Final answer:
Andrea's behavior is indicative of role confusion, a challenge during the adolescent stage of psychosocial development, characterized by a lack of stable identity and disregard for parental disapproval.
Step-by-step explanation:
The behavior exhibited by sixteen-year-old Andrea can indeed be indicative of role confusion, where she is unsure of her identity and confused about her future. In the context of Erik Erikson's stages of psychosocial development, particularly during adolescence which spans from ages 12 to 18, the primary task is the development of a sense of self. Andrea's disengagement from school and employment, coupled with her withdrawal into online chat rooms, suggests a struggle in establishing a stable identity. This behavior, and her disregard for her parent's disapproval, reflect role confusion which occurs when an adolescent cannot establish a personal sense of identity and direction. Adolescents in this state tend to exhibit apathy towards their future or a lack of adherence to any specific role, often leading to a segmented sense of self.
