Participants in both groups will be also instructed to undergo morning light therapy (by wearing Re-timers) at home for 30 minutes daily. Re-timers can be worn like a pair of glasses, with 2 light-emitting diodes (LEDs) per eye. The following two conditions will be delivered by Re-timers: participants in the CBT-I group will receive a placebo light intervention where they will be exposed to dim red light (50lux), whereas participants in the CBT-I plus light therapy group will receive the active light treatment, with 2 LEDs emitting constant diffused blue-green light (500 nm, 506 lux).Masking: Double (Participant, Outcomes Assessor)Primary Purpose: Treatment

A randomised, assessor-blind, parallel group controlled trial will be conducted in youth with insomnia and eveningness. Eligible participants will be randomised to one of the following groups: CBT-I, CBT-I plus bright light therapy, or waiting-list control. Randomisation will be carried out using an automated online system. Assessments will be conducted at pre-treatment (week 0), during the treatment (week 2 & 4) and post-treatment (week 6/at the conclusion of the last group session). The two active treatment groups will be additionally followed up at post-treatment one-month and post-treatment six months in order to examine the maintenance effects following the intervention with CBT-I and CBT-I plus bright light therapy respectively.
