Large-group awareness training

The term large-group awareness training (LGAT) refers to activities—usually offered by groups with links to the human potential movement—which claim to increase self-awareness and to bring about desirable transformations in individuals' personal lives. LGATs are unconventional; they often take place over several days, and may compromise participants' mental wellbeing.

LGAT programs may involve several hundred people at a time. Though early definitions cited LGATs as featuring unusually long durations, more recent texts describe trainings lasting from a few hours to a few days.

Forsyth and Corazzini cite Lieberman (1994) as suggesting "that at least 1.3 million Americans have taken part in LGAT sessions".
