CLINICIAN VERSION VS. RESEARCH VERSION? WHICH ONE IS RIGHT FOR ME?
The SCID-CV is an adaptation of the SCID that is intended to introduce the benefits of structured interviewing into clinical settings. It is important for researchers to recognize that, despite its title, the SCID-CV may also be quite appropriate for use in a research setting, depending upon the needs of the investigator. The biggest advantages of the research version are that it is much easier to modify for a particular study and its coverage is more complete (i.e., it includes the full diagnostic criteria for the disorders and subtypes). If the possibility of modifying the SCID is not important to you, or if you are not interested in the disorders or subtypes covered by the full SCID, the SCID-CV may be a more appropriate instrument for your needs. In general, for studies in which the SCID is being used simply to describe the diagnostic characteristics of a sample, the SCID-CV may be the instrument of choice. One caveat: researchers with extensive experience using the Research Version of the SCID may find the SCID-CV format (i.e., having a separate Administration booklet and score sheet) difficult to get used to and therefore may prefer to continue using the Research Version of the SCID.
DIFFERENCES BETWEEN SCID-CV AND SCID-I (Research Version):
1. Overall Format: One of the biggest differences between the Research Version and the Clinician Version is that the Research Version is a single interview booklet that includes both the questions and the scoring. It is distributed by Biometrics Research as a single-sided, unbound master that is intended to be copied by the researcher for use in a particular study. This format also facilitates modifying the SCID in order to suit the needs of a particular study. Single pages or entire modules can be deleted if they are not relevant to the needs of a study. Rating scales used in a study can be inserted into the appropriate sections of the SCID as well.
The SCID-CV, on the other hand, is published in two parts: a spiral-bound re-usable administration booklet (with color-coded tabs) and a separate one-time-use score sheet that can serve as a record of a patient’s diagnostic status and can be inserted into the chart. Although the interviewer is free to skip over sections that are not relevant to the evaluation or alternatively to administer only those sections that are needed to confirm a diagnosis, the format of the SCID-CV makes it difficult to customize for a particular setting.
2. Coverage: The SCID-I Research Version and the SCID-CV cover mostly the same disorders, although not at the same level of detail (see below). The following disorders are included in the Research Version of the SCID-I but are not in the SCID-CV in any form: Acute Stress Disorder, Minor Depressive Disorder (DSM-IV Appendix category), Mixed Anxiety Depressive Disorder (Appendix category), and Binge Eating Disorder (Appendix category).
3. Subtypes and Specifiers: In order to make the SCID-CV assessment as efficient as possible, it has been streamlined so as to assess only those subtypes and specifiers that are required as part of the DSM-IV diagnostic codes (e.g., since severity of current mood episode is required for the fifth digit coding of Major Depressive Disorder and Bipolar I Disorder, these are assessed in the SCID-CV). On the other hand, the SCID-I Research Version has been designed to be as comprehensive as possible--all of the subtypes and specifiers that are potentially applicable to the covered disorders are included. Table 1 (below) contains those specifiers that are included only in the Research Version of the SCID-I.
4. Abridged Assessments of Some Disorders: As part of the streamlining of the SCID-CV, we decided to have two types of assessments: a standard assessment in which an interview question is supplied for each of the diagnostic criteria for the disorder (as it is in the Research Version); and a "summarized" assessment in which only a single interview question is supplied for a disorder. Furthermore, the full criteria sets for these summarized disorders are not included; instead, a condensed description is provided with a reference to the page in the DSM-IV where the complete criteria sets are contained. In most cases, this single question corresponds to the first question for that disorder in the Research Version of the SCID. The summarized assessments are for those disorders that we have judged to be of interest primarily in specialized settings. Table 2 (below) contains a list of those disorders that are covered in the SCID-CV in a summarized format.
5. Different Assessment Formats: The assessment of a number of the disorders in the SCID-CV has been simplified as compared to the Research Version.
6. Distribution: The SCID-I Research Version is available by visiting the Order Info tab of this web site. The Clinician Version of the SCID for DSM-IV is CV is published by the American Psychiatric Publishing, Inc. (APPI). To order the SCID-CV visit www.appi.org
