Abstract
Background & Aim: The high prevalence of cesarean section in most developed countries, exceeding 50%, has led to detrimental effects on maternal and child health. Vaginal birth after cesarean (VBAC) is a beneficial way to reduce cesarean rates. This study aimed to determine the effect of theory of planned behavior-based training on the intention and behavior of VBAC in pregnant women with previous cesarean section.
Methods & Materials: In this randomized controlled trial study, a convenience sample of 70 pregnant women with a history of cesarean section, referred to comprehensive health centers in Ardabil in 2020, were randomly assigned to either the intervention or control group. The intervention group received four weekly education sessions based on the theory of planned behavior structures, while the control group received standard care. Data were collected using a researcher-developed questionnaire at three time points: before, immediately after, and four weeks after the intervention. Data analysis was conducted using SPSS software version 16, employing independent t-test, Fisher’s exact test, chi-square test, and repeated measures ANOVA at a 95% confidence level.
Results: Repeated measures ANOVA revealed significant differences in mean scores of attitude, subjective norm, perceived behavior control, intention, and awareness over time between the intervention and control groups (P<0.001). However, the educational intervention did not lead to a behavior change.
Conclusion: Based on the findings, it is imperative for health planners to focus on providing organizational support and fostering a positive attitude among obstetricians and midwives to prioritize the implementation of VBAC.
