Nowadays, the terms “therapy”, “counseling”, and “psychotherapy” are used interchangeably. The difference is more a matter of tradition and regional culture than of actual practice.
Historically, “therapists” and “psychotherapists” treated mental health problems, while “counselors” focused on career and personal development. Today, the field of mental health has grown enough, and has accumulated enough scientific evidence, to establish that people benefit from a combination of both healing and personal development. Professionalization and research evidence in the helping field have led to the unification of tools and principles across professions.
As long as the helper is licensed, whether as counselor or therapist, e.g. psychologist, mental health counselor, social worker, or family therapist, he/she will use unified shared principles, scientific knowledge, theories, techniques, and clinical methods.
