- Brief Summary
This study aims to conduct a randomized controlled trial in comparing cognitive behavioral insomnia prevention program with the active control group in youths who are at risk of insomnia. The results of this study will allow us to take this potential efficacious prevention program to scale and reduce the associated burden of insomnia in the future.
- Detailed Description
Adolescence is a vulnerable period for the emergence of insomnia, which affects more than 10% of the youths (approximately 40% if based on symptoms). Insomnia in youths tends to run a protracted course and is associated with numerous negative outcomes including poor quality of life, cognitive and academic impairment, and predisposing to development of depression and anxiety. The burden arises from insomnia has been increasingly recognized worldwide as a debilitating and costly public health concern.
However, insomnia in youths is often ignored and under-treated, with only 10% of the local youths recognized their insomnia problem and none of them has received the recommended first-line treatment - cognitive behavioral therapy for insomnia (CBT-I). Given the high prevalence, chronicity and long-lasting health-related consequences of insomnia, together with the delay and limited help-seeking behavior, it calls the urgent need for early insomnia prevention and intervention in this vulnerable population.
Thus, this study aims to conduct a randomized controlled trial in comparing cognitive behavioral insomnia prevention program with the active control group in youths who are at risk of insomnia and to explore the effect of prevention program in preventing the incidence of insomnia problems.

Group Intervention Description Insomnia prevention program Insomnia prevention program The preventive program has been developed and modified as based on the evidence-based CBT-I insomnia treatment. Active intervention group will be conducted in group size with 6-8 subjects who are from the same education level (i.e. secondary vs university). Youths in the intervention group will receive 4 weekly insomnia prevention program conducted by the sleep therapists who has received training in conducting CBT-I under close supervision of sleep experts. Each session will last for about 60-90 mins. General health education General health education In order to control for placebo effect and other non-specific factors such as contact time, youths in the control group will be provided with group-based general health education with same dosage (4 weeks) as intervention group. Modules will contain information about general well-being, diet, nutrition, and activity. It is expected that this health education will be an active control group to account for most of the non-specific effects including time, attention, therapist, and peer support.
- Primary Outcome Measures
Name Time Method Insomnia disorder incidence 12-month follow up Clinician-rated insomnia incidence is defined as having insomnia symptoms for ≥ 3 times per week for at least one month (will be able to cover both acute and chronic insomnia disorder), accompanied with clinically significant distress or impairment. The assessment will be conducted based on the DSM-V insomnia diagnostic criteria checklist with the detail record of the symptom duration.
Change of insomnia symptoms baseline, week 5, 3-, 6-, and 12-month follow up The severity of insomnia symptoms as measured by 7-item Insomnia Severity Index (ISI). ISI is a self-report measure designed to assess the nature, severity and impact of insomnia, with a higher total score suggesting more severe insomnia symptoms. Scores range from 0 to 28.
- Secondary Outcome Measures
Name Time Method Change of academic performance baseline and 12-month follow up Official record of academic performance at both baseline and end of study (at 12 months) will be collected.
Change of adolescent's perception and attitude towards sleep baseline, week 5 3-, 6-, and 12-month follow up Adolescent's perception and attitude towards sleep will be captured by 10-item Charlotte Attitudes Towards Sleep Scale (CATS). The CATS Scale included 2 subscales: the Benefits subscale the Time Commitment subscale. The 5 items within each subscale can be averaged, and all 10 items can be averaged to create a total score ranging from 1 to 7, with higher scores indicating more favorable attitudes towards sleep.
Change of self-reported cognitive failures baseline, week 5, 3-, 6-, and 12-month follow up Cognitive Failures Questionnaire (CFQ) is an indicator of self-reported failures in perception, memory, and motor function, with a higher score indicating an increased vulnerability to stress. Scores range from 0 to 100.
Change of health related quality of life baseline, week 5, 3-, 6-, and 12-month follow up Quality of life will be measured by kidscreen-27 Health related quality of life (HRQoL) that consists of 27 items to assess five dimensions of quality of life, including physical well-being (possibly scored from 5 to 25), psychological well-being (possibly scored 7 to 35), autonomy \& parents (possibly scored 7 to 35), peers \& social support (possibly scored 4 to 20), and school environment (possibly scored 4 to 20). A grand total score can be calculated by summing up the five sub scores. In all cases, a higher score represents higher perceived well-being.
Change of sleep hygiene baseline, week 5, 3-, 6-, and 12-month follow up Adolescent sleep behaviors will be measured by Adolescent Sleep Hygiene Scale revised (ASHSr). ASHSr is a self-reported questionnaire with eight subscales: physiological, cognitive, emotional, sleep environment, daytime sleep, substance, sleep stability and bedtime routine. A higher score indicates a better sleep practice. The total score is calculated from the average score of all the items on the scale and could range from 1 to 6.
Change of pre-sleep arousal behaviors baseline, week 5, 3-, 6-, and 12-month follow up Pre-Sleep Arousal Scale (PSAS) is a 16-item, self-reported questionnaire comprising both cognitive and somatic manifestations of arousal, with eight items in each subscale. Two subscale scores ranging from 8 to 40 were computed separately. A higher score suggesting higher pre-sleep arousal.
Change of sleep-related thoughts and behaviors baseline, week 5, 3-, 6-, and 12-month follow up Sleep-related thoughts and behaviors will be measured by Brief Version of Dysfunctional Beliefs and Attitudes about Sleep (DBAS-16). DBAS-16 is a 16-item self-report measure designed to evaluate a subset of those sleep related cognition, with a higher score indicating more dysfunctional beliefs and attitudes about sleep. The total score is calculated from the average score of all the items on the scale and could range from 0 to 10.
Change of daytime sleepiness baseline, week 5 3-, 6-, and 12-month follow up Daytime sleepiness will be measured by Pediatric Daytime Sleepiness Scale (PDSS). It is an 8-item inventory designed for use with school children and youths, with a higher score indicating greater sleepiness. Scores ranged from 0 to 32.
Daytime fatigue baseline, week 5, 3-, 6-, and 12-month follow up Daytime fatigue will be assessed by Multidimensional Fatigue Inventory (MFI) that measure five dimensions of fatigue, including general fatigue, physical fatigue, mental fatigue, reduced motivation and reduced activity. MFI is a self-report instrument consisting of 20 items. Each subscale contains four items. The total scores of each subscale range from 4 to 20, with a higher score indicating greater fatigue.
Change of anxiety and depressive symptoms baseline, week 5, 3-, 6-, and 12-month follow up Anxiety and depressive symptoms will be measured by Hospital Anxiety and Depression Scale (HADS). The HADS consists of two subscales for anxiety (HADS-A) and depression (HADS-D). A higher total score of each subscale represents a greater severity of depression/anxiety. The total score for each subscale ranges from 0 to 21.
Change of sleep parameters as measured by 7-day sleep diary baseline, week 5, 3-, 6-, and 12-month follow up Seven-day sleep diary is a prospective measure that includes the questions to assess time in bed, sleep duration, wake after sleep onset, sleep latency and sleep efficiency.
Change of score in vulnerability to stress-related insomnia baseline, week 5, 3-, 6-, and 12-month follow up Vulnerability to stress-related insomnia will be measured by Ford Insomnia Response to Stress Test (FIRST). It includes nine items, and participants were asked to rate on a 4-point Likert scale to indicate their likelihood of sleep disturbance in response to the commonly experienced stressful situations. A higher total score represents a greater vulnerability of sleep disturbance. The total score ranges from 9 to 36.
