the CES-D. Also, the SIDI was more accurate than the CES-D in correct classification of patients with regard to diagnosis of depression (86% vs. 76% correct).
