Appendix I: Advertisement Categories and Financial-Themed Video Ads Transcription

This file contains the full questionnaire used in a study on young people's understanding of personalized advertising on social media. The questionnaire includes two main sections: (1) a list of advertisement categories for participants to indicate which types they commonly see on their TikTok and Instagram accounts, and (2) a series of transcriptions of financial-themed video ads. Participants were asked to rate how likely it was that similar ads would appear on their personal social media feeds.This material served as part of a broader research project on advertising literacy and perceived targeting among young people. The study received ethical approval from the university's research ethics committee, and all data collection adhered to GDPR regulations. The materials uploaded here are intended to promote transparency and enable future replication or comparison across studies on digital advertising and audience perception.
