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. Results 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.
