Step-by-step explanation:
The three factors that comprise a person-centered approach in therapy, as developed by Carl Rogers, are unconditional positive regard, genuineness, and empathy. Rogers emphasized that these core conditions are essential for a therapeutic environment that facilitates personal growth and self-actualization.
Unconditional positive regard involves accepting and respecting the client without judgment, genuineness requires the therapist to be open and authentic in the therapeutic relationship, and empathy is the ability of the therapist to deeply understand the client's experience from their perspective.
