Labor unit culture and attitudes toward supporting vaginal birth-The Swedish version of the labor culture survey (S-LCS)-Psychometric properties

BACKGROUND: In order to evaluate interventions aimed at reducing cesarean births, care practitioners' attitudes are important to measure. The Labor Culture Survey (LCS) is a scale that measures individual and unit attitudes towards supporting vaginal birth. As no equivalent scale exists in Sweden, the aim was to translate, adapt, and validate the LCS and to investigate whether there were differences in attitudes toward supporting vaginal birth between maternity care practitioners. METHODS: A cross-sectional study including midwives, physicians, and nurse assistants working with intrapartum care in five labor wards in Sweden. The original LCS was translated into Swedish, and six context-specific items were developed for the Swedish setting (SLCS). The translation was tested for face validity. Psychometric analysis was conducted using exploratory factor analysis with principal component analysis, parallel analysis, and principal axis factoring. Reliability was estimated using Cronbach's alpha. One-way ANOVA and Tukey HSD were calculated to analyze differences in attitudes between professions on the subscales of the S-LCS. RESULTS: A total of 539 midwives, physicians, and nurse assistants participated. The final S-LCS showed a five-factor solution with the following subscales: Best Practices to reduce cesarean overuse, Unpredictability of vaginal birth, Unit Microculture, Maternal Agency, and Organizational Oversight. Chronbach alpha values varied from 0.60 to 0.83. Midwives were more supportive towards vaginal birth and less fearful of potential consequences of vaginal birth compared with physicians. CONCLUSIONS: The S-LCS demonstrated satisfactory psychometric properties for use in Swedish maternity care. Further work to improve the scale should include additional items reflecting the subscale Maternal Agency.
