Validity and reliability of the Greek version of Wijma delivery expectancy/experience questionnaire (Version A) among low-risk pregnant women

Abstract

Abstract Background Fear of childbirth is a frequent health issue for pregnant women. The Wijma Delivery Expectancy/Experience Questionnaire (W-DEQ) is a widely used instrument to measure the fear of childbirth during the antenatal period. The aim of the study was to assess the psychometric properties of the W-DEQ (version A) in a sample of Greek pregnant women. Methods Low-risk pregnant women in the second or third trimester of pregnancy (N = 201) were invited to participate in the study and to complete a booklet of questionnaires including the Greek versions of W-DEQ-A, State-Trait Anxiety Inventory (STAI), Coping Orientations to Problems Experienced (Brief COPE), Perceived Stress Scale (PSS-10) and Edinburgh Postnatal Depression Scale (EPDS). Exploratory (EFA) and confirmatory factor analysis (CFA) was performed. Results The mean age of participants was 34.2 years (SD = 4.3 years). EFA yielded six factors (“Lack of self-efficacy”, “Lack of positive anticipation”, “Lack of feeling lonely”, “Concerns about delivery and losing control”, “Calmness”, and “Concern for the child”) of 33 items of W-DEQ-A. CFA confirmed the multidimensionality of the instrument. All Cronbach’s alpha were over 0.7, indicating acceptable reliability of the factors. All factors were significantly correlated with each other, and convergent validity was demonstrated by a significant association with stress, anxiety, and depression among low-risk pregnant women. Conclusion The Greek version of W-DEQ-A proved to be a valid and reliable instrument of fear of childbirth among Greek low-risk pregnant women.
