French version of the well-being in pregnancy (WIP) scale: translation and psychometric validation

BACKGROUND: This study aimed to validate the French version of the Well-being in Pregnancy (WiP) scale, a 12-item instrument assessing three dimensions of well-being during pregnancy: positive pregnancy, concerns over support after birth, and confidence in motherhood. METHOD: A sample of 299 pregnant women (second and third trimesters) in the French-speaking part of Switzerland completed an online survey. RESULTS: Confirmatory factor analysis supported the original three-factor structure of the WiP and showed good internal consistency. Differences in the WiP scores were found according to women's employment status, financial resources, pregnancy trimester, pregnancy complications, parity, and previous childbirth complications. However, given the nature of the data, measurement invariance could not be examined and group comparisons should be interpreted with caution. The WiP scores were positively correlated with life satisfaction, positive affect, and negatively correlated with negative affect, anxiety and depression symptoms. CONCLUSION: The French WiP is a valid tool for assessing well-being during pregnancy and represents a valuable resource for both research and antenatal care.
