About this trial
This study examines the role of alcohol use in understanding the dynamics of romantic relationships. Couples will participate in a research session where they consume either an alcoholic or non-alcoholic beverage and complete study tasks. After the session, participants will provide information about their drinking habits, alcohol- and non-alcohol-related experiences, and relationship factors through brief surveys on their smart phones and again at 6-month and 12-month follow-up sessions. The findings from this study aim to improve understanding of alcohol use in close relationships and may inform future strategies for promoting healthier relationships and behaviors.

Trial outcomes
Primary outcomes
Social behaviors-observational
Behavioral measures of social processes using validated and reliable behavioral coding schemes to code facial expressions, speech behaviors, and speech content: the Facial Action Coding System (Ekman, Friesen, \& Hagar, 2002) and the Rapid Marital Interaction Coding System (Heyman, 2004). This coding uses binary (yes/no) codes for presence/absence of behaviors at each moment in time. Higher scores represent more instances of behaviors.
Emotions
The 8-item Mood Measure (Fairbairn et al., 2021) will assess self-reported positive and negative emotions on scales from 0 (none) to 10 (extremely). Higher scores indicate a greater intensity of emotions.
Social behaviors-self-report
Participants will provide ratings of their own and their partners' social behaviors on ten-point Likert scales. Higher scores indicate a greater endorsement of each behavior.
Real-world experiences
Ecological Momentary Assessment (EMA) methods will be used to send a series of brief surveys to participants' smartphones to assess alcohol consumption (in standard alcoholic drinks).
Secondary outcomes
Relationship functioning
Relationship functioning will be assessed on 10 point Likert scales (Jakubiak \& Feeney, 2009), with higher scores representing higher relationship functioning.
