RESUMO
BACKGROUND AND PURPOSE: The purpose of this research was to evaluate the psychometric properties of a new instrument to measure mother-infant togetherness, Mother-Infant Togetherness Survey (MITS). METHODS: Stage 1 examined content validity. Stage 2 pretested the readability and understandability and further examined content validity. Stage 3 examined women's ability to accurately self-report on the Delivery Events subscale. Stages 4 and 5 examined construct validity. RESULTS: Good content validity was obtained at the scale/subscale level (CVI = .91-1.00). Internal consistency reliability was evaluated at the scale/subscale level (α = .62-.89). Construct validity was supported with known groups testing and factor analysis. CONCLUSION: Study findings provide support for the reliability and validity of the MITS. Future research should be done to improve the internal consistency reliability of the Postpartum Events subscale.
