Using actor-partner interdependence modeling to understand recent illicit opioid use and injection drug use among men in community supervision and their female partners in New York City

Background: The United States’ opioid crisis disproportionately affects individuals in the criminal justice system. Intimate partners can be a source of social support that helps reduce substance use, or they can serve as a driver of continued or increased substance use. Better understanding of the association between intimate partner characteristics and illicit opioid use and injection drug use among individuals in community supervision could be vital to developing targeted interventions. Methods: Using actor-partner interdependence models, we examined individual and partner characteristics associated with recent illicit opioid use and injection drug use among males in community supervision settings in New York City (n = 229) and their female partners (n = 229). Results: Higher levels of depression (aOR 1.98, 95% CI [1.39–2.82], p ≤ 0.01) and anxiety (aOR 1.98, 95% CI [1.42–2.75], p ≤ 0.01) were associated with recent opioid use among males in community supervision. Females with a partner having higher levels of anxiety were more likely to have recently used opioids (aOR 1.52, 95% CI [1.06–2.16], p ≤ 0.05). Males with a female partner with higher levels of anxiety (aOR 2.16, 95% CI [1.31–3.56], p ≤ 0.01) or depression (aOR 1.70, 95% CI [1.01–2.86], p ≤ 0.05) were more likely to recently inject drugs. Women with a male partner who had been in prison were more likely to have recently injected drugs (aOR 3.71, 95% CI [1.14–12.12], p ≤ 0.05), but women who had a male partner who had been arrested in the past three months were less likely to have recently injected (aOR 0.08, 95% CI [0.02–0.46], p ≤ 0.01). Conclusions: Results suggest that recent individual illicit opioid use and injection drug use is associated not only with individual-level factors, but also with partner factors, highlighting the need for couple-based approaches to address the opioid epidemic.
