Brief Behavioural Treatment for Insomnia in Dementia Carers

December 9, 2016 updated by: NHS Greater Glasgow and Clyde

Brief Behavioural Treatment for Insomnia (BBTI) in Family Carers of People With Dementia: a Feasibility Study

Background: between 50-74% of dementia carers report some sleep disturbance. However, relatively few studies have looked at psychological treatment for insomnia in this group. Dementia carers may be particularly at risk for suffering negative consequences from the impact of sleep loss on top of the stress of their carer role. Researchers have found that Brief Behavioural Treatment for Insomnia (BBTI) can be effective for improving symptoms of insomnia in older adults. BBTI focusses on sleep-related behaviour such as napping and when a person gets up and goes to bed.

Aims: this study aims to explore whether delivering group-based, Brief Behavioural Treatment for Insomnia (BBTI) to family carers of people with dementia is feasible, given that, to date, this has not yet been explored.

Who is eligible?: carers with insomnia who care for a family member with dementia and live with them at home are eligible for inclusion in this study.

What is involved for participants?: taking part will involve an initial telephone discussion with a researcher to check suitability. Participants will then meet the researcher for assessment. Assessment includes a sleep interview and completing some questionnaires. Participants will then be required to attend 3 group sessions of BBTI across the space of 4 weeks. After attending the BBTI group, participants will be asked to fill in some of the same questionnaires that they filled in during assessment and again 4 weeks later. Participants will also be invited to take part in a focus group to give feedback about the treatment and their overall experience of being in the study.

Detailed Description

This study will explore the feasibility of delivering adapted BBTI in a group setting to family carers of people with dementia. The study will be a feasibility study given that delivering BBTI to groups of dementia carers hasn't been done before. It is therefore necessary to explore, in essence, whether it is 'do-able'. In-line with this, the current study will be considering the following:

  • How many eligible participants consent to participate in the study?
  • How many carers stay in the study until the end?
  • Do carers find BBTI an acceptable treatment, are they able to comply with treatment instructions, and what modifications might be required?
  • Are any improvements in sleep observed?
  • Are any improvements in anxiety, depression and carer burden observed? It is hypothesised that carers' sleep will improve over the course of the study. Specifically, it is hypothesised that there will be a reduction in scores on the Pittsburgh Sleep Quality Index (PSQI), an increase in scores on the Sleep Condition Indicator (SCI), and an improvement in sleep diary parameters (increased sleep efficiency, a reduction in sleep latency and a reduction in wake time after sleep onset) following participation in BBTI. Sleep efficiency is calculated by dividing time spent in bed divided by time actually asleep; sleep latency is the time it takes you to fall asleep and reduction in wake time after sleep onset is the total time you are awake during the night after you first fall asleep. Based on a calculation, the sample size required is estimated to be 11. Given that some participants may withdraw from the study the study will aim to recruit 15 participants.

Procedure Individuals who are caring for a family member with dementia will be given a Participant Invitation Letter by healthcare workers and advertisements will be place in relevant clinics. Those interested in finding out more will make contact with the research team, who will screen potential participants. Those meeting the criteria will be sent a Participant Information Sheet and invited to attend a baseline assessment appointment. At the initial assessment appointment, the researcher will answer any questions the person has about the study, the Participant Information Sheet, or the Consent Form. They will then be asked to fill in the Consent Form before starting the assessment. If they do not consent the assessment will not be initiated. If they do consent, then the researcher will proceed to completing the baseline assessment. This will include the semi-structured sleep interview and questions regarding physical and mental health. The following measures will also be administered: Alcohol Use Disorders Identification Test (AUDIT), Drug Use Disorders Identification Test (DUDIT), Pittsburgh Sleep Quality Index (PSQI), Sleep Condition Indicator (SCI), Hospital Anxiety and Depression Scale (HADS) and the Zarit Burden Interview (ZBI).

Participants will also be shown how to complete a sleep diary at this appointment and will be asked to complete this for the two weeks prior to the first session of BBTI. The baseline assessment appointment is expected to last between 45-60 minutes.

The intervention will be delivered across 3 group sessions and 1 telephone consultation over a period of 4 weeks, as follows:

Week 1 - 90 minute group session (allowing time to cover all the educational material and to give individual sleep instructions as well as a break and initial group introductions) Week 2 - Group session (max 45 mins) Week 3 - Phone call (approx. 15 minutes) Week 4 - Final group session (max 45 mins) Week 5 - Appointments for post-treatment assessment

There will be two group facilitators and groups will have a maximum of 5 participants. Participants will be asked to keep sleep diaries throughout the intervention period. At the beginning of each session, participants will also be asked to complete the Stanford Sleepiness Scale in order to monitor daytime sleepiness.

The following measures will be administered post-treatment and at 4 week follow-up: Pittsburgh Sleep Quality Index (PSQI), Sleep Condition Indicator (SCI), Hospital Anxiety and Depression Scale (HADS) and the Zarit Burden Interview (ZBI).
