SCID-5 Info

WHAT IS THE SCID-5?

The Structured Clinical Interview for DSM-5 (SCID-5) is a semi-structured interview guide for making the major DSM-5 diagnoses (formerly diagnosed on Axis I). It is administered by a clinician or trained mental health professional who is familiar with the DSM-5 classification and diagnostic criteria. The interview subjects may be either psychiatric or general medical patients—or individuals who do not identify themselves as patients, such as participants in a community survey of mental illness or family members of psychiatric patients. There are three different versions of the SCID-5 that can be used for diagnosing the major DSM-5 diagnoses: 

  • Research Version (SCID-5-RV)
  • Clinician Version (SCID-5-CV)
  • Clinical Trials Version (SCID-5-CT)

A fourth SCID-5 version, the SCID-5-PD, is also available to assess the ten DSM-5 Personality Disorders (formerly diagnosed on Axis II).

WHAT ARE THE DIFFERENCES BETWEEN THE VARIOUS VERSIONS OF THE SCID-5?

SCID-5-RV (Research Version):

The Research Version (SCID-5-RV) is the most comprehensive SCID version and contains more disorders than the Clinician Version or the Clinical Trials Version.  It also includes the DSM-5 subtypes, severity, and course specifiers for most of the disorders. 

The SCID-5-RV is available in a standard “core” configuration that includes those disorders most researchers are likely to assess routinely for most studies (click here for the list of disorders covered in the core SCID-5-RV). The SCID-5-RV is also available in an “enhanced” configuration that includes the assessment of a number of optional disorders (click here for the list of disorders covered in the enhanced SCID-5-RV). 

To facilitate customization, the SCID-5-RV is not published as a bound volume, but rather distributed by the American Psychiatric Association Publishing (APA) as either unmodifiable PDF files or modifiable Microsoft Word documents. The Microsoft Word version allows SCID-5 customization to meet the needs of a particular study. For instance, the interview flow can be altered so that disorders or unneeded elements such as specifiers can be removed.  Alternatively, the order that diagnoses are assessed can be modified, or additional elements not included within the SCID-5-RV, such as severity rating scales may be incorporated.  

SCID-5-CV (Clinician Version):

The Clinician Version (SCID-5-CV) is published as a bound booklet by APA and is an abridged and reformatted version of the SCID-5-RV that covers those diagnoses most commonly seen in clinical settings (click here for the list of disorders covered in the SCID-5-CV). Despite the “clinician” designation, the SCID-5-CV can be used in research settings as long as the disorders of particular interest to the researcher are among those included in the SCID-CV.

The SCID-5-CV differs from the SCID-5-RV in several ways (Click here for a summary of differences between the SCID-5-CV and SCID-5-RV).  First, the specifiers included in the SCID-5-CV are limited to those that have an impact on the diagnostic coding.  For example, only the severity, psychosis, and remission specifiers for Bipolar Disorder and Major Depressive Disorder are included in the SCID-5-CV since they affect the choice of diagnostic code.  Second, the full criteria sets for a number of disorders (e.g., Anorexia Nervosa, Hoarding Disorder, etc.) included in the SCID-5-RV do not appear in the SCID-5-CV.  Screening questions for those disorders have been provided instead. 

If a subject answers screening questions in the affirmative, the clinician must follow up with an unstructured clinical assessment of the diagnostic requirements for that disorder.  (To facilitate this process, the SCID-5-CV includes the DSM-5 page numbers for the corresponding criteria sets, and the User’s Guide reprints the DSM-5 criteria sets for the screened disorders)  Finally, although most disorders in the SCID-5-RV are assessed for both current and lifetime, the SCID-5-CV focuses largely on whether criteria are currently met since the current clinical status of a disorder is most relevant for treatment decisions.  The only disorders in the SCID-5-CV that also include a lifetime assessment are: Bipolar I and II Disorder, Major Depressive Disorder, Panic Disorder, PTSD, Schizophrenia, and the other psychotic disorders.

SCID-5-CT (Clinical Trials Version): 

The Clinical Trials Version (SCID-5-CT) is an adaptation of the SCID-5-RV that has been reformatted, streamlined, and optimized for use in clinical trials that incorporate typical inclusion and exclusion criteria. There are two options available for those interested in using the SCID-5-CT.

The first option is the contents of the SCID-5-CT can be uniquely tailored to conform to the specific diagnostic inclusion and exclusion criteria of a particular protocol. There is an additional customization fee for the SCID-5-CT to be modified to the clinical trials study criteria.

Alternatively, there several SCID-5-CT templates available for use in clinical trials which can be customized by a user. If, however, the template does not include evaluation of a particular disorder of interest, in either the inclusion or exclusion criteria, it is recommended that the user select the customized option so that the additional criteria can be incorporated in the SCID-5-CT.

The SCID-5-CT templates available for use in clinical trials include: Schizophrenia, Schizophrenia/Schizophreniform/ Schizoaffective Disorder, Major Depressive Disorder, Recurrent Major Depressive Disorder, Acute Mania in Bipolar I Disorder, Bipolar Depression, and ADHD. An additional exclusionary SCID-5-CT has also been developed for studies where the SCID-5-CT is used to exclude individuals that have disorders listed in the exclusion criteria for the study (e.g., for diagnostic indications not included in the SCID-5-RV, like Major Neurocognitive Disorder). Click here for a list of the SCID-5-CT templates available for various diagnostic indications.

SCID-5-PD (Personality Disorders):

The Personality Disorders version (SCID-5-PD) is published as a separate instrument for evaluating the ten DSM-5 Personality Disorders.  A separate User’s Guide is available to provide guidance on how to assess the individual personality disorder items in the SCID-5-PD.  An optional self-report patient questionnaire for the SCID-5-PD is also available (SCID-5-SPQ).  Designed to shorten the administration time of the SCID-5-PD, the SCID-5-SPQ is a screening tool with corresponding questions that allows for any “No” responses to be bypassed in the SCID-5-PD clinical interview.  A version of the SCID-5-PD for assessing personality disorders according to the Alternative DSM-5 Model of Personality Disorder (SCID-5-AMPD) is currently in development.

ARE THERE ANY ELECTRONIC VERSIONS OF THE SCID-5 AVAILABLE? 

Yes, currently there are two electronic SCID-5 products available.

NetSCID-5

The NetSCID-5 products are the first web-based, fully computerized versions of the SCID-5 instruments. TeleSage Inc. has developed and validated an online format of the Research, Clinician, and Personality Disorders versions of the SCID-5 in consultation with the SCID-5 authors. The NetSCID-5 products are licensed by the APA. The primary difference between the NetSCID-5 products and those available through APA is that they are web-based. The NetSCID-5 products follow the text, branching and calculations of the SCID-5 instruments and offer complete data parity. Data is immediately stored on HIPAA-compliant geo-redundant databases and can be downloaded in report form or as raw data and imported into any statistical package. The NetSCID-5 products are easily accessible through any internet-connected device. A free webinar demonstration is available through TeleSage Inc.

eInterview

Sunilion Software's eInterview for SCID-5-RV is a desktop software designed to run on most Windows-based devices. The eInterview is a platform that allows users to design their own interviews or download professionally designed interviews, such as the SCID-5-RV, licensed by the APA.

WHAT KINDS OF SUBJECTS CAN BE DIAGNOSED USING THE SCID-5?

In addition to assessment of current psychiatric patients, the SCID-5 has been used to assess lifetime psychiatric diagnoses in medical patients, family members, community samples, college students, the homeless, the elderly, and in short, any adult who is able to participate in the interview.  If the SCID-5 is being administered to an individual who does not self-identify as a psychiatric patient, (e.g., medical patients or subjects in a community study), the Non-patient version of the Overview in the SCID-5-RV edition should be used.

Although the vast majority of SCID studies have been administered with adults, some investigators have successfully administered the SCID to adolescents.  A SCID-5 version specifically tailored for children and adolescents is currently under development.

While it is often not possible to administer the SCID-5 interview to subjects who have moderate or severe intellectual disability or who are otherwise too cognitively impaired to answer the questions, or to subjects who are too medically or psychiatrically ill to participate in an interview, the SCID-5 can still be used as a tool for gathering and documenting diagnostic information obtained from other sources (e.g., informants, previous records) with the application of the DSM-5 diagnostic algorithms.

CAN THE SCID-5 BE ADMINISTERED TO CHILDREN?

The language and diagnostic coverage make the SCID-5 most appropriate for use with adults (age 18 and over).  With slight modification to the wording of the questions, the SCID-5 may be administered with adolescents.  Plans are underway to develop a SCID-5 version specifically tailored for children and adolescents which will include self and parent/guardian reporting features.

ARE THERE SCID-5 LANGUAGE TRANSLATIONS AVAILABLE? 

Yes, the SCID-5 products originally developed in English have been translated by different international publishers, and many, but not all of the SCID-5 versions are available in numerous languages other than English.  Click here to access a list of the language translations alongside of the specific SCID-5 versions (SCID-5-RV, SCID-5-CV, SCID-5-PD) available.   Individuals who are interested in obtaining product or order information are to contact the selected publisher directly.  Any individuals who are interested in non-English language translations, but who only speak English, can remit their request through the APA, who will forward them to the selected publishers through their English speaking agents. 

Publishers who wish to obtain information about translating the SCID-5 products in a language not already included on the SCID-5 Translations list can click here for further information.

WHAT ARE THE QUALIFICATIONS NEEDED TO ADMINISTER THE SCID-5?

The SCID-5 is designed to be administered by mental health professionals or researchers, both of whom should have been clinically trained. There is no minimum degree requirement – the amount of clinical experience is the more crucial requirement. Ideally, SCID-5 users should have had sufficient clinical experience to be able to perform unstructured diagnostic evaluation. However, non-clinicians who have comprehensive diagnostic experience with a particular study population may be trained to administer the SCID-5. Generally additional training is required for individuals with less clinical experience.

HOW LONG DOES IT TAKE TO ADMINISTER THE SCID-5?

Since the SCID-5 administration time varies significantly based on a number of factors there is no straightforward answer to this question. These factors include the SCID-5 version, (i.e., Core versus Enhanced SCID-5-RV; SCID-5-RV versus SCID-5-CV versus SCID-5-CT), the number of disorders being assessed, the diagnostic complexity of the subject, the subject’s ability, or lack thereof to succinctly describe his or her history and symptoms, and the user’s level of familiarity and experience with DSM-5 diagnostic criteria and the SCID-5 instrument. With this in mind, the following is a range of administration times for each SCID-5 version. Subjects with complex psychopathology, diagnostic comorbidity and who are difficult to interview may take longer than the maximum administration times listed below.

SCID-5 Version

Range of administration time

SCID-5-RV Core Version

45 to 120 minutes

SCID-5-RV Enhanced Version

45 to 180 minutes

SCID-5-CV

30 to 120 minutes

SCID-5-CT

30 to 75 minutes

SCID-5-PD

30 to 120 minutes

HOW CAN I ORDER THE SCID-5?

Since the process of ordering the SCID-5 differs by version and in many instances, requires a permission fee based on type of use, e.g., non-commercial, funded research or pharmaceutical trial, below is a table to help simplify the ordering process.

WHICH SCID-5 VERSION IS BEST SUITED FOR MY PURPOSES?

When used to help guide the evaluation of non-personality disorders in clinical or forensic settings, or for training purposes (i.e., to improve diagnostic interviewing skills), the SCID-5-CV is the recommended version.

When the SCID-5 is being used for research purposes, the recommended version depends on the diagnostic needs of the research study.  The various versions of the SCID-5 differ both in terms of which diagnoses, specifiers and subtypes are covered, and the assessment time frames (i.e., current vs. lifetime).  Given its superior ease of use, if the range of diagnoses covered in the SCID-5-CV) and the absence of lifetime assessments for many of the disorders) is sufficient for a particular research study, we generally recommend the SCID-5-CV.  If not, (for instance because a non-patient version of the Overview is needed or the assessment of certain disorders of interest has been omitted from the SCID-5-CV such as Eating Disorders, then the SCID-5-RV is recommended.  Given that customizability is another primary difference between the SCID-5-RV and SCID-5-CV, if the study requirements include making modifications such as omitting certain disorders, changing the order in which disorders are assessed or altering diagnostic time frames, the SCID-5-RV is the only instrument that allows for such customization.

The SCID-5-CT is designed specifically to be used in a research context to confirm whether subjects meet the diagnostic inclusion or exclusion criteria of a protocol.  Most often the SCID-5-CT is used by pharmaceutical companies in clinical trials.  The major advantage of the SCID-5-CT over the other SCID-5 versions is that its lean, streamlined format only includes those sections that are relevant to a specific protocol, thereby reducing administration time.  Since the SCID-5-CT must be tailored to the primary inclusion criteria of the study, customization can be done by utilizing one of the available SCID-5-CT templates (which requires that the purchaser modify the SCID-5-CT to fit the actual inclusion and exclusion criteria for the study protocol) or by making a request for customization based on the inclusion/exclusion criteria of the protocol.  The SCID-5-PD is the only version of the SCID-5 which evaluates the categorical DSM-5 classification of Personality Disorders.

Another consideration is whether a computer-assisted version of the SCID-5 is desired.  If so, see the above NetSCID-5 or eInterview product information.

WHAT KIND OF TRAINING MATERIALS AND SERVICES ARE AVAILABLE FOR THE DIFFERENT
SCID-5 VERSIONS?

User’s Guide

Each version of the SCID-5 has an accompanying User’s Guide that includes general instructions on how to administer the SCID-5 as well as extensive disorder-specific guidelines.  It is essential for any user of the SCID-5 to have reviewed the User’s Guide prior to administration. 

Other SCID-5 Training Materials

The following SCID-5 training materials are currently in development. 


Planned Training Materials

 

 

Recorded Clinical Interviews and Ratings

Video recordings of SCID-5 interviews featuring diagnostic presentations.  Also includes reference ratings which can be used for training and calibration.  These are expected to be available during the fall 2017.

SCID-5-CV

On-site SCID-5 Training

On-site training consists primarily of live SCID-5 interviews with volunteer subjects to be arranged by the site facilitator and group supervision led by Dr. Michael First, lead author of the SCID-5.  Generally, there will be two full training days with three to four SCID-5 interviews scheduled per day with volunteer subjects.  The first day of training will begin with a half-day didactic presentation and an opportunity for the attendees to ask questions about the SCID-5 that have arisen during review of the User’s Guide and other training materials, which should have been reviewed by the trainees prior to the training.  The initial SCID-5 interview will be administered by Dr. First to demonstrate the SCID-5 techniques.  The cost for on-site training is variable based on specifics and is typically $2,500 per training day plus travel expenses. 

Off-site SCID-5 Supervision

Off-site supervision consists of having recorded SCID-5 interviews critically reviewed to ensure that interviewers are administering the instrument in accordance with guidelines and conventions, and making proper ratings based on the symptoms described by the interview subject.  An audio or video recording of the SCID-5 interview accompanied by a copy of the corresponding SCID-5 interview forms are reviewed by a leading SCID-5 expert who will then provide a detailed assessment documenting incorrect ratings and other deficiencies in the SCID-5 interview.  Specific suggestions to achieve increased rating reliability and accuracy will also be provided.  The cost for off-site supervision is $200 per hour, based on the on the time spent reviewing the SCID-5 interviews and preparing the summary assessment.

With exception of the SCID-5 User’s Guides, all of which are available exclusively through the APA, all other training materials and services referenced above are offered through Columbia University, Biometrics Research.  For further details visit: http://www.scid5.org/training/.
