The Birth Satisfaction Scale-Revised Indicator (BSS-RI): a validation study in Iranian mothers

Birth Satisfaction Scale-Revised Indicator (BSS-RI) is a short selfreport instrument designed to measure satisfaction of the childbearing women's experiences of labour and its outcomes. The aim of this study was to examine the reliability and validity of the Persian version of BSS-RI in Iranian mothers.

This cross-sectional study was conducted on 396 mothers in Tehran, Iran, between July and September 2017. The mothers were administered the BSS-RI, and a demographic questionnaire. Internal consistency of the BSS-RI was examined with Cronbach's alpha, construct validity was evaluated via exploratory factor analysis (EFA), and divergent validity was examined by correlating the BSS-RI with gestational age.

The EFA results demonstrated a two-factor structure corresponding to the Stress of Childbearing and Quality of Care domains of the structure proposed by provider. The Cronbach's alpha for Stress of Childbearing and Quality of Care subscales and total BSS-RI were 0.665, 0.847, and 0.563, respectively. The mean of BSS-RI total score was 6.16 (SD = 2.60), and the Stress of Childbearing and Quality of Care subscales were 2.71 (SD = 2.39), and 3.45 (SD = 1.11), respectively. The BSS-RI showed no significant correlation with the gestational age, confirming divergent validity.

Like the original English version, the Persian version of the BSS-RI is a reliable and valid instrument for measuring birth satisfaction in Iranian mothers. It can also be used as short and easy to administer tool for assessment of birth satisfaction in large sample survey research.
