Testing the robustness of daily associations of affect with alcohol and cannabis use.

ABSTRACT: Etiological models of alcohol and cannabis use disorders hypothesize that people are more likely to use substances when experiencing heightened negative affect, yet recent Ecological Momentary Assessment (EMA) studies found no evidence for this daily association. To provide a robust understanding of whether and when affect regulation is supported in EMA, we tested within-person associations between affect and substance use across hundreds of statistical models in a diverse sample of young adults (n = 496) recruited from both college and community sources, aged 18-22 years (55.8% assigned female sex at birth, 44.2% assigned male sex at birth; 47.2% cisgender female, 43.8% cisgender male, 12.9% nonbinary/genderqueer/gender nonconforming, 4.0% transgender; 69.6% non-Hispanic White, 26.
