Reliability of the Structured Clinical Interview for DSM-5 Sleep Disorders Module

Area of Science:

• Sleep Medicine
• Psychiatry
• Clinical Psychology

Background:

• Accurate diagnosis of sleep disorders is crucial for effective treatment.
• The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) provides diagnostic criteria for sleep disorders.
• A reliable clinical interview tool is needed to assess these disorders efficiently.

Purpose of the Study:

• To develop and evaluate the interrater reliability of the Structured Clinical Interview for DSM-5 Sleep Disorders (SCISD).
• To assess the SCISD's utility in a clinical population of active-duty military members.

Main Methods:

• The SCISD was administered to 106 active-duty military members.
• Audio recordings of the interviews were double-scored by independent raters.
• Interrater reliability was assessed using Cohen kappa coefficients (κ) for six sleep disorders.

Main Results:

• Excellent reliability was found for insomnia (κ=1.0) and restless legs syndrome (κ=0.83).
• Very good reliability was observed for nightmare disorder (κ=0.78) and obstructive sleep apnea hypopnea (κ=0.73).
• Good reliability was noted for hypersomnolence (κ=0.50) and circadian rhythm sleep-wake disorders (κ=0.50).

Conclusions:

• The SCISD is a brief, user-friendly interview with demonstrated moderate to excellent interrater reliability for major DSM-5 sleep disorders.
• The SCISD is a valuable tool for clinicians assessing sleep disorders in military populations.
• Further research is recommended to replicate and extend these findings.
