Telephone-Coached Sleep Bibliotherapy for Informal Caregivers of People With Dementia: A Randomized Controlled Trial

Sleep disturbances are common among informal caregivers of people with dementia and can negatively affect their physical and psychological well-being. This randomized controlled trial aims to evaluate the effectiveness of an 8-week telephone-coached sleep bibliotherapy program in improving sleep quality among informal caregivers of people with dementia. Participants will be randomly assigned to either a sleep bibliotherapy intervention group or an educational booklet control group. Outcomes including sleep quality, caregiving appraisal, dysfunctional beliefs about sleep, emotional distress, neuropsychiatric symptoms of care recipients, and quality of life will be assessed at baseline, immediately post-intervention, and 3 months post-intervention.

Study Overview

Detailed Description

This study is a two-arm randomized controlled trial designed to evaluate the effectiveness of telephone-coached sleep bibliotherapy for informal caregivers of people with dementia.

A total of 120 eligible caregivers will be recruited and randomly assigned to either the intervention group or the control group. The intervention group will receive an 8-week telephone-coached sleep bibliotherapy program.

The control group will receive an educational booklet containing general health information and weekly check-in calls. Both groups will continue receiving usual community services.

Data will be collected at baseline, immediately after the intervention, and 3 months after the intervention. The primary outcome is sleep quality measured using the Pittsburgh Sleep Quality Index (PSQI). Secondary outcomes include caregiving appraisal, dysfunctional beliefs and attitudes about sleep, emotional distress, neuropsyatric symptoms of care recipients, and quality of life.

The findings will provide evidence regarding the effectiveness of a low-cost and easily disseminated intervention for improving sleep and well-being among caregivers of people with dementia.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Sleep Quality
Time Frame: Baseline, immediately post-intervention (8 weeks), and 3 months post-intervention
Sleep quality will be assessed using the Pittsburgh Sleep Quality Index (PSQI). Higher scores indicate poorer sleep quality.
Baseline, immediately post-intervention (8 weeks), and 3 months post-intervention

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Caregiving Appraisal
Time Frame: Baseline, immediately post-intervention (8 weeks), and 3 months post-intervention
The Chinese version of the Caregiving Appraisal Scale will be used. This is a 5-point Likert scale with 26 items and four subscales (caregiving satisfaction, caregiving mastery, subjective caregiving burden, and caregiving impact).
Baseline, immediately post-intervention (8 weeks), and 3 months post-intervention
Dysfunctional beliefs and attitudes about sleep
Time Frame: Baseline, immediately post-intervention (8 weeks), and 3 months post-intervention
It will be measured using the Chinse version of 16-item Dysfunctional Beliefs and Attitudes about Sleep scale (DBAS-16). DBAS-16 is a 16-item scale.
Baseline, immediately post-intervention (8 weeks), and 3 months post-intervention
Emotional distress
Time Frame: Baseline, immediately post-intervention (8 weeks), and 3 months post-intervention
It will be measured with the stress, anxiety, and depression scales (DASS-21).
Baseline, immediately post-intervention (8 weeks), and 3 months post-intervention
Patient neuropsychiatric symptoms
Time Frame: Baseline, immediately post-intervention (8 weeks), and 3 months post-intervention
The Neuropsychiatric Inventory (NPI) will be used to measure neuropsychiatric symptoms. NPI evaluates 12 common neuropsychiatric disturbances in dementia.
Baseline, immediately post-intervention (8 weeks), and 3 months post-intervention
Dyadic quality of life
Time Frame: Baseline, immediately post-intervention (8 weeks), and 3 months post-intervention
It will be measured with the Quality of Life-Alzheimer's Disease Scale (QOL-AD), which will be separately rated by caregivers and care recipients. It is a 13-item, 4-point Likert scale that measures the quality of life for adults w
