How epistemic trust, mistrust and credulity relate to mental health, personality pathology, treatment engagement and relationship in psychotherapeutic and psychiatric settings.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundEpistemic trust describes the capacity to appropriately identify others as reliable and relevant sources of information, an ability closely linked to attachment and social learning. Epistemic disruption can manifest as heightened suspicion (mistrust) or excessive reliance (credulity) vis-à-vis others, affecting mentalizing abilities and increasing vulnerability to psychopathology and maladaptive traits. These interdependent and multidirectional dynamics are pivotal to therapeutic learning, and thus to therapeutic change.
objectiveThis study examined associations between epistemic trust and disruption, markers of psychopathology, therapeutic relationship quality and treatment-seeking behaviour.
methodA naturalistic sample of 912 participants, recruited via a mental health app, completed the Epistemic Trust, Mistrust and Credulity Questionnaire, along with self-reports capturing internalising symptoms, personality functioning, maladaptive traits and the perceived therapeutic relationship within the previous 6 months. Treatment-seeking behaviour and the number of sessions utilized in the past year were further explored-both in psychotherapeutic and psychiatric contexts.
findingsEpistemic mistrust and credulity showed consistent relationships with markers of psychopathology. Higher epistemic (mis)trust correlated with more positive (negative) ratings of various aspects of the therapeutic relationship, including genuineness, realism, expectations, congruence and responsivity-over the past 6 months. Epistemic trust positively predicted the amount of psychotherapy sessions, while epistemic mistrust negatively predicted treatment-seeking, both controlled for personality dysfunction. Epistemic credulity predicted mental health app use-all assessed retrospectively (past year).
conclusionThe results encourage further in-depth exploration of trust-related aspects of the therapeutic alliance and investigation of mechanisms of change in therapeutic processes that may facilitate the transition from mistrust and credulity to trust. CLINICAL IMPLICATIONS: Even though the magnitude and direction of effects remain to be clarified, patients with epistemic mistrust may enter a self-reinforcing cycle of reduced openness and ineffective mentalizing, potentially impacting therapeutic effectiveness. Interventions targeting epistemic disruption and impaired personality functioning seem to be crucial for improving therapeutic outcomes, including psychopharmacological treatment effectiveness.
