The present study was conducted to design and measure psychometrics of mothers' lifestyle scale during pregnancy with regards to Iranians' cultural norms and an approach to social determinants.
this study, started by reviewing previous studies and exploring similar questionnaires that examine different domains of lifestyle (nutrition, exercising, self-care, smoking, using alcohol and illegal drugs, social relations, and stress control), then besides translating questions of the questionnaires , content of some questions was modified and proper statements with regards to social determinant of health and Iranian cultural was used. Secondly, the validity of the designed instruments was determined using face, content, criterion, and construct validity. Thirdly, the reliability of the measurement instruments was examined using Cronbach's alpha. Participants were Healthy Iranian pregnant women (37-42 week) who refer to selected hospital for delivery.
In the first step of the study, of the 222 questions obtained from a review of the related instruments, certain questions were omitted due to their irrelevance to social determinants of health and finally 160 questions were selected in 10 sections. After determining the face and content validity qualitatively and quantitatively and exploratory factor analysis, the number of questionnaire items was reduced to 132. Calculation of Cronbach's alpha confirmed the high internal consistency (0.76) of the questionnaire.
This measurement instrument was designed in the context of the Iranian culture and sounded suitable for studying the pregnant women's lifestyle due to its appropriate validity and reliability, simplicity, and functionality in different situations.
本研究旨在根据伊朗文化规范及社会决定因素研究方法，设计并测量孕期母亲生活方式量表的心理测量指标。
本研究首先回顾以往研究并探索考察生活方式不同领域（营养、锻炼、自我护理、吸烟、饮酒及使用非法药物、社会关系和压力控制）的类似问卷，然后除了翻译问卷问题外，还对部分问题的内容进行了修改，并使用了与健康的社会决定因素和伊朗文化相关的恰当表述。其次，通过表面效度、内容效度、效标效度和结构效度来确定所设计工具的效度。第三，使用克朗巴哈系数检验测量工具的信度。研究对象为到选定医院分娩的健康伊朗孕妇（孕37 - 42周）。
在研究的第一步，从相关工具回顾中获得的222个问题中，一些与健康的社会决定因素无关的问题被剔除，最终在10个部分中选定了160个问题。在定性和定量确定表面效度和内容效度并进行探索性因素分析后，问卷项目数量减少到132个。克朗巴哈系数的计算证实了问卷具有较高的内部一致性（0.76）。
该测量工具是在伊朗文化背景下设计的，因其具有适当的效度和信度、简单性以及在不同情况下的功能性，似乎适合用于研究孕妇的生活方式。
