In the SleepCARE RCT of CBT-I and BLT administered for 6 weeks to women receiving chemotherapy for breast cancer, CBT-I improved insomnia but not fatigue compared with SHE or BLT. BLT did not produce greater improvements in fatigue or insomnia symptoms compared with non-BLT treatment. The study findings indicate that brief CBT-I, but not BLT, may reduce insomnia symptoms among women receiving chemotherapy for breast cancer.
