The authors screened 105 applicants for attendance at a week-long T-group conducted by nonprofessionals. The psychological evaluation and screening procedures included a written application, psychological tests, and a small group experience. Fifteen applicants were not permitted to attend the T-group; six additional applicants chose not to attend. The authors describe the diagnostic groupings of those who were rejected and present vignettes of several applicants. They also discuss the need for screening procedures for any group experience and the current lack of established guidelines for such screening.
