Abstract
As adolescents enter and exit high school, they face numerous changes that reflect the process of transitioning from childhood to adulthood. Concerns written by 216 adolescents who were part of a larger longitudinal study were analyzed for manifest content. Twenty-one categories of concerns were identified. The categories endorsed most frequently were education, relationships, expectations, and the future. Three of these differed significantly between the participant's first and fourth years in high school. These concerns reflect both developmental and situational transitions congruent with transition theory and have implications for nursing practice, research, and further theory development.
