The purpose of this study is to examine subjective well-being with respect to problem solving, self-esteem in decision-making and decision-making styles in adolescents. For this purpose, "Positive and Negative Affect Scale", "Satisfaction with Life Scale", "Adolescent Decision Making Scale" and "Problem Solving Inventory" were administered to 377 adolescents (52.8% females; M = 15.72; SD = 1.21). The data were analyzed through stepwise regression analysis. The results of the analysis showed that "problem solving" and "self-esteem in decision making" significantly predict subjective well-being and its dimensions. The results also revealed that "vigilance style" is a significant predictor of subjective well-being and positive affect while "panic style" is a significant predictor of negative affect. In contrast, "cop-out style" in decision making is found be a non-significant predictor of subjective well-being and its dimensions. The most important predictors of life satisfaction have been respectively found to be "problem solving" and "self-esteem in decision making''. Results also showed that "problem solving", "panic style" and "self-esteem in decision making'' are predictors of negative affect. The results are discussed in relation to previous research; study limitations and further research directions are also outlined.
