Assessment of Repeated Relational Patterns for Individual Cases Using the SASB-Based Intrex Questionnaire

Repeated interpersonal patterns are central to case conceptualization and treatment planning in interpersonal and attachment-based approaches to therapy. In this study, raters (133 college students, 165 inpatients) provided data on the Intrex questionnaire (Benjamin, 2000 Benjamin, L. S. 2000. Intrex user's manual, Salt Lake City: University of Utah.  [Google Scholar]) about self-treatment, relationship with a significant other, and remembered interactions with parents in childhood. Within-subject profiles were inspected for precise behavioral matches conforming to 3 “copy process” (CP) patterns: identification (behaving like an important other), recapitulation (behaving as if the other person is still present and in charge), and introjection (treating the self the way another did). We observed CP evidence in most individual ratings. Consistent with expectation, nonclinical raters tended to copy a securely attached pattern of affiliation, low hostility, and moderate degrees of enmeshment and differentiation. Only patients copied maladaptive behavior at greater than base rate expectation. We discuss implications and provide recommendations for use of Intrex in individual assessment of CP.
