In Quebec, families with children with intellectual disabilities (ID) or an autism spectrum disorder (ASD) of all ages continue to have a high need for respite services. In order to meet their needs, Quebec City partners have developed a service offer model designed for these families based on the involvement of Université Laval health care and social service students. The opinions of parents and students were collected using online questionnaires (106 students and 87 parents). The majority of respondents expressed interest in offering or receiving such services. Students wish their involvement to be paid, flexible, and with families living close to their homes. Parents need access to a stable and continuous service offer. They would like increased financial support for the associated expenses. The data presented in this article will contribute to the development of a service model that is tailored to the needs of families with children with ID or ASD while improving future professionals’ theoretical and practical training.
