Reliability and validity testing of three breastfeeding assessment tools

Area of Science:

• Clinical Nursing
• Maternal-Child Health
• Infant Feeding Practices

Background:

• Effective breastfeeding is crucial for infant and maternal health.
• Accurate assessment tools are needed to identify and support breastfeeding dyads.
• Existing tools require rigorous validation for clinical application.

Purpose of the Study:

• To evaluate the validity and reliability of three common breastfeeding assessment instruments.
• To determine if the Infant Breastfeeding Assessment Tool (IBFAT), Mother Baby Assessment Tool (MBA), and LATCH tool meet clinical standards.
• To inform the development of more dependable breastfeeding assessment methods.

Main Methods:

• A descriptive correlational design was employed.
• Eleven breastfeeding mother-infant pairs were observed and videotaped.
• Three nurse raters assessed breastfeeding using the IBFAT, MBA, and LATCH tools twice, with a 6-month interval, analyzing interrater and test-retest reliability.

Main Results:

• Reliability coefficients for all three tools fell below acceptable levels for clinical decision-making.
• Interrater reliability correlations varied significantly (IBFAT: .57-.69; MBA: .33-.66; LATCH: .11-.48).
• Test-retest reliability also showed variability, and percent agreement among raters ranged widely (37.0%–97.2%).

Conclusions:

• The IBFAT, MBA, and LATCH tools, in their current form, are not sufficiently reliable or valid for clinical assessment of breastfeeding effectiveness.
• These instruments require substantial revision and revalidation.
• Improved tools are essential for accurately identifying mother-infant pairs needing breastfeeding support and intervention.
