Significantly better performance on the Opioid Overdose Knowledge Subscale ( R 2 = 0.04, F [6, 469] = 3.5, P < 0.01) was associated with not being an illicit opioid user ( b = 0.10, t [469] = 2.14, P = 0.03) and being younger than 30 ( b = 0.13, t [469] = 2.82, P < 0.01); not being trained to deliver naloxone approached significance ( b = 0.10, t[469] = 1.95, P = 0.051), and being male, having experienced more lifetime overdoses, and being trained to deliver naloxone had no significant contribution to performance.
