Background: In 2009, Portugal ratified the UN CRPD and a turn to a rights-based approach in disability law and policy has intensified since. It thus becomes important to understand whether these legal changes are furthering the social inclusion of adults with intellectual and complex disabilities. Method: Questionnaires were applied to a stratified sample of 127 adults with intellectual and complex disabilities attending social care and vocational training programmes across the country. Results: Participants reported low rates of social participation, and many (49%) were found to live below the poverty line. High rates of discrimination and violence and feelings of loneliness and sadness were also reported, which can be strong indicators of the oppression that many of them daily endure. Conclusion: Adults with intellectual and complex disabilities in Portugal face exclusion, discrimination, and violence. The poverty and isolation in which many of them live compounds their (de)citizenship status in Portuguese society.
