Previous work has suggested that chronic pain patients report psychological distress through higher endorsement of somatic rather than cognitive signs of anxiety and depression. The present study compared female Non-Pain (11=52), Orofacial Pain (n=3 17) and Fibromyalgia (n=50) groups. on SCL-90-R Somatization, Anxiety and Depression raw scores and cognitive-somatic symptom patterning of the Anxiety and Depression scales. Comparisons were also made amongst orofacial pain diagnostic subgroups and subgroups based on Multidimensional Pain Inventory (MPI) classification groups. The Somatization. Anxiety and Depression scores were higher in the OroFacial Pain and Fibromyalgia than Non-Pain group and higher in the Dysfunctional than Adaptive Coper MPI Profile group. No differences in somatic-cognitive symptom patterning existed among the diagnostic or the MPI groups/subgroups. OroFacial pain patients endorsing cognitive items stronger than somatic items on the Anxiety and/or Depression scales showed a tendency towards more psychopathology (higher SCL-90-R scale scores) than the participants endorsing somatic items more so than cognitive items. I n conclusion, study results indicate that differentiation of cognitive-somatic patterns does not contribute to increased understanding of chronic pain conditions.
