Marital satisfaction in covenant versus standard marriages: Is there a difference?

After the rapid increase of the American divorce rate in the late 20th century, one of the most conspicuous efforts of the marriage movement in the 1990s that was used to increase marital stability was the legislation of the covenant marriage license, a more restricted marriage license issued in three different states of the U.S. To investigate the marital life of newlywed covenant versus standard couples, a large-scale 5-year couple study was conducted between 1998 and 2003 in Louisiana. The present study uses this large-sample, multiple-wave, multiple-group dyadic dataset to examine differences in co-development and divorce rates in 297 covenant and 380 standard mixed-sex couples using a multiple group growth curve modeling and survival analysis. We examined differences in marital trajectories between covenant and standard couples as well as between husbands and wives in each marital group. The results show (1) that the couples in both groups experienced, on average, declines in marital satisfaction, and such a decline was slower in covenant husbands than their wives as well as those in standard marriages, and (2) that co-development in marital satisfaction was more prominent in standard marriages than in covenant marriages, meaning standard couple's marital satisfaction declined at a more similar rate than that of covenant couples. We provide possible explanations and discuss practical implications.
