To assess maternal confidence in her ability to cope with labor, a measure of childbirth self efficacy is necessary.
This paper aims to assess the cultural adaptation and psychometric testing of the short form of childbirth self-efficacy Inventory among Iranian pregnant women.
In this descriptive-methodological study, we investigated 383 Iranian pregnant women in the third trimester. They were recruited from the outpatient prenatal care clinic of Taleghani Hospital and an urban health center from August to November 2011. Content validity was evaluated by a panel of specialists after adding two religious items. The women completed the inventory and the demographic characteristics questionnaire in an interview room. The internal consistency and construct validity were assessed by Cronbach's alpha and by exploratory and confirmatory factor analyses, respectively. Known group analysis on gravity assessed the discriminant validity of the measure.
Content validity of the short form of the Iranian childbirth self-efficacy Inventory was confirmed. Factor analyses supported the conceptual two-factor structure of measure and hence supported its construct validity. The internal consistency was approved for the total scale and both subscales. The instrument differentiated prim gravid from multigravida women in the total scale and the efficacy expectancy subscale.
Validity and reliability of the measure supports the use of the short form of the instrument as a clinical and research instrument in measuring childbirth self-efficacy among Iranian pregnant women.
为了评估产妇应对分娩的信心，需要一种衡量分娩自我效能的方法。
本文旨在评估伊朗孕妇分娩自我效能量表简版的文化适应性和心理测量测试。
在这项描述性方法研究中，我们调查了383名孕晚期的伊朗孕妇。她们于2011年8月至11月从塔莱加尼医院的门诊产前保健诊所和一个城市健康中心招募而来。在添加两个宗教项目后，由一组专家评估内容效度。这些女性在一间访谈室完成了量表和人口统计学特征问卷。分别通过克朗巴哈系数以及探索性和验证性因素分析评估内部一致性和结构效度。基于重力的已知组分析评估了该测量方法的区分效度。
伊朗分娩自我效能量表简版的内容效度得到证实。因素分析支持了该量表概念上的两因素结构，从而支持了其结构效度。总量表和两个子量表的内部一致性均得到认可。该工具在总量表和效能期望子量表中区分了初产妇和经产妇。
该测量方法的效度和信度支持将该量表简版用作测量伊朗孕妇分娩自我效能的临床和研究工具。
