We conducted this study on 52 adolescents from Tehran to investigate their perspectives on health. We used the grounded theory approach and the constant comparison analysis method. Identity emerged as a core variable along with the concepts of friendship and relationships, education, family, lack of limitation and community. Identity affects adolescents’ health regarding the emerged concepts. Participants believed that psychosocial health-related factors were more important than physical and individual health factors. Therefore, social welfare, healthy family/friendship, and caring for adolescents’ individuality are important for healthy adolescence.
