Data and analysis scripts for "Anthropomorphic Relational Strategies in AI Companions and Their Implications for Adolescent Emotional Vulnerability: A Cross-Platform Content Analysis"

All datasets and materials underlying a cross-platform content analysis of anthropomorphic relational strategies deployed by five mainstream Chinese AI platforms (two AI-companion apps, three general-purpose assistants) toward adolescents. The package contains: the five raw platform datasets (60 four-turn conversations, 240 AI-generated replies); three coders' independent rating sheets and the adjudication record; the final conversation-level coded dataset (N = 60) for ten behaviour categories and three risk dimensions; the behaviour codebook with original Chinese definitions and matched vignettes; the scenario scripts and collection metadata; the Python analysis scripts; all statistical outputs; and the published figures. Running the included scripts reproduces every number reported in the manuscript. The study involved no human participants and no personal data.
