Unadjusted analyses are presented in the left columns of Table 1. Results (odds ratios, 95% confidence intervals, p-value) show that RA is associated with greater probability of ideation (1.08, 1.04–1.11, p<.01) and attempt (1.08, 1.05–1.11, p<.01). PA is also associated with greater probability of ideation (1.06, 1.03–1.10, p<.01) and attempt (1.09, 1.06–1.12, p<.01). These results indicate that, prior to adjustment for other variables, a one point increase on the RA scale is associated with an 8% (4–11%) and 8% (5–11%) increased probability of ideation and attempt respectively, and a one point increase on the PA scale is associated with a 6% (3–10%) and 9% (6–12%) greater likelihood of ideation and attempt. Probability of both ideation and attempt are also increased among individuals with greater breadth of drug use and higher AUDIT and PHQ-9 scores. Other significant results indicate that attempt is less likely among men and more likely among individuals of “other race/ethnicity,” individuals with < 12 years of education have a greater probability of attempt, and primary “other drug” users have a greater probability of ideation.
