The aging process is characterized by diverse and complex changes in the individual’s various dimensions, requiring continuous adaptation. In this sense, this transition can be faced from an active aging standpoint through strategies such as intergenerationality programs/projects, resulting in an active social participation and valorization that is so important to life in society. This review aimed to map existing programs/projects to promote interaction between children and older adults in Portugal to understand the extent and type of evidence available. A scoping review was developed guided by the JBI methodology and using PRISMA-ScR. The studies included six programs/projects promoting intergenerationality identified in Portugal, focusing their actions on promoting active aging and preventing problems associated with aging. The evaluated dimensions along the implementation of these programs were in the cognitive, motor, emotional and communicational domains, including parameters such as self-esteem, self-confidence, self-worth, well-being, loneliness and depression. These programs/projects present themselves as potential senior mental health promoters. However, other dimensions have been evaluated during these programs’/projects’ applications.
