The exchange of support between generations is a fundamental feature of intergenerational relationships. While most studies have concentrated on the impact of social support on the receiver, effects on subjective well-being of the provider of support have been studied less often. Given cultural differences in the norms and values of intergenerational relationships, the present study compared samples from rural and urban China, Indonesia, and Germany. The results showed that in the different cultural contexts elderly mothers well-being was differently related to help which they provided to their adult daughters. The results are discussed from a culture-informed perspective on intergenerational relationships.
