RESUMO
BACKGROUND: The emotional bond that a mother senses to her infant is essential to their social, emotional, and cognitive development. Understanding the level of mother-infant bonding plays an imperative role in the excellence of care. However, in Lebanon, there is a paucity of information about mother-infant bonding in the postpartum period. Given that Lebanese pregnant women constitute an important part of the population to look at, the objectives of the study were to (1) validate the Arabic version of the mother-infant bonding scale and (2) the relation between mother-infant bond and postpartum depression/anxiety; (3) the moderating effect of child abuse in the association between mother-infant bond and postpartum depression/anxiety. METHODS: This cross-sectional study was conducted from September 2022 until June 2023, enrolling 438 women 4-6 weeks after delivery (mean age: 31.23 ± 5.24 years). To examine the factor structure of the mother-infant bond scale, we used an Exploratory-Confirmatory (EFA-CFA) strategy. To check if the model was adequate, several fit indices were calculated: the normed model chi-square (χ2/df), the Steiger-Lind root mean square error of approximation (RMSEA), the Tucker-Lewis Index (TLI) and the comparative fit index (CFI). RESULTS: EFA was conducted on the first subsample. Three items were removed. The five items remaining loaded on one factor, which explained 73.03% of the common variance (ω = .91 / α = .90). After adding a correlation between residuals for items 2-7 and 5-8, fit indices of the CFA results were acceptable: χ2/df = 6.97/3 = 2.32, RMSEA = .068 (90% CI .001, .135), SRMR = .017, CFI = .996, TLI = .988. The interaction maternal-infant bonding by child psychological abuse was significantly associated with depression and anxiety respectively. At low, moderate and high levels of child psychological abuse, higher maternal-infant bonding scores (greater difficulty in bonding) were significantly associated with higher depression and higher anxiety respectively. CONCLUSION: This study provides, for the first time, a specific Arabic scale to assess mother-infant bonding reliably and validly. Furthermore, our study has suggested the existence of factors that have additive effects in potentiating the risk for depression and anxiety among Lebanese postpartum women, namely a history of psychological child abuse. Therefore, laborious awareness programs and healthcare services need to be implemented in order to prevent maternal mental health disorders from being unrecognized and left untreated.
