Addition of the new category to the DSM-system was noticed by a few psychiatric publications, and the New York Times. Several commentators have also offered their viewpoints. Chinen notes that the inclusion marks "increasing professional acceptance of transpersonal issues", while Sovatsky sees the addition as an admittance of spiritually oriented narratives into mainstream clinical practice. Smart and Smart recognizes the addition of the category, and similar improvements in the fourth version, as a step forward for the cultural sensitivity of the DSM manual. Greyson, representing the field of Near-death studies, concludes that the diagnostic category of "Religious or spiritual problem" "permits differentiation of near-death experiences and similar experiences from mental disorders". In a study from 2000 Milstein and colleagues discussed the construct validity of the new DSM-IV category religious or spiritual problem (V62.89).
