​Identity Development

The importance of social identities in adolescence as an opportunity to promote positive adjustment

Adolescence is a key period for exploring and developing our sense of who we are. This includes our social identity, such as our ethnic-racial or sexual identity. In this paper, Adam Hoffman and Adriana Umaña-Taylor argue that the importance of social identity during adolescence can be an opportunity to promote positive adjustment—especially for youth with marginalized social identities. The authors highlight two specific interventions that effectively targeted social identity development and improved adolescent adjustment: the Identity project and the PRIDE project.

The Identity project was a weekly, school-based intervention in which mid-adolescent (about 15 years old) youth explored their ethnic-racial identity, with the opportunity to teach each other, reflect, and discuss. The program increased exploration of and clarity in the students’ ethnic-racial identity, which was in turn associated with higher levels of self-esteem, better academic outcomes, and lower symptoms of depression a year later. The PRIDE project was a short intervention aimed at affirming marginalized social identities amongst 9th graders, a transition year for many youth when self-esteem often begins to decline. The intervention–three sessions throughout the year for youth to write about one of their social identities, what they liked about it, and why–buffered against this developmental decline in self-esteem. By the end of the year, youth in the program showed higher self-esteem than their peers once the program was completed. (Child Development Perspectives, September 2023)

Why this is important: This paper draws upon successful real-world interventions to highlight the value of programs that support social identity exploration and affirmation in adolescence, especially for youth with marginalized social identities.

Effects of conflict at home and at school on the emotional health of gender nonconforming youth

Gender nonconformity—gender expression that differs from stereotypes based on sex assigned at birth—has been associated with elevated risk of emotional and behavioral health problems in youth due to higher rates of peer victimization and rejection by parents and peers. In a sample of 10,000+ 10- and 11-year-olds, Hannah Loso and colleagues examined how family conflict and perceptions of the school environment (that is, how safe and/or supported an individual feels at their school) might contribute to the association between gender nonconformity and emotional and behavioral health problems in youth. Youth with gender nonconforming presentations reported higher levels of conflict amongst family members, as well as poorer perceptions of their school environments; even further, family conflict and negative perceptions of the school environment partially explained the associations between gender nonconformity and mental and behavioral health problems amongst these youth. (Journal of Adolescent Health, June 2023)

Why this is important: This study demonstrates how gender nonconforming youth often face family and school conflict at a detriment to their mental and behavioral health, highlighting the potential value of school and family-based interventions such as anti-discrimination policies for schools or education and resources for parents to support their gender nonconforming children.

​Family and Peer Relationships

Strong family cultural values can moderate environmental effects on adolescent mental health

Family cultural values—such as those that emphasize family support, attachment, loyalty, respect, and obligation—can shape the home environment and influence emotional development. In this study, Gianna Rea-Sandin and colleagues examined whether family cultural values impact mental health and behavior in adolescence. In 10,000+ children and adolescents and their parents, greater parent- and youth-reported family cultural values at age 11 to 12 predicted fewer internalizing symptoms (such as anxiety and depression) and externalizing symptoms (such as rule-breaking behavior or aggression) at ages 12 to 13. In a subset of the sample that included 1,042 twin pairs, the authors found that shared and unshared environmental influences, but not genetic factors, accounted for the variance in internalizing symptoms over adolescence. Interestingly, higher levels of family cultural values decreased the role of unshared environment influences on internalizing symptoms amongst the twins, indicating the important role that supportive family environments can play in shaping healthy emotional development in adolescence. (Behavior Genetics, September 2023)

Why this is important: This study demonstrates that family cultural values such as respect and loyalty towards family can be a protective factor for mental health problems such as anxiety and depression in adolescence.

Parents and friends can influence emotion regulation abilities in adolescents

During adolescence, we are especially sensitive to our social environment. Feedback from those around us shapes how we process and regulate our emotions. Although friends become increasingly important in adolescence, parents are still key to emotional development during this time. In this study, Juan Wang and colleagues explored how feedback from friends, mothers, and fathers can facilitate or impede emotion regulation abilities in a group of 438 young adolescents (around 11 to 12 years old).

More supportive responses from friends were associated with better emotion regulation abilities a year later for both boys and girls, while parents’ responses showed uniquely strong effects in girls. Mothers’ supportive responses (such as asking why the child is unhappy or assuring them they don’t have to worry) explained additional emotion regulation abilities beyond friends’ responses, and fathers’ unsupportive responses (such as ignoring the child’s unhappiness or punishing the child) moderated the predictive power of friends’ responses on emotion regulation abilities a year later. This suggests that both parents and peers are important for regulating emotions in adolescence; further, parental support may enhance or decrease the positive effects of peer support, suggesting that even if adolescents rely on peers over parents for emotion regulation, parents can shape the influence of peer support on their child’s emotional development. (Journal of Youth and Adolescence, September 2023)

Why this is important: This study demonstrates that social relationships with both parents and peers are important for emotion processing and regulation in adolescence and underscores the value of both forms of social support for adolescent emotional development.

​Educational Settings

Exclusionary discipline practices in schools can increase the risk of legal system contact and substance use in adulthood

Exclusionary school discipline (suspension and expulsion) can break down social bonds, decrease school connectedness, and disrupt academic progress, which can increase the risk of problematic substance use and exposure to the criminal legal system. In this study, Seth Prins and colleagues examined associations between substance use and exclusionary school discipline in a group of 20,000+ high school students who were interviewed in the 1990s and early 2000s, when exclusionary discipline practices and school-based arrests increased sharply in the United States. The authors also tested how adolescent substance use and exclusionary school discipline predicted likelihood of being arrested in adulthood (ages 24 to 32 years old).

Students who reported substance use were more likely to experience school discipline over the following years, and students who reported exclusionary school discipline were more likely to report substance use in the following years. Youth who reported substance use and exclusionary school discipline in adolescence were also more likely to use substances and to be arrested as adults. (Drug and Alcohol Dependence, October 2023)

Why this is important: This study demonstrates that exclusionary school discipline practices can contribute to substance use and future entrance into the criminal legal system, highlighting schools as crucial contexts for investment in interventions to support healthy outcomes instead of exclusionary punishments.

School engagement in adolescence predicts positive adult outcomes

In this study, Jennifer Symonds and colleagues used data from 13,135 individuals studied over 40 years of life to investigate how school engagement in adolescence relates to educational and employment outcomes in adulthood. Students were interviewed at age 16 regarding their level of school engagement—measured by how much they enjoyed school, felt school was a good use of time, and were willing to help and participate at school. Over a decade later, at ages 34 and 46, these same individuals were interviewed regarding their employment outcomes. Higher levels of school engagement at age 16 predicted higher educational achievement and income levels in adulthood, even when controlling for relevant demographics such as childhood socioeconomic status and cognitive ability. (Developmental Psychology, March 2023)

Why this is important: This study shows that engagement in school and school activities in adolescence can have a persistent, positive impact on adult outcomes, highlighting the importance of fostering engagement in schools for healthy adolescent development.

The Connecting Adolescent Brain

Fact Sheet

This fact sheet gives an overview of adolescent brain development and explains how access to resources, opportunities, and meaningful relationships during adolescence can build connections within our brains and with the world around us that support us into adulthood.

Brain development during adolescence is fundamentally a story of connections.

Around age 9 or 10, hormonal changes kick off a period of intense learning and development, when brain cells form, strengthen, and streamline connections in response to our experiences more rapidly than in any period of life after early childhood.

Activity increases especially in the brain networks that propel us to explore the world, learn from our mistakes, and connect with others in new ways. In turn, these new experiences prompt our brain cells to connect with other neurons in ways that help us adapt to new events and new information. These neural connections become stronger the more we use them, while unused connections are pruned away, helping the brain become more efficient at acquiring and mastering new skills and new ways of thinking.

This brain-building learning happens through direct experiences in our environments and interactive, responsive relationships—with our families and peers, in our classrooms and neighborhoods, in community activities, and even online. The resources, opportunities, and experiences we as adults provide in and out of school can help young people’s brains build the extensive networks of connections that will manage the complex knowledge and behaviors needed to navigate adulthood.

Learning by Exploring the World Around Us

One of the networks that changes significantly with the increase in hormones and dopamine at the beginning of puberty is the “reward system” in our brain. Heightened activity in this system increases the feeling of reward we get from exploring the world, taking risks, and learning from the results.

Meanwhile, the network of brain regions that make up the “social brain” also changes during adolescence. These changes help us tune into social and emotional cues, like facial expressions or social rejection and approval, and increase our desire to earn respect and contribute to others. It also enables us to learn the nuances of changing social contexts in ways that help prepare us for adult relationships.

The prefrontal cortex (the region of the brain that orchestrates critical thinking and behavioral control) undergoes its most rapid period of development during adolescence. It builds on many other systems within the brain to manage our responses to the flood of new information and intensifying emotions. Engaging with other people and our environment and learning from our successes and our mistakes, known as “action-based learning,” helps shape the prefrontal cortex by strengthening the connections within it and between it and other brain networks. We learn through repeated practice—which includes trying and sometimes failing—what is adaptive and appropriate in different situations and how to guide our behavior accordingly, in ways that equip us to pursue new forward-looking goals.

When adults provide youth with opportunities to try new things, to practice navigating emotions, and to learn from failures along the way, it helps build the brain connections that we all need to grow into healthy, thriving adults.

Policies, Experiences, and Mindsets Shape the Connecting Brain

Although we can continue to learn new skills and behaviors as adults, the adaptability of the brain during adolescence means that these connections are much more likely to form quickly in response to experiences. The extent of these changes make the adolescent years a critical window when investments in the right policies and programs for youth can shape long-term positive development.

Likewise, this makes the adolescent years a time when negative experiences including racism, other forms of discrimination, poverty, or abuse can create steeper hills for young people to climb toward a healthy adulthood. When adults ensure that all young people, especially those who have experienced earlier adversity, have what they need along their journey, they can build the skills and capacities they need to thrive as adults. This includes opportunities to explore and take healthy risks, to connect with and contribute to those around us, to make decisions and learn from the outcomes, to develop a healthy sense of identity, and to rely on support from parents or other caring adults.

Understanding how and why the brain develops during adolescence lets us provide the support young people need to build healthy connections—in their world and within their brains—that will help our youth and our communities thrive.

Engaging, Safe, and Evidence-Based: What Science Tells Us Adolescents Need When Online

Council Report | Education | Mental Health | Digital Tech

This council report from the National Scientific Council on Adolescence offers research-based suggestions for policymakers and technology companies to ensure that digital tech used by middle-school-aged youth promotes positive development and keeps young users safe online.

Early adolescence—roughly ages 10 to 13—is a key time of exploration, discovery, rapid learning, and social and emotional change. It is also the point when many young people begin spending time in a larger online world.

Digital technology is not all good or all bad, but during early adolescence, its effects can be amplified. We now know enough from research on brain and social development and about the impacts of technology during these years that we can recommend standards and regulations for digital tech used by this age group that can support and protect our young people.

A new report from the National Scientific Council on Adolescence (NSCA) outlines the benefits and risks of digital technology during these years and offers specific suggestions for ways digital tech used by early adolescents can:

  • Support healthy development and wellbeing
  • Keep young users safe
  • Incorporate and advance the best available research
  • Provide access to positive learning to all young adolescents

Report authors Nick Allen, Ron Dahl, Jacqueline Nesi, and Candice Odgers talk with report lead Jennifer Pfeifer about the benefits and risks of digital technology during early adolescence, and how research-informed standards and regulations could support and protect youth online.

Key Developmental Needs of Adolescence

Fact sheet | Education | Community Engagement | Mental Health | Out-of-School Time | Foster Care | Juvenile Justice

​This fact sheet gives a summary of six key developmental needs that research tells us are critical to healthy development during our adolescent years.

Research into adolescent development points to core developmental needs during our adolescent years. These key developmental needs of adolescence include:

Explore the world and test out new ideas and experiences

Heightened activity in the “reward center” of our brain during adolescence increases our motivation to try new things and explore the world, which help us discover who we are, expand our skills, and ultimately leave the familiarity of home. Policies and programs that provide opportunities for healthy risk taking help youth channel these tendencies in ways that support positive development.

Developing meaning and purpose through contribution

During adolescence, we’re increasingly able to support others in deeper, more meaningful ways than when we were younger. Experiences in which we make a positive difference help us develop a sense of meaning and purpose, which support wellbeing, academic success, and resilience. Policies and programs should ensure all young people have opportunities to contribute.

Build decision making and emotional regulation skills

Our cognitive and emotional abilities mature during adolescence in ways that help us develop new skills related to making good decisions and navigating our emotions. We continue to build these skills as we practice in real-world situations with support to make and learn from mistakes. Supportive adults should provide them with opportunities for increasing agency in decisions that impact their lives.

Support from Parents and Other Caring Adults

Secure and supportive relationships with caring adults when we’re adolescents are essential to our physical and mental health, helping us build resilience, develop a positive sense of self, and form a positive racial and ethnic identity. Programs and policies can help prioritize strong family bonds and provide mentors for youth.

Developing Values, Goals, & Identity

During adolescence, our relationships, experiences, and the messages we receive about our racial, gender, and other identities help us form a positive sense of identity and belonging. Policies and programs that provide opportunities to explore roles and activities can help youth discover what they value, who they are, and who they want to become.

Find a respected role among peers and adults

Changes in our brain and our social settings during adolescence increase our social awareness and motivate us to learn the skills we need for the more complex social demands of adulthood. These changes also amplify the impact of discrimination. Policies and programs can ensure that all young people have ample positive pathways to gain respect.

Get sufficient sleep to support mental and physical well-being

Extensive research shows that healthy development, learning, and positive mental health during our adolescent years all require healthy, restful sleep. Schools, employers, youth-serving programs, and youth-focused residential settings should prioritize providing young people with schedules and conditions that promote quality sleep.
