group therapy a form of psychotherapy in which a group of patients meets regularly with a group leader, usually a therapist. The group may be balanced, having patients with diverse problems and attitudes, or it may be composed of patients who all have similar diagnoses or issues to resolve. In some groups, patients may be basically mentally healthy but trying to work through external stressors, such as job loss, natural disasters, or physical illness. Self-help groups are groups of people with a commonality of diagnosis (e.g., alcoholism, overeating, or a particular chronic physical illness) or of experience (e.g., rape, incest) and a leader who may be not a therapist but rather one who has experienced a similar problem or situation.

From hearing how the group leader or other members feel about this behavior, the patient may gain insight into his or her anxieties and conflicts. The group may provide emotional support for self-revelation and a structured environment for trying out new ways of relating to people. In contrast, there are other groups that focus on altering behavior, with less or minimal attention paid to gaining insight into the causes of the problems.
therapy group in the nursing interventions classification, a nursing intervention defined as the application of psychotherapeutic techniques to a group, including the utilization of interactions between members of the group. See also group therapy.
training group sensitivity group.
