Which behavior indicates that a client is becoming more assertive?

The behavior indicating that a client is becoming more assertive is when the client asks his roommate to tidy up after himself. This action demonstrates assertiveness because it involves expressing a need or request directly and confidently without aggression or passivity. It shows that the client is willing to communicate their feelings and expectations to others, which is a key component of assertive behavior.

Assertiveness is about advocating for oneself and addressing situations that may be problematic rather than avoiding conflict or relying on others to address problems. In this case, the client is taking the initiative to set boundaries and ask for what he wants, reflecting a positive step toward healthy interpersonal interactions.
