Do communication interventions affect the quality-of-life of people with dementia and their families? A systematic review

The effects of a facilitator-enabled online multicomponent iSupport for dementia programme: A multicentre randomised controlled trial

BACKGROUND

Multicomponent interventions with carers of people with dementia demonstrate positive effects on the health and quality of life for carers and care recipients. The World Health Organization's iSupport for Dementia is an evidence-based online psychoeducation programme for carers. However, the programme was mainly implemented as a self-learning tool which might have limited its positive effects on carers and care recipients. Evidence for online multicomponent interventions with carers that incorporates the iSupport programme remains unknown.

OBJECTIVES

This study aimed to partner with health and social care organisations to evaluate the effects of a facilitator-enabled online multicomponent Chinese iSupport programme, which included psychoeducation using the iSupport programme, facilitator-enabled carer support groups and access to care services.

DESIGN

A multicentre randomised controlled trial.

SETTINGS AND PARTICIPANTS

Participants were family carers in Australia and greater China. We recruited participants to the study from 1st November 2021 to 30th June 2022.

METHODS

The intervention group received the Chinese iSupport programme delivered online. The intervention lasted for 6 months. Our primary outcome was carers' quality of life. Our secondary outcomes were carers' self-efficacy, social support, distress reactions to changed behaviours, care recipients' frequency of changed behaviours, quality of life, unplanned hospital admissions, emergency department presentations and permanent admissions to nursing homes. The outcomes were measured at baseline (T0), 6 months (T1) and 9 months (T2). We applied a multivariate mixed effect linear regression model to capture the group effect, time effect and their interaction.

RESULTS

In total, 266 eligible family carers agreed to participate and were randomly assigned to an intervention group (n = 131) or a usual care group (n = 135). Most carers were women with a mean age of 53 years. The intervention group showed a statistically significant higher score of mental-health-related quality of life (mean difference = 4.1, 95 % CI: 1.5, 6.8, p = 0.002), self-efficacy in controlling upsetting thoughts (mean difference = 7.1, 95 % CI: 2.2, 12.0, p = 0.005) and lower score of distress reactions to changed behaviours (mean difference = -0.1, 95 % CI: -0.3, -0.03, p = 0.012) than the usual care group at T1.

CONCLUSION

The facilitator-enabled online multicomponent Chinese iSupport programme demonstrated positive effects for carers on mental health-related quality of life, controlling upsetting thoughts and distress reactions to changed behaviours of people with dementia.

TRIAL REGISTRATION

This study is registered in the Australia New Zealand Clinical Trials Registry on 12th March 2021 (ACTRN12621000276853).

TWEETABLE ABSTRACT

The facilitator-enabled online multicomponent Chinese iSupport programme improved family carers' mental health-related quality of life, control of upsetting thoughts and distress reactions to changed behaviours of people with dementia.

The Relevance of Communication Between Alzheimer's Patients and Their Caregivers. Effective Prosody Strategies to Improve Communication

One of the most critical factors in Alzheimer's disease (AD) is communication between patients and caregivers. A relevant part of the way of speaking is what is known as prosody, or the variations a speaker makes when talking. To our knowledge, no research has analyzed the relevance of communication for caregivers when speaking with AD patients or what they consider the most effective strategies to communicate with them. Therefore, this pilot study aims are twofold: to know the relevance caregivers (professionals and family) give to communication with AD patients; and to determine what prosody strategies they consider most effective. Two hundred fifty-two caregivers of AD patients (professional and family) participated in two online surveys, answering different questions about the relevance of communication and the best prosody strategies. They also performed an auditory perceptual assessment. The results showed that caregivers give communication a significant role in the patient's treatment behavior. They consider Alzheimer's (AD) patients should be spoken to with authority but with affection and positiveness. The most valued prosodic strategies were marked intonation, speaking affectionately, emphasizing essential words, a medium/low pitch, and a slow speed. This study highlights the value of communication in interacting with AD patients to improve their cognitive and emotional responses.
