Individuals with persisting pain often present a constellation of symptoms that includes pain, health-related impairment and dysphoric mood. It is now widely accepted that comprehensive assessment must address each of these dimensions. Despite recognition of the value of multidimensional assessment, no empirical efforts have validated the construct of a multidimensional clinical outcome presentation based on the dimensions of pain, impairment and dysphoric mood. ⋯ MANOVA results indicated that the outcome groups were differentiated statistically across assessments. The multiple outcome measures did not change significantly across time, nor did the outcome groups change differentially across time on these measures. We conclude that the outcome dimensions of pain, impairment and depression are relatively stable phenomena that differentially describe CLBP patients.

Comparative Study
The pain drawing and Waddell's nonorganic physical signs in chronic low-back pain.
Pain drawings were obtained from a group of 651 patients who had chronic low-back pain. Pain drawings were rated in four grades according to the degree of organic and nonorganic pain. Experienced and inexperienced evaluators were used. ⋯ A correlation between pain drawings and Waddell's nonorganic physical signs demonstrated that a large proportion of patients with high Waddell scores had nonorganic pain drawings. No significant differences were noted in the distribution of Waddell scores and pain drawings based on patient gender or payment status (i.e., medicolegal or workers' compensation). Pain drawings afford an important adjunct in the physician's assessment of chronic low-back pain.

The purpose of this study was to identify Sickness Impact Profile (SIP) items that are most sensitive to change in patients with low-back pain. Seventy-six patients with low-back pain were administered the SIP at their initial visit and after discharge from physiotherapy treatment. A formal item reduction was performed to identify the most sensitive items. ⋯ Twenty items were identified. Seven of the 20 items identified in this study appear on the Roland-Morris disability questionnaire. Also, only 50% of the items identified are from the physical subscale of the SIP.

Comparative Study
A psychosocial and behavioral comparison of reflex sympathetic dystrophy, low back pain, and headache patients.
Based primarily on anecdotal evidence, patients with reflex sympathetic dystrophy (RSD) have often been suspected of having a high degree of psychosocial disturbance prior to the onset of symptoms as well as in reaction to the disorder. In the present study, patients presenting to a pain center with RSD were compared to patients with low back (LBP) and headache pain (HAP) on a variety of self-reported demographic, behavioral, pain, and mood measures. ⋯ This paradox may be due to the lesser chronicity of the RSD patients as well as to their apparently experiencing a more sympathetic response from doctors, employers, and insurance carriers than their LBP and HAP counterparts. On balance, the present data do not support the hypothesis the RSD patients, relative to other pain patients, are uniquely disturbed in psychosocial functioning.

To determine the intercorrelation between subjective disability, as assessed with the Pain Disability Index (PDI) and the Oswestry Disability Questionnaire (ODQ) and their correlation with visual analogue scale (VAS) pain intensity ratings. ⋯ The present results suggest that either the PDI or the percentage score PDI and also the even shorter-to-administer PDI factor 1 may be useful and reliable tests for the assessment of subjective disability in low back pain patients. As noted by the moderate intercorrelations with pain intensity scores, both the PDI and the ODQ address a broader concept of disability than that directly related to pain intensity.
