Which statement describes Chronic Insomnia criteria?

• A. The sleep disturbance occurs fewer than 3 times per week.
• B. The sleep disturbance and associated daytime symptoms occur at least 3 times per week.
• C. The reported sleep-wake complaints can be explained by inadequate opportunity for sleep.
• D. The sleep disturbance is not associated with daytime impairment.

Answer: (B)

Chronic insomnia is diagnosed when there is a recurrent sleep disturbance that is accompanied by daytime impairment. The statement that sleep disturbance and associated daytime symptoms occur at least three times per week fits this pattern because it ties the nighttime problem to meaningful daytime consequences at a clinically relevant frequency. This reflects the core idea that insomnia involves both persistent sleep trouble and daytime impact, not just occasional sleep issues.

The other options don’t fit as well: having sleep problems fewer than three times per week would not meet the frequency threshold; explaining the sleep issue by inadequate opportunity for sleep points to insufficient sleep opportunity rather than an insomnia disorder; and stating no daytime impairment would miss the key feature that makes insomnia clinically significant.
