Abstract

This study examines the relationship between secure attachment, therapeutic alliance, and psychotherapy satisfaction within the context of pluralistic psychotherapy. To capture clients’ subjective experiences beyond symptom reduction, this research introduced a brief psychotherapy satisfaction measure designed specifically for the study.

Using a quantitative, non-experimental cross-sectional design, data were collected from 206 participants who had completed a course of psychotherapy. Participants completed an attachment style inventory, a therapeutic alliance measure, and a bespoke satisfaction questionnaire. The study aimed to determine whether therapeutic alliance moderated and/or mediated the relationship between secure attachment and satisfaction.

Moderation analysis showed that therapeutic alliance significantly moderated this relationship: secure attachment predicted higher satisfaction at lower levels of alliance, suggesting that a strong alliance can offset less secure attachment. Mediation analysis indicated that therapeutic alliance fully mediated the link between secure attachment and satisfaction, highlighting the therapeutic relationship as the key mechanism through which attachment influences client experience.

These findings underscore the central role of alliance within pluralistic psychotherapy and that, while secure attachment supports engagement and satisfaction, a strong alliance can buffer the effects of insecure attachment. Implications include the potential value of considering attachment styles in clinical formulation and the importance of collaborative, flexible, and meta-therapeutic processes.

Limitations include reliance on self-report measures and the need for further validation of the satisfaction scale. Future research could examine therapist attachment styles and investigate pluralistic processes, such as client preference and shared decision-making, in greater depth.
