Note. TTFI refers to the number of semesters to/from an individual’s first report of first intercourse. AFI1 indicates whether a measurement occasion is 1 semester after an individual’s report of first intercourse (1), all other semesters (0). AFI2+ indicates whether a measurement occasion is 2 or more semesters after an individual’s report of first intercourse (1), all other semesters (0). β= estimated coefficients, SE = standard error.
