The study concerns the connection between the feeling of autonomy implied as self-determination and family relationships among 17-to-19-year-old adolescents. The study was inspired by Bowlby’s theory of attachment and Ryan and Deci’s theory of self-determination. The subjects were 145 adolescent high-school students (82 female and 61 male). The Inventory of Parent and Peer Attachment, Family of Origin Scale and Self-Determination Scale were used in this study. The results led to a conclusion that healthy family relationships and a secure pattern of attachment correspond to a higher autonomy seen as self-determination. The Self-Determination Scale that was used reached a high reliability index, which suggests that it might be a useful tool for future studies and that it might be worth conducting its cultural adaptation.
