The last couple of decades have seen a significant increase in the fields of research and clinical practice inspired by the theory of mentalising. Mentalisation, the capacity to understand one's own and others' behaviour in terms of mental states, is considered to be a "defining human social and psychological achievement" (Fonagy & Allison, 2014). The dialogue between mentalising theory and other fields such as developmental psychopathology or the neurosciences has added complexity and nuance to the understanding of this mental capacity. However, there is a gap in the research literature concerning the assessment of mentalising during therapeutic sessions. This assessment has often been done at the beginning and end of the treatment, missing session-to-session variations and the possibility to inquire about a mentalising style and its outcome in psychotherapy. This thesis describes the development and preliminary validation of the Mentalising Profile Q-set (MQS), an observer-rated measure that aims to bridge the gap between scientific research and clinical observations by describing the mentalising process of patients undergoing psychotherapy in a jargon-free language. The MQS focuses on the patient and provides a picture of the mentalising process in relation to its four polarities and pre-mentalising modes of experience. The data used in this research was derived from the Randomised Evaluation Study of Dynamic Interpersonal Therapy (REDIT) and the Tavistock Adult Depression Study (TADS), two trials that worked with depressed patients, although with differences in clinical characteristics. The preliminary results suggest that the MQS is an instrument that can differentiate groups of individual mentalising profiles and their likely effect on therapeutic outcomes, as assessed by the HRSD-17, at the beginning of treatment. The MQS contributes to the extant literature on assessment instruments and, at the same time, expands on the role of the capacity to mentalise in the therapeutic outcome.
