“…These results are consistent with findings that show computer-based measures and self-report measures tap into different facets of impulsivity (Cyders & Coskunpinar, 2011). Indeed, self-report measures of impulsivity are more likely to differentiate individuals at risk for self-injurious behavior than computer-based measures (Hamza et al, 2015). …”

“…Another study revealed that individuals with a previous suicide attempt history who reported current suicidal ideation had more disinhibited responses on laboratory measures compared to individuals with a previous suicide attempt history but no current suicidal ideation and also compared to healthy controls (Westheide et al, 2008). However, a recent meta-analysis (Hamza et al, 2015) found that laboratory measures of impulsivity are not consistently related to self-harm. Rather, individuals that engage in NSSI are more likely to self-report impulsivity, and specifically have high negative urgency scores.…”

Rumination has been previously linked to negative psychological outcomes, including depression and suicidal behavior. However, there has been conflicting research on whether or not two different subtypes of rumination – brooding and reflection – are more or less maladaptive. The present research sought to (1) examine whether individuals high in brooding but lower in reflection would show higher trait and behavioral impulsivity, relative to individuals low in brooding and low in reflection; and (2) examine impulsivity as a mediator of the relation between ruminative subtypes and suicidal ideation. In Study 1, participants (N = 78) were recruited based on high, average, and low scores on a measure of brooding and reflective rumination. Individuals who scored high in brooding and average in reflection scored significantly higher in negative urgency, that is, in the tendency to act rashly in an attempt to reduce negative affect, than did those who scored low in brooding and low in reflection. Study 2 (N = 1638) examined the relationship between ruminative subtypes, impulsivity, and suicide risk. We found an indirect relationship between brooding and suicide risk through lack of premeditation and lack of perseverance, independently of reflection. These findings are discussed in relation to cognitive risk for suicide.

“…It is featured in several theoretical models of these self-harm behaviors (Mann et al, 2005; Nock, 2010; van Heeringen and Mann, 2014; Van Orden et al, 2010). Furthermore, it is among the most widely studied constructs in relation to suicide (Wenzel and Beck, 2008), and has been similarly much studied in the context of NSSI (Hamza et al, 2015). Meta-analyses have recently been conducted to evaluate the strength of the association between impulsivity and suicide attempts (Anestis et al, 2014) and NSSI (Hamza et al, 2015), respectively.…”

We conducted a meta-analysis of neurobehavioral and neurocognitive indices of impulsivity in relation to suicidal thoughts and behaviors, as well as non-suicidal self-injury (NSSI). In our systematic review, 34 studies were identified and submitted to a random-effects meta-analysis. A small pooled effect size was observed for the association between behavioral impulsivity and NSSI (OR=1.34, p < .05). A small-to-medium pooled effect size (OR=2.23, p < .001) was found for the association between behavioral impulsivity and suicide attempts, and a medium-to-large pooled effect size was observed for this outcome in relation to cognitive impulsivity (OR=3.14, p < .01). Length of time between suicide attempt and impulsivity assessment moderated the strength of the relation between impulsivity and attempts, with a large pooled effect size (OR=5.54, p < .001) evident when the suicide attempt occurred within a month of behavioral impulsivity assessment. Studies of clinically significant NSSI temporally proximal to impulsivity assessment are needed. Longitudinal research is required to clarify the prognostic value of behavioral and cognitive impulsivity for short-term risk for self-harm.

“…For example, Squeglia and colleagues (2014) have demonstrated that poor inhibitory control predicts early adolescent transition to alcohol use. Self-reported impulsivity, and more specifically negative urgency, has also been linked to self-harm (Hamza et al 2015), although these findings do not translate to laboratory-based measures of impulsivity. Therefore, future research should examine whether the association between EAU and self-harm remains when controlling for personality traits and other dispositional factors.…”

Background Self-harm has considerable societal and economic costs and has been extensively studied in relation to alcohol involvement. Whereas early onset alcohol use (EAU) has been causally linked to maladaptive clinical outcomes, its association with self-harm is less well characterized. The current study aimed to further examine the link between EAU and both non-suicidal self-injury (NSSI) and suicide attempt (SA), and elucidate shared familial and causal/individual-specific pathways that explain this co-occurrence. Methods Using data from 6,082 Australian same-sex twin pairs (1,732 MZ and 1,309 DZ), ages 23-40, we examined prevalence rates of NSSI and SA among twin pairs concordant and discordant for EAU. Conditional logistic regression, controlling for early clinical covariates and the influence of zygosity on EAU, was used to examine the odds ratio (OR) of self-harm within twin pairs discordant for EAU. Results Prevalence rates of both NSSI and SA were highest among twin pairs concordant for EAU and for twins who reported EAU within discordant twin pairs. Results from discordant twin analyses revealed nearly four-fold increased odds of SA for the twin who endorsed EAU, and this OR was equal across monozygotic (MZ) and dizygotic (DZ) twins. EAU also was associated with elevated odds of NSSI (OR=7.62), although this was only the case for DZ twins in discordant pairs. Conclusions The equivalent increase in odds of SA for both MZ and DZ twins suggests that causal or individual-specific influences explain the link between EAU and SA. For NSSI, elevated odds for DZ twins and nonsignificant findings for MZ twins implicate correlated genetic factors in the association between EAU and NSSI. Future studies should test mechanisms through which EAU may causally influence SA, as well as examine whether genetic risk for third variables (e.g., negative urgency, stress reactivity) may explain the genetic overlap between EAU and NSSI.
