Closeness Discrepancies and Intimacy Interference: Motivations for HIV Prevention Behavior in Primary Romantic Relationships.

Relational closeness has been positively associated with relationship quality and mental health; however, desire for closeness and intimacy in a relationship may also motivate sexual risk-taking, that is, forgoing condom use. This study examined the impact of desiring more closeness with a primary partner (i.e., motivation for reducing closeness discrepancies) on HIV prevention behavior. Using pre-exposure prophylaxis (PrEP) as a case study, we examined the extent to which closeness discrepancies motivate behavioral intentions (Study 1) and actual behavior (Study 2). In both studies, desiring more closeness and believing that condoms interfere with intimacy were independently positively associated with PrEP adoption. Understanding the relational needs for closeness and intimacy in motivating prevention behavior is critical for social psychology, relationship science, and public health efforts to improve sexual health.
