AbstractCurrently, little is known about the influence of depressive symptoms and gender-specific aspects in rehabilitation outcome of patients with chronic low back pain. Effects of gender and depressive symptoms on rehabilitation outcome were examined immediately after rehabilitation, as well as three and six months after rehabilitation in 116 patients with chronic low back pain (43 women, 73 men; M=48 yrs.; ICD-10 diagnoses: M45.4/M45.5, M54.4/M54.5). Immediately after rehabilitation, general improvements with medium effect sizes in all rehabilitation measures were found. In contrast, six months after rehabilitation, only pain-related measures showed moderate improvements. Additionally, the mid-term outcomes were influenced by gender and depressive symptoms; women showed more stable rehabilitation outcomes in pain intensity, in the impaired function related to family/leisure, and the coping with pain strategies of "perceived self-competence" and "relaxation". In contrast, especially male patients with severe depressive symptoms revealed regressive rehabilitation outcomes, both in pain-related variables as well as marginally in the coping with pain strategy of "cognitive restructuring". In post-hoc analyses, in the mid-term, they even showed a deterioration of functional capacity and somatisation compared to prior to rehabilitation. Our results suggest that the outcome of orthopaedic rehabilitation may be persistently improved by implementing gender-specific treatments in general and elements of depression treatments for the patients with severe but sub-clinical depressive symptoms.
