Summary: This study aimed to update the assessment of construct validity and reliability of the Brazilian version of the Maternal-Fetal Attachment Scale (MFAS). This is part of a cohort study, in which the scale was applied to 415 pregnant women. The factor structure was verified via structural equation models. Comparative fit index (CFI), Tucker-Lewis index (TLI), and root mean square error of approximation (RMSEA) were used to verify the model fit. Additionally, to test the validity of the MFAS based on external variables, generalized linear model was performed to test the association between obstetric variables, social support, and symptoms of depression with the MFAS. The reliability was analyzed via the composite reliability coefficient (CR). The 12-item short version of the Brazilian MFAS showed adequate parameters of construct validity (CFI = 0.969, TLI = 0.960 and RMSEA = 0.032, 90%CI: 0.012-0.048) and is composed of three factors (“empathy and care”, “role-taking”, and “interaction with the fetus”) containing 12 items. The total scores of the MFAS were positively correlated with social support (p-value < 0.001) and negatively correlated with depressive symptoms (p-value = 0.007). Moreover, women who live with a partner (p-value = 0.026) and had intended pregnancies (p-value < 0.001) presented a better bond with the fetus. Regarding reliability, factors 1 and 2 showed adequate values (CR = 0.72 and CR = 0.82, respectively) and factor 3 regular value (CR = 0.63). This 12-item short version of the Brazilian MFAS may be a reliable and valid instrument for scientific studies and clinical assistance in Brazil.

Esta investigación es parte de un estudio de cohorte, en el que el instrumento se aplicó a 415 mujeres embarazadas. La estructura factorial se verificó mediante modelos de ecuaciones estructurales y se utilizaron el índice de ajuste comparativo (CFI), el índice de Tucker-Lewis (TLI) y la raíz de error cuadrado medio (RMSE) para verificar el ajuste del modelo. Además, para probar la validez de la MFAS en función de variables externas, utilizamos un modelo lineal generalizado para evaluar la asociación entre las variables obstétricas, el apoyo social y los síntomas de depresión con la MFAS. La confiabilidad se analizó mediante el coeficiente de confiabilidad compuesto (CC). La versión corta de 12 ítems de la MFAS brasileña presentó parámetros adecuados de validez de constructo (CFI = 0,969; TLI = 0,960; RMSE = 0,032; IC90%: 0,012-0,048) y está compuesta por tres factores (“empatía y cuidado”, “toma de papeles” e “interacción con el feto”) y 12 ítems. Las puntuaciones totales de MFAS se correlacionaron positivamente con el apoyo social (p < 0,001) y negativamente con los síntomas depresivos (p = 0,007). Además, las mujeres que viven con una pareja (p = 0,026) y tuvieron la intención de quedar embarazadas (p < 0,001) tienen un mejor vínculo. En relación con la confiabilidad, los factores 1 y 2 presentaron valores adecuados (CC = 0,72 y CC = 0,82, respectivamente) y el factor 3, un valor regular (CC = 0,63). Esta versión corta de 12 ítems del MFAS parece ser un instrumento fiable y válido para ser aplicado en la investigación científica y la atención clínica en Brasil.O objetivo deste estudo foi atualizar a avaliação da validade de construto e confiabilidade da versão brasileira da Escala de Apego Materno-Fetal (MFAS).

A versão curta de 12 itens da MFAS brasileira apresentou parâmetros adequados de validade de construto (CFI = 0,969; TLI = 0,960; RMSEA = 0,032; IC90%: 0,012-0,048) e é composta por três fatores (“empatia e cuidado”, “desempenhando um papel” e “interagindo com o feto”) e 12 itens. Os escores totais da MFAS correlacionaram-se positivamente com o suporte social (p < 0,001) e negativamente com sintomas depressivos (p = 0,007). Além disso, as mulheres que vivem com um parceiro (p = 0,026) e tiveram a intenção de engravidar (p < 0,001) têm melhor vínculo. Em relação à confiabilidade, os fatores 1 e 2 apresentaram valores adequados (CC = 0,72 e CC = 0,82, respectivamente) e o fator 3, um valor regular (CC = 0,63).
