There are up to four time points for each individual in the sample; the sample size for each relationship status refers to total number of time points at which this status was reported.

Note: Within each row, means with the same superscript are significantly different from one another (p < .05) based on results from multilevel models that adjust for dependency of time points within individuals and control for educational, residential, parenthood, and employment status.
