About this study

Official title: Effects of Group Cognitive Behavioural Therapy on Comorbid Insomnia and Depression in Youth: a Randomised, Assessor Blind, Parallel Group Trial

Major depressive disorder (MDD) is among the most common psychiatric disorders among adolescents, and is associated with considerable psychosocial and functional impairments and an elevated risk of suicidal behaviour and completed suicide. Meanwhile, sleep disturbance, particularly insomnia, is among the most prevalent and prominent presenting complaints in adolescents with depression. Despite its high prevalence, insomnia often remains overlooked and under-treated in clinical practice. However, growing evidence suggests an intricate relationship between insomnia and depression, which has become an area in need of further focused attention. This project will involve a randomised controlled trial proposed to examine whether insomnia treatment confers additional benefit to depression treatment in adolescents with comorbid depression and insomnia, for improving sleep and depressive symptoms, and other clinical and daytime symptoms as well as overall functional improvement in both the short and long term. Eligible adolescent participants will be randomised to either intervention (8-week group Cognitive Behavioural Therapy for Insomnia, CBT-I, or 8-week group Cognitive Behavioural Therapy for Depression, CBT-D) or waiting-list control condition. Assessments will be conducted at pre-treatment (week 0), during the treatment (week 2, 4, 6) and post-treatment (week 8/at the conclusion of the last group session). The two active treatment groups will be additionally followed up at posttreatment one-month and six-month.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Cognitive Behavioural Therapy for Insomnia (CBT-I)Behavioural

    The intervention will consist of 8 weekly group sessions (90-min, 5-8 adolescents in each group) of CBT-I delivered within a 10-week window. The treatment components in the CBT-I aim to address the behavioural, cognitive and physiological perpetuating factor of insomnia and include: psycho-education about sleep and sleep hygiene, stimulus control, sleep restriction, relaxation training, structured worry time, cognitive restructuring (targeting sleep-related dysfunctional cognitions), and relapse prevention.

  • Cognitive Behavioural Therapy for Depression (CBT-D)Behavioural

    The intervention will consist of 8 weekly group sessions (90-min, 5-8 adolescents in each group) of CBT-D delivered within a 10-week window. The main treatment elements of CBT-D include: psycho-education about depression, self-monitoring, behavioural activation, improving social skills, communication skills and problem solving skills, cognitive restructuring (addressing negative and irrational thoughts often associated with depression in adolescents), relaxation techniques, and relapse prevention.

The record says: finished, as of the sponsor's last update on 24 May 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Hong Kong. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change of depressive symptoms (assessor-rated) (time frame: Baseline, post-treatment (week 8/at the conclusion of last group session) for all participants; and additionally at post-treatment one-month, six-month and 24-month for those in the two active treatment groups). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
