What this research studies

You would be part of a group that researchers have followed since age 8 in nine countries, and they continue to check in as you move through early adulthood. The team conducts annual interviews with young adults and their parents about family relationships, attitudes, mental health, substance use, decision-making, and cultural values. They compare information collected over many years to see which childhood and adolescent experiences, and which COVID-related changes, link to better or worse adjustment in the early twenties. The study uses standardized questionnaires and repeated interviews to spot patterns that are similar or different across cultures.

Who could benefit from this research

Good fit: Ideal participants are young adults about 22–26 years old who grew up in the participating countries and were part of the original Parenting Across Cultures cohort or similar individuals invited by the research team.

Not a fit: People who are not part of the international cohort or who are much younger or older than the target age range are unlikely to participate or directly benefit from this specific study.

Why it matters

Potential benefit: If successful, the findings could help families, clinicians, and policymakers design better supports to reduce mental health, substance use, and injury risks for young adults.

How similar studies have performed: Previous long-term studies have linked childhood and adolescent experiences to adult outcomes, but this multinational longitudinal design is relatively unique and provides broader cross-cultural insight.
