Persian version of the support and control in birth questionnaire among Iranian women
Journal of Education and Health Promotion
BACKGROUND: Lack of perceived support and control during labor and childbirth is known as an important predictor of post-traumatic stress disorder following childbirth. However, there is no standard scale to measure perceived support and control for Iranian women. This study determined the validity and reliability of the support and control in birth questionnaire for Iranian women. MATERIALS AND METHODS: Support and control in the birth questionnaire were translated into Persian by the forward and backward translation method in 2019. Among a total of 102 healthcare centers in Tabriz, 50 urban and 10 rural centers were selected randomly. Then, 660 women with vaginal childbirth during the postpartum period were extracted by each center and selected randomly. The validity of the Persian version was evaluated in terms of face, content, and construct validity. Internal consistency and reliability were assessed by Cronbach's alpha coefficient and intraclass correlation coefficient, respectively. Exploratory and confirmatory factor analyses were used for evaluating the construct validity of the tool. RESULTS: Cronbach's alpha coefficient (0.95) and intraclass correlation coefficient (0.99) were acceptable. In an exploratory analysis, three factors were extracted and these three factors explained 63.1% of the total variance. Items 14 and 17 were removed from the Persian version due to low factor loading and impact factor values. Confirmatory factor analysis supported the three factors extracted in the exploratory analysis. Confirmatory factor analysis showed suitable indexes of fitness for 31 items. CONCLUSION: Persian version of the support and control in the birth questionnaire is a valid and reliable tool for the Iranian women population.
