Because the presence of some past year stressful life events overlaps with DSM-5 criteria for SUD, we removed five overlapping stress items from an exploratory analysis (see Table 1: Items 2, 3, 4, 6, and 7). In this exploratory binary logistic regression analysis, we reanalyzed the data with and without these five items added as covariates. Additionally, we explored associations between specific types of stressful life events, gender, and transitions in past year DSM-5 SUD diagnoses. We collapsed the 16 stressful life events into four categories of stressors: interpersonal problems or loss, job problems or loss, financial problems, and legal- or crime-related stress. These exploratory binary logistic regression analyses included gender as a categorical variable (female vs. male) and each stress category as a categorical variable (zero or one event vs. two or more events) to be consistent with the primary analysis. Both exploratory analyses did not differentially change the pattern of overall results for new vs. absent or ongoing vs. remitted SUD diagnoses or by specific stressor type. However, it should be noted that the financial problems stress category
