The adaptation of the Well-Being in Pregnancy (WiP) Questionnaire into Turkish: validity and reliability of a questionnaire.

This study aimed to adapt the Well-Being in Pregnancy (WiP) Questionnaire into Turkish and assess the instrument's validity and reliability in pregnant women. Exploratory factor analysis (EFA) was applied to 500 pregnant women included in Sample I, while confirmatory factor analysis (CFA) was applied to 386 pregnant women in Sample II. As a result of the EFA applied to Sample I, it was found that the 12-item WiP encompasses two factors (Positive Affect and Satisfaction subscale and Concerns subscale), and as a result of the CFA applied to Sample II, it was found that the scale has good fit indices (/df = 1.990,  = .000, CFI = 0.95, GFI = 0.95, AGFI = 0.93, RMSEA = 0.04, and PCLOSE = 0.000). The Cronbach's alpha internal consistency coefficients that were obtained as a result of the reliability analyses of the scale were found as 0.72, 0.70 and 0.60 for all items of WiP, its first subscale and its second subscale, respectively. It was found that the item-total correlations of the scale varied in the range of  = 0.44-0.55 ( < .001). In the test-retest analysis, a statistically significant positive correlation was found between the total scores of the scale obtained in two different implementations ( = 0.412,  = .024). This study supported the use of WiP as a valid and reliable instrument for Turkish pregnant women. Impact Statement The Well-Being in Pregnancy (WiP) Questionnaire developed in 2017 by Alderdice et al. is a measurement tool that is used to determine the positive and negative emotions of pregnant women. This questionnaire has not been translated to other languages. The reliability and validity of the Turkish version of WiP were found to acceptable, and two subscales were identified as the Positive Affect and Satisfaction subscale and the Concerns subscale. This reliable and valid instrument can be used for measuring the whole spectrum of well-being rather than just poor psychological health.
