Clinical Trial 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.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Major life events and self-perceived stress	Major life events and self-perceived stress associated with these events that an individual experienced over the year will be measured by 57-item Life Experience Survey (LES). Ratings are on a 7-point scale ranging from extremely negative (-3) to extremely positive (+3). Summing the impact ratings of those events designated as positive by the subject provides a positive change score. A negative change score is derived by summing the impact ratings of those events experienced as negative by the subject. By adding these two values, a total change score can be obtained, representing the total amount of rated change, and can range from 0 to 171.	baseline and 12-month follow up
Other	Change of chronotype	The chronotype of the study participants will be measured by Morningness-Eveningness Questionnaire (MEQ). The rMEQ is a 5-item self reported measure used to evaluate circadian rhythm and sleep rhythm patterns in individuals. Individuals scored higher than 17 and lower than 12 were classified as morning-type and evening-type, respectively. Individuals scored between 12 and 17 were classified as intermediate-type. Scores range from 4 to 25.	baseline, week 5, 3-, 6-, and 12-month follow up
Other	Self-reported pubertal status	Tanner staging of breasts for females or genitals for males and pubic hair presented in pictures with text descriptions will be used to determine the pubertal status. A rating falls between tanner stages of one to three is classified as the pre-pubertal stage, while tanner stages four and five is classified as the post-pubertal stage.	baseline and 12-month follow up
Other	Treatment satisfaction, adherence and integrity	The TSS consists of 7 items with higher scores indicating greater symptom improvement. Overall treatment satisfaction was computed as the average score which ranges from 1 to 5 on all 7 items of the TSS.	week 5
Other	Treatment adherence	Treatment Component Adherence Scale (TCAS) will be used to assess treatment adherence at post intervention. The TCAS consists of 6 items with higher scores indicating better adherence. Scores range from 0 to 18	week 5
Other	Treatment expectancy and credibility	Credibility-Expectancy Questionnaire (CEQ) for assessment of treatment expectancy and credibility of the intervention. The CEQ consists of 6 items with higher scores indicating greater perceptions of treatment credibility and expectations of improvement. Scores range from 5 to 30.	week 5
Primary	Insomnia disorder incidence	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.	week 5
Primary	Insomnia disorder incidence	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.	3-month follow up
Primary	Insomnia disorder incidence	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.

Primary	Insomnia disorder incidence	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.	12-month follow up
Primary	Change of insomnia symptoms	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.	baseline, week 5, 3-, 6-, and 12-month follow up
Secondary	Change of sleep parameters as measured by 7-day sleep diary	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.	baseline, week 5, 3-, 6-, and 12-month follow up
Secondary	Change of score in vulnerability to stress-related insomnia	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.	baseline, week 5, 3-, 6-, and 12-month follow up
Secondary	Change of sleep-related thoughts and behaviors	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.	baseline, week 5, 3-, 6-, and 12-month follow up
Secondary	Change of daytime sleepiness	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.	baseline, week 5 3-, 6-, and 12-month follow up
Secondary	Daytime fatigue	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.	baseline, week 5, 3-, 6-, and 12-month follow up
Secondary	Change of self-reported cognitive failures	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.	baseline, week 5, 3-, 6-, and 12-month follow up
Secondary	Change of anxiety and depressive symptoms	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.	baseline, week 5, 3-, 6-, and 12-month follow up
