Abstract Details

2017, Master of Arts, Miami University, Psychology.
Several models of suicidal behavior posit that in order to transition from suicidal ideation to attempting suicide, individuals must have an acquired capability for suicide (ACS). ACS is hypothesized to develop through exposure to painful and provocative experiences which lead to elevations in fearlessness about death and physical pain tolerance, thus preparing a person to enact serious self-harm. Although ACS is hypothesized to increase monotonically, recent research suggests that ACS may exhibit decreases over the short-term for some individuals (Zuromski, Cero, & Witte, 2015), and that ACS may have a "set point" to which it returns following fluctuations (Bryan, Sinclair, & Heron, 2015). The current study examined the nature of change in ACS over time within a sample of eating disorder inpatients. Growth mixture modeling to test models of fearlessness about death and pain tolerance identified that for both factors, a one-class intercept-only model was the best-fitting model, suggesting that patients entered treatment with mid-level ACS and experienced no significant linear change over the course of treatment. These findings suggest that ACS may be more stable than previously hypothesized, drawing attention to the importance of future research examining ACS across different time scales.
