Objective:
The aim of this study was to determine whether Pregnant Women's Preferences for Mode of Delivery Questionnaire, created by Zamani-Alavijeh et al., is a valid and reliable measurement tool for Turkish pregnant women.
Methods:
This study has a methodological research design and was conducted with 139 pregnant women who were randomly selected from those aged 18-35 years, who applied to obstetric clinic,.who had no previous prenatal losses and no systemic diseases, and who had conceived naturally. The data for this study were collected with the Personal Information Form and the Pregnant Women's Preferences for Mode of Delivery Questionnaire. To test the reliability and validity of Pregnant Women's Preferences for Mode of Delivery Questionnaire, Cronbach's α, split-half method, item analysis, Kendall's coefficient of agreement (W), explanatory factor analysis, and confirmatory factor were used.
Results:
The study found that Cronbach's α was 0.94, the Spearman-Brown reliability coefficient was 0.883, and the Guttman split-half was 0.880. Explanatory factor analysis revealed an 18-item structure with three factors having an eigenvalue exceeding 1, explaining 67.593% of the total variability, and factor loading between 0.40 and 0.64.
Conclusion:
Based on the scientific recommendations, the Turkish version of the Pregnant Women's Preferences for Mode of Delivery Questionnaire has adequate psychometric properties.
Frequently Asked Questions
Based on this study's findings, the questionnaire identifies specific maternal preferences by evaluating 18 items across three factors. This structured approach allows clinicians to quantify subjective attitudes toward vaginal or cesarean delivery, explaining 67.593% of the variance in participant responses within the Turkish obstetric population.
The researchers reported a Cronbach's α of 0.94, indicating high internal consistency for the instrument. Additionally, the Spearman-Brown reliability coefficient reached 0.883 and the Guttman split-half value was 0.880, confirming the stability of the scale for measuring preferences in women aged 18 to 35.
The study used explanatory factor analysis to determine the underlying dimensions of the 18-item scale. This method revealed three factors with eigenvalues exceeding 1, which ensured that the Turkish adaptation maintained a statistically sound structure with item factor loadings ranging between 0.40 and 0.64.
The results are confined to Turkish pregnant women aged 18-35 who conceived naturally and had no history of prenatal losses or systemic diseases. The authors suggest that the psychometric properties may differ in populations with high-risk pregnancies or those who used assisted reproductive technologies.
The study's authors propose that the Turkish version of the questionnaire should be integrated into routine prenatal care to facilitate personalized counseling. They state that using this reliable tool helps healthcare providers address maternal fears and improve the decision-making process for mode of delivery.
