a difference between CATI and MQ was significant (p-value <0.05).

b the denominator for permission rate is the number of mothers who participated.

c among fathers that project staff were given permission to contact.

d among all fathers potentially eligible for participation at the beginning of HOEPS. Fathers were lost to participation when the mother did not participate, when the mother did not give permission to contact the father, when contact information could not be found for the father, and when the father chose not to participate.
