Objective: Research indicates a marriage effect with respect to drinking an
d drinking problems. This effect is characterized by less consumption and f
ewer problems among married men and women as compared with either single or
divorced individuals. Method: This article reviews evidence regarding proc
esses that might account for the marriage effect. Results: The literature s
uggests that the marriage effect reflects three processes: (1) reduced alco
hol consumption triggered by the transition to marriage, (2) the deleteriou
s effect of heavy drinking on marital quality and r.,arital stability and (
3) increased consumption in response to the transition to divorce. Conclusi
ons: Given the nature of these transitions, it is argued that transitions t
o marriage and divorce should be viewed as unique opportunities for adult p
revention activities, but that more pre-prevention research focused on chan
ges over these transitions is needed to help target prevention efforts.
