Survey and Experimental Data on AI Companion Psychological Ownership

An online appendix contains survey and experimental data from studies on psychological ownership of AI companions like Replika. The 13.7 MB PDF includes datasets, survey items, and statistical results from a pilot study and two experiments. It was authored by Dominik Siemon and last updated in April 2026.

Use Cases

• Analyze correlations between survey constructs like perceived affordances and psychological ownership scores.
• Apply the provided structural equation modeling results to validate theoretical models of AI attachment.
• Replicate ANOVA and ANCOVA tests on experimental data comparing user groups.
• Use the documented semantic textual similarity methods for analyzing open-ended survey responses.
• Benchmark construct reliability metrics (e.g., Cronbach's alpha) from the pilot study against new data.

Strengths

• Includes data from a pilot study and two controlled experiments, providing multiple validation points.
• Documentation covers full methodological pipeline from data sampling to advanced neural topic modeling.
• Released under a permissive CC-BY-4.0 license for clear reuse.

Limitations

• Primary data is embedded within a 13.7 MB PDF, requiring extraction for computational analysis.
• Sample sizes for the pilot and experiments are not specified in the provided description.
• The dataset is static and tied to a specific research paper, limiting temporal relevance.
