Abstract:
Severe antenatal fear of childbirth causes adverse effects on emotional well-being during the postpartum period. The Wijma Delivery Expectancy/Experience Questionnaire is widely used to measure fear of childbirth among women before (version A) and after (version B) delivery. In this study, the original Swedish version was translated into Japanese, and its validity and reliability were examined among healthy, pregnant Japanese women. The Japanese-translated version presented a multidimensional structure with four factors: fear, lack of positive anticipation, isolation, and riskiness. Exhibiting concurrent/convergent validity, the Japanese version correlated with other psychological measures at expected levels. The Cronbach's α (0.90) and the intraclass correlation coefficient (0.86, P < 0.001) were high. In conclusion, the results provide support for the Japanese version to be considered a valid and reliable measure of prenatal fear of childbirth among pregnant Japanese women.

Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
