At the beginning of the 1990s a group of psychologists and psychiatrist, affiliated with the field of transpersonal psychology, saw the need for a new psychiatric category involving religious and spiritual problems. Their concern was the possibility of misdiagnosis of these problems. Based on an extensive literature review, and networking with the American Psychiatric Association "Committee on Religion and Psychiatry", the group made a proposal for a new diagnostic category entitled "Psychoreligious or Psychospiritual Problem". The proposal was submitted to the Task Force on DSM-IV in 1991. The category was approved by the Task Force in 1993, after changing the title to "Religious or Spiritual Problem". It is included in the fourth edition of the "Diagnostic and Statistical Manual of Mental Disorders" (DSM-IV), as a minor category.
