Title: 
Factors Affecting the Grieving Process after Perinatal Loss
Version:

Reviewer's report:
I appreciate the authors undertaking this important and difficult area of research
and bringing light to the risk factors of complicated grief (CG) associated with
perinatal loss. This paper and the findings have the ability to assist with further
research and meaningful interventions with this population on a challenging
subject. 
There are just a few clarifying questions and comments I have, but I believe this
paper would make a valuable contribution to the literature with these changes.
Introduction:
1) Typos: Line 75 should be couples.
2) The last sentence of the introduction shows the population of focus is in
Japan. Could you provide some additional literature in the introduction that
shows the inherent literature gaps on studying CG risk factors in perinatal loss in
this population?
Methods:
1) I appreciate the additional information provided regarding ethical information
and processes based on prior review. Do you have data on the number (and
percentage) of individuals who opted out? 
2) The pieces contained in data collection regarding hypotheses should be more
appropriately placed into the end of the introduction.
3) Please separate the measures into distinct sections rather than in data
collection to allow for ease of reading. 
4) Was the SCID used to classify mental disorders based on the DSM-5 or what
interview was used for this? Please also remember to provide a citation for the
DSM-5 and any measures you include.
5) Please put the website link for the EZR software platform in the references
instead of the body of the text.
6) I am curious why you did not control for multiple previous losses in your
logistic regression or individuals who had a history of infertility?
