The DISSA: an abridged self-administered version of the DIS. Approach by episode.
The Epidemiological Catchment Area (ECA) program is a major step in psychiatric epidemiology because it uses a structured interview: the Diagnostic Interview Schedule (DIS). This gives psychiatric diagnoses in different diagnostic systems and can be administered by lay interviewers. However many surveys on health-related topics cannot give the time needed to administer the DIS and train the personnel to use such a complex schedule as the DIS. The DISSA is a self-administered abridged form of the DIS and represents an effort to produce a short and simple instrument for three types of diagnoses: major depressive disorder, all anxiety disorders (generalized anxiety, phobias, panic) and alcohol disorders. In this paper we describe the DISSA and give preliminary evidence about its efficiency. This will be done by comparing DISSA results with clinicians judgments, the DIS and a checklist derived from HSC. The DISSA functions in a manner similar to its parent instrument but achieves this in a shorter and less costly mode. Actually the approach by episode used for assessing depression seems to work better than the DIS. Comparisons with the checklist show a clear superiority of the DISSA for depression, alcohol and anxiety disorders but not for generalized anxiety.
