Opioid use among individuals in intimate relationships.

Relationships and social support have direct effects on opioid misuse, which is highly prevalent and associated with morbidity and mortality. However, there is a dearth of research focusing on the characteristics and quality of intimate relationships in the context of opioid misuse, which is important for informing interventions with the dual target of improving intimate relationships and reducing opioid use. The current study surveyed individuals with opioid misuse who are in intimate relationships to characterize how they perceive (1) their relationship functioning and (2) how their intimate partners impact their opioid use. Individual participants (<i>N</i>=93) were recruited from Amazon's Mechanical Turk (mTurk) and answered quantitative survey questions related to their opioid and other substance use, intimate relationship quality and functioning, and intimate partners' behaviors in relation to their opioid use. Opioid misuse severity significantly differed by sexuality and rates of polysubstance use were high in this sample. Many participants reported low relationship quality and intimate partner violence in their relationship. Some participants reported using opioids with their intimate partners (33.3%) and having an intimate partner who had overdosed on opioids (15.1%). Many participants also reported that arguments with intimate partners impacted their opioid cravings (52.7%) and that they have an interest in couples treatment for opioid use (80.7%). Findings highlight links between intimate relationships and opioid misuse and identify areas in which behavioral treatments may be adapted to address the needs of couples with OUD. Future research should replicate the current findings in larger and more diverse samples.
