Casual sex linked to teen depression

CORNELL (US) — Teens who “hook up” have a higher risk of depression, according to new research that finds the same does not hold true for those in a committed relationship.

Casual sex increases a teenager’s odds for clinical-level depression nearly threefold. The effects are the same for boys and girls, though younger teens (13-15 years old) who had so-called “nonromantic sex” faced substantially greater risks for depression. Dating alone was not linked to depressive symptoms.

Published in the Journal of Abnormal Psychology, the the study provides evidence that “context is key” when trying to understand how teen relationships and sex affect their well-being.

“Many historical and media perspectives have presented adolescent sexuality as an indicator of problematic or even socially deviant behavior,” says Jane Mendle, assistant professor of human development in Cornell University’s College of Human Ecology. “But this study and other recent findings are showing that’s not the case, and adolescent dating and sexuality can be viewed as normal developmental behavior.”

Using a novel behavioral genetics approach that compares siblings growing up in the same home, Mendle and her co-authors analyzed responses from 1,551 sibling pairs ages 13-18 from the National Longitudinal Study of Adolescent Health, a nationally representative sample of US high school students initiated in the mid-1990s. Among other topics, teens answered questions about their mental health and dating and sexual history. Nearly two-thirds of the sample’s youth had dated, and two-thirds were virgins.

By comparing siblings in their study, the authors could control for family and environmental influences that might also raise one’s risk for depression.

“We designed the study to give us a purer way to isolate many of the factors that could be contributing to depression,” Mendle says. “It allows us to compare specific types of social activities—in this case, dating and romantic and nonromantic sex—to see their overall effect.”

The paper notes that not all the associations at play can be unraveled, however. For instance, some teens who have depressive symptoms or clinical depression may be more likely to engage in casual sexual behaviors.

Mendle, a licensed clinical psychologist who studies how such developmental processes as puberty and sexual maturation influence teens’ emotional growth, believes adolescent sexuality is important to study because it is closely tied to how well people transition into adulthood.

“One of the hallmarks of adolescence is the formation of romantic relationships, and we know that what happens in adolescence is strongly related to your psychological, physical and financial well-being for years to come,” Mendle says. “Findings like this can help shape the dialogue and public debate about how to best support teen sexual health, psychological development and other areas.”

Researchers from the University of Texas were co-authors on the study.
