Does Drinking Together Promote Relationship Intimacy? Temporal Effects of Daily Drinking Events

Although research has documented harms associated with drinking within intimate relationships, there is evidence that some drinking patterns-characterized by congruent or shared partner drinking-may be associated with positive relationship functioning. The present dyadic daily diary study allowed us to consider whether congruent drinking events and drinking with partner increase the likelihood of experiencing intimacy with one's partner within the next few hours.

Within a sample of 119 community couples in which both partners drank regularly, we studied the temporal relationship between drinking events and intimacy experiences using 56 days of daily reports. To ensure that the pattern of results was robust, we tested the effects of congruent versus noncongruent drinking events using different characterizations.

Drinking episodes involving simultaneous drinking by both partners (but not solo drinking) increased the likelihood of intimacy in the next few hours. Similarly, drinking episodes in which partner was present (but not episodes when partner was absent) and drinking episodes that took place at home (but not away from home) increased the likelihood of intimacy.

Results provide the first evidence that some types of drinking events contribute to the occurrence of couple intimacy experiences within the next few hours and help to explain previously observed long-term effects of congruent drinking patterns on couple functioning.
