Brief Summary:
Dementia is irreversible incurable and devastating It is thus imperative to preserve cognition at the pre-dementia stage Mild cognitive impairment MCI refers to the reversible intermediate clinical state between normal age-related cognitive decline and dementia Because no pharmacological treatments have proved to be effective risk factor modification remains the cornerstone in preventing progression from MCI to dementia Insomnia is an emerging risk factor now being associated with cognitive decline and it affects up to 59 of persons with MCI Compelling evidence shows that sleep is vital for memory consolidation and it mediates the deposition of amyloid-β and tau proteins in the brain Despite these findings minimal research has done to evaluate sleep-promoting interventions on the cognitive function of persons with MCI Non-pharmacological interventions remain the treatment of choice for managing insomnia particularly the older population These interventions require individuals to actively participate in the treatment process Yet the cognitive impairment and neuropsychiatric symptoms in persons with MCI create challenges for them An empowerment approach with interactive teaching strategies and experiential learning may be the best method of engaging people in the learning process and arousing their inherent capacity to maintain behavioral modifications This study aims to examine the feasibility and preliminary effects of an empowerment-based cognitive behavioral therapy for insomnia CBT-I in persons with MCI and sleep problems The researchers will compare the effects of this intervention by comparing with the standard care
Detailed Description:
The proposed study will have two aims i to determine the feasibility of an empowerment-based CBT-I in MCI persons and ii to examine the preliminary effects of the empowerment-based CBT-I on sleep cognitive outcomes and HRQoL in persons with MCI
Study design This is a mixed-method study with a single-blinded parallel-group randomized controlled trial RCT and a qualitative study to determine the feasibility and preliminary effects of the empowerment-based CBT-I on sleep cognitive outcomes and HRQoL in persons with MCI Eligible participants will be recruited from the elderly community centers operated by two non-governmental organizations in Hong Kong After collecting the baseline data T0 participants will be randomly assigned into the intervention group and control group with block randomization to ensure even distribution of participants in the two study groups over the study period A computer-generated random sequence will be used to determine the block size 6 8 and 10 and respective study group allocation in a 11 ratio To ensure allocation concealment the group allocation will be determined according to the random sequence codes placed in sealed opaque envelopes Participants in the intervention group will receive the empowerment-based CBT-I whereas the control group will receive usual care provided by the community centers A total of 60 participants ie 30study arm will be recruited for this pilot RCT Upon completion of the RCT ten participants in the intervention group will be invited to have an individual qualitative interview to gather their in-depth comments about the feasibility and acceptability of the empowerment-based CBT-T intervention The collected information will be used to optimize the procedures and process of the future main study To reduce contamination of the control group the intervention sessions will be delivered in a private room of the study sites The participants in the intervention group will be advised not to share the content with other members in the centers Nonetheless the active ingredients of the intervention are the intensive interactions between the intervener and the participants which is less likely to be replicated and disclosed by the participants
Study Interventions Intervention group Empowerment-based CBT-I for MCI Participants in the intervention group will participate in a 12-week empowerment-based CBT-I comprising face-to-face sessions supplemented with telephone follow-ups In total six face-to-face sessions 90 minutessession will be conducted in a small group format with 6-8 participants in a group and two 30-minute individual sessions will be scheduled over eight weeks with the individual sessions arranged in the 4th and 7th week and this is then followed by two bi-weekly telephone follow-ups The face-to-face sessions will cover the following core areas in CBT-I i sleep education ii sleep hygiene and relaxation iii sleep restriction iv stimulus control and v cognitive therapy The first five sessions will cover these core areas and a booster session will then follow to summarize the key components of CBT-I and equip the participants with relapse-prevention strategies when sleeping problems recur The content of the CBT-I components complies with the recommendations for managing chronic insomnia by major international sleep associations
A five-step empowerment approach will be adopted to implement each face-to-face session to facilitate goal attainment and behavioral maintenance At the beginning of each session the intervener will encourage the participants to discuss their usual practice or beliefs about sleep or insomnia related to the core area of that week then deliver a structured educational session about the topic area The rationales and explicit methods of how to carry out the suggested behaviors will be stated The content will emphasize assisting participants to understand the linkage between their usual practice behaviorsthoughts and the consequences to sleep disruption The intervener will then facilitate the participants to identify the discrepancies between their usual practicedysfunctional beliefs and the recommended best practice for sleep improvementbeliefs that favor better sleep Easy-to-understand comic stories will be incorporated to illustrate the more abstract concepts about dysfunctional beliefs related to insomnia for the session on cognitive therapy and bed-sleep association for the session on stimulus control The intervener will also highlight the possible consequences of these discrepancies on brain health The intervener will then assist participants to set self-directed goals related to these areas During this process the intervener will work collaboratively with the participants and ensure that the goals are achievable yet challenging The intervener will also work with the participants to develop an action plan for achieving the goals set during each session After action-planning a subsequent interactive skill-building session will ensure that participants acquire the skills required to perform specific behaviors A scenario-based approach will be adopted to train the participants on how to maintain the recommended behaviors The intervener will make use of group dynamics by encouraging the discussion among the peers of successful actions feelings concerns and perceived barriers to goal achievement Various memory compensatory strategies will be used to reinforce the educational content such as memory aids eg memory notebooks calendars and to-do lists and mnemonic strategies Each subsequent session will begin with a discussion of progress in goal attainment and challenges and barriers encountered while implementing the action plan set during the preceding week
The intervener will provide continuous support through individualized one-to-one face-to-face meetings 7th and 9th week and telephone calls three bi-weekly calls on 8th 10th and 12th week upon the completion of all the group-based sessions A personal record containing the participants demographic and clinical profile endorsed dysfunctional beliefs and attitudes about sleep self-directed goals and action plans will be created to facilitate the individualized face-to-face sessions and telephone support The intervener will monitor participants adherence to the recommended behaviors and goal attainment progress identify barriers in real-life settings and provide methods of resolving them The advice and counseling given will be documented to guide subsequent telephone calls
Control group Usual care The control group will not receive any structured cognitive training or sleep promoting interventions during the study period The participants in the control group will continue to participate in the social activities offered by the elderly community centers They have access to the newspapers board games and computer facility in the centers
