(HealthDay News) — For patients recovering from musculoskeletal trauma, psychological factors, especially catastrophic thinking, are associated with pain intensity and disability, according to a study published in the February 5 issue of The Journal of Bone & Joint Surgery.

Ana-Maria Vranceanu, PhD, from Massachusetts General Hospital in Boston, and colleagues estimated the prevalence of clinical depression and posttraumatic stress disorder (PTSD) at one to two months (Time 1; 152 patients) and five to eight months (Time 2; 136 patients) after musculoskeletal trauma.

The researchers found that the screening criteria for an estimated diagnosis of clinical depression were met by 35 and 29 patients at Times 1 and 2, respectively; and those for PTSD were met by 43 and 25 patients, respectively. At Time 1, 24 and 29% of the variance in pain and disability was explained by models that included multiple injuries, Abbreviated Injury Scale score, and self-reported opioid use. Incorporation of psychological variables into the models accounted for between 49% and 55% of the variance. The sole significant predictor of pain at rest, pain during activity, and disability at Time 2 was catastrophic thinking at Time 1.

“We found that psychological factors that are responsive to cognitive behavioral therapy — catastrophic thinking, in particular — are strongly associated with pain intensity and disability in patients recovering from musculoskeletal trauma,” the authors write.
