Summary
This study validated the Childbirth Self-Efficacy Inventory (CBSEI) in Australian women, finding prior birth experience and knowledge significantly impact childbirth self-efficacy. The inventory showed high reliability, though factor analysis revealed distinct coping strategies rather than distinct labor stages.
Area of Science:
- Obstetrics and Gynecology
- Psychology
- Health Sciences
Background:
- Childbirth self-efficacy is crucial for women's birth experiences.
- The Childbirth Self-Efficacy Inventory (CBSEI) is a key measure, but its psychometric properties require validation in diverse populations.
- Understanding factors influencing self-efficacy is vital for developing effective childbirth education and support.
Purpose of the Study:
- To examine the reliability and validity of the Childbirth Self-Efficacy Inventory (CBSEI) in a sample of Australian women.
- To test the predictive validity of the CBSEI based on self-efficacy theory, assessing the influence of parity, knowledge, support, and anxiety.
- To determine if the original factor structure of the CBSEI is applicable to Australian women through factor analysis.
Main Methods:
- Administered the Childbirth Self-Efficacy Inventory (CBSEI) to 100 Australian women.
- Assessed internal consistency and conducted factor analysis to evaluate the instrument's structure.
- Applied self-efficacy theory to analyze the influence of parity, knowledge, support, and anxiety on childbirth self-efficacy.
Main Results:
- The CBSEI demonstrated high internal consistency, consistent with previous US data.
- Prior positive birth experience and knowledge about childbirth significantly predicted higher childbirth self-efficacy.
- Factor analysis indicated that Australian women did not differentiate between active and second-stage labor, revealing two externally focused coping strategies instead of the original factor structure.
Conclusions:
- The Childbirth Self-Efficacy Inventory (CBSEI) is a reliable and valid measure for Australian women.
- Childbirth self-efficacy is significantly influenced by prior birth experiences and knowledge.
- The factor structure of the CBSEI may differ across cultures, highlighting the importance of culturally adapted assessments and interventions.
