Summary
In male inpatients with substance use disorder, borderline personality disorder (BPD) and self-mutilative behavior (SMB) are linked to suicide attempts. SMB, anger, and impulsivity appear to mediate this relationship.
Area of Science:
- Psychiatry
- Psychology
- Addiction Medicine
Background:
- Substance use disorder (SUD) is frequently comorbid with personality disorders.
- Suicide attempts are a significant concern in individuals with SUD.
Purpose of the Study:
- To investigate the association between lifetime history of suicide attempt (HSA) and borderline personality disorder (BPD), aggression, impulsivity, and self-mutilative behavior (SMB) in male inpatients with SUD.
Main Methods:
- 132 male inpatients with alcohol or opioid use disorder were assessed.
- Evaluations included the Buss-Perry Aggression Questionnaire, Barratt Impulsiveness Scale (BIS-11-SF), and SCID-II for BPD.
- Statistical analyses, including linear regression, were performed.
Main Results:
- Individuals with a history of suicide attempts (HSA) had higher rates of BPD, SMB, aggression, and impulsivity.
- BPD, anger, and non-planning impulsivity initially predicted HSA.
- When SMB was included, it became a significant predictor of HSA, alongside anger and non-planning impulsivity, while BPD did not.
Conclusions:
- Self-mutilative behavior (SMB) appears to mediate the relationship between borderline personality disorder (BPD) and history of suicide attempts (HSA) in patients with SUD.
- Anger and non-planning impulsivity may also play a partial mediating role.

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

01:29Psychological and Sociocultural Causes of Schizophrenia

Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...
