People with intellectual disabilities require training to improve independence, and carers are important partners in the process. Studies show that carers are able to motivate family members with intellectual disabilities to participate in training. In addition, family members may serve as cotrainers. To increase carers' participation, it is necessary to empower them with training techniques and develop strategies to relieve their stress. This article aims to explore the effects of carer support to enhance training quality of daily living skills for their family member with intellectual disabilities, through the use of care case studies, in the context of families living in Hong Kong. A model of multiple case studies is adopted. Three cases are analyzed to illustrate various modes of carer participation.
