Parental monitoring is linked to fewer teen conduct problems despite genetic risk

Rutgers Health–led research builds on decades of work showing that family and environmental factors interact with genetics to shape child development

2025-11-19

(Press-News.org) Parents may have more influence than they realize when it comes to shaping their children’s behavior, especially for those at higher genetic risk for conduct problems, according to Rutgers Health-led research.

The study, published in Frontiers in Child and Adolescent Psychiatry, found that consistent parental monitoring – meaning knowing where children are, who they’re with, and what they’re doing – can help offset genetic risk for developing behavior problems during adolescence.

Conduct problems, which include aggression, antisocial behavior and rule-breaking, often begin in childhood and are among the most common reasons youth are referred for mental health services. These behaviors are linked to long-term challenges such as substance use, school difficulties and justice system involvement.

“While genetics contribute to why some children are more likely to develop conduct problems, this study shows that parenting really matters,” said Maia Choi, a postdoctoral fellow at the Translational Psychiatric Genomics Lab at Rutgers Robert Wood Johnson Medical School and the lead author of the study. “High levels of parental monitoring appeared to buffer the influence of genetic risk – meaning that attentive, consistent parenting can make a measurable difference, even for children who are more vulnerable biologically.”

The study used data from more than 4,000 adolescents ages 12 to 14 participating in the Avon Longitudinal Study of Parents and Children, a long-term research project based in the United Kingdom. Researchers examined how genetic predispositions for behavioral disinhibition – tendencies toward impulsivity and rule-breaking – interacted with parental monitoring to predict conduct problems.

Researchers found adolescents with higher genetic risk for externalizing behaviors showed more conduct problems only when parental monitoring was low. When monitoring was high, genetic risk had a much smaller impact on behavior.

“This is a hopeful message for parents,” said Danielle Dick, director of the Rutgers Addiction Research Center based at Rutgers Brain Health Institute and the senior author of the study. “Genes are not destiny. The environment parents create – the structure, consistency and connection they provide – can play a powerful role in protecting youth at risk.”

The findings build on decades of work showing that family and environmental factors interact with genetics to shape child development. As noted in the scientific literature, only a small number of studies have tested polygenic score effects during early adolescence, making this analysis a notable contribution.

Researchers said the results highlight the importance of family-based prevention and early intervention programs. Strengthening parenting skills, especially around monitoring and communication, could help reduce the development of conduct problems and their long-term consequences.

“Adolescence is a critical window for intervention,” said Choi. “By supporting parents and helping them stay engaged, we can change trajectories for young people who might otherwise struggle.”

The study was co-authored by Rutgers researchers Genevieve Dash, Sally Kuo, Fazil Aliev, Holly Poore and Sarah Brislin.

Can AI help us predict earthquakes?

2025-11-19

Kyoto, Japan -- Predicting earthquakes has long been an unattainable fantasy. Factors like odd animal behaviors that have historically been thought to forebode earthquakes are not supported by empirical evidence. As these factors often occur independently of earthquakes and vice versa, seismologists believe that earthquakes occur with little or no warning. At least, that's how it appears from the surface. Earthquake-generating zones lie deep within the Earth's crust and thus cannot be directly observed, but scientists have long proposed that faults may undergo a precursory phase before an earthquake during which micro-fracturing and slow slip occur. ...

Teaching models to cope with messy medical data

2025-11-19

Hospitals do not always have the opportunity to collect data in tidy, uniform batches. A clinic may have a handful of carefully labelled images from one scanner while holding thousands of unlabelled scans from other centres, each with different settings, patient mixes and imaging artefacts. That jumble makes a hard task—medical image segmentation—even harder still. Models trained under neat assumptions can stumble when deployed elsewhere, particularly on small, faint or low-contrast targets. Assistant Professor Zhao Na from SUTD and collaborators set out to embrace ...

Professor Zaifa Shi's team at Xiamen University developed an ultra-high temperature flash vacuum pyrolysis (UT-FVP) device to form giant fullerenes from single-carbon molecules within a short time (15 s) at extremely high temperatures (∽3000 ℃). Due to the strong intermolecular forces between giant fullerene molecules and soot, traditional ultrasonic or Soxhlet extraction methods cannot separate most giant fullerenes from soot in toluene. To overcome these strong intermolecular forces, two ...

A ‘magic bullet’ for polycystic kidney disease in the making

2025-11-19

(Santa Barbara, Calif.) — Polycystic kidney disease (PKD) is a debilitating hereditary condition in which fluid-filled sacs form and proliferate in the kidneys. Over time, the painful, growing cysts rob the organs of their function, often leading to dialysis in advanced cases There is currently no cure. Researchers at UC Santa Barbara, however, have proposed a cyst-targeted therapy that could interrupt the runaway growth of these sacs by leveraging the target specificity of the right monoclonal antibodies — lab-made proteins that are used in immunotherapy. “The cysts just keep growing endlessly,” said UCSB biologist ...
