Aim
To identify differences between defense styles and mechanisms in sciatica patients with or without neuropathic pain and their relationship to quality of life.
Study design
The study included 37 sciatica patients with neuropathic pain (SNP), 36 sciatica patients without neuropathic pain and 38 healthy subjects. Pain severity was measured using the Visual Analogue Scale (VAS). Psychological condition was assessed using the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI). Defense mechanisms were assessed using a 40-item Defense Style Questionnaire (DSQ-40) and quality of life was assessed using Short Form-36 (SF-36).
Results
BDI and BAI scores were significantly higher in the SNP group (p < 0.001). Idealization and immature defense styles, as well as isolation, displacement and somatization were significantly higher in the SNP group (p < 0.05). SF-36 parameters also differed significantly between the groups, with controls having the best scores and the SNP group the worst. In linear regression analysis, acting out and BDI were found to affect the pain domain of the SF-36 (p < 0.001).
Conclusion
The acting out defensive style and BDI were independently associated with pain-related quality of life. In the SNP group, significant differences were found in the immature and neurotic styles of the defense mechanisms.
