While there are many benefits to healthy nutrition, adults with intellectual disability often have poor nutrition habits. The purpose of this pilot study was to examine the use of a nutrition app and self- management intervention to increase awareness of healthy nutrition choices for adults with intellectual disability. Data was gathered on the effectiveness of the intervention and social validity of intervention components. Through a single-case multiple-baseline across participants design, the mobile nutrition app with self-management intervention was effective in increasing awareness of healthier nutrition items for three adults with an intellectual disability. Future research is needed to replicate and generalize findings, as well as explore additional supports that may be needed for individuals who have more extensive support needs.
