Adolescent quality of life, part I: conceptual and measurement model.

Few quality of life instruments exist that focus on the positive aspects of adolescence, incorporate adolescents' perspectives and language, and apply to both general and vulnerable populations. With these goals in mind, a conceptual and measurement model was developed using inductive qualitative methods to guide construction of the Youth Quality of Life Instrument-Research Version (YQOL-R). A conceptual model with four domains-Sense of Self, Social Relationships, Environment, and General Quality of Life-is reported.
