The active ingredients of dynamic interpersonal therapy (DIT): an exploration of clients’ experiences

Abstract

The current article focuses on client’s perspectives of the mechanisms of change in Dynamic Interpersonal Therapy (DIT), a brief psychodynamic therapy developed for the treatment of depression. Five participants were interviewed and the transcripts were analysed using Interpretative Phenomenological Analysis (IPA). The results point out four subthemes, capturing different active ingredients of DIT: therapy shedding light on previously sealed aspects of self; the relational exchange with the therapist challenging intimate fears; moving towards an interpersonal understanding of their difficulties; and putting the pieces of their lives together into a coherent narrative. Overall participants described an interplay between relational and insight-oriented mechanisms taking place. As part of the former mechanisms, participants reported the development of a secure attachment to their therapist and the provision of a new relational experience, partly via mechanisms corresponding to the concept of transference. Participants reported an increase in insight to have been achieved via an understanding of an interpersonal and emotional pattern as well as via the restoration of a coherent life-story. Processes that theoretically map onto the concept of mentalisation were also reported. The findings are discussed in relation to the DIT and psychodynamic theory about change and to relevant research literature.
