“…Furthermore, the results contribute to the explanation why mentalization-based treatment [54] has proven to be an effective strategy in psychotherapy [e.g., 55,56]: If mentalization has the ability to mediate intrapsychic processes and is associated with mental health, strategies to foster reflective functioning should be capable of enhancing the effects of psychotherapy. Since the direct link between adult attachment and distress in interpersonal contact does not seem to be significant when mentalization is controlled and attachment may be a difficult variable to change in psychotherapy [57], it appears advisable to include such strategies in other therapy approaches as well. Regarding the development and advancement of specific treatment strategies, we, therefore, propose research on integrative approaches that do not favor one aspect of the human mind, but consider the complex interaction of different spheres.…”
