The therapist and client in Person-Centered Therapy have a very open relationship. Their direction and goals are not well defined but not in a free for all way. The therapist will actively engage all areas that could be troublesome to the client whether it be the past, present, or future. The therapist will also do a lot of reflecting during sessions and observe the client deeply. The therapist must be very patient.
Therapists who practice Person-Center Therapy do not make use of the DSM simply because the therapy does not match every diagnosis. This approach is more philosophical and reflective. Also, typical psychological tests are rarely used due to the fact that the approach is more about thinking deeply about past decisions and reflecting on the outcomes.
