Assessing quality of life for adolescents in Taiwan

This study was to evaluate the psychometric properties of the Taiwanese quality of life questionnaire for adolescents and the factors affecting the quality of life of Taiwanese adolescents. The survey involved 5538 junior high school students, aged 13-15 years. An initial 90-item questionnaire was shortened to 38 items by means of principal component analyses. Quality of life assessment involved seven factors: family, residential environment, personal competence, social relationships, physical appearance, psychological well-being, and pain. The rate of missing data was low. The Cronbach α coefficient remained above the 0.75 threshold criterion for the global scale and seven subdomain scales. A lower quality of life score was evident for female adolescents in higher grades in school, those living with a single parent or other relatives, and those living in rural areas. This 38-item questionnaire should serve as a reliable tool for future studies.
