Digital Mood-enhanced CBT-I to Improve Depressive Symptoms in Adolescents

This standard digital CBT-I intervention will cover (1) psycho-education about sleep, circadian and sleep hygiene education, (2) stimulus control, (3) sleep restriction, (4) relaxation techniques, (5) structured worry time, (6) cognitive restructuring (targeting sleep-related dysfunctional cognitions), and (7) relapse prevention. In order to have comparable dosage as modified CBT-I, the treatment will be dispersed to 8 modules (8-week) which is still in the range of standard CBT-I duration (usually last for 6-8weeks).

Additional depression specific components will be added to the standard CBT-I, including behavioral activation and problem solving.
