Trajectories of Personal Well-Being Attributes Among High School Students in Hong Kong.

How personal well-being of adolescents changes over the high school period is not entirely clear in the scientific literature. Using 15 positive youth development (PYD) attributes as indicators of well-being, the current study investigated the related developmental trajectories among a large sample of Hong Kong adolescents from Grade 7 to Grade 12. Individual growth curve modeling revealed that while variation existed across different PYD attributes, nine out of 15 positive youth development attributes declined in the early adolescence but showed a rebound or a slower rate of decline in the late adolescence. The current study serves as a pioneering attempt to chart the normative profiles of Chinese adolescents' personal well-being over time. The theoretical and practical implications of the findings are discussed.
