What type of complex reflection involves emphasizing a portion of what the youth is saying?

The correct response focuses on the concept of "adding content" during complex reflection. This technique involves expanding upon a specific aspect of what the youth is sharing, thereby underscoring its importance in the conversation. By emphasizing a part of their statement, the juvenile justice officer not only demonstrates active listening but also helps the youth to explore their thoughts and feelings more deeply.

For instance, if a youth expresses frustration about their experiences, an officer might reflect back on that frustration, offering insights or asking further questions that delve into the root causes of their feelings. This approach can aid the youth in processing their emotions and can facilitate a more productive dialogue about their experiences.

Other methods mentioned in the options provide different functions in communication. Amplification refers to enhancing the intensity of a statement, while double-sided reflection acknowledges multiple perspectives simultaneously. Metaphors or similes might be used to create analogies that help illustrate a point, but they do not specifically focus on emphasizing a certain element of the youth's conversation. Adding content stands out as the specific technique designed for highlighting parts of what the youth is saying, enriching the discussion and encouraging further exploration.
