What this trial studies

This study investigates the impact of alcohol consumption on sexual communication and the potential link to intimate partner sexual violence (IPSV) among couples. A total of 240 couples, including both sexual minority and heterosexual pairs, will participate in controlled laboratory sessions where their alcohol levels and communication styles will be assessed. Participants will undergo breath tests and sobriety checks to ensure compliance with study protocols. The study aims to shed light on how alcohol influences communication dynamics and the risk of IPSV.

Who should consider this trial

Good fit: Ideal candidates are couples aged 21 to 65 who identify as either cisgender heterosexual or cisgender sexual minority individuals and have engaged in sexual activity within the past month.

Not a fit: Patients who do not identify as cisgender or are not in a committed intimate relationship may not benefit from this study.

Why it matters

Potential benefit: If successful, this research could lead to improved interventions for reducing intimate partner sexual violence by understanding the role of alcohol in communication.

How similar studies have performed: While studies on alcohol and communication exist, this specific focus on IPSV among diverse couple types is relatively novel and underexplored.
