Abstract

OBJECTIVE: The combination of chronic musculoskeletal pain and depression is associated with worse clinical outcomes than either condition alone. In this study, we report the predictors of pain intensity and activity interference in primary care patients with co-morbid pain and depression. METHODS: This is a secondary data analysis of the 250 persons who participated in a randomized clinical trial designed to test the effectiveness of 12 weeks of optimized antidepressant therapy for both depression and pain. Using multivariate linear regression analysis, we assessed the predictive value of baseline self-efficacy, fear of movement, pain beliefs, and demographic and clinical factors on 3-month Graded Chronic Pain Scale pain intensity and activity interference outcomes. RESULTS: In the full model, significant sociodemographic predictors of less activity interference included being non-white (beta-5.8, P = 0.04) and being employed (beta-13.3, P < 0.0001). The latter was also predictive of less pain intensity (beta-5.6, P = 0.01). As expected, the optimized antidepressant treatment arm was associated with improved outcomes (pain intensity: beta-3.7, P = 0.0005 and activity interference: beta-6.4, P = 0.01). Whereas stronger perceived pain control (beta 3.6, P = 0.01) was associated with greater activity interference, higher degree of fear of movement (or fear avoidance) predicted greater pain intensity (beta 0.46, P = 0.04) and activity interference (beta 0.57, P = 0.05). Neither the location (low back vs hip/knee) nor duration of pain were predictive of pain intensity or interference outcomes. CONCLUSION: The findings are consistent with a bio-psychosocial model, implicating the need to consider the impact of sociodemographic variables and pain-related beliefs and cognition on pain-related outcomes for patients with co-morbid musculoskeletal pain and depression.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
