Are childhood adversities relevant in patients with chronic low back pain?

subject

description

Abstract Previous studies have found a high number of childhood adversities in patients with chronic low back pain, particularly in patients reporting persisting problems after back surgery. Our aim was to reproduce these results. Within the framework of a comprehensive diagnostic assessment and psychometric evaluation, 109 inpatients who had been treated for low back pain were examined in the orthopedics department of a German university hospital. Five risk factors investigated by Schofferman and his staff (Schofferman et al ., 1993) were re-assessed in all of our patients using a structured biographical interview. The German chronic low back pain group was also compared with an age- and gender-matched control group of 109 non-chronic pain patients with respect to these childhood adversities and additional ones. Only approximately 11% of the German chronic low back pain sample demonstrated three or more risk factors, compared with more than 50% in Schofferman's sample, and 47.7% showed none of the five risk factors, compared to only 11% in the Schofferman sample. Moreover, no significant differences in distribution either in terms of the individual risk factors or their cumulative frequency were found in the German chronic low back pain group compared with an age and gender-matched control group without chronic pain. Childhood adversities do not occur frequently in a non-selected group of patients with chronic low back pain. Earlier results showing an increased likelihood of the occurrence of psychosocial risk factors could not be confirmed. As a consequence, further psychic or psychosomatic diagnostics of patients with chronic low back pain are needed to define diagnostic subgroups.
