Abstract
Objective
The present study introduces and validates the Epistemic Trust Rating System (ETRS), an observer-based measure designed to assess epistemic trust (ET) within psychotherapy. ET in psychotherapy has gained much theoretical attention as a critical component in the therapeutic context, given its inherent link to social communication. However, its empirical validation remains pending, largely due to the absence of a refined instrument to gauge ET levels within the therapy environment. Therefore, this study aimed to translate ET’s theoretical construct into tangible markers within the therapeutic context.
Method
One hundred eighteen patients enrolled in a randomized controlled trial received psychodynamic psychotherapy for depression. Incorporating top-down theoretical considerations with bottom-up empirical observations yielded an overall ETRS score accompanied by three distinct sub-scales, each assessing a singular ET element: one gauges the patient’s propensity to share; another measures the degree to which “we-mode” moments are achieved within the session; and the third evaluates the patient’s receptiveness to learning.
Results
The findings demonstrate the psychometric robustness of the ETRS, with good internal consistency, interrater reliability (ICC(1,8) = .86-.90), and convergent (r = .23-.29) and discriminant validity (r = -.10).
Conclusion
The current study highlights the ETRS as a promising tool bridging theory and empirical exploration, enhancing our understanding of epistemic trust in psychotherapy.
