Objective: Pregnancy-related anxiety is a risk factor for poor outcomes. The aim of this study was to validate the Farsi version of the Anxiety Scale for Pregnancy (ASP) in a sample of Iranian women.
Materials andMethods: After translation and back-translation of the ASP, the content validity ratio (CVR) and the content validity index (CVI) of each item were calculated based on the opinions of a panel of 10experts. Four hundred pregnant women completed the Farsi version of the ASP,in the third trimester of pregnancy. For discriminant validity, we compared the ASP mean scores of women with low and high childbirthfears. Confirmatory factor analysis (CFA) was performed to investigate construct validity of the scale.
Results: No item hadCVR and CVI scores less than 0.62 and 0.8 respectively. The results of the CFA for the ASP were unsatisfactory for the proposed 5-factor model (RMSEA= 0.087, SRMR=0.092, Chi-square/df=4.03, CFI=0.87, GFI=0.91). After removing item 9, satisfactory CFA results was obtained and the structural model fit was confirmed (RMSEA= 0.066 (CI [0.053, 0.078]), SRMR=0.069, Chi-square/df=2.71, CFI=0.93, GFI=0.95). Cronbach’s alpha coefficient for the 13-item ASP was 0.703.The scale showed moderate correlations with the Spielberger State and Trait anxiety Inventory and Childbirth Attitudes Questionnaire (CAQ) scores (0.61, 0.59, and 0.57, respectively) and could differentiate well between women who preferred cesarean and those requesting vaginal delivery.
Conclusions:The present study confirmed the content validity and construct validity of the Farsi version of the 13-item ASP for women in the third trimester of pregnancy.
