Suicide-related behaviors and opioid misuse are co-occurring major public health problems that are responsible for decreased life expectancy. Despite advances using public health data on understanding the prevalence of both behaviors' co-occurrence, there is a lack of research explicating why opioid use is associated with heightened suicide and suicide attempt risk. Contemporary models of self-injurious behavior suggest several variables predictive of suicidal behavior that may have relevance for opioid misuse: increased negative self-appraisal, decreased social norm espousal, fearlessness about death, pain habituation, and practical capability, or knowledge and familiarity with lethal means. Given that prior research has associated opioid misuse with elevated levels of these risk factors, they may explain the association between opioid misuse and suicide-related behavior. Further, to distinguish if any observed association is unique to opioid misuse, it is important to compare associations with other substances robustly associated with suicide risk, such as alcohol. To address this research gap, a community sample of participants with lifetime suicide ideation (N=283) was recruited across three groups: those with opioid misuse (n=99; Opioid group), alcohol misuse (n=80; Alcohol Group) and no problematic substance use (n=104; No Substance Misuse group). Participants completed self-report measures assessing characteristics of suicide risk (e.g., suicide ideation, planning and attempt) and assessing the above risk factors hypothesized to account for the link between opioid misuse and suicidal thoughts and behaviors. All examined factors except pain tolerance were associated with suicide risk characteristics. Only increased negative self-appraisal (measured by self-criticism and self-hate), and practical capability were statistically different across groups, such that Opioid group participants reported: (1) significantly less self-criticism than Alcohol group pa (open full item for complete abstract)
