PMID 31041323WHAT IT FOUND
A 31-item questionnaire for Iranian women’s labor pain captured five areas: transcendence, pain behaviors, readiness, internal distress, and external distress.
It related to the McGill and numerical pain scales, and repeated answers were stable, but testing was limited to Shiraz.
Key findings
01The final PLPQ had 31 items and five factors: transcendence with labor pain, nature of labor pain, preparation for labor pain, internal distress factors, and external distress factors.
02PLPQ scores were significantly correlated with Numerical Pain Rating Scale scores and short-form McGill scores (P<0.001).
03The scale’s internal consistency estimate was 0.80, and its test-retest stability estimate was 0.94.

What it does not show
The psychometric testing was done only among women in Shiraz, so it may not apply to other Iranian women or other settings. No confirmatory factor analysis was performed, so the five-factor structure needs further testing. Women who could not speak Persian, had mental disorders, had cesarean birth, had high-risk pregnancy, had infertility history, or used illicit drugs were excluded. The scale is culturally context-bound, especially the transcendence domain, so its meaning may not transfer to other populations.
The easy way to misread this
Do not assume the questionnaire is a validated labor pain measure for all women or that using it will improve birth experience. It was tested only in Iranian women in Shiraz who had uncomplicated vaginal births, and the study did not measure clinical outcomes.
