According to Carl Rogers, which condition is NOT necessary for personality change to occur?

The condition that is not necessary for personality change to occur, according to Carl Rogers, is that the therapist must give advice. Rogers emphasized the importance of a therapeutic environment characterized by empathy, unconditional positive regard, and genuineness. Rather than directing the therapy session or providing specific advice, the therapist's role is to facilitate self-exploration and self-acceptance in the client.

This facilitative approach allows clients to find their own solutions and move towards personal growth, making the therapist's advice unnecessary for effective therapy. The other conditions—therapist empathy, client incongruence, and the therapeutic relationship itself—are foundational to Rogers' person-centered therapy, as they create a supportive space where clients can explore their thoughts and feelings openly.
