Assessment
-
This study examined personality pathology in a group of patients with chronic low back pain (CLBP) using both diagnostic interviews and dimensional self-report instruments. A group of CLBP patients (N = 125) was assessed before functional restoration treatment and compared with a matched normal comparison group (N = 75). ⋯ Reductions in personality pathology between pre- and posttreatment assessments were more pronounced for diagnostic interview than dimensional self-report assessments. These results are discussed in the context of personality assessment and CLBP.
