The effect of educational intervention based on self-efficacy theory on pregnancy anxiety and childbirth outcomes among Iranian primiparous women

Pregnancy anxiety is associated with a diverse birth outcomes. Mothers' education could have a critical role in increasing their self-efficacy to defeat their anxiety and improve pregnancy and child birth outcomes. The study was conducted to examine the effect of intervention based on self-efficacy theory on pregnancy anxiety and child birth outcomes.

The study was conducted as a quasi-experimental design on 60primiparous women (26–28 weeks) in Birjand (East Iranian province) from May to September 2017, who were randomly divided into intervention and control groups. The intervention group received 8 sessions of 90-min educational intervention based on self-efficacy theory strategies besides the routine prenatal care. Vanden Bergh's pregnancy anxiety questionnaire and checklist of pregnancy and delivery outcomes were used for data collection.

The level of pregnancy anxiety was similar in both groups before the intervention, but immediately and 1 month after the intervention, the mean score of pregnancy anxiety significantly reduced in the intervention group and significantly increased in the control group (P < 0.001). There was a significant difference in mean neonatal weight (P < 0.001) between the two groups. Emergency and elective cesarean section were significantly lower in the intervention group compared to the control group (P < 0.001), but there were no significant differences in the frequency of preterm delivery between two groups (P < 0.05).

The results provide support for the effectiveness of intervention based on self-efficacy theory in reducing pregnancy anxiety and enhancing positive pregnancy outcomes. Hence, theory-based educational interventions may serve as a cost-effective and noninvasive approach to reduce pregnancy anxiety in Iran.
