Attachment insecurity predicts responses to an interdisciplinary chronic pain rehabilitation program.

The aim of this study was to examine the hypothesis that attachment insecurity is associated with poorer responses to interdisciplinary treatment for chronic pain. Patients (n = 235) admitted to a 4-week interdisciplinary rehabilitation program were recruited. At pre-treatment, participants completed a battery of questionnaires assessing adult attachment styles and dimensions, as well as pain intensity, disability, self-efficacy, pain catastrophizing, and depressive symptoms. The latter measures were completed again at post-treatment. Nearly two-thirds of participants (65.5 %) reported having an insecure attachment style. Attachment insecurity was unrelated to pre- and post-treatment reports of pain intensity and pain-related disability, but was significantly associated with most other clinical variables at both time points. Regression analyses controlling for pre-treatment functioning indicated that attachment insecurity was associated with less improvement in pain catastrophizing, pain self-efficacy, and depressive symptoms. Further research is warranted to investigate the processes by which attachment characteristics influence patients' responses to chronic pain rehabilitation.
