A Theory-based Sleep Hygiene Education for Insomnia Disorder
7 juni 2026 uppdaterad av: YEUNG Wing Fai, The Hong Kong Polytechnic University
A Theory-based Sleep Hygiene Education for Insomnia Disorder - A Non-inferiority Randomized Controlled Trial With Mixed-method Process Evaluation and Cost-effectiveness Analysis
Insomnia is a prevalent sleep disorder associated with numerous adverse health outcomes, including fatigue, irritability, and impaired daytime functioning.
Despite the availability of effective pharmacological and psychological treatments, relatively few individuals with insomnia seek professional help, highlighting the need for accessible and acceptable non-pharmacological interventions.
Sleep hygiene education (SHE) has the potential to address this gap due to its simplicity, low cost, and ease of self-administration.
Building on our previously registered pilot-testing protocol, this study aims to examine the effectiveness of a theory-based SHE program integrated with behavior change techniques in a larger community population.
Furthermore, it remains unclear whether theory-based SHE is inferior to gold-standard interventions such as cognitive behavioral therapy for insomnia (CBT-I) delivered via digital applications.
Therefore, this study will also compare the effectiveness of theory-based SHE with a CBT-I app using a three-arm randomized controlled trial design.

Detaljerad beskrivning
Insomnia is a prevalent sleep disorder associated with substantial adverse health consequences, including fatigue, irritability, and impaired daytime functioning. Although effective pharmacological (e.g., hypnotics) and psychological treatments (e.g., cognitive behavioral therapy for insomnia, CBT-I) are available, both local and international surveys indicate that fewer than 50% of individuals with insomnia seek treatment. This treatment gap underscores the need for effective non-pharmacological interventions that are both accessible and acceptable.
Sleep hygiene education (SHE) represents a potentially suitable approach to address this unmet need. SHE is an educational intervention encompassing a range of lifestyle and environmental recommendations to optimize sleep quality and duration. These include maintaining a regular sleep-wake schedule, avoiding substances such as caffeine, nicotine, and alcohol, limiting daytime napping and stimulating activities before bedtime, optimizing the sleep environment, and adopting appropriate dietary and exercise habits etc. Given its simplicity, low cost, accessibility, and ease of delivery and adoption, SHE holds promise as a non-pharmacological strategy for insomnia management.
Despite these advantages, SHE is not typically recommended as a stand-alone treatment for individuals with sleep problems, as it is often perceived to be less effective than CBT-I or mindfulness-based interventions, with consistently small effect sizes reported. However, these findings should be interpreted with caution. In many previous studies, SHE has primarily been used as a passive control condition to account for nonspecific treatment effects, thereby underexploiting its active therapeutic potential. Moving SHE beyond a simple advice-giving modality to a structured, theory-informed approach may optimize its effectiveness by ensuring its content is informative and promising. Integrating SHE with established behavior change techniques may better equip individuals with the skills needed to initiate and sustain meaningful behavioral change.
Building on our previously registered pilot-testing protocol, this study aims to evaluate the effectiveness of a theory-based SHE program integrated with behavior change techniques in a larger community sample. In addition, it remains unclear whether theory-based SHE is inferior to gold-standard interventions such as digitally delivered CBT-I. This study will also examine whether a theory-based SHE program is a cost-effective approach for reducing insomnia severity in adults with insomnia disorder compared with a CBT-I app and a no-intervention control. To address these objectives, a three-arm randomized controlled trial will be conducted to compare the relative effectiveness of these interventions.

Experimentell: Sleep Hygiene Education
Participants in this group will receive a structured six-week SHE intervention.
The intervention includes two weekly 2-hour group-based, face-to-face educational sessions (total 4 hours) conducted in a classroom at the School of Nursing, The Hong Kong Polytechnic University, followed by four weekly individualized telephone consultations lasting approximately 10 minutes each.
During the educational sessions, participants will receive education on insomnia and evidence-based sleep hygiene practices, and will develop individualized behavior change plans to support sustained implementation of sleep hygiene practices.
The subsequent telephone consultations will reinforce adherence to these plans by reviewing progress, discussing barriers, and providing tailored feedback.

Aktiv komparator: CBT-I App
Participants in this group will receive a CBT-I program consisting of six weekly modules delivered in the Chinese language through a smartphone application proACT-S.
The duration of each module is around 45 to 60 min with interactive features.
The self-help CBT-I treatment content in proACT-S is based on the Chinese translated version of a well-established CBT-I treatment manual.
The self-help CBT-I treatment content is designed to alter dysfunctional cognitive beliefs and maladaptive behaviors that perpetuate insomnia.
The self-help CBT-I treatment content CBT-I aims at changing dysfunctional cognitive beliefs and maladaptive behaviors that contribute to the maintenance of insomnia.

Inget ingripande: Waitlist Control
Participants in this group will receive no intervention from the study.
They will be provided with the same SHE program and CBT-I apps after the follow-up period.
Waitlist control is chosen as previous surveys have revealed that almost half of individuals with clinical insomnia refrain from seeking any treatment.
Therefore, the waitlist control group reflects the typical help-seeking behavior of those coping with insomnia, thus providing a more realistic comparison for our study.
