"They also present two cases that illustrate how the quality of mentalization or reflective function in the therapeutic dyad may be seen as a bidirectional process in that therapists' and patients' levels of reflective function are mutually and reciprocally influential.
In one case, the patient's and therapist's reflective function mirrored each other directly and remained at a low or rudimentary level for the treatment year. Such a pattern of direct imitation does not necessarily promote intrapsychic change.
In the second case, the patient moved from a rejecting or bizarre stance toward mentalization on the AAI to some rudimentary consideration of mental states after 1 year of treatment with a therapist who showed a full and nuanced awareness of mental states, but who adjusted his level of mentalization to that of the patient. These findings suggest that optimally the therapist ought to be one step ahead of the patient in the capacity for mentalization."
