Free access. There has been an increasing interest in establishing dementia friendly communities leading to the development and delivery of various dementia awareness initiatives. These initiatives have generally been aimed at adults; however, to sustain dementia friendly communities, the involvement of young people is imperative. Very few dementia awareness initiatives exist for young people, and none have been independently evaluated to establish their impact. This research aimed to design and develop a scale to measure adolescents' attitudes towards dementia to allow such initiatives to be evaluated.
