Web Desk: A recent study revealed that mother’s depression could lower the children’s IQ, negatively affect their cognitive development up to the age of 16.
University of California surveyed about 900 healthy children and their mothers living in Santiago, Chile at five-year intervals from the child’s infancy through age 16.
They studied how affectionate and responsive mothers were to their children at each age period, as well as how much mothers provided age-appropriate learning materials.
They also took standardized IQ tests during each assessment. Mothers were also tested for symptoms of depression.
The research scientists quoted, “We found that mothers who were highly depressed didn’t invest emotionally or in providing learning materials to support their child, such as toys and books, as much as mothers who were not depressed. This, in turn, impacted the child’s IQ at ages 1, 5, 10 and 16.”
“The consistency and longevity of these results speak to the enduring effect that depression has on a mother’s parenting and her child’s development,” they added.
On a scale from one to 19, the average verbal IQ score for all children in the study at age 5 was 7.64. Children who had severely depressed mothers were found to have an average verbal IQ score of 7.30 compared to a score of 7.78 in children without depressed mothers.
