	| Hi, 
 I am a PhD student working in the field of female genital cutting (FGC).
 We are planning a cluster randomized intervention study to investigate knowledge, attitudes and practice of FGC.
 
 For the sample size calculation we need to estimate the design effect (or the intracluster correlation coefficient).
 I have found that DHS publish design effect for some of the questions used in the questionnaire. But I have not found this reported for the questions in the Female Genital Cutting Model.
 Is this information available somewhere?
 
 Much grateful for an answer!
