The participants were 102 students (71 men (86.9 %) and 31 women (30.1 %) between 14 to 19 years of age (\pmb{M}=\mathbf{16.93},\ \pmb{SD} =\pmb{.89}). One concludes that to exhibit the personal life in social networks on the part of the adolescents predicts in a positive form the publications in social networks of the parents, also he predicts the self-esteem and the satisfaction with the life. Furthermore, the self-esteem predicts the life satisfaction. Finally, the mediation model confirmed of significant form with the Test of Sobel (\mathbf{Test\ Statistic} =\mathbf{1.97},\ \pmb{SE}=\mathbf{.06},\ \pmb{p} < \mathbf{.05}) that the exhibition in social networks on behalf of the adolescents (variable independent) predicts the life satisfaction (dependent variable) when mediated by self-esteem (mediating variable).
