Correlation Between Brief Ppain Inventory (BPI) and Pelvic Girdle Questionnaire (PGQ) In Evaluation of Pelvic Girdle in Pregnant Women

Pain in the lower back and pelvic pain are one of the most common problems in pregnancy. Appropriate and low-cost diagnostic and validated measurements are required. Therefore, there is a need for a reliable, valid and responsive measurement tool.

This descriptive study was performed on 135 pregnant women with pelvic pain referring to Shahid Beheshti University of Medical Sciences in Tehran in 2017. The data collection tool was a participant's personal information form, pelvic pain questionnaire, and brief pain inventory. The results were analyzed by descriptive, correlation and regression tests using SPSS 22. The P-value>0.05 was considered significant.

The mean and standard deviation of age in women were 29.43±5.7 years. The mean pain based on the pelvic belt tool was 37.00±18.00 and the mean pain was 4.25 ± 1.87, respectively. There was a significant positive correlation between the two tools in the sensory evaluation of pregnant women (r=0.818, P=0.001). The pelvic girdle questionnaire, according to R2 = [0.669, BPI=1.109+ 0.085(PGQ)], predicts the amount of pain in the pain relief tool.

Considering the importance of pelvic girdle and a significant correlation between these two questionnaires, it seems useful to use a questionnaire and a tool with a high degree of accuracy which requires shorter time to complete. Therefore, it can be concluded that a brief pain instrument is a useful tool for measuring pain and its effects in the life of patients with pelvic girdle.
