Pregnant women's perception of risk may influence their health behaviors during pregnancy; however, no validated instrument exists to measure those perceptions. The purpose of this study was to refine a new instrument, the Perception of Pregnancy Risk Questionnaire (PPRQ), and conduct psychometric assessment of the final 9-item version. Reliability and validity were assessed using a sample of 199 women in the third trimester of pregnancy. Exploratory factor analysis resulted in a two-factor solution. Evidence of construct validity was demonstrated using the known-groups technique and through convergent validity. Ratings of pregnancy risk correlated with state anxiety level, providing evidence of concurrent validity. The PPRQ had high internal consistency reliability and excellent test-retest reliability.
孕妇对风险的认知可能会影响她们孕期的健康行为；然而，目前尚无经过验证的工具来测量这些认知。本研究的目的是完善一种新工具——妊娠风险认知问卷（PPRQ），并对最终的9项版本进行心理测量评估。使用199名孕晚期女性样本评估信效度。探索性因素分析得出了一个双因素解决方案。通过已知群体技术和收敛效度证明了结构效度。妊娠风险评分与状态焦虑水平相关，提供了同时效度的证据。PPRQ具有较高的内部一致性信度和出色的重测信度。
