Description

Proposed Study:

The investigators propose a 6-week randomized controlled trial to compare the effectiveness of a novel online self-help intervention for caregivers of older adults in Hong Kong. The intervention is based on Cognitive Behavioral Therapy, lifestyle intervention, and effective communication skills.

Randomization

The research team will perform individual randomization using statistical software R. Randomization will be using random permuted blocks via an online computer randomization system from an independent clinical trials unit. Participants will be randomized into two intervention groups or control group.

Outcomes

The primary objective of this study is to evaluate the effectiveness of an online self-help eCoaching intervention that incorporates symptom management, stress management, and coping skills training in promoting healthy behavior change among caregivers. Additionally, this study aims to investigate the effectiveness of the online self-help eCoaching intervention in reducing carers' depressive symptoms and anxiety. Another key objective is to enhance carers' self-efficacy for stress management and resilience by equipping them with the necessary skills and strategies provided through the eCoaching intervention.

Recruitment and Inclusion Criteria:

A total of 232 caregivers from seven district-based caregiver support units will be recruited. The inclusion criteria are as follows: 1) Participants must be adults aged 18 or above with a family member aged 60 or above requiring caregiving, providing at least 6 hours of care per week; 2) They must self-identify as a family caregiver; 3) Participants must live in Hong Kong and 4) be able to communicate with the interventionist; 5) Participation must be voluntary; 6) Additionally, participants must report mild need in the Carer multidimensional Need Assessment tool. The exclusion criteria include: 1) having diagnosed Alzheimer's or other dementia; or 2) experiencing acute health conditions that hinder caregiving support or intervention participation.

Study Procedures:

This study will consist of a 6-week intervention, with a screening process to be conducted prior to the intervention implementation. Baseline and immediately after the intervention, as well as a 3-month follow-up assessment, will be performed for statistical comparison. The participation of caregivers in tests, surveys, and interviews will not affect the quality of care they receive. No drug usage or medical treatment is involved in this study, and there are no anticipated physical or medical risks to participants. Withdrawal from the study is voluntary at any time, and will not impact participants' ongoing medical care or legal rights.

The screening process involves carers completing a standardized screening form comprising items pertaining to demographics, self-efficacy, caregiving preparedness, and willingness to join, which they will either fill out independently or have facilitated by project staff upon enrolling for membership. Carers' needs are classified into four levels: low, mild, moderate, and high.

The Carer Multidimensional Need Assessment Tool was developed and validated by the research team of the Jockey Club Carer Space Project, which was led by Professor Vivian Lou, the Director of the Sau Po Centre on Ageing at the University of Hong Kong. The research centre followed a six-step approach, based on the scale development method proposed by Hinkin (1995), to establish the Carer Need Screening Tool. These steps encompassed: (1) a literature review, (2) the formation of an expert panel, (3) a Delphi study, (4) the confirmation of an item list, (5) an item validation study, and (6) the finalization of the scale. The research team developed a 22-item screening tool, and the screening tool involves 5 domains of risk including carers' mental ill health, caregiving capacity, lack of support, carers' health challenges, and high care demands.

Data Analysis:

A MANOVA will be conducted for the continuous variables and a chi-square test will be used for the categorical variables, to compare the differences between the primary and secondary outcomes of the three groups. The associations among different variables will be investigated using Pearson's correlation analysis. The interaction Group x Time treatment effects within and between the groups (eCoaching I, eCoaching II, Control) will be tested with a factorial ANOVA with repeated measures. Differential changes in each outcome across the 3 assessment time points (T0, T1, T2) between the three treatment groups will be compared. Recruitment rate, attrition rate, and missing data will also be examined and reported. All outcome measures will be analysed based on intention-to-treat principles. Exploratory analysis will assess whether the intervention effects are mediated by caregiver self-efficacy or knowledge gain. The data will be analysed using SPSS, version 28.0. All statistical tests will be two-sided with the level of significance set at .05.

Data Storage and Privacy:

Personal data will be securely stored by the principal investigator for 5 years after the publication of the first paper, followed by 10 years for anonymized data. All information will be used for research purposes only and stored on encrypted workstations and password-protected online cloud storage.
