Background. There is currently a gap in the research literature regarding the occurrence and magnitude of public stigma towards informal caregiving. However, the investigation of stigma towards informal care is highly relevant, given the negative consequences that stigmatization can have. Therefore, this study aims to investigate the public stigma towards informal caregiving for individuals older than 65 years in the German population. Methods. 1038 members of the adult population (18 years and older) living in Germany participated in an online-survey. They were sampled using a quota-system based on the German micro census data. To assess public stigma towards informal caregiving for individuals older than 65 years, the following three aspects of stigma were assessed: 1) emotional reactions (adapted version of the Emotional Reaction to Mental Illness Scale), 2) behavioral reactions (extended version of the Social Distance Scale), and 3) cognitive reactions (newly developed list of Cognitions regarding informal care). Exploratory and confirmatory factor analyses were conducted for the development and adaptation of the three instruments, and their composite reliability is provided. Results. Emotional reactions in terms of devaluing feelings and feelings of misery were low, while appreciative feelings were neither low nor high. Reported social distance was low. Agreement with cognitions towards informal care in terms of devaluing and accusative cognitions was on average low, but high regarding appreciative cognitions. Conclusions. The results show that there is stigma towards informal caregiving for older individuals (65 years and older) in terms of emotional reactions, cognitions and social distance, although the magnitude of this stigma seems to be small. Knowledge regarding the occurrence and magnitude of stigma, as well as the processes that underlie this, is needed to prevent stigmatization and its negative outcomes, or at the very least, to enable the development of support for the affected individuals.
