Pain or depression: which of them does have more influence on disability of chronic
pain?
27th Annual Meeting of the American Academy of Pain Medicine (AAPM) (Washington,
DC -- 3/24/2011)
Introduction: Multiple studies revealed extensive correlation between depression and
chronic pain. Statement of the Problem: The aims of this study was to determine the
presence of depression in patients with chronic rheumatologic pain and to find out that
which of severity of depression or severity pain has more influence on chronic pain
disability.
Materials and methods: Ninety-six patients with chronic rheumatologic pain were
assessed by McGill Pain Questionnaire (MPQ) for severity of pain, Hamilton Rating
Scale for severity of depression (HAM-D), and Multidimensional Pain Inventory (MPI).
Correlation coefficients and stepwise linear regression were used.
Results: Thirty one percent of the patients had clinical depression. The mean of HM-D
scores was 11.27±5.67. The MPI was significantly related to depression scores on the
HAM-D (r=0.537, p<0.001) and severity of pain scores on the SF-MPQ (r=0.29,
p=0.004). There was also a significant correlation between HAM-D scores and SF-MPQ
scores (r=0.407, p<0.001). Results of the stepwise regression analyses revealed that only
HAM-D scores was the added variable to the model (R=0.564, R2=0.318, F=43.923,
P<0.001, B=2.082, SE=0.314).
Conclusions: Findings showed that depression made more contribution in reducing
psychosocial dimensions of chronic rheumatologic pain.
