Effects of Digitally Delivered and Group-based CBT-I in Pregnant Women With Comorbid Insomnia and Depression

December 30, 2023 updated by: Dr. Shirley Xin Li, The University of Hong Kong

Efficacy of Digitally Delivered and Face-to-face Group Cognitive Behavioural Therapy for Insomnia in Pregnant Women With Comorbid Insomnia and Depression: A Randomised Controlled Trial

Major depressive disorder (MDD) is a debilitating and recurrent illness associated with a constellation of grave consequences and is among the most common psychiatric disorders during the pregnancy and postpartum periods. Meanwhile, sleep disturbance, particularly insomnia, is among the most prevalent and prominent presenting complaints in pregnant women with depression. Despite its high prevalence, insomnia often remains overlooked and under-treated in clinical practice. However, growing evidence suggests an intricate relationship between insomnia and depression, which has become an area in need of further focused attention. The optimal treatment for managing both antenatal depression and insomnia remains controversial. Only few pilot studies have evaluated the effects of cognitive behavioural therapy for insomnia (CBT-I) for antenatal insomnia. Whilst face-to-face CBT-I has shown the promise in managing insomnia in pregnant women, several barriers to implementation remain in clinical practice (e.g., a lack of trained therapists, long waiting time). Pregnant women also face additional unique barriers to obtaining insomnia treatment, including having other recurring prenatal health appointments, limitations in mobility or transportation, and financial concerns. There is growing evidence supporting the feasibility and comparable efficacy of digital CBT-I (effect size Cohen's d ranging from 0.69 to 0.8) as compared to a control intervention (e.g., sleep hygiene education, relaxation) for treating adult insomnia. However, little is known about the effects of different treatment modalities (group-based vs. app-based CBT-I) during pregnancy. This study aims to conduct a randomised controlled trial to examine the effects of group-based CBT-I and smartphone app-based CBT-I as compared to health education control condition in pregnant women with comorbid depression and insomnia on improving maternal sleep and depressive symptoms, other clinical and daytime symptoms, and overall functional improvement, as well as mother-infant-relationship.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

A randomised parallel-group controlled trial will be conducted in pregnant women with comorbid insomnia and depression. Eligible subjects will be randomised to one of the following groups: group-based CBT-I + Usual care (UC), app-based CBT-I + UC, or health education + UC. Randomization will be performed using stratified blocked randomization, stratified by the severity of insomnia at baseline. Assessments will be conducted at baseline and post-treatment (week 6/at the conclusion of last session). Subjects will be also assessed for their sleep and mood symptoms at week 2/at the conclusion of session 2 and week 4/at the conclusion of session 4. Subjects in the control group will be offered CBT-I after post-intervention follow-up. Additional assessments will be conducted in the two active treatment groups at postpartum 3-month and 6-month. A further follow-up assessment will be scheduled at 12-month postpartum to particularly examine whether intervention effects can sustain over time in the two treatment groups.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Group CBT-I
The group CBT-I will receive 6-session group-based CBT-I.
Behavioral: Group CBT-I
The group-based intervention will consist of 6 weekly sessions (90-min, 5-8 pregnant women in each group). The treatment components aim to address the behavioural, cognitive and physiological factors perpetuating insomnia with the followings: psycho-education about sleep and sleep hygiene (e.g., psychoeducation about sleep during pregnancy and normal development and patterns of infant sleep, psychoeducation on ways of improving infant sleep, strategies to limit the development of unwanted sleep associations, etc.), stimulus control, sleep restriction, relaxation training, structured worry time, cognitive restructuring (targeting sleep-related dysfunctional cognitions), and relapse prevention.
Experimental: App-based CBT-I
The app-based CBT-I group will receive 6-session CBT-I via smartphone.
Behavioral: App-based CBT-I
The smartphone app-based intervention will consist of 6 weekly sessions. The app-based intervention will involve a self-paced, fully automated digital programme with interactive components. The structure of the app involves six sequential modules (comparable to the six treatment sessions delivered in groups) with different elements to engage the users, such as animated videos, case vignettes, narration, quizzes, and homework assignment. Each module will be unlocked and released to the participants every week after the previous module has been completed. Personalised feedback will be provided by the app following the completion of sleep diary each week. Automated messages will be sent to the participants regularly via phone to remind them of implementing learned strategies after each module, as well as timely completing the treatment modules and sleep diaries.
Sham Comparator: Health-related psychoeducation control
The control group will receive group-based health-related psychoeducation, a format that has been adopted in the previous research, in order to provide the credibility of the intervention to the participants, and to control for the potential effects of attention and nonspecific components, e.g., receiving health-related information, expectations of benefit. It will also consist of 6 weekly sessions which contain education on healthy diet, exercise habits, sleep hygiene and self-care specific to pregnancy, but will not include any active therapeutic components of CBT-I.
Other: Health related psychoeducation
The control group will receive 6 sessions of group-based health-related psychoeducation, a format that has been adopted in the previous research, in order to provide the credibility of the intervention to the participants, and to control for the potential effects of attention and nonspecific components.
