Accuracy of pain recall in chronic and recurrent low back pain

Physiological and psychological stressors, disease state, and psychosocial factors may influence recall accuracy in low back pain (LBP) reporting. The literature indicates that duration or frequency of the painful episode(s) may exert a greater influence on recall accuracy than pain intensity. The f ocus of this study is the recall accuracy in self-report of pain by a chron ic, nonspecific LBP population. This retrospective study examined recall ac curacy of LBP at 1-week, 1-month, and 6-month intervals as compared to self -report using daily pain diaries. Significant differences in recall accurac y were found at the 6-month recall period, but not at the 1-week or 1-month periods. Significant differences in accuracy were found between men and wo men at the 6-month recall period. Subjects with recurrent LBP were more acc urate than subjects with more chronic pain. Pain level or intensity was not shown to effect recall.
