To solve the problems related to the ageing society, effective strategies to reduce younger people's ageism towards older adults should be developed. Previous studies incorporated the content of stereotype embodiment theory (SET) into ageism reduction strategy, suggesting that younger participants' ageism eventually has undesirable impacts on their own future (i.e., SET intervention). In the SET intervention, participants read an explanatory text on several empirical findings related to SET. To enhance the versatility of this intervention, two experiments were conducted with younger participants in Japan. Study 1 examined concerns that arise in the practical application of the intervention. Results revealed that the SET intervention had few effects on fear of death and increased state self-esteem. In Study 2, the SET intervention was combined with interventions to encourage life planning, in which they freely described possible negative/positive events in their future. SET intervention reduced ageism, increased advocacy for policies to support older adults and increased emphasis on life planning and hope for the future. Many previous studies have shown that intergenerational contact-based interventions are effective in reducing ageism, and future research should be conducted in combination with the SET interventions.
