Background Across countries, most dementia carers report a lack of adequate information about dementia and local services. To address this issue, the World Health Organization developed the iSupport programme to provide information and support to dementia carers. The iSupport online programme was found to be feasible and acceptable by dementia carers. However, the potential of using the iSupport manual (iSupport) specifically for Chinese dementia carers in New Zealand remains unknown. Objective This study aimed to (1) identify refinements to adapt iSupport by eliciting the perspectives of Chinese dementia carers; and (2) explore the educational needs of Chinese dementia carers, which can inform the development of support programmes tailored to their specific requirements. Design This was a qualitative descriptive study using semistructured interviews. The data were analysed using thematic analysis. Results Twelve Chinese dementia carers were interviewed (mean age 58.0 years, 100% female, and mean caring experience of 2.2 years). Emerging themes were identified within three domains: (1) usefulness, (2) complexities of using iSupport, and (3) suggestions for improvement. Conclusions The findings suggest that Chinese dementia carers generally found iSupport to be valuable, providing valuable insights into how to tailor and enhance support for this population. However, further research is required to empirically validate the effectiveness of the adapted iSupport for Chinese dementia carers in New Zealand. These findings have implications for the development of future interventions that can more effectively address the specific needs of Chinese dementia carers.
