Introduction: Pregnancy-related stress has been extensively documented, however there is a limited availability of effective and simple questionnaire to assess stress during pregnancy. Given that elevated stress levels during pregnancy are linked to negative health outcomes for both mother and child, there is a critical need for reliable screening tools in clinical practice. This study aims to develop and evaluate the validity and reliability of a 12-item instrument designed to assess stress among pregnant women.
Methodology: The newly-designed stress scale was developed based on literature review, as well as adaptation and modification from other stress scales. A pilot study was conducted prior to the field study. Next, this questionnaire was distributed to 390 pregnant women, aged between 18- 45 years old, through email. The respondents were recruited among patients that visited antenatal clinic at Hospital Canselor Tuanku Muhriz Kuala Lumpur, Malaysia. Exploratory Factor Analysis (EFA) was conducted using data collected from 130 respondents and subsequently Confirmatory Factor Analysis (CFA) was conducted using the remaining data.
Result: EFA conducted using principal component extraction with Varimax rotation, identified a three-factor structure that accounted for 72.76% of the total variance. The instrument demonstrated excellent internal consistency, with a Cronbach’s alpha of .928. The Kaiser-Meyer-Olkin (KMO) value of .885 and a significant Bartlett’s test (χ² = 1130.582, p < .001) supported the adequacy of the data for factor analysis. CFA conducted to verify the factor structure, revealing moderate model fit indices: χ² = 353.8, df = 51, χ²/df = 6.93, GFI = 0.817, AGFI = 0.721, RMSEA = 0.151, NFI = 0.856, and CFI = 0.874.
Conclusion: This new stress scale has strong reliability and valid to be used as screening tool for stress. This scale serves as an alternative tool to evaluate stress during pregnancy, potentially contribute to effective outcome measures.
