The quality of prenatal dental services is essential for improving the oral health of both mothers and children. However, a lack of a reliable tool to assess the quality of prenatal oral care has hindered research in this area. To address this gap, the study aimed to validate the Organizational Determinants of Prenatal Dental Services Questionnaire (OD_PDS) in Iranian pregnant women.
Literature reviews, interviews, and a cross-sectional survey with 300 pregnant women were conducted. To evaluate the validity; face, content and construct validity were assessed. Cronbach's alpha coefficient and the Test-retest method were used for reliability assessment.
The final version of the OD_PDS comprises 12 items, and four subscales, which are Costs (four items), Access to Equipment and services (three items), Review of the service delivery process (two items), and Professional Behavior (three items). Questions with a factor loading of less than 0.3 were excluded. The obtained fit indices were acceptable (X2/pdf = 3.383, RMSEA: 0.089, CFI = 0.869, and TLI = 0.820). The content reliability was demonstrated by Cronbach's α = 0.702 and 0.713 and the ICC = 0.724.
The current study indicates that the OD_PDS is a valid and reliable tool for Prenatal Dental Services assessment in health centers.
产前牙科服务质量对于改善母亲和儿童的口腔健康至关重要。然而，缺乏可靠的工具来评估产前口腔护理质量阻碍了该领域的研究。为了填补这一空白，本研究旨在验证伊朗孕妇产前牙科服务组织决定因素问卷（OD_PDS）的有效性。
进行了文献综述、访谈，并对300名孕妇进行了横断面调查。为评估有效性，对表面效度、内容效度和结构效度进行了评估。使用Cronbach's α系数和重测法进行信度评估。
OD_PDS的最终版本包括12个项目和四个子量表，分别是成本（四个项目）、设备和服务获取（三个项目）、服务提供过程审查（两个项目）和专业行为（三个项目）。因子载荷小于0.3的问题被排除。获得的拟合指数是可接受的（X2/pdf = 3.383，RMSEA：0.089，CFI = 0.869，TLI = 0.820）。内容信度通过Cronbach's α = 0.702和0.713以及ICC = 0.724得到证明。
当前研究表明，OD_PDS是卫生中心产前牙科服务评估的有效且可靠的工具。
