According to the theoretical model of emotional styles derived from neuroscientific studies, there are six dimensions of emotional life: Outlook, Resilience, Social intuition, Selfawareness, Sensitivity to context and Attention while the integrative measure of emotional functioning is Healthy emotionality. The aim of this research was to examine gender differences in the emotional styles of adolescents as well as the relations between emotional styles of parents and adolescents and indicators of subjective well-being of adolescents. Likewise, the goal was to examine the contributions of adolescents' emotional styles to indicators of their subjective well-being, while controlling for gender and age. Mediation effects of emotional styles of adolescents in relation to the same emotional styles of parents and indicators of subjective well-being of adolescents were also examined. A total of 269 highschool and elementary school pupils aged 14 to 19 and 63 parents aged 35 to 60 participated in this research. Each parent was paired with their child. When examining a sample of adolescents, Emotional Style Questionnaire (ESQ), Positive and Negative Affect Schedule (PANAS), The Social and Emotional Loneliness Scale (SELSA) and the Life Satisfaction Scale were applied, while just the Emotional Style Questionnare was applied to parents. The results of the research show girls score lower on the dimensions of emotional styles compared to boys. Also, research showed significant correlations between almost all emotional styles of parents and Healthy emotionality of adolescents, as well as the correlations between parental and adolescent's Attention and parental and adolescent's Healthy emotionality. Most indicators of subjective well-being of adolescents were found to be significantly correlated to all adolescent's emotional styles as well as to most parental emotional styles. Emotional styles of adolescents contributed to all indicators of subjective well-being. A statistically significant mediation effect was obtained only for adolescent's Healthy emotionality in the relation between parental Healthy emotionality and adolescent's Positive affect, which is in line with expectations and literature. The results of this research provide implications for working on relationships between parents and adolescent children, educating parents on healthy emotional functioning and working with adolescent girls on the issue of emotional functioning.
