[A comparison study of cognitive-behavioral therapy alone versus combination with tapered hypnotic agents in patients with chronic insomnia].

Both cognitive-behavioral therapy for insomnia (CBT-i) and a combination with tapered hypnotic agents significantly reduced sleep disturbance scores after 8 weeks.

• In the CBT-i group, total scores for sleep quality, depression, and anxiety decreased significantly, with PSQI scores dropping from 12.9 to 4.7.
• The combination group also showed significant reductions in sleep quality, depression, and anxiety scores, with PSQI scores decreasing from 13.9 to 5.8.
• Subjective sleep quality, sleep onset latency, sleep efficiency, and sleep disturbance in the combination group improved significantly by weeks 4 and 8.
• Total sleep time and daytime dysfunction in the combination group decreased significantly by week 8.
• CBT-i was more effective than the combination in improving sleep onset latency and sleep efficiency.
