Final answer:
An effective counselor in the person-centered approach must exhibit unconditional positive regard, genuineness, and empathy, creating a supportive environment for client growth.
Step-by-step explanation:
In the person-centered approach to counseling, developed by Carl Rogers, an effective counselor must possess several key qualities to maximize the therapy's effectiveness. These qualities include unconditional positive regard, genuineness, and empathy. Unconditional positive regard means that the therapist accepts and values the client for who they are, without judgement. Genuineness refers to the therapist being authentic and transparent with their feelings. Empathy is the ability to understand and share the feelings of the client. By embodying these characteristics, a counselor can create a supportive and safe environment that empowers clients to explore their feelings and facilitate their own growth.
