To determination the predictive power of the theory of planned behavior intended Natural Childbirth in pregnant women in Birjand
Abstract
Background and Aim: Given the increasing rate of cesarean sections in Iran as a major health problem and its effects on maternal mortality, this study aimed to assess the predictive power of the theory of planned behavior on the intended natural childbirth in pregnant women of Birjand city. Materials and Methods: In this cross-sectional study, 195 pregnant women at 20 to 24 gestation weeks in Birjand in 2015 were incorporated via convenience sampling method. Grab tool standardized questionnaire was consistent with the structure theory of planned behavior. The reliability using Cronbach's alpha as for questions of awareness and attitude, perceived behavioral control, and subjective norms were 0.71, 0.71, 0.87, and 0.87 respectively. The data were analyzed in SPSS [V. 16]. To determine the correlation between constructs, Pearson correlation coefficient was used. To determine the share of each of the constructs, regression analysis was used. The significance level was considered as P<0.05. Results: The average age of pregnant women participating in the study was 26.07±5.4 years. A significant positive correlation was observed between all variables of the model of planned behavior (P <0.05). The results indicate that the constructs of the theory of planned behavior can predict the intention with a 0.53 variance. Subjective norm constructs (P< 0.05 and β=0.415) and perceived behavioral control (P <0.05 and β=0.342) were respectively the best predictors of intent to childbirth. Conclusion: Theory of planned behavior can predict a woman's childbirth plan.
