Experimentální: dCBT-I + dCI group
Potential subjects will receive therapist-guided digital cognitive behavioral therapy for insomnia and digital circadian intervention.
|
For the combined dCBT-I + dCI program, additional circadian intervention will be included to support entrainment of the biological clock. These components include circadian education, strategies to gradually advance circadian phase, advice on morning sunlight exposure, and components of social rhythm therapy to establish a consistent daily sleep routine (e.g., consistent meal times and exercise). The digital intervention will be implemented through a therapist-guided using motivational interviewing approach. Participants will be motivated to advance their sleep schedule by following fixed daytime activities using motivational interviewing techniques to support their autonomy and self-efficacy in making behavioral changes |
|
Aktivní komparátor: dCBT-I group
Potential subjects will receive therapist-guided digital cognitive behavioral therapy for insomnia.
|
Digital CBT-I has been developed by our group based on a well-established framework that includes sleep education, behavioral strategies such as stimulus control and sleep restriction, constructive worry strategies, cognitive restructuring, relaxation training and sleep hygiene education.
For the dCBT-I alone group, therapists will primarily review participants' sleep schedule, setting sleep restriction window, and problem-solving efforts.
|
|
Aktivní komparátor: d-HE group
Potential subjects will receive digital health education.
|
Participants in the control group will be app-based general health education with an equivalent dosage as the two intervention groups.
To control for therapist contact time, the health education control group will also receive brief telephone follow-up sessions that focus solely on reviewing the content of the educational modules, without incorporating any active sleep-related intervention strategies.
