Objective: The objective of this study was to investigate the attitudes towards choice architectural nudge interventions aiming to increase vegetable intake among Danish teenagers in a school context, and which factors influence these attitudes.Methodology: Cross-sectional data were collected through an online quantitative questionnaire, which was developed, validated and distributed to assess factors associated with attitude towards choice architectural nudge interventions. Data analysis included descriptive statistics, factor analysis and structural equation modelling. A total of 408 respondents (78% female) with a mean age of 18(±1.3) spread throughout Denmark provided sufficient responses.Results: The structural equation model revealed that healthy buffet ha- bits and opinions of where the responsibility of healthy eating lies had the strongest positive association with attitude towards choice architectural nudge interventions. Also, social norms were positively associated with the outcome. Perceived vegetable intake and buffet habits attaching importance to animal welfare and organic food had a negative association.The descriptive analysis found that the respondents were generally positive towards less intrusive nudges and displayed a more negative attitude towards those targeting their self-image. Further, the respondents considered it to be acceptable for the school to attempt to intervene with their health-related behaviour, but essentially they saw it as neither the school's obligation nor responsibility.Key findings: Healthy buffet habits and opinions of where the responsibility of healthy eating lies were found to have the strongest positive association with attitude towards choice architectural nudge interventions. In general, the respondents were predominantly positive towards the use of less intrusive choice architectural nudge interventions, while negative attitudes were expressed towards nudges targeting the respondents' self-image
