Objective The purpose of this study was to examine the impact of being exposed to a multimedia campaign on stigmatic beliefs towards a person with Alzheimer's disease (AD). Methods A cross‐sectional posttest online survey was conducted immediately after the campaign among 510 Jewish participants aged 40 and above. Results Most the participants reported being exposed to the campaign. The campaign elicited significantly higher positive than negative emotions. Exposure to the campaign was not significantly associated with any of the stigmatic beliefs as a direct or moderating variable. Worry about developing AD was associated with increased stigmatic beliefs. Conclusions More research is needed to better understand which types of media campaigns work best to increase awareness and reduce stigma associated with AD.
