Shapiro (1992) observed the effects of vipassana meditation on a small group of meditators and found that while most participants experienced positive results, a small number of meditators experienced distinctly negative states.

Glueck (1984) studied 110 participants and reported that the practice of transcendental meditation (TM) appeared to release repressed subconscious impressions. A small proportion of participants reacted adversely to this experience. Heide (1983, 1984) found that 54% of anxiety prone participants demonstrated increased anxiety during mantra meditation modelled on TM. Otis (1974) observed a cohort of 62 novices who tried TM and concluded that it was not suitable for those with serious emotional problems.

A study commissioned by the German government (1980) to assess the effects of TM on youth created controversy when it reported that the majority of participants observed during the trial experienced psychological problems, worsening concentration and variety of physical complaints. Publication of the study was unsuccessfully contested by the TM organization in the German courts.
