This study aimed to validate a German version of the Pregnancy-related Anxiety Scale (PrAS-G) which consists of eight dimensions. The results showed that PrAS-G has good reliability and model fit, and it demonstrated good convergent, divergent, and predictive validity. PrAS-G provides a more comprehensive assessment of pregnancy-related anxiety, allowing for targeted interventions to improve birth experiences and well-being of expectant mothers.
BackgroundPregnancy-related anxiety has received greater research attention recently given its association with adverse outcomes (e.g., negative birth experiences). The Pregnancy-related Anxiety Scale (PrAS) offers the possibility to assess pregnancy-related anxiety, but no German version is available. Therefore, the aim of this study was to validate a German version of the PrAS, a comprehensive measure with eight dimensions.MethodsPregnant women of any parity or gestation completed an online survey consisting of the PrAS, PRAQ-R2, and measures of anxiety, depression, and resilience. The PrAS was translated into German (PrAS-G) using the back-translation method. Data were subjected to confirmatory factor analysis and inferential statistics.ResultsComplete data were provided by 443 women. Participants were predominantly German nationals, partnered, and well-educated with a planned pregnancy. Approximately half were nulliparous. The eight-factor model was well fitting and consistent with the development of the original PrAS. Criterion-related validity was demonstrated by strong correlations with similar measures (PRAQ-R2, anxiety, and depression) and lower correlations with resilience scores. Predictive validity was shown by group comparisons for: planned versus unplanned pregnancy, trimester, and parity.ConclusionsThe PrAS-G provides a broader assessment of pregnancy-related anxiety than existing measures. Initial evaluation has demonstrated convergent, divergent, and predictive validity, excellent internal consistency, and good model fit indicating promising psychometric properties. The PrAS-G offers a comprehensive assessment of pregnancy-related anxiety which will enable tailored interventions aiming to improve birth experience and well-being of expectant mothers.
