[Assessment of grief exemplified pregnancy loss: development and initial results on the validity of the Munich Grief Scale]. 
Bereavement research is hampered conceptually by confounding of grief and depression, methodologically by a lack of generally agreed-upon measures.  Therefore we developed the Munich Grief Scale (MGS) based on the Perinatal Grief Scale (PGS, Potvin et al.  1989) and results from a previous study.  Validation included comparisons with standardized self-report scales of depression, anxiety and physical symptoms.  It was based on a follow-up study of 125 patients who had miscarried and 3 comparison groups who either suffered from a miscarriage or a stillbirth.  Self-reports were compared to expert ratings of grief and depression.  The MGS is a economical, reliable self- and expert rating scale after pregnancy loss.  The applicability of the grief measures to other kinds of bereavements remains to be determined.
