The factor structure of the childbirth self-efficacy inventory in a sample of Turkish pregnant women

Abstract

ABSTRACT
 Aim: Childbirth self-efficacy is very important for the type and management of birth. Women with high self-efficacy prefer vaginal delivery, manage labor pain more easily, need fewer analgesic interventions, and experience fewer complications at birth. This study aimed to examine the factor structure of the Childbirth Self-Efficacy Inventory Short-Version (CBSEI-32) in Turkish pregnant women.
 Material and Method: This study was conducted in a methodological design. The sample of the study consisted of the pregnant women admitted to the obstetrics and gynecology outpatient clinic of Karaman State Hospital. The data were collected using the descriptive information form for the pregnant and the CBSEI. Numbers, percentages, arithmetic mean, factor analysis, and Cronbach’s alpha coefficient were used in the data analyses. 
 Results: As a result of the exploratory factor analysis (EFA), items 6, 12, 13 and 16 in the OE sub-dimension were excluded because their factor load values were below 0.32. And the two-factor structure consisting of 28 items was obtained as the outcome expectancy (OE) and the self-efficacy expectancy (EE). Confirmatory factor analysis (CFA) was performed to obtain additional evidence of construct validity in line with the scores of the scale. It was determined that the fit indices calculated as a result of CFA without any modification were p=0.00, 2/SD; 2.43, GFI=0.90, AGFI=0.90, CFI=0.90, and RMSEA=0.06. The total Cronbach’s alpha reliability coefficient was 0.82. 
 Conclusion: The study demonstrated that the Turkish version of the “Childbirth Self-Efficacy Inventory” is a valid and reliable tool to measure the childbirth self-efficacy of women during pregnancy.
