Epistemic trust refers to the trust in communicated knowledge, specifically an individual's ability to regard knowledge conveyed by others as meaningful, relevant to oneself, and applicable to other contexts. This area has received considerable attention in recent psychological literature, though predominantly from a theoretical perspective. The main objective of this study was to test the factorial validity of the Epistemic Trust, Mistrust, and Credulity Questionnaire (ETMCQ) on an Argentine setting. Based on two studies (Study 1, n = 1018; Study 2, n = 559), the factorial structure of the instrument and its internal consistency were examined (S1 Appendix). In the second study, the factorial structure was confirmed, test-retest reliability was analysed, and associations between epistemic stances and sociodemographic variables, hypomentalisation, attachment styles, childhood traumatic experiences, and anxious-depressive symptomatology were explored. A satisfactory three-factor solution with 15 items and residual correlations was found in both studies, with stable scores over time. Significant positive correlations were found with anxious and fearful-avoidant attachment, hypomentalisation, childhood traumatic experiences, and psychopathological symptomatology. Post-hoc analysis revealed that, on the one hand, gender acts as a moderator in the relationship between hypomentalisation and epistemic mistrust. On the other hand, economic level and educational level moderate the relationship between hypomentalisation and epistemic credulity. Measurement invariance across gender was tested and found satisfactory, with significant differences subsequently observed in the epistemic trust factor. In conclusion, the Argentine version of the ETMCQ provides an empirical measure for use in non-clinical samples. Its application could facilitate clinically and theoretically relevant findings.
