NCT06023693

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.

Outcome Measures

Primary Outcomes (1)

  • Insomnia Severity Index

    7-item self-report instrument to assess insomnia severity, scores 0-28, higher scores indicating more insomnia severity

    Baseline (T0), 3 weeks after baseline (T1), 6 weeks after baseline (T2), and 18 weeks after baseline (T3)

Secondary Outcomes (15)

  • Sleep efficiency (in minutes)

    Change from week 1 to week 7

  • Sleep onset latency (in minutes)

    Change from week 1 to week 7

  • Wake after sleep onset (in minutes)

    Change from week 1 to week 7

  • Early morning awakening (in minutes)

    Change from week 1 to week 7

  • Total sleep time (in minutes)

    Change from week 1 to week 7

  • +10 more secondary outcomes

Other Outcomes (5)

  • Adherence - Total number of completed modules

    Through study completion, an average of 18 weeks

  • Adherence - Time spent in the platform (in minutes)

    Through study completion, an average of 18 weeks

  • Adherence - Number of logins (total amount)

    Through study completion, an average of 18 weeks

  • +2 more other outcomes

Guided online self-help intervention

EXPERIMENTAL

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.

Behavioral: i-Sleep & BioClock

Online psychoeducation

ACTIVE COMPARATOR

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.

Behavioral: Online Psychoeducation

Interventions

Module 1 Psychoeducation about normal sleep and insomnia, Psychoeducation on the biological clock: the circadian rhythm, chronotypes, zeitgebers, importance of light behaviour Basic sleep hygiene: information about behaviours that are known to promote or impede sleep e.g. performing physical exercise or the use of caffeine Module 2 Sleep restriction and stimulus control: patients are taught to use the bedroom only to sleep and to restrict the time in bed to the average amount of night-time sleep Module 3 Worrying and relaxation: audio files with progressive muscle relaxation exercises are offered and techniques to stop worrying (e.g. thought blocking, evaluation and worry time) Module 4 Erroneous cognitions about sleep: the basics of cognitive behavioural therapy are explained and the most common erroneous ideas about insomnia are discussed Module 5 Summary and plan for the future
