“…As compared to SSAs, MSAs also seem to exhibit a greater number of suicide risk factors (e.g., a history of childhood emotional abuse and family suicide), increased psychopathology (e.g., depression and substance abuse), higher levels of suicidality (e.g., SI), and lower interpersonal functioning. As compared to SSAs, MSAs had significantly higher motor impulsivity, indicating spur-of-the-moment action (13,14). MSAs also had a longer duration of bipolar illness, more frequently lived alone, had more than one psychiatric comorbidity, and were more likely to attempt suicide by self-poisoning (although this is also the most common suicide method in SSAs) (15).…”

Clinical Differences Between Single and Multiple Suicide Attempters, Suicide Ideators, and Non-suicidal Inpatients

et al. 2020

Single suicide attempters (SSAs) and multiple suicide attempters (MSAs) represent distinct subgroups of individuals with specific risk factors and clinical characteristics. This retrospective study on a sample of 397 adult psychiatric inpatients analyzed the main sociodemographic and clinical differences between SSAs and MSAs and the possible differences between SSAs, MSAs, and psychiatric patients with and without suicidal ideation (SI). Clinical variables collected included psychiatric diagnoses (Mini International Neuropsychiatric Interview), presence of substance use, current suicide risk status (Columbia Suicide Severity Rating Scale), Clinical Global Impression at admission, Global Assessment of Functioning improvement between admission and discharge, age at onset of psychiatric illness, duration of untreated illness in years, number of hospitalizations in psychiatric settings, and lethality of the most severe suicide attempt. A multinomial logistic regression model with groups showed that MSAs had a higher lethality of their last suicide attempt as compared to SSAs. In addition, MSAs had distinct sociodemographic characteristics compared to both SSAs and patients with SI. Although the study was limited by the relatively small sample size and retrospective nature, the present results suggest that identifying MSAs could be useful in predicting suicide risk and designing ad hoc prevention strategies.

“…Impulsivity is a common feature of several psychiatric disorders [ 36 ], such as bipolar disorder (BD) [ 37 ] and Cluster B personality disorders [ 38 ], particularly borderline personality disorder [ 39 , 40 ]. Moreover, motor impulsivity was reported to differentiate multiple- from single suicide attempters [ 41 ]. However, our study did not assess early life and recent stressful life events, which appear to mediate the relationship between impulsivity and SB [ 42 , 43 ], in line with the so-called Interpersonal Theory of Suicide (IPTS) [ 44 ].…”

The association of aggression and impulsivity with suicidal behavior (SB) in depression may vary across countries. This study aimed (i) to compare aggression and impulsivity levels, measured with the Brown-Goodwin Scale (BGS) and the Barratt Impulsivity Scale (BIS), respectively, between New York City (NYC) (US), Madrid (Spain) and Florence (Italy) (ANOVA); and (ii) to investigate between-site differences in the association of aggression and impulsivity with previous SB (binary logistic regression). Aggression scores were higher in NYC, followed by Florence and Madrid. Impulsivity levels were higher in Florence than in Madrid or NYC. Aggression and impulsivity scores were higher in suicide attempters than in non-attempters in NYC and in Madrid. SB was associated with aggression in NYC (OR 1.12, 95% CI 1.07–1.16; p < 0.001) and in Florence (OR 1.11, 95% CI 1.01–1.22; p = 0.032). Impulsivity was linked with SB in NYC (OR 1.01, 95% CI 1.00–1.02; p < 0.001) and in Madrid (OR 1.03, 95% CI 1.02–1.05; p < 0.001). The higher suicide rates in NYC, compared to Madrid or Florence, may be, in part, explained by these cross-cultural differences in the contribution of aggression-impulsivity to SB, which should be considered by future research on SB prevention.

“…Impulsivity is defined as a combination of lack of premeditation and perseverance, sensation-seeking, and urgency (Whiteside, Lynam, Miller, & Reynolds, 2005). In psychiatric patients, self-measured motor impulsivity can distinguish between patients with and without history of suicide attempt (Ponsoni et al, 2018) and with history of single and multiple suicide attempts (LaCroix et al, 2017). Furthermore, two distinct forms of impulsivity have been identified.…”

In humans, suicide overrides the basic instinct of survival that is common to the vast majority of known life forms. This phenomenon has frightened and fascinated philosophers throughout history. This virtually exclusively human behaviour has been and still is a major issue worldwide, thus explaining its place first in religious and philosophical doctrines, then in sociology and philosophy, and currently in biology and medicine.
