The character strengths and virtues approach is a classification system to examine the characteristics of good character in terms of twenty-four strengths and six virtues. This study was designed to investigate the psychometric properties regarding the reliability and validity of the Turkish version of the VIA-Youth. A tool developed to evaluate the character strengths of youth. In addition, character strengths were examined in terms of life satisfaction, values and demographic characteristics. 1963 high school students between 14-19 years participated in this study by completing VIA-Youth and the Human Values and Life Satisfaction inventories. The results confirm the six-factor model in the theoretical framework. It has also been concluded that character strengths affect life satisfaction and values and that socio demographic features are related to strengths. The adaptation of this inventory into Turkish culture contributes to the current understanding of the universal aspects of character strengths for studies within the context of positive youth development. Besides the adaptation, the relationships between character strengths, values, demographic characteristics and life satisfaction were discussed and suggestions were made.
