Aim The aim of this study was to design and validate the fear of childbirth scale in women of reproductive age in Iran. Design Exploratory sequential method. Methods In this research, the initial items were formed after conducting 26 interviews and a systematic review of domestic and international databases. Validation of the scale was done on 927 women from Kahnuj city. After stating the goals and ethical issues of the research by the researcher, validation data was collected from the participants. The procedure for each step is explained below: For face validity: participants were selected from the city of Kahnuj using the maximum diversity method. Data collection was done through face-to-face interviews (for qualitative face validity) and printed questionnaires (for quantitative face validity). For content validity: experts were selected from all over Iran. Finally, 12 experts (two midwives, two obstetricians, two reproductive health specialists, four counsellors, one psychiatrist and one psychometric specialist) evaluated the initial items. Data were collected through electronic questionnaires. For construct validity: 1- exploratory factor analysis: The participants were selected by a multi-stage sampling method. In this way, the researchers randomly selected two neighbourhoods from the city of Kahnuj. After randomly selecting one street from each selected neighbourhood, by referring to these two streets, samples were selected from existing houses by systematic sampling. Finally, 404 questionnaires (93% response rate) were received. 2- Confirmatory factor analysis: The participants were selected by a multi-stage sampling method. In this way, the researchers randomly selected two neighbourhoods from the city of Kahnuj. After randomly choosing one street from each selected neighbourhood, by referring to these two streets, the necessary sample of the houses of these two streets was selected by systematic sampling method. Finally, 273 questionnaires (91% response rate) were received. For concurrent validity: The participants were selected by a multi-stage sampling method. In this way, the researchers randomly selected a neighbourhood from the city of Kahnuj. After randomly choosing a street from this neighbourhood, the necessary sample of the houses on this street was selected by systematic sampling. Finally, 100 written questionnaires (Shahrzad Sanjari, Soleimani, & Keramat, 2023) were collected. For reliability: The participants were selected by a multi-stage sampling method. In this way, the researchers randomly selected a neighbourhood of the city of Kahnuj. After randomly selecting a street from this neighbourhood, 130 samples of the houses on this street were selected by systematic sampling. This study considered participants 1 to 100 to assess internal consistency reliability and participants 101 to 130 to assess consistency reliability. data analysis was done with SPSS22 and Laserl8.8 software.
