Brief Summary

Previous research has shown the efficacy of (combinations of) individual components of cognitive behavioral therapy for insomnia (CBT-I), namely sleep hygiene education, sleep optimization, stimulus control therapy, deactivation/relaxation training, and cognitive therapy. However, their relative effects, i.e., their effects in direct comparison with each other, are yet to be assessed. In this pilot study, a smartphone and web application developed to treat insomnia using these treatment components will be tested. Two future studies will investigate the components' relative efficacy in order to identify the most effective component or combination of components for digitized treatment of chronic insomnia by means of the Multiphase Optimization Strategy (MOST), and verify this intervention's effect in a randomized controlled trial (RCT).

Outcome Measures

Primary Outcomes (1)

  • Insomnia severity post-intervention

    Assessed with the Insomnia Severity Index (ISI), with scores ranging from 0 to 28, where higher scores indicate higher insomnia severity, and a score equal to or above 10 indicates clinical significance.

    11 weeks after study entry (randomization)

Secondary Outcomes (10)

  • Sleep diary assessed sleep efficiency (SE) at end of intervention

    Approximately 10 weeks after study entry (randomization)

  • Sleep diary assessed sleep onset latency (SOL) at end of intervention

    Approximately 10 weeks after study entry (randomization)

  • Sleep diary assessed wake after sleep onset (WASO) at end of intervention

    Approximately 10 weeks after study entry (randomization)

  • Sleep diary assessed nocturnal awakenings (NA) at end of intervention

    Approximately 10 weeks after study entry (randomization)

  • Sleep diary assessed total sleep time (TST) at end of intervention

    Approximately 10 weeks after study entry (randomization)

  • +5 more secondary outcomes

Study Arms (2)

Intervention

EXPERIMENTAL

Administration of sleep hygiene, sleep optimization, stimulus control therapy, deactivation/relaxation training, and cognitive therapy.

Behavioral: eCBT-I

Control

NO INTERVENTION

Waitlist control (sleep diary only); access to treatment after final measurement

Interventions

eCBT-IBEHAVIORAL

Automated digital administration of sleep hygiene, sleep optimization, stimulus control therapy, deactivation/relaxation training, and cognitive therapy modules via mobile or web application, lasting approximately six weeks.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

Data Sharing

IPD Sharing
Will share

All individual participant data collected during the study will be made available in an irreversibly anonymized form. However, only data of those participants can be shared who have explicitly given consent to this as part of their informed consent to study participation. This means that it may not be possible to share all data underlying a certain publication. Data will be shared exclusively for research purposes.

Shared Documents
STUDY PROTOCOL, SAP, ICF
Time Frame
No later than six months after publication, no end date.
Access Criteria
Data will be shared exclusively with other researchers and for research purposes only. Researchers requesting the data will have to provide a methodologically sound research proposal clarifying how the data will be used and for what purpose.
