As caring parents, we all want our kids to grow into capable, confident, thriving adults. Not perfect, but grounded, resilient and ready for life. Let’s step back from everyday school-related performance for a moment and look at the research-backed character traits that we can invest in when it comes to shaping resilient young adults. 

What the Research Says

A large body of Longitudinal research following children from early life into adulthood, agree that three powerful character traits predict whether young people become overall thriving adults. And no, these traits aren’t about being the smartest, most talented, or most outgoing. They’re behavioural foundations rooted in self-control, emotional regulation and prosocial behaviour, skills every child can learn, and every parent can help strengthen.

Let’s break down what the research tells us about each:

1. Self-Control: The Most Consistent Predictor of Thriving Adults

The Dunedin Multidisciplinary Health & Development Study, one of the most famous longitudinal studies in the world, followed 1,000 children from birth to age 32.

The finding? Kids who developed strong self-control (including things like planning, managing impulses, sticking to goals) grew up to have:

• Better physical health
• Better mental well-being
• Stronger financial stability
• Lower risk of addiction
• Lower risk of getting into trouble with the law

(Moffitt et al., 2011)

And this held true even when researchers controlled for IQ and family income, showing that self-control is not dependent on these variables. Self-control isn’t a personality type. It’s a trainable skill that protects your teen for life.

Simple ways to build it:

• Set small, achievable goals for school, fitness, or money
• Encourage routines (sleep, meals, movement)
• Help them delay gratification in small daily ways 
• Model calm decision-making yourself (talk through it with them “I’m also in the mood for takeaways but we have some leftovers still in the fridge”)
• Celebrate consistency, not perfection
  

2. Emotional Regulation: The Skill Behind Resilience

Across multiple long-term studies, including the Christchurch Health & Development Study, teens who learned how to navigate and manage big feelings, stay calm under pressure, and handle setbacks without spiraling, were significantly more likely to become emotionally stable, mentally healthy adults (Fergusson, Boden & Horwood, 2013)

Emotionally regulated teens bounce back faster, make better decisions, and experience less long-term stress (which affects immunity, sleep, academic performance and social relationships).

Ways to support this trait:

• Normalise emotions (“It’s okay to feel overwhelmed right now, let’s talk it through when you are ready.”)
• Teach them about “rubber balls” and “glass balls”. Some things or situations can “bounce back” without harsh consequences and others need to be addressed with the help of an adult.
• Use problem-solving language rather than criticism (Instead of “It’s because you didn’t listen” try “How will you be doing it different next time?”)
• Teach “name it to tame it”. A powerful emotional regulation strategy, developed by Dr. Dan Siegel, that involves verbally identifying (naming) an intense feeling as you experience it, which activates the rational part of your brain (prefrontal cortex) to calm the emotional center (amygdala), thereby reducing the feeling’s intensity (taming).
• Encourage grounding tools: breathwork, walking, journaling.
• Keep home routines predictable and simple. Structure reduces emotional overload
  

3. Prosocial Behaviour: The Trait That Builds Strong, Stable Relationships

A 40-year Finnish longitudinal programme (Pulkkinen, 2017) found that children who developed prosocial behaviours which includes kindness, cooperation, responsibility, helping others had:

• Higher relationship satisfaction
• Better career stability
• Stronger mental health
• Greater life satisfaction by mid-adulthood
  

This trait wasn’t linked to personality but to practice: families who modelled empathy, responsibility and community created teens who carried those habits into adulthood.

How to grow prosocial behaviour:

• Encourage chores and contribution at home.
• Use “we” language (“In this family, we help each other”).
• Involve teens in small acts of service.
• Celebrate kindness as loudly as achievements.
• Let them experience some form of teamwork where others need to be considered.
  

How to support character development with nutrition

Skills like self-control, emotional regulation and prosocial behaviour don’t grow in isolation. They’re shaped by the body and brain your teen carries through the world.

At GenH, we support the foundations that make these traits easier to practice:

• Balanced energy & concentration → supports self-control and prevents feeling physically overwhelmed.
• Stable mood & lower stress load → strengthens emotional regulation.
• Consistent health & vitality → helps teens show up for others.

The research is clear:

Thriving adults aren’t just born with the right character traits.

They’re shaped, through repetition, support, and moments of learning that compound over years.

You’re raising a future adult.
We’re here to help you raise a thriving one.
