Method: Maternal postpartum depression was assessed by the EPDS, and the Bayley-III was used to measure the children’s gross and fine motor abilities. Results: Both gross and fine motor scores were significantly higher for children whose mothers experienced postpartum depression than those who did not. Conclusion: The development of a child’s gross and fine motor skills is influenced by maternal postpartum depression, although not in the expected direction. Results indicated that both gross and fine motor scores were higher for children whose mothers had postpartum depression than those whose mothers did not. There was a significant difference in mean gross motor scores for children with mothers who experienced postpartum depression (M = 10.09, SD = 2.83) as compared to those who did not (M = 8.33, SD = 2.98), F (148) = 7.00, p = 0.009. Similarly, there was a significant difference in mean fine motor scores for children with mothers who experienced postpartum depression (M = 11.09, SD = 3.18) as compared to those who did not (M = 9.06, SD = 3.02), F (148) = 8.58, p = 0.004. Background & Population 8.33 10.09 Background: Previous research has indicated that children with depressed mothers score lower on tests of motor skills than children with non-depressed mothers (Field et al., 2001). Additionally, relatively high rates of motor development delays are associated with maternal depression (Cornish et al., 2005). Sample Population: 148 pregnant women (n = 148) receiving prenatal care at either Mount Sinai Hospital or New York Hospital Queens’ OB/GYN clinic were recruited to participate in the longitudinal study of pregnancy (P.I. Yoko Nomura). Gross Motor Larger movements of the body using arms, legs, or the entire body Fine Motor Smaller actions such as grasping an object between the thumb and a finger Discussion Method Maternal postpartum depression did not negatively impact child’s development in gross and fine motor skills; in fact, it resulted in increased motor abilities. While the relationships observed was in the opposite direction than expected, this may be due to the small sample size (n=148). Greater research with larger sample sizes are required to further understand the relationship between postpartum depression and child motor development. Further researchers should investigate developmental trajectories of motor ability in children of mothers who experienced postpartum depression to determine whether skills in early childhood are observed throughout the lifespan. Future studies should investigate contributing factors to why higher gross and fine motor scores may be found in children of mothers who suffered from postpartum depression, such as parenting style in depressed vs. non-depressed mothers. Measures: Participants were administered the Edinburgh Postnatal Depression Scale (EPDS) to determine maternal depression status which was indicated by a score on the EPDS of 10 or above. The Bayley-III Scales of Infant Development were administered to children at 18- 42 months of age (M = 27 months SD = 7.71) to measure gross and fine motor ability. The raw scores were converted to scaled scores, which can be used to determine the child's performance compared with norms. Data Analysis: Two one-way ANOVAs were used to examine the association between maternal postpartum depression and the children’s gross and fine motor scores.
