History of psychotherapy
In an informal sense, psychotherapy can be said to have been practiced through the ages, as individuals received psychological counsel and reassurance from others.
According to Colin Feltham, “The Stoics were one of the main Hellenistic schools of philosophy and therapy, along with the Sceptics and Epicureans (Nussbaum, 1994). Philosophers and physicians from these schools practised psychotherapy among the Greeks and Romans from about the late 4th century BC to the 4th century AD.”
Psychoanalysis was perhaps the first specific school of psychotherapy, developed by Sigmund Freud and others through the early 20th century. Trained as a neurologist, Freud began focusing on problems that appeared to have no discernible organic basis, and theorized that they had psychological causes originating in childhood experiences and the unconscious mind. Techniques such as dream interpretation, free association, transference and analysis of the id, ego and superego were developed.
Starting in the 1950s Carl Rogers brought Person-centered psychotherapy into mainstream focus.
Many theorists, including Anna Freud, Alfred Adler, Carl Jung, Karen Horney, Otto Rank, Erik Erikson, Melanie Klein, and Heinz Kohut, built upon Freud’s fundamental ideas and often formed their own differentiating systems of psychotherapy. These were all later categorized as psychodynamic, meaning anything that involved the psyche’s conscious/unconscious influence on external relationships and the self. Sessions tended to number into the hundreds over several years.
Behaviorism developed in the 1920s, and behavior modification as a therapy became popularized in the 1950s and 1960s. Notable contributors were Joseph Wolpe in South Africa, M.B. Shipiro and Hans Eysenck in Britain, and John B. Watson and B.F. Skinner in the United States. Behavioral therapy approaches relied on principles of operant conditioning, classical conditioning and social learning theory to bring about therapeutic change in observable symptoms. The approach became commonly used for phobias, as well as other disorders.
Some therapeutic approaches developed out of the European school of existential philosophy. Concerned mainly with the individual’s ability to develop and preserve a sense of meaning and purpose throughout life, major contributors to the field in the US (e.g., Irvin Yalom, Rollo May) and Europe (Viktor Frankl, Ludwig Binswanger, Medard Boss, R.D.Laing, Emmy van Deurzen) and later in the 1960s and 1970s both in the United Kingdom and in Canada, Eugene Heimler  attempted to create therapies sensitive to common ‘life crises’ springing from the essential bleakness of human self-awareness, previously accessible only through the complex writings of existential philosophers (e.g., Søren Kierkegaard, Jean-Paul Sartre, Gabriel Marcel, Martin Heidegger, Friedrich Nietzsche). The uniqueness of the patient-therapist relationship thus also forms a vehicle for therapeutic enquiry. A related body of thought in psychotherapy started in the 1950s with Carl Rogers. Based on existentialism and the works of Abraham Maslow and his hierarchy of human needs, Rogers brought person-centered psychotherapy into mainstream focus. The primary requirement of Rogers is that the client should be in receipt of three core ‘conditions’ from their counsellor or therapist: unconditional positive regard, also sometimes described as ‘prizing’ the person or valuing the humanity of an individual, congruence [authenticity/genuineness/transparency], and empathic understanding. The aim in using the ‘core conditions’ is to facilitate therapeutic change within a non-directive relationship conducive to enhancing the client’s psychological well being. This type of interaction enables the client to fully experience and express themselves. Others developed the approach, like Fritz and Laura Perls in the creation of Gestalt therapy, as well as Marshall Rosenberg, founder of Nonviolent Communication, and Eric Berne, founder of Transactional Analysis. Later these fields of psychotherapy would become what is known as humanistic psychotherapy today. Self-help groups and books became widespread.
During the 1950s, Albert Ellis originated Rational Emotive Behavior Therapy (REBT). A few years later, psychiatrist Aaron T. Beck developed a form of psychotherapy known as cognitive therapy. Both of these included generally relative short, structured and present-focused therapy aimed at identifying and changing a person’s beliefs, appraisals and reaction-patterns, by contrast with the more long-lasting insight-based approach of psycho-dynamic or humanistic therapies. Cognitive and behavioral therapy approaches were combined and grouped under the heading and umbrella-term Cognitive behavioral therapy (CBT) in the 1970s. Many approaches within CBT were oriented towards active/directive collaborative empiricism and mapping, assessing and modifying clients core beliefs and dysfunctional schemas. These approaches gained widespread acceptance as a primary treatment for numerous disorders. A “third wave” of cognitive and behavioral therapies developed, including Acceptance and Commitment Therapy and Dialectical behavior therapy, which expanded the concepts to other disorders and/or added novel components and mindfulness exercises. Counseling methods developed, including solution-focused therapy and systemic coaching. During the 1960s and 1970s Eugene Heimler, after training in the new discipline of psychiatric social work, developed Heimler method of Human Social Functioning, a methodology based on the principle that frustration is the potential to human flourishing.
Postmodern psychotherapies such as Narrative Therapy and Coherence Therapy did not impose definitions of mental health and illness, but rather saw the goal of therapy as something constructed by the client and therapist in a social context. Systems Therapy also developed, which focuses on family and group dynamics—and Transpersonal psychology, which focuses on the spiritual facet of human experience. Other important orientations developed in the last three decades include Feminist therapy, Brief therapy, Somatic Psychology, Expressive therapy, applied Positive psychology and the Human Givens approach which is building on the best of what has gone before. A survey of over 2,500 US therapists in 2006 revealed the most utilized models of therapy and the ten most influential therapists of the previous quarter-century.
