Gender dissonance: A novel metric and its associations with mental health across development
This study introduces "gender dissonance" as a novel metric derived from the ABCD Study to measure the gap between felt and expressed gender, finding that higher scores in gender-diverse youth are longitudinally associated with increased mental health struggles, including internalizing and externalizing symptoms, suicidal ideation, and autistic traits.

For many children, the journey of growing up involves a quiet, internal negotiation between who they feel they are and how the world expects them to behave. This is especially true for gender, a concept that often feels like a fixed label assigned at birth, yet for some, it feels like a fluid experience that shifts and changes over time. While society has long understood that some people identify as transgender—meaning their internal sense of self does not match the sex they were assigned at birth—scientists have struggled to track how this feeling develops in young children. The challenge lies in measuring something so personal and internal without relying on complex medical diagnoses or asking questions that young minds might not yet be ready to answer. Understanding this development is crucial because children who feel a deep disconnect between their inner identity and their outward life face significantly higher risks of depression, anxiety, and self-harm. To help these vulnerable youth, researchers need a way to spot the early signs of this struggle, even before a child can clearly articulate their identity.
A team of researchers at the National Institute of Mental Health and the University of Hartford has taken a significant step toward this goal by analyzing data from a massive, long-term study of American children. They focused on a group of nearly 12,000 children who were first surveyed at age ten and followed up annually until they were fourteen. The original study, known as the Adolescent Brain Cognitive Development study, did not have a direct way to measure gender confusion or distress, but it did ask children a series of questions about how they felt and how they played. The researchers realized that by comparing these answers, they could create a new way to measure the gap between a child's internal feelings and their external actions. They called this gap "gender dissonance." It is a simple but powerful concept: if a child feels deeply like a boy but plays with toys or dresses in ways typically associated with girls, there is a distance between those two things. The researchers built a score to measure that distance, ranging from perfect alignment to a wide gap, and then watched how that score changed as the children grew older.
The results of this analysis revealed a clear and concerning pattern. Children who identified as gender diverse—those who answered "yes" or "maybe" when asked if they were transgender—showed much larger gaps between their feelings and their actions than their peers. More importantly, these gaps were not static; they shifted and changed more dramatically over the four years of the study for gender-diverse youth than for children who felt their identity matched their assigned sex. The researchers found that a larger gap, or a rapidly changing gap, was strongly linked to poorer mental health. Children with higher scores of this dissonance reported more symptoms of anxiety and depression, as well as more behavioral issues. They were also significantly more likely to have thoughts of suicide, to make plans to end their lives, or to have attempted suicide. The data suggested that the more a child's internal world and external behavior seemed out of sync, and the more that mismatch fluctuated over time, the greater their risk for severe emotional distress.
One of the most striking findings was how this played out differently for children assigned male at birth versus those assigned female at birth. Children assigned female at birth showed much more variation in their gender feelings and expressions over time, while those assigned male at birth tended to stay more consistent, often showing no gap at all between their feelings and their play. This aligns with broader social observations that boys often face harsher criticism for stepping outside traditional gender roles, which might pressure them to hide their true feelings or conform strictly to expectations. The study also uncovered a strong link between this gender mismatch and symptoms of autism, suggesting that the two experiences often overlap in the lives of these children. However, the researchers noted a limitation in their method: their calculation relied on a binary view of gender, meaning it might miss children who feel they are somewhere in between boy and girl, as those children might show no "gap" even if they are experiencing significant internal conflict.
Despite these limitations, the study offers a promising new tool for understanding the mental health of gender-diverse youth. By treating the difference between feeling and expression as a measurable quantity, the researchers provided preliminary evidence that this metric can predict who is struggling. The findings suggest that the instability of this mismatch, rather than just the existence of it, is a key indicator of risk. For doctors and parents, this implies that paying attention to how a child's sense of self evolves over time, and how that sense aligns with their behavior, could help identify those in need of support long before a crisis occurs. While the researchers caution that this measure needs further validation and refinement, the work provides a concrete, data-driven way to see the invisible struggles of children navigating their identities, offering a path toward earlier and more effective care.
