Discrepant substance use and marital functioning in newlywed couples.

Area of Science:

• Social Psychology
• Marital Studies
• Substance Use Research

Background:

• Marital functioning is influenced by various factors, including partner behaviors.
• Substance use (smoking, drinking, drug use) is a common behavior within relationships.
• Understanding the impact of differing substance use patterns on marital quality is crucial, particularly during the critical transition to marriage.

Purpose of the Study:

• To examine the implications of discrepant husband and wife substance use on relationship quality.
• To investigate how differing patterns of smoking, drinking, and drug use affect marital satisfaction at the start of a marriage.

Main Methods:

• Surveyed 642 couples newly entering their first marriage.
• Utilized separate, self-administered questionnaires completed by each partner at home.
• Analyzed data on smoking, alcohol consumption, and drug use patterns.

Main Results:

• Couples where only one partner reported heavy drinking or drug use experienced significantly lower marital quality.
• This effect was observed for both husbands and wives reporting lower relationship satisfaction.
• Interactions between husband and wife use were not significant for cigarette use, alcohol use, or regular drinking, suggesting discrepancies in deviant behaviors are key.

Conclusions:

• Discrepancies in substance use behaviors, particularly heavy drinking and drug use, are strongly associated with reduced marital quality.
• The configuration of partners' substance use patterns, rather than just individual use, is critical to marital functioning.
• These findings highlight the importance of addressing substance use differences for relationship success during the transition to marriage.
