This study is premised on the notion that intervention programmes aimed at improving children's well‐being should be inclusive of activities which promote children's self‐concept. Using a child participation framework, this study aimed to explore children's perceptions of the nature and content of intervention programmes aimed at improving children's self‐concept within two impoverished communities of the Western Cape, South Africa. The Delphi technique was followed with a group of 10 children between the ages of 10 and 12 years who were considered to be knowledgeable experts and authorities on matters affecting their lives and well‐being of children. They suggested that intervention programmes include a focus on safety, the provision of social support, the creation of opportunities for learning and for play and the provision of basic material needs.
