What is the key feature of identity crises?

The defining characteristic of identity crises involves confusion regarding an individual's sense of self and their personal values. During an identity crisis, a person may grapple with questions about who they are, what they believe, and how they fit within the broader context of society. This confusion can lead to feelings of uncertainty and instability as individuals explore different aspects of their identity, which can vary by age and life stage, notably during adolescence and emerging adulthood.

The other options present situations that do not align with the nature of an identity crisis. Clarity in personal beliefs and values suggests a strong sense of self rather than confusion, making it contrary to the very essence of what an identity crisis entails. Unwavering confidence in societal roles signifies a firm understanding and acceptance of one's place in society, which also does not reflect the feelings of doubt and exploration typical of an identity crisis. Lastly, reliance on others' opinions for self-understanding can indicate a lack of self-confidence or autonomy but does not directly capture the broader struggle with self-identity and values characteristic of an identity crisis.
