Psychotherapy, or personal counseling having a psychotherapist, is an intentional social relationship used by trained psychotherapists to aid a client or individual in problems of living. It aims to increase the individual's sense of their own well-being. Psychotherapists employ a variety of techniques based on experiential connection actions, communication, dialogue and building change and that are designed to improve the mental health of a client or patient, or to enhance group relationships (such as within a family). Psychotherapy may also be done by practitioners with a number of different credentials, including psychiatry, clinical mindset, clinical social work, guidance psychology, mental health guidance, clinical or psychiatric sociable work, marriage and loved ones therapy, rehabilitation counseling, songs therapy, occupational therapy, psychiatric nursing, other individuals and psychoanalysis. It may be legitimately regulated, voluntarily regulated or unregulated, depending on the jurisdiction. Often require graduate university and supervised clinical experience, though requirements of these careers vary. Most forms of psychotherapy use spoken conversation. Some also use various other forms of conversation such as the written word, drama and artwork narrative story or music. Psychotherapy with children and their parents often involves play, dramatization (i.e. role-play), and drawing, with a co-constructed narrative from these low-verbal and displaced modes of interacting. Psychotherapy occurs within a structured experience between a trained therapist and client(s). Purposeful, theoretically based psychotherapy began in the 19th century with psychoanalysis; since then, scores of other approaches have been developed and continue to be created. Therapy is generally used in response to a number of specific or non-specific manifestations of medically diagnosable and/or existential crises. Treatment of everyday problems is more often referred to as counseling (a distinction originally adopted by Carl Rogers). However, the term guidance is sometimes used interchangeably with "psychotherapy". While some psychotherapeutic interventions are designed to treat the patient making use of the medical model, many psychotherapeutic approaches do not adhere to the symptom-based model of "illness/cure". Some practitioners, such as humanistic therapists, see themselves a lot more in a facilitative/helper role. Therapists are anticipated, and usually legally bound, to respect client or patient confidentiality, as sensitive and deeply personal topics are frequently discussed during psychotherapy. The critical importance of confidentiality is enshrined in the regulatory psychotherapeutic organizations' codes of moral practice.
