Description
The Structured Clinical Interview for DSM-IV Axis I Disorders
(SCID-I) is a semistuctured interview for making the major DSM-IV
Axis I diagnoses. The instrument is designed to be administered by
a clinician or trained mental health professional. Ideally, this
will be someone who has had experience performing unstructured
diagnostic evaluations. However, for the purposes of some research
studies, non-clinician research assistants who have extensive
experience with the study population in question have been trained
to use the SCID. The less clinical experience the potential
interviewer has had, the more training is required.
The SCID is broken down into separate modules corresponding to
categories of diagnoses. Most sections begin with an entry question
that would allow the interviewer to "skip" the associated questions
if not met. For all diagnoses symptoms are coded as present,
subthreshold, or absent. A diagnosis of PTSD is made following the
PTSD diagnostic algorithm.
Sample Item
Entry question
How did you react when (trauma) happened? (were you very afraid
or did you feel terrified or helpless?)
1=absent or false
2=subthreshold
3=threshold or true
Question B1
Now I'd like to ask you a few questions about specific ways that
it may have affected you. For example: did you think about (trauma)
when you didn't want to or did thoughts about (trauma) come to you
suddenly when you didn't want them to?
1=absent or false
2=subthreshold
3=threshold or true
Versions
The SCID-1 is a semistuctured interview for making the major
DSM-IV Axis I diagnoses (e.g., PTSD). The SCID-II is a
semi-structured interview for making DSM-IV Axis II (Personality
Disorder) diagnoses.The Clinician Version is a streamlined version
of the SCID-I (for Axis I Disorders) available from American
Psychiatric Press, Inc. One significant difference is in
formatting: the SCID-CV is published in two parts--a reusable
Administration Booklet (with color-coded tabs) and
one-time-use-only scoresheets. The Research Version is available
only as a single-sided master.
The SCID-I/P (Patient Edition) is the standard SCID and is
designed for use with subjects who are identified as psychiatric
patients. For settings in which psychotic disorders are expected to
be rare (e.g., an outpatient anxiety clinic) or for studies in
which patients with psychotic disorders are being screened out, an
abridged edition of the SCID-I/P (SCID-I/P W/ PSYCHOTIC SCREEN) is
available. This edition replaces the standard Psychotic Modules
(i.e., Modules B and C) with a combined B/C module that includes
only screening questions about psychotic symptoms. In addition, the
SCID-I/P (W/PSYCHOTIC SCREEN) has an abridged summary score sheet
that does not include psychotic disorders. The SCID-I/NP
(Non-patient Edition) is for use in studies in which the subjects
are not identified as psychiatric patients (e.g., community
surveys, family studies, research in primary care). The diagnostic
modules of the SCID-I/NP are the same as those of the SCID-I/P
(W/PSYCHOTIC SCREEN); the only difference in the two versions is in
the Overview section. In the SCID-I/NP there is no assumption of a
chief complaint, and other questions are used to inquire about a
history of psychopathology.
