Intervention/exposure

Description of intervention(s) / exposure
This project aims to evaluate the feasibility and potential efficacy of a manualised Cognitive Behavioural Therapy for Insomnia (CBT-I) intervention for Vietnamese-speaking head and neck cancer survivors delivered via telehealth.

CBT-I is an evidence-based intervention that is considered the gold standard treatment for insomnia. The intervention consists of six weekly 1-hr sessions based on existing CBT-I treatment protocols and adapted for delivery in Vietnamese. The key goal for CBT-I is to change dysfunctional sleep habits and thinking patterns that contribute to sleep difficulties, with sessions involving a combination of education about sleep, behavioural interventions, and cognitive interventions. The session outline is as follows:
• Session 1: Education about sleep
• Session 2: Sleep restriction (involves reducing the overall time an individual spends in bed, with the aim of increasing the percentage of time spent asleep while in bed), and stimulus control (involves retraining the brain to associate the bed/bedroom with being asleep instead of being awake)
• Session 3: Sleep hygiene (involves learning helpful habits for sleep), and education about sleep medications
• Sessions 4 and 5: Cognitive restructuring (involves identifying and learning tools to manage dysfunctional thoughts that contribute to insomnia)
• Session 6: Relapse prevention (involves learning strategies to reduce the severity and likelihood of a relapse occurring)

CBT-I MATERIALS
To accompany the treatment manual, participants will be provided with an existing CBT resource developed by the Clinical Psychology team at Peter MacCallum Cancer Centre, titled “Can-Sleep: Making Night Time Sleep Problems Go Away”. This resource is a 27-page colour printed booklet, which was developed based on CBT-I protocols and includes information about sleep and strategies to help improve sleep as listed above. This resource is currently used in routine clinical practice at Peter Mac and has undergone translation to Vietnamese. The translation was completed by an accredited translation service.

Where there are gaps in the Can-Sleep resource, participants will be provided with additional materials to support the topics covered in the session outline above. These materials are versions of CBT-I handouts used in routine clinical practice, and may include:
• A sleep diary and/or sleep journal, to assist participants with tracking their sleep habits
• Information about dysfunctional thinking patterns that may contribute to sleep difficulties

These handouts have undergone translation to Vietnamese following Peter Mac’s translation guidelines. Additional materials may be developed as required, which will be submitted to HREC for approval prior to translation and delivery to participants.

FIDELITY
Each session recording and transcription will be assigned a unique session identifier. Transcriptions for a random selection of 25% of sessions will be checked against the recordings for accuracy and then translated to English. The English transcriptions will then be assessed by an objective rater. The rater will score the fidelity to the intervention based on a standardised scoring framework. Adaptations made to sessions will also be recorded.

Statistical methods / analysis
20 participants will be recruited in this feasibility study. 20 participants was chosen for pragmatic reasons, including available funding and timeline for project completion.

Descriptive statistics will be used to summarise patient characteristics, compliance with study measures, responses to the acceptability questionnaire, and fidelity data. Consent and retention data, as well as intervention adherence, will be summarised using a proportion and 95% CI. Recruitment data will be summarised using a rate and 95% CI using the Poisson distribution. Sleep outcomes will be analysed using analysis-of-covariance adjusted for the baseline value of the corresponding outcome.

Data will be managed through REDCAP and all analyses will be performed in R and/or excel.

Free text items from the patient experience surveys will be analysed using summarising content analysis using NVivo software. A deductive content analysis approach will be used for coding data. Pre-defined categories will be formulated based on the research questions informing the study. Additional inductive codes will be identified from the survey responses.

Summary
Brief summary
This study aims to evaluate a telehealth cognitive behavioural therapy intervention for insomnia (CBT-I) in Vietnamese-speaking cancer survivors, delivered by a Vietnamese-speaking psychologist.

Who is it for?
You may be eligible for this study if you are aged 18 years or over and can speak and read Vietnamese, and have completed curative treatment (e.g., surgery, chemotherapy, radiotherapy) for head and neck cancer and are now experiencing clinically significant insomnia symptoms.

Study details
Participants will undergo a six-session CBT-I intervention delivered weekly over telehealth. Upon completion of the intervention, participants will be asked to complete a few questionnaires regarding acceptability of the treatment and changes in their insomnia.

It is hoped that this study will help provide evidence for CBT-I delivered for a Vietnamese population and help address inequalities in accessing evidence-based health care for people from Vietnamese-speaking backgrounds.
