We tested this assumption by conducting a survey among people living in a least developed country compared with those living in a developed country.Participants and methods: Twenty-seven Belgians living in Belgium, 29 Burundians living in Belgium, and 32 Burundians living in Burundi were included in this study. Their attitudes toward older adults were assessed using several self-reported measures.Results: Statistical analyses confirmed that older people are more negatively perceived by Burundians living in Burundi than by Burundians and Belgians living in Belgium, whose attitudes did not differ from each other.Conclusion: Consistent with our hypothesis, our results suggest that the level of development of a country and more particularly the lack of government spending on older people (pension and health care systems) may contribute to their younger counterparts perceiving them more negatively. Keywords: attitudes toward older adults, cross-cultural differences, socioeconomic development, intergenerational relations
