There is a default assumption built into much of how we think about adolescence: that it is defined by turbulence, identity crisis, and emotional volatility. That assumption shapes everything from clinical models to how parents and teachers interpret teenage behavior. But when researchers at the University of Zurich asked over a thousand young people to describe the experiences that shaped their lives most, in open-ended, unstructured language, the picture that emerged looked almost nothing like that dominant narrative. Most of what young people described was not painful. It was hopeful, ordinary, and forward-moving.
The Study That Let Young People Speak for Themselves
The University of Zurich study, published in the Journal of Child Psychology and Psychiatry, analyzed open-ended written responses from 1,442 participants surveyed at ages 15, 17, 20, and 24. Rather than presenting participants with predefined categories or checklists of stressful events, researchers allowed them to describe formative experiences in their own words. To make sense of thousands of such responses, the team used automated language processing methods, one of the first large-scale longitudinal studies in the world to apply this approach to youth narratives.
The result was a structured map of what actually registers as significant in young people's lives over time. The methodology matters here because self-directed language reveals what people choose to foreground, not what researchers assume they should remember. That distinction is the entire ballgame.
Eighty-Three Percent of Formative Events Were Positive
The headline finding is blunt and important: 83% of the events participants described as formative were positive in nature. School, training, and apprenticeships dominated, accounting for nearly half of all mentions. Friendships and romantic relationships came in second at around 12%. Personal development and mental well-being accounted for roughly 8%, while travel and time abroad registered at approximately 7%.
These are not the categories that dominate crisis-centered clinical literature. They are the categories of a life being built, not a life being survived. First author David Bürgin, a clinical developmental psychologist, put it plainly: youth is not primarily composed of crises. Many young people primarily mention positive developmental steps such as education, relationships, and personal achievements. That sentence deserves to be read slowly, because it contradicts a great deal of what institutional frameworks around adolescent mental health have been organized to address.
How Psychological Stress Reshapes the Story
This does not mean stress is irrelevant. The study found a clear and significant pattern: adolescents and young adults reporting higher symptoms of anxiety and depression described their formative experiences very differently from their peers. They mentioned stressful relationship experiences, conflicts, loss, and personal failures more frequently. They mentioned travel, educational achievements, and sports activities far less often.
This is not simply a reflection of having lived harder lives, though that may be part of it. It also reflects how psychological distress functions as a lens. When anxiety and depression are present, the mind is drawn toward threat and loss. Positive experiences do not disappear from a person's history, but they become harder to access as formative or meaningful. The architecture of memory and meaning shifts. This has direct implications for how clinicians and educators interpret what young people report about their own development.
The Developmental Shift Between Adolescence and Early Adulthood
The longitudinal design of the study revealed something that cross-sectional snapshots cannot: the content of what feels formative changes dramatically across the years of adolescence and early adulthood. In middle adolescence, school, friendships, and leisure activities were the dominant themes. By early adulthood, the weight had shifted toward education in a vocational sense, work, romantic partnerships, housing, and in some cases, having children.
Sport and going out, significant in the teenage years, faded in prominence. Independence grew. These are not surprising transitions in the abstract, but seeing them mapped longitudinally through participants' own language gives the pattern a concreteness that aggregate statistics alone do not. Development is not a static state interrupted by events. It is an ongoing reorganization of what a person considers central to their own story.
Differences Across Gender, Background, and Migration Experience
The researchers also identified differences based on gender, social background, and experiences of migration. These differences are real and should not be minimized. A young person navigating a new country, a different language, or significant economic constraint will not experience the same developmental landscape as someone with structural stability and continuity.
What the researchers found, however, is that broadly speaking the most important topics were very similar across social groups. The core categories of education, relationships, personal growth, and increasing independence appeared consistently, even as the specific texture and weight of those experiences varied. This suggests that the underlying developmental architecture is more universal than social variation alone would predict, while the lived quality of moving through that architecture is shaped heavily by circumstance.
What Support Systems Are Getting Wrong
Co-leader Lilly Shanahan drew a direct policy implication from the findings: support services should not only focus on how to cope with stress. Stable relationships, positive experiences, and opportunities to experience self-efficacy are just as important. This is a critique embedded in a research result. The dominant design logic of youth support services has been reactive, organized around identifying and mitigating harm. The study suggests that this orientation, while necessary, is insufficient.
If 83% of what young people identify as formative is positive, then interventions that only address the other 17% are operating on a partial model of development. Building in opportunities for genuine achievement, meaningful connection, and the experience of competence is not supplementary to good youth support. According to what young people themselves report, it is central to it.
What Language Processing Reveals That Surveys Cannot
The methodological contribution of this study deserves its own attention. Christina Haag, first author and now at the University of Cambridge, noted that the automated language processing approach allowed freely formulated responses to be analyzed at scale while keeping participants' perspectives visible in their own words. That balance, between the rigor needed for large-scale analysis and the fidelity required to preserve individual meaning, is genuinely difficult to achieve.
Most large longitudinal studies force participants into predefined response categories. This produces data that is easy to aggregate but that systematically filters out anything the researchers did not already think to ask about. Open-ended language processing sidesteps that limitation. It is not a perfect method, but it is a more honest one when the research question is what actually matters to people rather than how many people fit into predefined boxes.

Article Recap
A landmark longitudinal study from the University of Zurich found that adolescents and young adults most frequently identify positive everyday milestones such as education, friendships, and personal achievements as the major life events shaping their development, directly challenging crisis-centered models of youth psychology. The research also revealed that psychological stress and symptoms of anxiety and depression significantly alter how young people perceive and recall formative experiences, shifting attention away from positive growth toward loss and conflict. These findings call for a fundamental reorientation of youth support systems, one that invests as deliberately in building conditions for positive youth development as it does in managing adolescent stress and mental health challenges.
