The Patient Attachment Coding System is a valid measure of attachment that can classify clients' attachment based on any single psychotherapy transcript, in many therapeutic modalities Client differences in attachment manifest in part independently of the therapist's contributions Client adult attachment patterns are likely to affect psychotherapeutic processes.

There is currently little empirical evidence regarding how patients' attachment patterns manifest in individual psychotherapy. This study compared the in-session discourse of patients classified secure, dismissing, and preoccupied on the Adult Attachment Interview (AAI). Rather than focusing on content or form alone, this study analyzed how patients' discourse elicits and maintains emotional proximity with the therapist. The AAI was administered to 56 patients prior to treatment and one session for each patient was rated with the Patient Attachment Coding System (PACS) by four independent raters, blind to patients' AAI classification. Significant differences were found in the discourse of patients with different attachment patterns. Namely, secure and preoccupied patients showed more contact-seeking behavior than dismissing patients, who avoided emotional proximity more, while preoccupied patients resisted therapists' help more than did secure and dismissing patients. These results suggest that the different attachment patterns may have distinctive manifestations in the psychotherapy process that can be tracked by external observers.

These results suggest that the PACS Exploring scale might be a practical method for assessing RF in psychotherapy research and a way for researchers and clinicians to track patients' RF on an ongoing basis. These results also provide information regarding the ways in which differences in RF manifest during psychotherapy sessions. Clinical or methodological significance of this article Researchers and clinicians can assess patients' mentalizing based on any single psychotherapy transcript, in many therapeutic modalities The Exploring scale of the Patient Attachment Coding System can yield a reliable measure of reflective functioning based on any single psychotherapy transcript, in many therapeutic modalities Client differences in mentalizing manifest in part independently of the therapist's contributions.

In the last decade of his career, Jeremy Safran became increasingly interested in investigating the ways in which attachment representations influence the therapeutic relationship. In this paper, we test such influence in a sample of thirty outpatients who received Brief Relational Therapy by comparing their independently coded pre-treatment Adult Attachment Interview (AAI) with their narratives in a post-treatment interview about the relationship with the therapist (the Patient Relationship Interview at Termination, PRI-T). The PRI-T was coded with the following three measures: i) The Patient Attachment to Therapist Rating Scale (PAT-RS), which assesses the quality of the patient’s attachment relationship to the therapist; ii) the Coherence scale from the AAI, adapted for use on the PRI-T; and iii) the Patient Attachment Classification System (PACS), which measures generalized differences in how individuals convey their experiences and feelings. Results suggest that patients’ AAI predicts how they experience, represent, and communicate about the therapeutic relationship at the end of treatment, as shown by the PAT-RS, the Coherence scale adapted for use on the PRI-T, and the PACS applied to the PRI-T. These findings lend support to Safran and others’ hypothesis that patients’ AAI-status plays a role in patients’ representations of the relationship with the therapist.

In this article, we examine how the different attachment patterns enable or hinder the resolution of ruptures in the therapeutic alliance. We try to show that secure and insecure patients alike may experience ruptures in the therapeutic alliance, but that their ability to participate in such ruptures differ markedly. Recent findings with the Patient Attachment Coding System (PACS) show that attachment classifications manifest in psychotherapy as distinct ways of communicating about present internal experience. Secure patients disclose their present experience openly and invite attunement from the therapist, while insecure patients either minimize their contributions to the dialogue (avoidant) or the contributions of the therapist (preoccupied). Using examples from session transcripts, we demonstrate how secure patients are particularly responsive to resolution strategies that focus on here-and-now experience, while insecure patients' characteristic ways of communicating pose significant challenges to the resolution process.
