Understanding how children and young people with disabilities perceive their participation is essential for promoting inclusive and person-centred practices. This study investigates how children and youth with Cerebral Palsy (CP) perceive their participation and compares these perspectives with those of their caregivers, using Picture My Participation to analyse attendance and involvement across diverse life contexts. It also examines key activities and identifies perceived facilitators and barriers to participation. Participants included 40 children and young people with CP (5–20 years) and 40 caregivers, all from the Porto Cerebral Palsy Association, Portugal. Results show notable differences in the perceptions of children and their caregivers regarding attendance and involvement. Children and young people most frequently highlighted Celebrations, Playing with Others, and Family Time, while caregivers prioritised Family Time and School. Facilitators included family support, accessibility, and positive attitudes from peers and community members. Barriers were related to Individual Characteristics and Attitudes, which included negative social interactions and perceived exclusion. Caregivers prioritised Individual Characteristics, giving less weight to Attitudes and more to Environmental Context. The study highlights the need to empower children and youth with CP and foster their inclusion by valuing their perspectives.
