Materials and methods:  
How were the authors asked menstrual changes before and after arrival to China?. ---------  
 
"They were instructed not to write their names on the  
questionnaire and were told that their responses would be confidential.  
Students who agreed to participate were requested to complete a  
questionnaire which inquired about socio -demographic details,  
mens trual pattern characteristics before and after China, and living  
conditions."  
The authors must mentioned about items 4, 5, 7, & 8. There should be simple scoring for PSS. ---
--- 
"To evaluate their stress levels, we incorporated the Perceived Stress Scale(PS S), which asked 
questions about their feelings and thoughts  
during the last month and in each case respondents were asked to rate  
these feelings as: 0 = Never, 1 = Almost Never, 2 = Sometimes, 3 =  
Fairly Often, 4 = Very Often. PSS scores were obtained by r eversing  
responses (e.g., 0 = 4, 1 = 3, 2 = 2, 3 = 1 & 4 = 0) to the four positively  
stated items (items 4, 5, 7, & 8) and then averaging out all scale items."
