This training will address the rewards and challenges of parenting young people who are ages 18 to 29. This will include a description of recent societal changes that have extended the space between adolescence and full adulthood, creating a new life stage of “emerging adulthood” in between. Problems and mental health issues common to ages 18 to 29 will also be identified and discussed. Relations with parents during this new life stage will be highlighted, including the rewards and the challenges. The first part of the training will inform participants about normal development from ages 18 to 29, including how what is “normal” has changed over the past half century, as education has become broader and longer and as ages of entering marriage and parenthood have come later. Historical developments over the past 70 years leading to the rise of the new life stage of emerging adulthood will be outlined.Problems and mental health challenges will also be discussed, including depression, anxiety, and substance abuse, in the context of normative developmental challenges such as identity explorations. These portions will lay the foundation for the main focus of the webinar, on relations between parents and children during the years from age 18 to 29. Many aspects of their relationships will be addressed, but the focus will be on understanding how parents’ authority over their children’s lives diminishes during these years. There will be an informed discussion of the questions: “How can you know when to speak up and when to refrain from intervening during these years?” “How can parents judge the level of contact and involvement that is best for their children during emerging adulthood?”
