The Stirling Antenatal Anxiety Scale (SAAS): Turkish validity and reliability study

Aims: To examine the psychometric properties of the Stirling Antenatal Anxiety Scale (SAAS), developed by Sinesi et al., which assesses the level of anxiety of pregnant women in the prenatal period, in the Turkish culture, and to conduct a validity and reliability study. Methods: This study had a methodological approach, with a cross-sectional and descriptive research design. Reporting was in accordance with the STROBE checklist. The sample included 160 pregnant women who were followed up in the maternity outpatient clinics of a public hospital and a private hospital in Istanbul. Data were collected face-to-face using a personal information form, the Turkish version of the SAAS, and the Generalized Anxiety Disorder-7 scale between June and August 2023. In the data analysis, validity analyses were performed with content and construct validity and multiple fit indices for confirmatory factor analysis. Item-total score analysis was conducted using Cronbach's alpha coefficient and Pearson's correlation analysis to assess reliability. Descriptive and reliability analyses were undertaken using SPSS v.28.0.1.0, and validity analyses were performed using SPSS AMOS v.26.0.0.0. Findings: Based on expert opinions on the items in the Turkish version of the SAAS, the content validity ratio was 0.96. The decision was made to exclude Item 9 from the Turkish version because the item factor load was low. The Turkish version had a single factor, as did the original version. The Cronbach alpha coefficient was 0.87, so the Turkish version was determined to have high reliability. Conclusion: The Turkish version of the SAAS, originally produced in English, has high levels of validity and reliability. In addition, it is short and easy to apply in clinical and research settings. As such, the Turkish version of the SAAS is recommended for use to evaluate the level of anxiety in pregnant women.
