Therapist initial attachment style, changes in attachment style during training, and client outcome in psychodynamic psychotherapy.

This study extended the cross-sectional therapist attachment literature by examining longitudinal changes of therapist attachment avoidance and anxiety in relation to client treatment outcome. Data consisted of 942 Outcome Questionnaire-45 assessments (Lambert et al., 1996, 2004) of 213 clients working with 30 therapists from a university clinic that provided psychodynamically/interpersonally oriented individual therapy, and yearly therapist self-report of attachment styles using the Experience in Close Relationships Scale (Brennan et al., 1998) over 2-4 years of training at a university clinic. Using multilevel growth modeling, we found that initial attachment anxiety or avoidance alone were not associated with treatment outcomes. Instead, therapists with small increases in attachment avoidance, from a low avoidance baseline, were more effective in helping clients reduce psychological distress than their peers. Findings suggest that small increases in attachment avoidance may be a beneficial development for trainees, as it may reflect a process of learning emotional boundary regulation (Skovholt & Rønnestad, 2003) and taking on the observer aspect of the participant-observer role (Sullivan, 1953). Current findings challenged the assumption that higher therapist attachment avoidance and anxiety is always associated with worse client outcome and suggested the importance of continuous self-reflection to understand how one's own attachment change impacts their clinical practice.
