Devan Rays Donaldson has self-archived "Development of a Scale for Measuring Perceptions of Trustworthiness for Digitized Archival Documents."
Here's an excerpt:
This dissertation advances scholarship on trustworthiness in three ways. First, it revises an existing conceptual model for trustworthiness perception. Second, it creates an original measurement model for digitized archival document trustworthiness perception-the Digitized Archival Document Trustworthiness Scale (DADTS). Third, it contributes to a deeper understanding of the concept of trustworthiness by providing measurement of the concept in a way that is sensitive to its nuances.
