Around 95% of Chinese with dementia in Australia and China reside at home and are cared for by family members. The World Health Organization (WHO) iSupport program has been translated into simplified and traditional Chinese and culturally adapted to the Chinese populations in Australia, Mainland China, Taiwan, Hong Kong and Macau. The objective of this study was to explore family caregivers’ experience in a 6-month randomized controlled trial of a facilitator-enabled iSupport intervention program that includes the utilization of the online iSupport and peer support activities.

A qualitative descriptive design was applied to address the study objective. Caregivers’ interactions with peers and program facilitators in monthly online meetings were audio-recorded and transcribed verbatim for data analysis. Facilitators were required to document their support for caregivers in their monthly portfolios and submit for data analysis. Thematic analysis was used to analyse data collected from online caregiver meetings and facilitator portfolios.

Five main themes were identified from data. First, caregivers were able to follow the group learning goal to complete their monthly learning activities using the online iSupport. They were also capable of selecting additional learning units from iSupport to meet their individual learning needs. Second, caregivers perceived that iSupport enabled them to change their responses to changed behaviours their care recipients had by which they reduced the sources of stressor in their daily care. Third, caregivers were willing and felt safe to share their stressors and seek help from peers and facilitators in group meetings. Fourth, caregivers demonstrated their enthusiasm to help their peers reduce their stressors and social isolation by searching and sharing various electronic resources via Wechat or Whatsapp platform throughout the trial. In addition, facilitators were able to assess caregivers’ learning needs and link them with relevant care services and resources accordingly.

Facilitator-enabled iSupport intervention in our study demonstrated advantages of engaging caregivers in learning iSupport, applying knowledge into daily care activities, sharing experiences with and supporting other caregivers.

To investigate dimensions of caregiver burden through factor analysis of the Zarit Burden Interview (ZBI), and to examine predictors of different dimensions of burden.

Confirmatory factor analyses were performed on 395 Hong Kong Chinese Alzheimer caregivers to examine whether several proposed factor structures fit the data well. Subsequently, participants were split into two roughly equal subsamples, for the purpose of identifying the most optimal factor structure through exploratory factor analysis in Sample A (n = 183) and an independent verification through confirmatory factor analysis in Sample B (n = 212). ZBI subscales representing the established factors were correlated with caregiver and care-recipient variables known to be associated with burden.

Confirmatory factor analyses showed that factor models reported elsewhere did not fit the data well. Subsequently, exploratory factor analysis in Sample A suggested a 4-factor structure. After dropping three items due to poor factor loadings, the 4-factor structure was found to fit the data moderately well in Sample B. The four factors tapped personal strain, captivity, self-criticism, and loss of control. However, self-criticism was basically unrelated to the other three factors and showed a rather different pattern of correlations with caregiver and care-recipient variables. Self-criticism was more common among child caregivers and those who did not live with the care-recipient and was less involved in day-to-day care, yet feeling obligated and close to the care-recipient.

The dimensions of caregiver burden may be culturally specific. More research is needed to examine cultural considerations in measuring caregiver burden.
