    Daytime sleepiness was assessed using the Epworth Sleepiness Scale, showing significant increases at weeks 2, 4, and 6.

    Factors influencing daytime sleepiness included sex, medication use, snoring, and baseline sleepiness levels.

    Increased daytime sleepiness at week 2 predicted greater reductions in Pittsburgh Sleep Quality Index scores at later follow-ups.

    The findings suggest that early increased sleepiness during dCBT-I may serve as a predictor of treatment efficacy.
