In adolescence, the way you look and how you think others see you are central to developing identity. Chemotherapy often brings visible changes—hair loss, skin changes, weight shifts, fatigue—that can make a teen feel different from their peers. That sense of altering appearance and not fitting in can cause the most distress and influence daily life more than other issues. Missing time at school or limiting social activities are real concerns, but they are often secondary to the impact of body changes on self-image and peer acceptance. Feeling dependent or adopting a “sick role” can feel uncomfortable for teens who want independence, yet the deepest worry tends to be how these health problems alter their body image and sense of normalcy.

Postconventional reasoning in Kohlberg's theory centers on evaluating laws and rules in light of universal ethical principles and the idea that laws are social contracts that can be changed to promote justice. At this level, people may follow laws when they serve fairness and rights, but they also recognize that laws should be modified or challenged if they no longer protect people or advance the greater good. The statement described—following societal laws while acknowledging they can be changed to improve society—embodies this social-contract orientation, showing a flexible, principled approach to morality rather than blind obedience. In contrast, following rules due to fear of punishment reflects earlier, preconventional thinking; seeking approval of an immediate group shows conventional thinking focused on interpersonal accord; and believing there is only one correct view suggests a rigid, absolutist stance not aligned with postconventional reasoning.

Self-consciousness in adolescence is explained by the formal operational stage. This period, beginning around puberty, brings the ability to think abstractly and hypothetically, and to reflect on one’s own thoughts (metacognition). With these skills, teens can consider possibilities, reason about abstract concepts, and think about how others view them, which fuels self-awareness and concerns about identity. Earlier stages lack this level of abstract, self-reflective reasoning, so they don’t account for the introspective changes seen during adolescence.

In Kohlberg's framework, the stage that centers on maintaining social order is the one where moral reasoning focuses on upholding laws, authorities, and duties to the community. Here, a person believes that rules exist to keep society functioning and that individuals have an obligation to follow them and to perform their civic duties. They assess actions by how well they support the functioning of society and respect for authorities, rather than by personal gain or approval from peers. This contrasts with earlier stages, which are driven by obedience to avoid punishment or by personal gain, and with later stages that consider abstract principles or social contracts. So, when the question points to concerns about society, it corresponds to upholding laws and social order.
