Objectives: The objective was to investigate the performance aspect of participation, operationalized as the frequency of occurrence of family activities and child presence in these activities for children with profound intellectual and multiple disabilities (PIMD) and children with typical development (TD). The focus was also on how family and child characteristics are related to the frequency of occurrence of family activities. This is part of a larger research project investigating facilitating factors for participation in children with PIMD. Methods: A descriptive, comparative study was performed using a questionnaire developed for the purpose. Results: In the families with a child with PIMD, the majority of activities occurred less often than in families with children with TD. In both groups, relationships were found between the frequency of occurrence of family activities and total family income, as well as the educational level of the parents. For children with PIMD, motor ability, cognition, health, and behaviour, were related to frequency of occurrence. Moreover, the presence of the children in the activities differed in the two groups; the children with PIMD were present in the activities less often. Discussion: Considering a long-term perspective, low occurrence of family activities and child presence may affect child development and everyday functioning. Knowledge about factors related to the occurrence of family activities and child presence in them, as well as an understanding of its causes, can promote the provision of everyday natural learning opportunities for children with PIMD.
