Clinical overview

Born in Bucharest and educated in Vienna, Jacob Levy Moreno worked with children, marginalised communities and refugees. In Vienna in the early 1920s he experimented with improvisational theatre, which later contributed to his development of psychodrama.

After moving to the United States in 1925, Moreno developed psychodrama and sociometry, including ways to map relationships within groups. His work influenced later action-oriented approaches; an individual historical account does not establish that enactment is more effective than talking therapy.

Historical and clinical context

Moreno drew on theatre, improvisation and the idea of encounter in developing his approach. Psychodrama can involve exploring a situation through action with a director and other participants.

In psychodrama, the client ('protagonist') is invited to stop talking 'about' a painful memory, feared future encounter, or internal conflict and instead step onto the stage to enact it directly ('Don't tell me, show me'). Assisted by the therapist ('director'), group members playing key figures ('auxiliary egos'), and the witnessing group, the protagonist explores unvoiced feelings, tries new responses ('surplus reality'), and steps directly into the other person's shoes through role reversal.

Core therapeutic contributions

Psychodrama and Action Methods. Developed psychodrama using warm-up, enactment and group sharing, with techniques such as role reversal, doubling and the mirror.

Group Psychotherapy and 'Tele' (1932). Helped develop group psychotherapy and described tele as a way to consider relationships and reciprocal feelings between people.

Sociometry and Social Network Analysis (1934). Developed sociometry and used sociograms to represent patterns of choice and relationships within groups, contributing to later research on social networks.

In the consulting room

Therapeutic stance. Moreno described an active group approach using dramatic enactment and attention to relationships.

Signature practices. Role reversal: inviting the client to step physically into the chair or posture of the significant other (or an internal part) and speak in the first person; Doubling: another participant offers words for an experience the protagonist may accept, change or reject; The Empty Chair and 'Surplus Reality': staging conversations with absent, deceased, or internal figures that could never occur in ordinary life; Closing enactments with 'sharing' (group members speaking from their own resonant vulnerability) rather than superior diagnostic 'analysis' of the protagonist

Common misreadings. Assuming that dramatic enactment is necessarily more effective than talking about an experience; Treating psychodrama as a single technique or assuming that every group uses the same methods

Landmark clinical works

1914, Einladung zu einer Begegnung (Invitation to an Encounter) (book). Early poetic manifesto formulating the 'Encounter' (Begegnung) and radical role reversal ('I will look at you with your eyes, and you will look at me with mine'), predating Martin Buber's I and Thou.

1924, Das Stegreiftheater (The Theatre of Spontaneity) (book). Documented the transition from improvisational theatre in Vienna to therapeutic enactment.

1934, Who Shall Survive? A New Approach to the Problem of Human Interrelations (book). Monumental work introducing sociometry, sociograms, role theory, and the concept of 'tele'.

1946, Psychodrama, Volume 1 (book). Definitive clinical manual of psychodrama theory, stage architecture, and core action techniques.

1959, Psychodrama, Volume 2: Foundations of Psychotherapy (with Zerka T. Moreno) (book). Co-authored with Zerka Toeman Moreno, refining psychodramatic ethics, group process, and clinical supervision.

Clinical critiques and limitations

Psychodrama involves a range of methods and settings. A 2025 systematic review of studies published from 2018 to 2022 found methodological limitations, including small samples, relatively few randomised trials and limited follow-up. It does not establish that enactment is superior to verbal treatment.

Group enactment should be considered in relation to the person, setting and consent; a historical account does not establish that a particular method is appropriate for everyone.
