Objective: This article describes the development and initial validation of the 90-item Chinese Positive Youth Development Scale (CPYDS), which contains items related to 15 aspects of positive youth development. Method: Adolescents with well adjustment ( N = 162) and poor adjustment (N = 160) responded to the CPYDS. Results: The findings showed that the CPYDS measures possess acceptable internal consistency and were able to discriminate the two groups. Although the CPYDS measures were positively related to thriving, life satisfaction, and perceived academic achievement, they were negatively related to substance abuse, delinquency, and behavioral intention to engage in problem behavior. Conclusions: The CPYDS can be used as a global measure of positive youth development in Chinese adolescents, but its dimensionality and subscales should be further examined. (Contains 4 tables.)
