The client-centered therapy developed by Carl Rogers is based on:

The correct option is Humanistic approach.

Carl Rogers was a pioneer of humanistic psychology, a school of thought that emerged in the mid-20th century as a reaction to both psychoanalysis (the psychodynamic approach) and behaviorism (the behavioral approach). Humanistic psychology emphasizes the study of the whole person, focusing on individual potential, free will, self-actualization, and the belief that people are inherently good and motivated to grow.

Client-centered therapy (also known as person-centered therapy) directly reflects Rogers' humanistic philosophy. In this therapeutic framework, the client is viewed as the expert in their own life. Rather than directing the client or analyzing their unconscious mind, the therapist provides a supportive environment characterized by three core conditions:
1. Empathy: Sensing the client's private world as if it were one's own.
2. Unconditional Positive Regard (UPR): Accepting and valuing the client without judgment or conditions.
3. Congruence (Genuineness): The therapist being real, authentic, and transparent in the relationship.

By experiencing these humanistic conditions, clients are empowered to explore their feelings safely, resolve incongruence between their real self and ideal self, and move toward self-actualization.
