The Spanish Diagnostic Interview Schedule. Reliability and comparison with clinical diagnoses.

The National Institute of Mental Health Diagnostic Interview Schedule (DIS) was translated into Spanish. The reliability of the Spanish instrument, its equivalence to the English version, and its agreement with clinical diagnoses were examined in a study of 90 bilingual (English-and Spanish-speaking) and 61 monolingual (Spanish-speaking only) patients from a community mental health center. The study design involved two independent DIS administrations and one independent clinical evaluation of each subject.
