Self-Esteem, Extraversion, Neuroticism and Health As Predictors of Quality of Life

The study verified self-esteem, extraversion, neuroticism and health as predictors of subjectively-assessed quality of life. The sample included 109 adolescents (69 healthy adolescents and 40 adolescents with upper respiratory tract disease). The research tools used were WHOQOL-BREF (WHO, 1998), Rosenberg´s self-esteem scale (Rosenberg, 1965) and NEO-FFI personality questionnaire (Hřebíčková et al., 2002). The results were processed using the multiple linear regression analysis stepwise method. Health was not found to be a predictor of subjectively-assessed quality of life in the research sample. Self-esteem was found to be a predictor of psychological (48% of variance) and environmental (25% of variance) quality of life. Neuroticism was confirmed as a predictor only for physical quality of life (8% of variance). Extraversion was established as a universal predictor for all the aspects of quality of life measured: physical (20% of variance), psychological (8% of variance) and environmental (10% of variance).
