The interpersonal paradigm of personality assessment provides a rich nomological net for describing and assessing constructs of interpersonal functioning. The aim of this article is to demonstrate for clinicians how the use of a multisurface interpersonal assessment (MSIA) battery can augment psychotherapy (e.g., cognitive-behavioral therapy). We present 2 clinical case examples and specify interpretative guidelines for MSIA that integrate multiple circumplex profiles (e.g., problems, traits, sensitivities, strengths, values, and efficacies) for each patient. Subsequently, we demonstrate how this approach provides a context to better understand patient symptoms and difficulties, and discuss how it can inform case conceptualization, treatment planning, and intervention.
