Abstract
The belief that rigidity across relationships is related to greater symptoms and poorer functioning commonly informs the practice of many psychodynamic and interpersonal therapists. Using a profile correlation approach, the authors tested this hypothesis in a sample of 250 clients and 90 undergraduate control participants. Symptoms and functioning were assessed with the Inventory of Interpersonal Problems (IIP;

), Global Assessment of Functioning Scale (

), and Brief Symptom Inventory (
L. R. Derogatis, & N. Melisaratos, 1983
). A revised version of the empirically derived Central Relationship Questionnaire (CRQ;
J. P. Barber, C. Foltz, & R. M. Weinryb, 1998
) was used to measure interpersonal patterns. Revisions were made to the CRQ to increase the interpersonal dimensions it captured, reduce its length, and model a higher order factor structure. The psychometric properties of the revised CRQ were found to be adequate. Rigidity, as measured with the CRQ, was not related to rigidity measured with the IIP (amplitude) and did not differ significantly among individuals with different interpersonal problems or
