Low-intensity Cognitive-behavioural Therapy for Insomnia

23. marts 2020 opdateret af: Dr. Chung Ka-Fai, The University of Hong Kong

A Randomized Controlled Trial to Compare the Effects of Cognitive Behavioral Therapy Workshop, Sleep Hygiene Education Workshop and Self-Help Cognitive Behavioral Therapy on Adults With Sleep Impairment in Hong Kong

A randomized controlled trial is proposed to compare the effectiveness of workshop-based and self-Help cognitive behavioral therapy for insomnia (CBTI), and sleep hygiene education (SHE) to treat insomnia in Hong Kong adolescent and adult patients, in terms of alleviation of insomnia severity, reduction in associated insomnia symptoms/ complications, and enhancement in quality of life. Insomnia is prevalent in Hong Kong and can cause severe impacts on patients and society, but there is a dearth of related research in the local population. Therefore, it is significant to conduct this study. A total of 210 participants aged > 18 with insomnia will be recruited and randomized into 3 groups to receive one of the 3 treatments. Outcomes will be measured using relevant questionnaires filled in at the baseline, 6 and 12 weeks afterwards. The results obtained will be compared within each group and among the 3 groups using statistical testing to determine the most effective treatment option for insomnia.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: CBTI Workshop
The first intervention group (Group 1) will attend one half-day CBTI workshop in the community setting. The workshop is subdivided into 4 sessions, covering topics regarding regulation of stimuli, limit of sleeping duration, relaxation, sleep hygiene and alteration of cognitive beliefs (Arnedt, Cuddihy, & Swanson, et al, 2014; Morin, Savard, Ouellet, & Daley, 2003). One workshop has the capacity of 30 participants.
CBTI involves habitual, belief and attitude alterations so as to eliminate factors preventing sleep (Morin, Savard, Ouellet, & Daley, 2003). It is recommended by the American College of Physicians as the first-line therapy for insomnia (Qaseem, Kansagara, Forciea, Cooke, & Denberg, 2016). CBTI workshops are a relatively novel and emerging way of delivery which involves a greater number of patients than group CBTI, increases availability and accessibility by concentrating the content into half or whole day and taking place in the community settings, and reduces diagnostic labeling and cost (Bonin, Beecham, Swift, Raikundalia, & Brown, 2014; Swift, Stewart, Andiappan, Smith, Espie, & Brown, 2012). Self-help CBTI involves independent learning of the provided materials via the Internet, video or audio recording, books and pamphlets (Bruin, Bogels, Oort, & Meijer, 2015).
Eksperimentel: Self-Help CBTI
The second intervention group (Group 2) will receive self-help CBTI. A CBTI webpage will be set up and the subjects are asked to review all the materials in it. The content is the same as that in Group 1.
CBTI involves habitual, belief and attitude alterations so as to eliminate factors preventing sleep (Morin, Savard, Ouellet, & Daley, 2003). It is recommended by the American College of Physicians as the first-line therapy for insomnia (Qaseem, Kansagara, Forciea, Cooke, & Denberg, 2016). CBTI workshops are a relatively novel and emerging way of delivery which involves a greater number of patients than group CBTI, increases availability and accessibility by concentrating the content into half or whole day and taking place in the community settings, and reduces diagnostic labeling and cost (Bonin, Beecham, Swift, Raikundalia, & Brown, 2014; Swift, Stewart, Andiappan, Smith, Espie, & Brown, 2012). Self-help CBTI involves independent learning of the provided materials via the Internet, video or audio recording, books and pamphlets (Bruin, Bogels, Oort, & Meijer, 2015).
Aktiv komparator: SHE Workshop
The control group (Group 3) will receive SHE. To ensure uniformity of the therapy model, the participants will also need to attend one half-day face-to-face session, covering topics related to sleep hygiene only. The capacity is also 30 participants.
SHE, is commonly provided verbally or through leaflets during consultations (Espie, 2009), and is also included as a part of CBTI (Morin, Savard, Ouellet, & Daley, 2003).
