The Effect of an Educational Intervention Based on Protection Motivation Theory on Pregnant Women’s Knowledge and Self-Protection Regarding COVID-19. An Intervention Study

BACKGROUND: COVID-19 infection endangers pregnant women and newborns. Infection prevention measures are available and easy to apply, but the problem is the application continuity. Empowering pregnant women to increase their intention for self-protection is very important. This study explores the effect of educational intervention based on the Protection Motivation Theory (PMT) on pregnant women’s knowledge and self-protection regarding COVID-19. MATERIALS AND METHODS: A randomized, controlled trial was conducted at the Obstetrics and Gynecology outpatient clinic at El Shatby Hospital, Alexandria governorate/Egypt, from November 2020 to May 2021. The study included a convenient sample of 163 pregnant women using the randomization block technique. A self-reported questionnaire was used for data collection. For the intervention group, the PMT-based education included need assessment, planning, implementation, and evaluation. Two months later, a reevaluation was done. RESULTS: ANCOVA showed a significant improvement in the intervention group’s knowledge (F(1) = 8.56, p < 0.001) when taking the pretest as a reference. The effect size shows that 25.8% of the intervention group’s knowledge improvement and 58.80% of the difference between the two groups were due to intervention. ANCOVA showed a significant improvement in the intervention group’s PMT constructs when taking the pretest or group as a reference (p <0.001). The effect size shows that 56.10% of the intervention group’s total PMT constructs improvement and 89.60% of the differences between the two groups were due to the intervention. CONCLUSIONS: PMT-based intervention is effective in improving pregnant women’s knowledge and self-protection intention regarding COVID-19. PMT is recommended to tailor educational intervention for pregnant women.
