Cross-Cultural Adaptation and Psychometric Validation of the Chinese Version of the Perceived Shared Understanding with AI (PSU-AI) Scale

Data were collected via online questionnaire using the Jianshu platform. Data were collected via two independent survey rounds with non‑overlapping participants.In the first round, participants responded to the preliminary 8‑item Chinese PSU‑AI scale (PSU1‑8). The first‑round dataset was used for item analysis and exploratory factor analysis (EFA), to examine the factor structure and evaluate the psychometric performance of each item. In the second round of data collection, a new independent sample was recruited. Besides the 8‑item PSU‑AI scale (PSU1‑8), participants also completed the AI Response Satisfaction Scale (Q1‑6) and Trust in the AI Scale (Q1‑6). The second‑round dataset was applied to conduct confirmatory factor analysis (CFA) for PSU‑AI, AI Response Satisfaction Scale and Trust in the AI Scale. Moreover, Pearson correlation analyses were performed between PSU‑AI, the Inclusion of Other in the Self scale (IOS), AI Response Satisfaction, and Trust in the AI Scale to test convergent validity.
