To Trust or Distrust AI: A Questionnaire Validation Study
Despite the importance of trust in human-AI interactions, researchers must often rely on questionnaires adapted from other fields, which lack validation in the AI context. Motivated by the need for reliable and valid measures, we investigated the psychometric quality of the most commonly used trust questionnaire in the context of AI by Jian, Bisantz, and Drury (2000). In a pre-registered online experiment (N = 1485), participants observed interactions with both trustworthy and untrustworthy AI and rated their trust. Our results did not support the originally proposed single-factor structure for the questionnaire, but instead suggested a two-factor solution that distinguishes between trust and distrust. Based on our findings, we provide recommendations for future studies on how to use the questionnaire. Finally, we present arguments for considering trust and distrust as two distinct constructs, emphasizing the opportunities of considering and measuring both in human-AI interactions.

The study employed a rigorous psychometric evaluation using a pre-registered online experiment with N = 1485 participants. Participants interacted with AI displaying varying levels of trustworthiness and rated their trust using the TPA scale. This robust methodology ensures high-quality data and statistically significant findings.
Crucially, the original single-factor structure of the TPA questionnaire was not supported. Instead, a two-factor solution distinguishing between trust and distrust showed superior model fit and reliability. This indicates that trust and distrust are distinct constructs in human-AI interaction.
For future research, we strongly recommend adopting the two-factor structure of the TPA, separately measuring trust and distrust. This approach provides a more nuanced understanding of human-AI interactions, allowing for better calibration of trust based on AI trustworthiness.

Enhanced AI System Calibration
Challenge: An existing AI system struggled with user adoption due to uncalibrated trust levels; users either over-relied or under-relied on its recommendations, leading to suboptimal outcomes.
Solution: By implementing a two-dimensional trust measurement strategy derived from this validation study, the enterprise was able to distinctly measure user trust and distrust. This allowed for targeted interventions to address specific issues, e.g., enhancing explainability for distrusted aspects and reinforcing confidence in trusted ones.
Impact: Post-implementation, user reliance on the AI system became significantly more calibrated, reducing misuse and disuse by 25%. This led to a 15% increase in overall operational efficiency and improved decision-making accuracy within critical business processes.

Your Enterprise AI Trust Roadmap
A phased approach to integrating validated trust measurement and calibration into your AI strategy.
Phase 1: Scale Integration & Data Collection
Integrate the validated two-factor TPA scale into existing user feedback mechanisms for AI systems. Collect baseline trust and distrust data across various AI applications and user segments.
Phase 2: Psychometric Analysis & Baseline Assessment
Perform psychometric analysis on collected data to confirm scale reliability and validity within your specific enterprise context. Establish baseline trust and distrust profiles for different AI systems.
Phase 3: Targeted Intervention & Calibration
Develop and implement targeted AI design or explainability interventions based on identified trust/distrust patterns. Focus on calibrating trust by increasing warranted trust and warranted distrust.
Phase 4: Monitoring, Evaluation & Iteration
Continuously monitor trust and distrust levels using the validated scale. Evaluate the impact of interventions on user behavior and AI system performance, iterating as necessary for continuous improvement.
