- Brief Summary
This randomized controlled trials aims to assess the effectiveness of an online guided self-help intervention ('i-Sleep \& BioClock') based on CBTi principles for university students' sleep problems. The study will involve 192 students with subthreshold insomnia who will be randomized to the intervention or online psychoeducation. The intervention consists of 5 modules completed in about 5 weeks, supported by e-coaches. Outcomes include insomnia severity, mental health symptoms, functioning, quality of life, and academic performance, measured at baseline, post-treatment (6 weeks after baseline), and 18 weeks follow-up.
- Detailed Description
Rationale: University students often suffer from sleep problems which affect their mental health and daily functioning. Cognitive behavioural therapy for insomnia (CBTi) has been proven effective in adults, but research in university students is still limited. The investigators hypothesize that a guided e-health self-help intervention based on CBTi principles ('i-Sleep \& BioClock') could offer convenient treatment to students with sleep problems by reducing insomnia severity and improving mental health outcomes.
Objective: The aim of this randomized controlled trial is to assess the effectiveness of a guided e-health sleep and biological clock intervention on sleep, mental health symptoms (depression and anxiety), functioning, quality of life, and academic performance in university students.
Study design: This is a two-arm parallel group superiority randomized controlled trial, comparing a guided e-health intervention based on CBTi to online psychoeducation (PE).
Study population: The aim is to include 192 university students (Bachelor, Master and PhD) with at least subthreshold insomnia (Insomnia Severity Index ≥ 10), aged ≥ 16, who are able to speak Dutch or English, and are affiliated to one of the nine participating universities. Students with current suicidal ideation are excluded.
Intervention: The intervention will be a guided e-health intervention based on CBTi principles (i-Sleep \& BioClock). It consists of 5 modules, to be completed in about 5 weeks, and is aimed at improving sleep in university students. The intervention will be entirely held online and will be supported by e-coaches.
Main study parameters/endpoints: The primary outcome will be insomnia severity. Secondary outcomes will be depression, anxiety, daily functioning, academic performance, quality of life, and sleep \& light exposure diary outcomes. Outcomes will be measured at baseline, at post-treatment (6 weeks after baseline), and at 18 weeks follow-up. Mediators such as shift in chronotype and light exposure will be examined at baseline, mid-treatment, and post-treatment

Group Intervention Description Online psychoeducation Online Psychoeducation The control group will receive access to the platform and to the sleep diary. Their intervention will consist of brief, unstructured online PE for insomnia based on recognized sleep hygiene advice, for example, recommendations about evening routines, and use of alcohol and caffeine. Students will be advised to monitor their sleep in the diary. In contrast to the intervention group, the control group will not receive support of an e-coach. Key differences to the CBTi group are that the online PE (1) does not provide individualized support by an e-coach; (2) includes less content, and (3) is not delivered in a step-by-step manner, but will be provided all at once. Guided online self-help intervention i-Sleep & BioClock The intervention will be a guided e-health intervention based on CBTi principles (i-Sleep \& BioClock). It consists of 5 modules, to be completed in about 5 weeks, and is aimed at improving sleep in university students. The intervention will be entirely held online and will be supported by e-coaches. The topics covered will be sleep hygiene, psychoeducation on sleep and the biological clock, sleep restriction, stimulus control, worrying and relaxation, dysfunctional thoughts, and relapse prevention.
- Primary Outcome Measures
Name Time Method Insomnia Severity Index Baseline (T0), 3 weeks after baseline (T1), 6 weeks after baseline (T2), and 18 weeks after baseline (T3) 7-item self-report instrument to assess insomnia severity, scores 0-28, higher scores indicating more insomnia severity
- Secondary Outcome Measures
Name Time Method Sleep efficiency (in minutes) Change from week 1 to week 7 Derived from sleep and light exposure diary
Total sleep time (in minutes) Change from week 1 to week 7 Derived from sleep and light exposure diary
Sleep onset latency (in minutes) Change from week 1 to week 7 Derived from sleep and light exposure diary
Wake after sleep onset (in minutes) Change from week 1 to week 7 Derived from sleep and light exposure diary
Early morning awakening (in minutes) Change from week 1 to week 7 Derived from sleep and light exposure diary
Time spent outside (in minutes) Change from week 1 to week 7 Derived from sleep and light exposure diary
Screen use before bed Change from week 1 to week 7 Yes/ No question. Derived from sleep and light exposure diary
Munich Chronotype Questionnaire (MCTQ) Baseline (T0), 6 weeks after baseline (T2), and 18 weeks after baseline (T3) Self-rated scale to assess individual phase of entrainment on work and work-free days, Addresses questions about: bedtime (actual time), time spent in bed awake before deciding to turn off the lights (in minutes), how long it takes to fall asleep (in minutes), wake up time (actual time), get up time (actual time) on work and work-free days. MCTQ uses the midpoint between sleep on- and offset on free days (mid-sleep on free days, MSF) to assess chronotype. The MCTQ chronotype is expressed in local time, in which earlier time refers to earlier chronotype and later time to later chronotype.
Work and Social Adjustment Scale (WSAS) Baseline (T0), 6 weeks after baseline (T2), and 18 weeks after baseline (T3) 5-item self-report instrument for impairment of functioning, scores ranging from 0-40, higher scores indicating more impairment in functioning
Patient Health Questionnaire (PHQ-9) Baseline (T0), 6 weeks after baseline (T2), and 18 weeks after baseline (T3) 9-items self-report instrument for severity of depressive symptoms, scores ranging from 0-27, higher scores indicating more severe depression
Generalised Anxiety Disorder scale (GAD-7) Baseline (T0), 6 weeks after baseline (T2), and 18 weeks after baseline (T3) 7-items self-report instrument for severity of anxiety symptoms, scores ranging from 0-21, higher scores indicating more severe anxiety
Mental Health Quality of Life questionnaire (MHQoL) Baseline (T0), 6 weeks after baseline (T2), and 18 weeks after baseline (T3) 7-item self report instrument for quality of life measure for use in people with mental health problems, scores ranging from 0-21, higher scores indicating higher quality of life, and MHQoL-VAS visual scale ranging from 0 (worst imaginable psychological wellbeing) to 10 (best imaginable psychological wellbeing)
Academic performance Baseline (T0), 6 weeks after baseline (T2), and 18 weeks after baseline (T3) Students will be asked about the grade of their last exam (Scale 1-10), the average grade of the past semester (Scale 1-10), whether they failed any exams in the past semester (Yes/No), and their study progression in the past semester in terms of ECTS achieved (30 ECTS per semester, Yes/No)
