Young
adults who had been criticized, insulted or threatened by a parent
growing up were more likely to be anxious or depressed, in a new study.
Even
when the same or another parent expressed plenty of affection,
researchers found the apparent harmful effects of having a verbally
aggressive mother or father persisted.
"There's a fair amount of
data out there that says that parental verbal aggression toward a kid is
very damaging," Byron R. Egeland said.
"In many instances, people find it to be as damaging as actual physical abuse," he told Reuters Health.
Egeland
has studied child maltreatment and development at the University of
Minnesota in Minneapolis and was not involved in the new research.
Past
research has linked verbally aggressive parenting to changes in
children's brain development and to personality disorders later in life,
researchers led by Ann Polcari write in the journal Child Abuse &
Neglect.
Polcari, from Northeastern University in Boston, and her
colleagues wanted to see whether also receiving affection from parents
would lessen those impacts.
Their study included about 2,500 young
people, ages 18 to 25. They each took a series of online surveys as
part of being screened for in-person tests and interviews for other
research.
Participants reported both on their current mental health and wellbeing and on their experiences with their parents growing up.
They
rated each of their parent's verbal aggression on a scale from zero to
105, based on how often mothers or fathers yelled at, scolded, insulted
and blamed them as kids. More verbally aggressive parents got higher
scores.
Study participants gave their mother's verbal aggression an average score of 22. They scored fathers between 26 and 29.
Verbal
affection was measured from zero to 84, with higher scores reflecting a
parent who expressed more affection and engaged in more meaningful
conversations with the child.
Participants scored their mothers between 65 and 66 on that scale, on average, and their fathers between 54 and 55.
Young
adults tended to have more psychiatric symptoms like anxiety and
depression when either their mother or their father was verbally
aggressive.
What's more, although having a verbally affectionate
parent seemed to have a positive impact on young people's wellbeing, it
didn't make up for having a second parent who was verbally aggressive,
Polcari's team found.
And having one parent who was both
affectionate and aggressive wasn't any better for a young person's
psychiatric health than if that parent was only aggressive.
"It isn't as if one cancels the other," Timothy Moore, from York University in Toronto, told Reuters Health.
"Whatever
the benefits of positive expressions may be, the negative association
between verbal aggression and adjustment persisted," Moore said. He has
studied the effects of verbal aggression in childhood but wasn't
involved in the new study.
"It certainly is important that there be somebody there that the kid can count on, starting at an early age," Egeland said.
"But
a large amount of verbal abuse or for that matter having a parent who
is emotionally unavailable or physically abuses the kid - those kids
will grow up with the idea that they can't count on others. Those are
kids that oftentimes don't benefit from the support of a neighbor or
coach or relative," he said.
"If the abuse starts at a very early age, it's likely that kid is not going to have trust in much of anybody."
Egeland
said the fact that verbal aggression is more common in poor families
means children who experience it are also more likely to have single
parents and lower quality schools - compounding their risks.
One
limitation of the study, the researchers noted, is that participants
recalled their parents' verbal aggression from years earlier to the best
of their memories. They also reported their own symptoms and weren't
checked by a doctor for psychiatric illness.
