To show clinical utility and empirical validity of Minnesota Multiphasic Personality Inventory-2 (MMPI-2) chronic pain patient subgroups by identification of differential multivariate relationships across groups. ⋯ Consistent with previous cluster analytic studies, this study replicated four MMPI-2 cluster profile groups in chronic pain patients. These results have also shown that several multivariate relationships between variables are different across MMPI-2 groups, providing evidence for the validity for these MMPI-2 subgroups.

The purposes of this study were to explore the differences between chronic cancer pain and chronic low back pain with respect to (a) the use of coping strategies to manage pain and (b) the relationship between self-efficacy for attenuating pain and pain outcomes. ⋯ The major findings of this study were that (a) patients with chronic cancer pain reported significantly lower pain intensity and pain interference than did patients with chronic low back pain; (b) the most frequently used coping strategies were almost the same between the low back pain group and the cancer pain group; (c) for both chronic cancer pain and chronic low back pain groups, patients' perceived self-efficacy was significantly inversely correlated with pain intensity and pain interference with daily life; and (d) patients' use of coping strategies was positively correlated with pain intensity and pain interference with daily life. These findings were discussed in terms of implications for clinical practice and future research.

Randomized Controlled Trial Multicenter Study Clinical Trial
A randomized trial of a lay person-led self-management group intervention for back pain patients in primary care.
Randomized, controlled trial. ⋯ Self-management groups led by trained lay persons following a structured protocol were more effective than usual care in reducing worries, producing positive attitudes toward self-care, and reducing activity limitations among patients with back pain in primary care.

Randomized Controlled Trial Comparative Study Clinical Trial
Opioid therapy for chronic noncancer back pain. A randomized prospective study.
A randomized, open, long-term, repeated-dose comparison of an anti-inflammatory drug and two opioid regimens in 36 patients with back pain. ⋯ The results suggest that opioid therapy has a positive effect on pain and mood but little effect on activity and sleep. Opioid therapy for chronic back pain was used without significant risk of abuse. However, tapered-off opioid treatment is palliative and without long-term benefit.
