Final answer:
The type of parenting that helps adolescents develop a healthy self-concept is authoritative parenting.
Step-by-step explanation:
The type of parenting that helps adolescents develop a healthy self-concept is authoritative parenting. In the authoritative style, parents provide reasonable demands and consistent limits, express warmth and affection, and listen to the child's point of view. They also set rules and explain the reasons behind them, while remaining flexible and open to exceptions. This style encourages high self-esteem and social skills in adolescents. On the other hand, authoritarian parenting, which emphasizes strictness and obedience, can lead to anxious and unhappy kids. The permissive parenting style, where parents have few demands and rarely use punishment, can result in a lack of self-discipline and negatively impact grades. It's important to note that the effectiveness of parenting styles varies across different cultures.
