the concept that people with mental or physical disability should not be denied social and sexual relationships and participation in community life merely because of their disability. Social and sexual relationships can include a wide range of emotional and physical contacts, from simple friendship to sexual stimulation and satisfaction. Participation in community life includes engaging in typical everyday activities, such as work and recreation. See also social role valorization. [introduced in 1969 by Swedish psychologist Bengt Nirje (1924–2006)]
