The Structured Clinical Interview for DSM-5 (SCID-5) is a semi-structured interview guide for making DSM-5 diagnoses. It is administered by a clinician or trained mental health professional that is familiar with the DSM-5 classification and diagnostic criteria.
The SCID-5 can be used in a variety of ways:
- To ensure that the major DSM-5 diagnoses are systematically evaluated. For example, the SCID can be used in clinical intake procedures or in comprehensive forensic diagnostic evaluation.
- To select a study population. For example, in a study of the effectiveness of a treatment for depression, the SCID-5 can be used to ensure that all of the study subjects have symptoms that meet the DSM-5 criteria for Major Depressive Disorder and that all of the subjects with a history of any Substance Use Disorder in the past 12 months are excluded.
- To characterize a study population in terms of current and previous psychiatric diagnoses. For example, the diagnostic data that have been obtained using the SCID interview can be utilized by researchers, practitioners, policy makers, and the general public that are interested in prevalence and incidence estimates of psychiatric disorders among certain populations.
- To improve interviewing skills of students in the mental health professions, including psychiatry, psychology, social work, and psychiatric nursing. For example, the SCID can provide trainees with a repertoire of useful questions to elicit information from a patient that will be the basis for making judgments about the diagnostic criteria. Through repeated administrations of the SCID, students will become familiar with the DSM-5 criteria and at the same time will incorporate useful questions into their own interviewing repertoire.
SCID-5-CV (Clinician Version)
The Clinician Version (SCID-5-CV) is published as a bound booklet and is an abridged and reformatted version of the SCID-5-RV for use by clinicians. It covers the diagnoses most commonly seen in clinical settings. Please see the Diagnostic Coverage of SCID-5-CV and SCID-5-RV to determine which SCID-5-RV disorders are not included 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-5-CV. Screening questions are provided for the diagnoses that are included in their entirety in the SCID-5-RV but that have been left out of the SCID-5-CV. If the patient answers any of these screening questions in the affirmative, the clinician needs to follow up with an unstructured clinical assessment of the diagnostic requirements for the screened disorders.
Besides diagnostic coverage, the SCID-5-CV differs from the SCID-5-RV in other ways. The specifiers included in the SCID-5-CV are limited to those that have an impact on the diagnostic coding. Thus, only the severity, psychosis, and remission specifiers for Bipolar Disorder and Major Depressive Disorder are included in the SCID-5-CV. Similarly, the Attention-Deficit/Hyperactivity Disorder presentation types (i.e., predominantly inattentive, predominantly hyperactive/impulsive, and combined) are included because they are also required to determine the diagnostic code.
Moreover, although most of the disorders in the SCID-5-RV are assessed for both current and lifetime, the SCID-5-CV focuses largely on whether the 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 Major Depressive Disorder, Bipolar I and II Disorders, Schizophrenia and the other psychotic disorders, Panic Disorder, and PTSD.
SCID-5-PD (Personality Disorders)
The SCID-5-PD is the updated version of the former Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II) to assess the 10 DSM-5 Personality Disorders across Clusters A, B, and C as well as Other Specified Personality Disorder. Designed to build rapport, the SCID-5-PD can be used to make personality disorder diagnoses, either categorically (present or absent) or dimensionally. The SCID-5-PD name reflects the elimination of the multiaxial system in DSM-5. Although the DSM-IV Personality Disorder criteria are unchanged in DSM-5, the SCID-5-PD interview questions have been thoroughly reviewed and revised to optimally capture the construct embodied in the diagnostic criteria.
In addition, a dimensional scoring component has been added to the SCID-5-PD. The basic structure of the SCID-5-PD is similar to the other SCID-5 interviews (such as the Research Version, SCID-5-RV, and the Clinician Version, SCID-5-CV) that cover non–personality DSM-5 disorders. Features include the following:
- Questions assessing the DSM-5 criteria for each of the 10 personality disorders: Avoidant Personality Disorder, Dependent Personality Disorder, Obsessive-Compulsive Personality Disorder, Paranoid Personality Disorder, Schizotypal Personality Disorder, Schizoid Personality Disorder, Histrionic Personality Disorder, Narcissistic Personality Disorder, and Antisocial Personality Disorder.
- A User's Guide for the SCID-5-PD containing essential guidance for use of the SCID-5-PD, including an appendix of a completed SCID-5-PD and SCID-5-SPQ for a sample patient.
- An optional SCID-5-SPQ that serves as a brief, 20-minute self-report screening tool to reduce the time of the SCID-5-PD clinical interview. The SCID-5-SPQ requires an eighth grade or higher reading level (as determined by the Flesch-Kincaid formula). Its 106 questions correspond directly to each first question in the full SCID-5-PD.
