Mental flexibility and epistemic trust through implicit social learning – A meta-model of change processes in psychotherapy with personality disorders

This position paper follows the call for transtheoretical meta-models of general clinical change by concentrating on severe mental illness such as Personality Disorders (PDs). We have identified a core process of change related to mental flexibility through implicit learning and propose recommendations for stance and technique that are informed by research on Mentalization-Based-Treatment (MBT) and the learning components as represented in the Mediational Intervention for Sensitizing Caregivers (MISC). While the idea of corrective emotional experience as a general change mechanism involves discriminating between an old and new relationship to update relationship knowledge, the capacity to understand and process corrective emotional experiences may be limited and even iatrogenic in patients with PDs. By integrating MBT and MISC, a meta-model of change is created that allows training in and observation of the granular-level, behaviorally anchored, actions taken by the therapist to open up social learning. Here, social learning is conceptualized as epistemic trust, increasing the client’s reflective functioning during sessions to ultimately enhance cognitive flexibility outside the therapy room. This opens the possibility to implement and observe micro changes in what should be termed now implicit cognitive and emotional corrective experiences. Thus, we propose to shift towards implicit learning within professional relationships; that is, internalizing a new way of thinking about any life-event that requires adaption thereby creating adaptive capacities via mental flexibility as the general change mechanism of Personality Disorder (PD) treatment. peerReviewed publishedVersion
