From the Penn State press release:
Healthy relationships with their parents are vital for adolescents’ development and well-being, according to Penn State researchers who say rejection from fathers may lead to increases in social anxiety and loneliness.
The study — conducted by Hio Wa “Grace” Mak, doctoral student of human development and family studies — examined how parental rejection, as well as the overall well-being of the family unit, were related to changes in adolescents’ social anxiety, friendships and feelings of loneliness over time. Mak worked with Gregory Fosco, associate professor of human development and family studies, and Mark Feinberg, research professor of health and human development, at Penn State’s Prevention Research Center.
The researchers found that adolescents whose fathers were more rejecting tended to have more social anxiety later on, and in turn experienced more loneliness.
“We found that father rejection predicted increases in adolescents’ social anxiety, even when we controlled for social anxiety at an earlier time. In turn, this predicted increases in loneliness later on,” said Mak. “This suggests that fathers’ rejecting attitudes toward their adolescent children may make them more nervous about approaching social situations, which in turn is related to more social isolation and feelings of loneliness.”
Forming and maintaining good relationships is essential to an adolescent’s well-being, according to the researchers. Previous studies have shown that adolescents with thriving social lives tend to be more psychologically healthy, while those that struggle with forming good friendships tend to perform worse academically and suffer from more depressive symptoms.
