Structured Clinical Interview for DSM-IV
Encyclopedia
The Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) is a diagnostic exam used to determine DSM-IV Axis I disorders (major mental disorders) and Axis II disorders (personality disorder
s). There are at least 700 published studies in which the SCID was the diagnostic instrument used. Major parts of the SCID have been translated into other languages, including Danish
, French
, German
, Greek
, Hebrew, Italian
, Portuguese
, Spanish
, Swedish
, Turkish
, and Zulu
.
An Axis I SCID assessment with a psychiatric patient usually takes between 1 and 2 hours, depending on the complexity of the past psychiatric history and the subject's ability to clearly describe episodes of current and past symptoms. A SCID with a non-psychiatric patient takes 1/2 hour to 1-1/2 hours. (See editions below.) A SCID-II personality assessment takes about 1/2 to 1 hour.
The instrument was designed to be administered by a clinician or trained mental health professional, for example a psychologist
or social worker. Ideally, this would be someone who has had experience performing unstructured, open-ended question
, diagnostic evaluations. However, for the purposes of some research studies, non-clinician research assistants, who have extensive experience with the study population in question, and who have demonstrated competence, have been trained to use the SCID. The less clinical experience and specific education the potential interviewer has had, the more training is required.
The SCID-II for DSM-IV comes in a single edition.
The reliability
and validity
of the SCID for DSM-III-R has been reported in several published studies. With regard to reliability, the range in reliability is enormous, depending on the type of the sample and research methodology (i.e., joint vs. test-retest, multi-site vs. single site with raters who have worked together, etc.)

, especially in research settings. This interview takes about 30 minutes to 1.5 hours, depending on individual's experiences. The SCID-D has been translated into Dutch
and used in the Netherlands.
