Teenagers might not outgrow behavioral problems according to recent research published int the British Medical Journal. Researchers followed 3,500 teens for 40 years to assess the degree to which adolescent behavioral problems persist into adulthood. Even those with relatively mild issues had poor outcomes in adulthood. Teenage behavioral problems are critical indicators of a person who has difficulties developing and maintaining positive relationships which can impact their long-term mental health, employment stability, and family life. It just might not be a phase. Many people assume a teen will outgrow it but without intervention these adolescent behaviors could develop into serious long-term problems.
