Where are the interview date variables?
On each of the baseline files (mothers’ and fathers’) there are two variables you should use to find out when the respondent was interviewed. M1INTMON / F1INTMON represent the month of interview, and M1INTYR / F1INTYR represent the year of interview. There is also a constructed variable (CM1TDIFF) that is found in the mothers’ files and can be used to check the time gap between parent interviews. There are corresponding variables at all waves.
