Intergenerational interventions have traditionally focused on cognitively healthy older adults or those with dementia, with no known studies specifically targeting older adults with Subjective Cognitive Decline (SCD). This study aimed to evaluate the effects of an intergenerational intervention involving both children and older adults with SCD, who participated as "teachers." Twenty-eight retired teachers were divided into three groups: (a) an experimental group, (b) a control group participating in other cognitive training programs, and (c) a control group with no intervention. All participants were affiliated with the Greek Association of Alzheimer’s Disease and Related Disorders in Thessaloniki, Greece. Additionally, eighteen 7-year-old students were assigned to either an experimental or a control group. Neuropsychological assessments were administered to the older adults, while the children completed tests measuring verbal and non-verbal intelligence. Quantitative results showed that children in the experimental group demonstrated improvements in reading, vocabulary, and mathematical skills. Older adults in the intervention group showed enhanced everyday functional abilities. Qualitative data further revealed a positive emotional response to the program in both age groups. In conclusion, intergenerational interventions appear promising for improving cognitive and functional outcomes in older adults with SCD and cognitive development in young children, while also strengthening intergenerational bonds, promoting mutual understanding, and fostering emotional engagement with the program.
