Fonagy, P; Allison, E; (2014) The role of mentalizing and epistemic trust in the therapeutic relationship. Psychotherapy 10.1037/a0036505. 1 (Fonagy & Bateman, 2008). In this paper we will argue for the role of mentalizing in the therapeutic relationship, suggesting that although Mentalization-Based Treatment (MBT) may be a specific and particular form of practice, the "mentalizing therapist" is a universal constituent of effective psychotherapeutic interventions. RESEARCH ARTICLE

Mentalizing is the capacity to understand others and oneself in terms of internal mental states. It is assumed to be underpinned by four dimensions: automatic–controlled, internally–externally focused, self–other, and cognitive–affective. Research suggests that mental disorders are associated with different imbalances in these dimensions. Addressing the quality of mentalizing as part of psychosocial treatments may benefit individuals with various mental disorders. We suggest that mentalizing is a helpful transtheoretical and transdiagnostic concept to explain vulnerability to psychopathology and its treatment. This review summarizes the mentalizing approach to psychopathology from a developmental socioecological evolutionary perspective. We then focus on the application of the mentalizing approach to personality disorders, and we review studies that have extended this approach to other types of psychopathology, including depression, anxiety, and eating disorders. We summarize core principles of mentalization-based treatments and preventive interventions and the evidence for their effectiveness. We conclude with recommendations for future research.

A new developmental model of borderline personality disorder (BPD) and its treatment is advanced based on evolutionary considerations concerning the role of attachment, mentalizing, and epistemic trust in the development of psychopathology. We propose that vulnerability to psychopathology in general is related to impairments in epistemic trust, leading to disruptions in the process of salutogenesis, the positive effects associated with the capacity to benefit from the social environment. BPD is perhaps the disorder par excellence that illustrates this view. We argue that this conceptualization makes sense of the presence of both marked rigidity and instability in BPD, and has far-reaching implications for intervention.

This paper sets out a recent transition in our thinking in relation to psychopathology associated with personality disorder, in an approach that integrates our thinking about attachment, mentalizing (understanding ourselves and others in terms of intentional mental states) and epistemic trust (openness to the reception of social communication that is personally relevant and of generalizable significance) with recent findings on the structure of both adult and child psychopathology and resilience. In this paper – the first of two parts – we review evidence suggesting that a general psychopathology or p factor underlies vulnerability for psychopathology. We link this p factor to a lack of resilience using Kalisch and colleagues’ positive appraisal style theory of resilience (PASTOR). We argue that vulnerability for (severe) psychopathology results from impairments in three central mechanisms underlying resilience – positive situation classification, retrospective reappraisal of threat, and inhibition of retraumatizing triggers – which in turn result from a lack of flexibility in terms of social communicative processes. We suggest that, from this perspective, personality disorders, and borderline personality disorder (BPD) in particular, can be considered to be the prototype of disorders characterized by a lack of resilience. Part 2 proposes an evolutionary developmental psychopathology account linking this inflexibility in social communication to problems with the development of epistemic trust – that is, an evolutionary pre-wired social communication system that normally facilitates resilience through salutogenesis, that is, the capacity to learn and derive benefit from the (social) environment.

In Part 1 of this paper, we discussed emerging evidence suggesting that a general psychopathology or ‘p’ factor underlying the various forms of psychopathology should be conceptualized in terms of the absence of resilience, that is, the absence of positive reappraisal mechanisms when faced with adversity. These impairments in the capacity for positive reappraisal seem to provide a comprehensive explanation for the association between the p factor and comorbidity, future caseness, and the ‘hard-to-reach’ character of many patients with severe personality pathology, most notably borderline personality disorder (BPD). In this, the second part of the paper, we trace the development of the absence of resilience to disruptions in the emergence of human social communication, based on recent evolutionary and developmental psychopathology accounts. We argue that BPD and related disorders may be reconceptualized as a form of social understanding in which epistemic hypervigilance, distrust or outright epistemic freezing is an adaptive consequence of the social learning environment. Negative appraisal mechanisms become overriding, particularly in situations of attachment stress. This constitutes a shift towards a more socially oriented perspective on personality psychopathology in which the absence of psychological resilience is seen as a learned response to the transmission of social knowledge. This shift in our views has also forced us to reconsider the role of attachment in BPD. The implications for prevention and intervention of this novel approach are discussed.

This paper seeks to elucidate the phenomenological experience of psychotherapy in the context of the theory of mentalizing and epistemic trust. We describe two related phenomenological experiences that are the domain of psychotherapeutic work. The first is the patient's direct experience of their own personal narrative being recognised, marked and reflected back to them by the therapist. Secondly, this intersubjective recognition makes possible the regulation and alignment of the patient's imaginative capacity in relation to our phenomenological experiences. In describing three aspects of the communication process that unfold in effective psychotherapeutic interventions-1) the epistemic match, 2) improving mentalizing, and 3) the re-emergence of social learning-the way in which any effective treatment is embedded in metacognitive processes about the self in relation to perceptual social reality is explained. In particular, attention is drawn to wider social determinants of psychopathology. We discuss the possible mechanism for the relationship between the social-economic environment and psychopathology, and the implications of this for psychotherapeutic treatment.

Epistemic trust (ET) refers to trust in communicated knowledge. This paper describes the development and validation of a new self-report questionnaire, the Epistemic Trust, Mistrust and Credulity Questionnaire (ETMCQ). We report on two studies (Study 1, n = 500; Study 2, n = 705) examining the psychometric properties of the ETMCQ and the relationship between EMTCQ scores (i.e., an individual’s epistemic stance) and exposure to adverse childhood experiences, mental health symptoms, attachment, mentalizing and general self-efficacy. The factor structure of the ETMCQ was examined using Exploratory and Confirmatory Factor Analyses, and its reliability and test-retest reliability were tested. Both studies yielded three correlated yet distinct factors–Trust, Mistrust and Credulity–and confirmed the reliability and validity of the ETMCQ. Preregistered hypotheses were confirmed and replicated across both studies. Main findings suggest intriguing links between the ETMCQ and developmental psychopathology constructs and are consistent with thinking on the role of epistemic stance in undermining adaptation and increasing the developmental risk of mental health problems. Mistrust and Credulity scores were associated with childhood adversity and higher scores on the global psychopathology severity index and both factors partially mediated the link between early adversity and mental health symptoms. Mistrust and Credulity were positively associated with difficulties in understanding mental states and insecure attachment styles. Post-hoc analysis identified that different attachment styles were associated with differences in epistemic stance. In addition, Trust was not associated with reduced levels of mental health symptoms and did not moderate the impact of childhood adversity–findings are congruent with the suggestion that the reduction of mistrust and credulity may be crucial common factors in promoting resilience and the effectiveness of psychotherapeutic interventions. This investigation and the ETMCQ provide an empirical measure of what until now has been largely a theoretical concept and open new avenues for future research.
