Family climate in which family members are emotionally close and respect one another favors a sense of life satisfaction in adolescents. Therefore, the aim of this study was to determine to what extent perceived parental behavior and parent attachment can predict life satisfaction in adolescents. The study included 262 high school students who completed the Children’s Report of Parental Behavior Inventory, Inventory of Parent and Peer Attachment, and Satisfaction With Life Scale. There was no significant difference between girls and boys in life satisfaction. However, there were differences in their perception of parental behavior of mothers and fathers, as well as in their attachment to mothers and fathers. Adolescents perceive mothers as more accepting, oriented towards them and that they accept their individualization more than fathers. They also have greater trust and communication with their mother as opposed to father. On the other hand, mothers are perceived as more intrusive and hostile controlling than fathers, while fathers as more hostile distant and alienated than mothers. Results showed that adolescents who perceive higher trust, communication, acceptance, orientation towards them, acceptance of their individualization, and firmer fatherly discipline in parents are more satisfied with their life. Additionally, adolescents whose parents are not alienated and hostile distant from them and whose parents show low hostile control and anxiety instillation have higher life satisfaction. Hierarchical regression analysis determined that gender, parent attachment and parental behavior together account for 41% of the variance of adolescent life satisfaction. Significant predictors were mothers’ trust, fathers’ communication, acceptance and acceptance of individualization, mothers’ orientation to child, and gender.
