Reviewer's  report:  
 
This manuscript  aims  to evaluate  the psychometric  properties  of the Swedish  version of the EHP - 
30. I appreciated  the methodology of this study and the conclusions  appear  well supported by the 
reported data.  
 
Howeve r, some  points  should be further  investigated  by the Authors, as reported below:  
 
1)Style  and syntax require  editing/correction  throughout  the manuscript. 
2)I suggest  further  expanding reference list mentioning these  recent  studies  about  pathogenesis  of 
endometriosis:  doi: 10.1016/j.mehy .2017.03.032;  doi: 10.1155/2018/7924021. 
3)As  mentioned by the authors, chronic  pelvic  pain (CPP)  is one of the most  common  clinical 
signs  of endometriosis  together  with menstrual  irregularities,  dysmenorrhea, dyspareunia  and 
infertility . As correctly  underlined by the Authors, symptoms  of endometriosis  often  affect 
psychological  and social  functioning of patients.  For this reason, endometriosis  is considered as a 
disabling condition that may significantly  compromise  social  relationships,  sexuality  and mental 
health. I truly  think that the Authors  should further discuss this topic, referring  to: doi: 10.5301/ 
je.5000274;  doi: 10.23736/S0026- 4806.19.0 6298- 0; doi: 10.23736/S0026- 4806.19.06299- 2.
