Objectives: This study aimed to investigate the association between familiarity with caregiving and public stigma towards informal caregivers of older individuals. Material and methods: The sample for this Online-Survey was identified using a quota-system based on German micro census data (N=1037; aged 18 years and older, living in Germany). Familiarity with caregiving was assessed by asking whether the participant has experience in or has friends or relatives with experience in informal or professional caregiving for individuals aged 65 years or older.
