Dr. Anthony Greenham of Southeastern Baptist Theological Seminary did a study of Palestinian MBB's back in 2004 entitled "Muslim Conversions to Christ: An Investigation of Palestinian Converts living in the Holy Land." He interviewed 22 MBB's (11 men and 11 women).
Greenham in Ch 5 provides two lists of categories explaining why Muslims convert:
Lesser Importance are
1) political Instability,
2) Rejection of Islam,
3) Christian Media,
4) Personal Crisis,
5) Community,
6) God’s Honor.
The categories of “Greater Prominance” are
1) Reading the Bible,
2) Role of Believers,
3) Truth of Jesus’ Message,
4) God’s Miraculous Involvement,
5) Person of Jesus.
Update on this: most of Ant Greenham's research and findings were published in an article in St Francis Magazine. Here is THE LINK.
