The aim of the research was to adapt the Dyadic Trust Scale – a tool for studying individuals engaged in close relationships, originally developed by Larzelere and Huston. Trust operationalized as the subjective experience of benevolence and honesty from one’s partner served as the central construct under investigation.

Participants and procedure:
A total of 208 participants involved in emotionally intimate relationships were examined. The successive stages of the re-search procedure related to the verification of the tool for Polish conditions are presented. Evaluation of the psychometric properties encompassed the assessment of both its validity and reliability. The exploratory factor analysis, adopted for the single-factor approach, and confirmatory factor analysis were conducted using SPSS version 28 and SPSS Amos.

The conducted statistical analyses provided evidence for a unidimensional structure consisting of five statements. The mini-mum score that can be obtained by the individual is 5 points, and the maximum is 35 points. The higher the overall score is, the greater is the trust in the dyad. It turned out that the Polish version of the Dyadic Trust Scale is accurate and reliable.

The Dyadic Trust Scale can be used in scientific research investigating trust dynamics within the partners in a dyad. Its use-fulness justifies recognizing trust as crucial for building and maintaining close relationships.
