Note.

5 -HTTLPR (H1) (0 = long/long; 1 = short/long, short/short).

5 -HTTLPR (H2) (0 = short/long, long/long; 1 = short/short). Results from regression analyses controlling for depression, ethnicity, gender, cohort, education, negative emotional behavior, and marital satisfaction at T1. Standard errors corrected for clustering within couples.
