Childbirth self-efficacy is an individual’s confidence in her own expected ability to handle or perform behaviors when faced with the upcoming labor and birth appropriately. This support the primigravidas women to perform activities to achieve the desired goal. The purpose of this descriptive correlation research aimed to describe childbirth self-efficacy and to examine the relationship between social support, fear of childbirth, and childbirth self-efficacy among primigravidas. The participants were 85 primigravidas women aged 20-35 years, had the gestational ages between 28 and 41 weeks, and received antenatal care at the antenatal clinic at Khon Kaen Hospital between November 2017 to March 2018. The research instruments consisted of demographic questionnaire, the Thai Childbirth Self-Efficacy Inventory, Social Support Questionnaire and The Wijma Delivery Expectancy/Experience Questionnaire. Data were analyzed using descriptive statistics and Pearson's product moment correlation.
Results: The primigravidas had overall childbirth self-efficacy at a high level (= 214.96, S.D. = 34.41). Childbirth self-efficacy in the aspect of outcome expectations ( = 108.58, S.D. = 16.78) and the of self-efficacy expectations (= 106.38, S.D. = 19.56) were reported at a high level. Social support had a statistically significant moderate positive relationship with childbirth self-efficacy (r = .49, p <.01). Fear of childbirth had a statistically significant moderate negative relationship with childbirth self-efficacy (r = -.46, p <.01).
Recommendations: This research suggests that primigravidas should be assessed for social support, fear of childbirth, and childbirth self-efficacy. Nurse-midwives should develop strategies to promote social support and to decrease fear of childbirth in order to enhance childbirth self-efficacy among primigravidas.
