BACKGROUND: Dementia is considered to be a highly stigmatized condition leading to significant negative effects on the health and well-being of people with dementia and people supporting someone living with dementia. Even though there has been an increasing amount of research on dementia-related stigma over the past two decades, research on effective, evidence-based approaches to reduce dementia-related public stigma is still lacking. METHODS: A 2 × 2 factorial randomized controlled trial (RCT) is being conducted to evaluate the feasibility and short-term efficacy of an online intervention program. It compares different approaches to reduce dementia-related public stigma: 1) Education (ED) that is designed to provide written information on dementia; 2) Contact (CT) that is designed to offer indirect virtual contact with people with dementia and/or people supporting someone with dementia; 3) Education plus contact (ED + CT) that is designed to provide both written information on dementia and indirect virtual contact with people with dementia and/or people supporting someone living with dementia; and 4) an active control condition receiving written information on general health. We aim to recruit 500 lay persons aged 40 and over, to complete a questionnaire measuring the level of dementia-related public stigma, assessed with a modified Attribution Questionnaire and dementia knowledge, assessed with the Dementia Knowledge Assessment Scale version 2 at baseline and follow-up assessments (immediately after the intervention and 12 weeks post-intervention). DISCUSSION: Results from this trial will provide evidence on the most effective approach in reducing dementia-related public stigma. The results are also likely to form an evidence base for the feasibility of dementia-related public stigma campaigns to educate the general public.
