This paper presents the results of a qualitative study conducted with older people attending Czech Universities of the Third Age (U3A). The paper aims to identify and describe the role of family and close individuals in helping older people deal with disinformation. Data were collected through 11 focus groups with older people. Participants worked with prepared materials that served as a basis for discussions. The data analysis was carried out using thematic analysis. After repeated readings of the transcripts, the open coding method was applied. Codes were then grouped to identify preliminary (sub)themes. Five main themes emerged: reactions to disinformation, strategies for dealing with disinformation, factors contributing to recognising (un)reliable information, environment, and (non)sharing of news. Intergenerational support in managing disinformation appeared in each of these themes.

The research focusing on intergenerational support in managing disinformation from the perspective of older people revealed the positive role of family (children, grandchildren) and close individuals. Older people often rely on their advice to recognise disinformation and avoid the risk of succumbing to manipulation, such as financial offers. The help of family members gives them a sense of security. The family also plays a crucial role in preventive warning about the dangers associated with disinformation. Repeated reminders of basic principles (such as not trusting seemingly advantageous offers or not allowing unknown people into their homes) are among the key mechanisms for minimising risks associated with manipulation. However, the results also indicate the frequent failure of this intergenerational learning. Despite their families' warnings, older people trust unsubstantiated information, especially concerning their health.

Another research finding is that ineffective intergenerational learning could negatively affect older people and their families. Family members often have to deal with the consequences of hasty decisions made by seniors, such as complications in withdrawing from unfavourable contracts. Consequently, family members find themselves in the role of advisors and as a safety net trying to mitigate the consequences of older people's decisions. This situation is exacerbated by the fact that older people who live alone are even more at risk of succumbing to disinformation. One reason for this may be a sense of loneliness and limited social contact with close individuals. Therefore, regular contact with family is crucial. The data suggests the need to create and focus programs on developing information and data literacy among older people and supporting intergenerational communication and learning.
