Structured Clinical Interview for Sleep Disorders (SCISD)

SCISD and SCISD-R

The Structured Clinical Interview for DSM-5 Sleep Disorders (SCISD) and the revised version (SCISD-R) are semi-structured interviews for clinicians to assess the most common sleep disorders.

Abstract:

Study Objectives: To develop and demonstrate interrater reliability for a Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) Sleep Disorders (SCISD).

Methods: The SCISD was designed to be a brief, reliable, and valid interview assessment of adult sleep disorders as defined by the DSM-5. A sample of 106 postdeployment active-duty military members seeking cognitive behavioral therapy for insomnia in a randomized clinical trial were assessed with the SCISD prior to treatment to determine eligibility. Audio recordings of these interviews were double-scored for interrater reliability.

Results: TThe interview is 8 pages long, includes 20 to 51 questions, and takes 10 to 20 minutes to administer. Of the nine major disorders included in the SCISD, six had prevalence rates high enough (ie, n ≥ 5) to include in analyses. Cohen kappa coefficient (κ) was used to assess interrater reliability for insomnia, hypersomnolence, obstructive sleep apnea hypopnea (OSAH), circadian rhythm sleep-wake, nightmare, and restless legs syndrome disorders. There was excellent interrater reliability for insomnia (1.0) and restless legs syndrome (0.83); very good reliability for nightmare disorder (0.78) and OSAH (0.73); and good reliability for hypersomnolence (0.50) and circadian rhythm sleep-wake disorders (0.50).

Conclusions: The SCISD is a brief, structured clinical interview that is easy for clinicians to learn and use. The SCISD showed moderate to excellent interrater reliability for six of the major sleep disorders in the DSM-5 among active duty military seeking cognitive behavioral therapy for insomnia in a randomized clinical trial. Replication and extension studies are needed.

Please note that the SCISD, in its current form, was based on DSM5.org criteria released in 2010 (website no longer accessible), when our two studies requiring a diagnostic interview began. The actual DSM-5 was not published until 2013, once reliability data was already collected for the above study. Between the originally proposed criteria in 2010 and the final publication in 2013, a few additional disorder specific criteria were added for disorders such as hypersomnia. In addition, most of the other disorders had standard criteria added assessing clinically significant impairment. Finally, almost all the sleep disorders had language attempting to assess primary or secondary nature of the disorder (e.g., "not better explained"/"not attributable to" other sleep-wake disorders, substance, mental and medical disorders), despite considerable disagreement in the field about how reliable and valid assessments of these may be and a preference for the "comorbid" diagnosis. That said, we have developed the revised version of the SCISD (the SCISD-R, available above), which we hope to validate within academic sleep disorders centers.

SCISD-R

The revised version of the SCISD is based on DSM-5 criteria for sleep disorders. Please note that the SCISD-R has not yet been validated, although it is closely based on the SCISD. We believe this is the preferred version.
