PROJECT SUMMARY
Factors that lead to suicidal thoughts and behaviors (STBs; i.e., passive or active suicidal ideation,
behaviors, plans, gestures, or attempts) are complex. An important factor in suicide deaths and attempts is
alcohol use; up to 36% of completed suicides involve acute alcohol use, while those with AUD may account for
up to 20-40% of suicides. Despite this relationship, processes that may underlie the two are unclear. A
common variable between alcohol use and STBs appears to be behavioral economic decision-making such as
delay discounting (i.e., the devaluing of a commodity as a function of time). However, other forms of
discounting (i.e., probability; devaluing an outcome based on its likelihood, social; devaluing an outcome based
on the closeness of another) have not been explored in their relation to alcohol use and STBs despite their
potential relevance to alcohol use and STBs. Probability discounting, considered a proxy of risky choice,
should be related to increased alcohol use and more severe STBs due to the inherent risk involved in a suicide
attempt. Social discounting, a proxy of altruistic choice, should have relations to broader theories of addiction
such as the contextual reinforcer pathology model. Losses of close social supports, through suicide or
overdose death, could result in allocation towards further alcohol use, which could affect decision-making and
therefore increase suicide risk. Behavioral economic demand (i.e., higher willingness to continue to purchase
and consume a commodity at increasing prices) for alcohol may also be an indicator of STBs and suicide risk.
Furthermore, behavioral economic decision-making has been predictive of engagement with and success of
substance use treatment. Therefore, the purpose of this study is to examine how alcohol use and
passive/active suicidal ideation covary over time and also to determine the effectiveness of remote, self-guided
CBT4CBT modules for alcohol use and its affect on STBs.
