An evidence-based stroke prevention campaign in the Netherlands

INTERVENTION: This study consists of different educational intervention videos, which will be based on the outcomes of a diagnostic survey. The diagnostic survey will be conducted in the first phase of the study, where gaps in awareness of stroke and related to lifestyle factors underlying the risk of stroke are measured. In the second phase, participants are randomised to watch one of our different intervention videos and subsequently will fill out multiple questionnaires. Randomisation will take place via qualtrics.com (questionnaire website). There will be four different intervention videos that will be evenly randomised (1:1:1:1) to the participants of the questionnaire. Thus, in the end the quantity of participants will be evenly distributed between the videos. The intervention videos differ in content. The control (neutral) video consists of educational information to improve awareness and prevention of stroke. The other three videos, which are personality trait‐tailored videos, consist of the content of the control video and segments which are focused on a specific personality (agreeableness, conscientiousness or open‐mindedness). The intervention video with the best performance on improvement in awareness and lifestyle will be scaled‐up and will be distributed via several media outlets focused on the elderly population in the Netherlands. CONDITION: Improving awareness and prevention to reduce the burden of stroke in the general population in the Netherlands ; Circulatory System ; Stroke, not specified as haemorrhage or infarction PRIMARY OUTCOME: ; 1. Understanding the gaps in awareness related to lifestyle factors underlying the risk of stroke, and in relation to different personality traits. This is measured using a questionnaire (diagnostic survey) at baseline.; 2. Definition of the most effective health messaging strategy, tailored to personality traits, to increase awareness of stroke risk factors and to enhance self‐detection of atrial fibrillation, measured using questionnaires before (at baseline) and after showing the different intervention videos.; SECONDARY OUTCOME: ; 1. Self‐reported risk factors for stroke measured using questionnaires before (at baseline) and after showing the intervention video; 2. Identification of high‐risk stroke participants and undetected atrial fibrillation in the research population using questionnaires before (at baseline) and after showing the intervention video; INCLUSION CRITERIA: Aged 18 years and older
