Aim: To explore the use ofthe Ecological Validity Model as a guiding framework in the provision of a culturally-sensitive assistive technology (AT) intervention for community older people. Methods: Twenty-seven Hispanic adultsaged 70 years and older, and four individuals with expertisein AT participated in a concurrent nested mixed method study where the quantitative method (content validity ratio exercise) was embedded in the dominant qualitative method (focus groups). Results: Findings informedthe development of the Assistive Technology Life Enhancement Program (ATLEP); an intervention consisting of seven modules addressing AT devices with culturally sensitive elements. Conclusions: The Ecological Validity Model, as well as, the input from older adults were both effective methodological strategies in tailoring the ATLEP intervention to the needs and circumstances of community-living older people living in Puerto Rico.
