The codebook outlines the methodology for analyzing content from far-right leaders on TikTok during the 2024 European elections, covering the period from May 22 to June 9. Its main objective is to identify patterns and emotional strategies used to attract the vote. The analysis is structured into three dimensions: political party contextualization, leader characteristics on TikTok, and content analysis. Key variables include main themes, predominant emotions, affective polarization, and stylistic techniques. Each category is defined with clear scales, examples, and instructions to ensure a rigorous approach. The training of coders and the use of technological tools ensured the reliability of the analysis, with inter-coder agreement rates exceeding 90%. This code book serves as a transparent methodological guide, enabling a robust and replicable analysis of political impact on TikTok.
