Adolescent Callous-Unemotional Traits and Parental Knowledge as Predictors of Unprotected Sex Among Youth.
Teen perception of parental knowledge—not parent report—drives safer sex choices, and the effect flips for low-callous youth.
01Research in Context
What this study did
McCauley et al. (2016) asked 265 high-school teens to fill out anonymous surveys.
The surveys measured callous-unemotional traits, how much parents knew about their lives, and whether they had ever had unprotected sex.
Parents also rated how much they thought they knew.
The team then looked at which kind of parental knowledge best predicted safer choices.
What they found
When teens believed their parents knew a lot, odds of unprotected sex dropped sharply.
Parent-only knowledge helped only for teens high in callous-unemotional traits.
If the teen scored low on those traits but the parent claimed high knowledge, risk actually rose—showing a knowledge gap can backfire.
How this fits with other research
Enav et al. (2020) also found parent factors matter, but showed parental stress—not knowledge—changes how moms and dads parent.
The two studies line up: parent variables shape teen outcomes, yet the active ingredient differs (knowledge vs. stress).
Marsack et al. (2017) looked at risky behavior in youth with mild intellectual disability and found life-skills classes lowered it.
Long et al. extend that idea to neurotypical teens: knowledge acts like a built-in life-skills lesson that cuts risk.
Together the papers say: boost parent input, but tailor the form to the teen you have.
Why it matters
You can ask teens directly, "How much do your parents really know?" If the answer is "not much," teach parents to ask open questions and share daily check-ins.
For teens who show little guilt or empathy, push parent monitoring apps or shared calendars—structure beats conversation.
For warm, rule-following teens, close the knowledge gap first; otherwise parent bravado can backfire.

03Original abstract
Risky sexual behavior among adolescents is common and results in many negative consequences. The present study investigated longitudinal predictors of adolescents' likelihood of engaging in unprotected sexual intercourse. Parental knowledge, or the extent to which parents know about their children's activities, whereabouts, and friendships, is a robust predictor of youth risk behavior, including risky sexual behavior. However, parenting practices are typically less potent as predictors of subsequent behavior among youth with high levels of callous-unemotional (CU) traits. We conducted three logistic regression models, each of which examined parental knowledge in a different way (through child report, parent report, and a discrepancy score), allowing us to examine parental knowledge, CU traits, and their interaction as predictors of adolescents' subsequent engagement in sex without a condom. Results indicated that adolescents who perceived their parents to possess greater knowledge were less likely to engage in unprotected sex. Higher parent report of parental knowledge was also related to decreased likelihood of engaging in unprotected sex, but only for adolescents with high levels of CU traits. In addition, greater discrepancy between parent and adolescent reports of parental knowledge was related to increased likelihood of engaging in unprotected sex, but only for adolescents with low levels of CU traits. Results highlight the importance of considering both parent and adolescent perceptions of parental knowledge and have important implications for prevention and intervention efforts.
