There is long-standing evidence that acquired capability and emotion regulation are key to understanding the progression from self-harm to suicide (Law et al., 2015; Turton et al., 2021; Van Orden et al., 2010). However, recent literature suggests that emotion dysregulation alone is not a sufficient explanation for non-suicidal self-injury (NSSI) and suicidality. Research has demonstrated that emotion-regulation self-efficacy (ERSE), or the belief in one's ability to regulate one's emotions (e.g., Gratz et al., 2020), is a factor in predicting the pathway between NSSI and suicidal behavior (Gratz et al., 2020). The purpose of this project was to examine the relationship between emotion reactivity, ERSE, NSSI, acquired capability, and suicidal thoughts and behaviors. Participants were asked to complete a screener and those who endorsed self-harm history were eligible to complete the follow-up questionnaire (N = 174). Findings indicated that ERSE is lower among people with history of NSSI and either suicidal ideation or suicide attempt history, as compared to those with only a history of NSSI. In addition, ERSE is negatively associated with emotion reactivity such that those with greater emotion reactivity have lower ERSE. ERSE predicted suicidal risk over and above emotion reactivity, acquired capability, and number of NSSI methods. Last, ERSE for positive affect predicted suicidal risk over and above emotion reactivity and acquired capability, such that those with lower ERSE have higher suicidal risk. Implications of these findings point to ERSE as a predictor for suicidal risk.
