Changes in a teen's physical and cognitive development come with big changes in their relationships with family and friends. Family relationships are often reorganized during puberty. Teens want more independence and more emotional distance between them and their parents. A teen's focus often shifts to social interactions and friendships. This includes same-sex friends, same-sex groups of friends, and boy/girl groups of friends. Sexual maturity triggers interest in dating and sexual relationships.
Changes in relationship with self
During the teens, a new understanding of one's self occurs. This may include changes in these self-concepts:
Independence. This means making decisions for one's self and acting on one's own thought processes and judgment. Teens start to learn to work out problems on their own. With more reasoning and intuitive abilities, teens start to face new responsibilities and to enjoy their own thoughts and actions. Teens start to have thoughts and fantasies about their future and adult life (for example, college or job training, work, and marriage).
Identity. This is defined as a sense of self or one's personality. One of the key tasks of adolescence is to reach a sense of a personal identity and a secure sense of self. A teen gets comfortable with, and accepts a more mature physical body. They also learn to use their own judgment, and make decisions on their own. As these things happen, the teen addresses his or her own problems and starts to develop a concept of himself or herself. Trouble developing a clear concept of self or identity occurs when a teen can’t resolve struggles about who he or she is as a physical, sexual, and independent person.
Self-esteem. This is the feeling one has about one's self. Self-esteem is determined by answering the question "How much do I like myself?" With the start of adolescence, a decrease in self-esteem is somewhat common. This is due to the many body changes, new thoughts, and new ways of thinking about things. Teens are more thoughtful about who they are and who they want to be. They notice differences in the way they act and the way they think they should act. Once teens start thinking about their actions and characteristics, they are faced with how they judge themselves. Many teens place importance on attractiveness. When teens don’t think they are attractive, it often causes poor self-esteem. Typically, self-esteem increases once teens develop a better sense of who they are.
Changes in peer relationships
Teens spend more time with friends. They report feeling more understood and accepted by their friends. Less and less time is spent with parents and other family members.
Close friendships tend to develop between teens with similar interests, social class, and ethnic backgrounds. While childhood friendships tend to be based on common activities, teen friendships expand to include similarities in attitudes, values, and shared activities. Teen friendships also tend to be based on educational interests. Especially for girls, close, intimate, self-disclosing conversations with friends help to explore identities and define one's sense of self. Conversations within these important friendships also help teens explore their sexuality and how they feel about it. The friendships of teen boys tend to be less intimate than those of girls. Boys are more prone to form an alliance with a group of friends who confirm each other's worth through actions and deeds rather than personal sharing.
Changes in male-female relationships
The shift to male-female and sexual relationships is influenced by sexual interest and by social and cultural influences and expectations. Social and cultural expectations and behaviors in male-female or sexual relationships are learned from observations and practice. During adolescence, developmental tasks include struggles to gain control over sexual and aggressive urges. And by discovering potential or actual love relationships. Sexual behaviors during adolescence may include impulsive behavior, a wide range of experimental interactions of mutual exploring, and eventually intercourse. Biological differences, and differences in the ways males and females socialize, set the stage for males and females to have different expectations of sexual and love relationships. These may influence sexual experiences and may also have consequences for later sexual behavior and partnerships. In time, having a mutually satisfying sexual partnership within a love relationship may be found.
Changes in family relationships
One of the developmental tasks of adolescence is to separate from one's family as one emerges into an independent young adult. A part of this process is coming to terms with specific feelings about one's family. During adolescence, teens start to realize that their parents and significant authority figures don’t know everything or have solutions to all types of struggles. Some teenage rebellion against parents is common and normal. With the start of puberty, girls tend to have more disagreements with their mothers. Boys, especially those who mature early, also tend to have more disagreements with their mothers than with their fathers. While over time disagreements often decrease, relationships with mothers tend to change more than relationships with fathers. As adolescents become more independent from their parents, they are more likely to turn to their peers for advice.
