| Background: Women’s experience and satisfaction with childbirth care are increasingly being
addressed by health care providers, managers, and policymakers. Due to need for a validated
special scale for assessing satisfaction of women with preterm birth, we aimed to translate and
adapt the first specific tool, Preterm Birth Experiences and Satisfaction Scale (P-BESS), into
Persian language and evaluate its psychometric properties.
Methods: A methodological and cross-sectional study was conducted in two tertiary levels of
maternal hospitals in Tabriz. The Iranian version of the scale was developed from the original
English version using forward-backward translation. After confirmation of its face and content
validity, the scale was completed by 201 women who had given birth prematurely.
Results: Exploratory factor analysis revealed three factors (staff professionalism and empathy,
confidence in Staff, information and explanations) with eigenvalues greater than 1, explaining
a total variance of 55.4%. Confirmatory factory analysis showed that the 17-item, three
factor model fitted the data well: the root mean square error of approximation 0.060. There
were moderate correlations between the total and sub-scales of Iranian P-BESS and overall
satisfaction (r = 0.45 to 0.66), as well as need for improvement (r = -0.46 to -0.61), which
confirm convergent validity. Internal consistency and test–retest reliability of the scale and its
sub-scales were satisfactory (α = 0.852 to 0.922, intraclass correlation coefficient; 0.83 to 0.92).
Conclusion: The Iranian version of P-BESS is a valid and reliable scale which can be used by
policy makers, managers, health care providers and researchers. |
