ABSTRACT
BACKGROUND: The concept of potential-to-experience is a major component in psychodynamic theory and assumed to be an important component of psychotherapeutic technique. However, as this assumption has never been empirically tested, the relationship between such interventions and treatment outcome is unclear. The aim of this pilot study is to explore the relationship between patient-therapist congruence of potential-to-experience engaged statements and the outcome of psychodynamic treatments. METHODS: Transcripts of 90 sessions from good- and poor-outcome treatments (N = 18) were encoded using the MATRIX - a novel content analysis tool of psychodynamic psychotherapy. Based on fixed algorithms, this observer-coding system is designed to identify different types of clinical interventions, including those which focus on the potential-to-experience. Total number of MATRIX codes analysed was 11,125. We compared the total congruence/incongruence ratio of such statements in good and poor treatments. The importance of the congruence/incongruence ratio of the potential-to-experience statements was measured by applying general linear models to classify treatment outcome. RESULTS: The congruence/incongruence ratio of the potential-to-experience engaged statements was significantly higher in good treatments. In the best model for classifying treatment outcome based on the congruence/incongruence ratios of several parameters, the congruence/incongruence ratio of the potential-to-experience engaged statements was the single most important predictor. DISCUSSION: Maintaining the congruence of potential-to-experience engaged statements within the therapeutic session is associated with better clinical outcome. This provides an initial empirical indication to the importance of the potential-to-experience discourse in psychotherapy praxis. PRACTITIONER POINTS: The concept of potential-to-experience is a major component in psychodynamic theory and assumed to be an important component of psychotherapeutic technique. The current results suggest that the ability of both patient and therapist to maintain the congruence of potential-to-experience statements within the session may improve clinical outcomes. These findings suggest a practical approach for a better management of the therapeutic process. Mainly, it recommends therapists to implement a very careful, active listening to potential-to-experience-related content throughout the session, while highlighting the patient's associations for their potential to become new modus operandi. Moreover, the current study presents an integrative, micro-level tool that enables the translation of complex theoretical concepts in psychotherapy into measurable constructs, aiming at the creation of a bridge between clinical theory and evidence-based practice.
