NCT02558647

Brief Summary

Insomnia is a major public health concern. While cognitive behavior therapy for insomnia (CBT-I) is acknowledged as the best available intervention, there are unanswered questions about its wider dissemination, socio-economic benefits and its impact on health resource utilization. The aim of this randomized controlled trial (RCT) is to investigate the effectiveness of a fully automated online version of CBT-I compared with online patient education about sleep (PE). Outcome measures comprise changes in symptoms of insomnia, time off work due to sick leave, as well as medication and health resource utilization. Also, we will examine putative mediators and selected potential psycho-bio-social moderators of the effects of the intervention.

Outcome Measures

Primary Outcomes (1)

  • Insomnia Severity Index, ISI

    The ISI will be used to assess self-reported levels of insomnia severity. Range is 0-28. Higher values represent higher levels of insomnia symptom severity.

    Pre to 9 weeks post randomization (post treatment assessment)

Secondary Outcomes (26)

  • Insomnia Severity Index, ISI

    Pre, 6 months follow-up (6 months and 9 weeks after randomization), 24 months follow-up (24 months and 9 weeks after randomization)

  • Sleep diaries

    Pre, 9 weeks after randomization (post assessment), 6 months follow-up (6 months and 9 weeks after randomization), 24 months follow-up (24 months and 9 weeks after randomization)

  • Hospital Anxiety and Depression Scale, HADS

    Pre, 9 weeks after randomization (post assessment), 6 months follow-up (6 months and 9 weeks after randomization), 24 months follow-up (24 months and 9 weeks after randomization)

  • Short Form-12, SF-12

    Pre, 9 weeks after randomization (post assessment), 6 months follow-up (6 months and 9 weeks after randomization), 24 months follow-up (24 months and 9 weeks after randomization)

  • Dysfunctional Beliefs About Sleep scale, DBAS

    Pre, 9 weeks after randomization (post assessment), 6 months follow-up (6 months and 9 weeks after randomization), 24 months follow-up (24 months and 9 weeks after randomization)

  • +21 more secondary outcomes

Other Outcomes (1)

  • Salivary sample

    Single sample 24 months and 9 weeks after randomization (depending on funding/ethics approval for this component of the study)

Study Arms (2)

CBT for insomnia (CBT-I)

EXPERIMENTAL

Internet-based cognitive-behavioral therapy for insomnia (CBT-I) comprises a fully automated, interactive, and tailored web-based program that incorporates the primary tenets of face-to-face CBT-I, including sleep restriction, stimulus control, cognitive restructuring, sleep hygiene, and relapse prevention

Behavioral: CBT for insomnia (CBT-I)

Psychoeducation about Sleep (PE)

ACTIVE COMPARATOR

The PE intervention gives participants access to a website with information about insomnia symptoms; the impact, prevalence, and causes of insomnia; when to seek input from a doctor; and basic lifestyle, environmental, and behavioral strategies that may help to improve sleep.

Behavioral: Psycho-Education about Sleep (PE)

Interventions

CBT-I is an online, fully automated, interactive, and tailored web-based program that incorporates the primary tenets of face-to-face CBT-I, including sleep restriction, stimulus control, cognitive restructuring, sleep hygiene, and relapse prevention.

Also known as: SHUTi
CBT for insomnia (CBT-I)

PE provides online information about insomnia symptoms; the impact, prevalence, and causes of insomnia; when to seek input from a doctor; and basic lifestyle, environmental, and behavioral strategies that may help to improve sleep.

Also known as: passive education/ sleep hygeine

Eligibility Criteria

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

You may qualify if:

  • Individuals aged \>=18 years who score \>= 12 on the Insomnia Severity Index (a score indicative of insomnia symptoms that significantly impact on individuals)
  • Willing and able to give online informed consent.

You may not qualify if:

  • Individuals scoring \>10 on the Epworth Sleepiness Scale (ESS) (which is suggestive of excessive daytime sleepiness) and/or answering that they usually or every day snore and stop breathing and have difficulties staying awake during the day (i.e., they positively endorse pre-selected indicators of sleep apnoea);
  • Self-report of the presence of any medical conditions where a fully automated CBT-I may be contra-indicated (e.g. epilepsy, bipolar disorder, schizophrenia or psychotic disorders, and recent heart surgery)
  • Participating in shift work.
