Step 1: Identify the approach.
Non-directive therapy, developed by Carl Rogers, is also known as client-centered/person-centered therapy. The therapist offers empathy, unconditional positive regard, and congruence, facilitating self-actualization rather than directing solutions.
Step 2: Differentiate from distractors.
Gestalt therapy (Perls) emphasizes awareness and here-and-now experiments; behaviour therapy uses conditioning-based techniques—both are more directive.
Step 3: Conclude.
