Immigrant children in ‘tender age shelters’ at risk for psychological disorders

The practice of separating immigrant children from their parents is very likely to lead to negative effects on emotional and mental health, according to an invited paper in The Journal of Clinical Child and Adolescent Psychology penned by Vanderbilt University psychology professor Kathryn L. Humphreys.

“Exposing children to such high levels of stress puts them at an elevated risk for psychopathology in the future, including depression and anxiety.”

“Recent changes in the U.S. immigration system have resulted in a large number of children removed from their parents, drawing increased scrutiny to this abhorrent practice,” Humphreys said. “Exposing children to such high levels of stress puts them at an elevated risk for psychopathology in the future, including depression and anxiety, aggressive behaviors, attention-deficit/hyperactivity disorder, attachment disorders, language deficits and social difficulties.”

The youngest of these children, who have been detained in so-called “tender age” shelters, may be the most vulnerable to the stress of separation, according to Humphreys’ recent study published by Developmental Science. She finds that children who experienced stressful or traumatic experiences in their earliest years—birth to age 5—were found to have reduced hippocampal volume when they reached adolescence. Reduced HV is associated with memory issues, learning difficulties and depression.

“Many members of the lay public, public officials and even scientists perpetrate a pernicious belief that if children cannot remember something, it does not affect them. This could not be further from the truth,” Humphreys said. “Our research finds that infants and young children up to age 5 are particularly affected by experiences of stress and trauma. Children belong in families that are safe and supportive and substitute group-based care is insufficient to meet their emotional needs.”

The practice of separating immigrant children from their parents at borders as a deterrent is counterproductive, Humphreys said.

“Studies show that parents separated from their children due to immigration enforcement report
 an intention to return to the United States following deportation with a goal of reuniting with their children,” she said. “In other words, their love for their children motivated the seeking of safety and opportunities in a new country as well as the willingness to face detention to reunify with those separated children.”
