Providing and connecting family support services to families of young children with developmental delays are part of early intervention services. However, acknowledging the relationships between family support services and family needs based on the perspectives of family stress is critical to enhancing the efficiency of family support services. The main purposes of this research were to explain the influences of characteristics of young children with developmental delays and their families on parents’ perceptions of family stress events, as well as to explore the associations between family stress events and family support service needs. The results indicated that the age and status of young children, the age and education levels of mothers, numbers of children in the family and the total income of the family were significantly associated to parents’ perceptions of family stress events. The perceptions of family stress events were found significantly related to the service needs in terms of parental education and training services, vocational training services, and marriage counseling services. Suggestion on early intervention services were provided from perspectives of family stress.
