The young adult period is characterised by rapid physiological, sexual, cognitive and emotional changes. The transition from adolescent to adult becomes apparent as one completes the process of physical maturation and secondary sexual characteristics become fully formed. Many young adults experience a change in or challenges to their world views. As young adults enter new academic settings, new social circles, or new workplace environments, beliefs and values held throughout childhood may be questioned by others from different backgrounds or challenged by new ideas.

Young adults may often find the support of a counsellor to be helpful during the transition from adolescence into adulthood, especially if they experience mental health concerns or other difficulties as they become accustomed to new expectations, roles and responsibilities. Some common issues that young adults are often vulnerable to include substance abuse, eating disorders, depression and anxiety. When young adults seek help for mental health concerns, they can benefit from a range of interventions and counselling modalities. Among these are cognitive behaviour therapy and interpersonal therapy, both of which are counselling approaches that can help young adults identify and alter negative thought patterns and feelings and work towards personal goals.
