Abstract
Suicide prevention represents a global imperative, and efforts to identify potential risk factors are intensifying. Among these, emotional regulation abilities represent a transdiagnostic component that may have an impactful influence on suicidal ideation and behavior. Therefore, the present systematic review aimed to investigate the association between emotion dysregulation and suicidal ideation and/or behavior in adult participants. The review followed PRISMA guidelines, and the research was performed through four major electronic databases (PubMed/MEDLINE, Scopus, PsycInfo, and Web of Science) for relevant titles/abstracts published from January 2013 to September 2023. The review included original studies published in peer-reviewed journals and in English that assessed the relationship between emotional regulation, as measured by the Difficulties in Emotional Regulation Scale (DERS), and suicidal ideation and/or behavior. In total, 44 studies were considered eligible, and the results mostly revealed significant positive associations between emotion dysregulation and suicidal ideation, while the findings on suicide attempts were more inconsistent. Furthermore, the findings also confirmed the role of emotion dysregulation as a mediator between suicide and other variables. Given these results, it is important to continue investigating these constructs and conduct accurate assessments to implement effective person-centered interventions.
Here are some thoughts. I used this research in a recent article.
This systematic review explores the role of emotion dysregulation in understanding suicide risk among adults, analyzing 44 studies that assess the association between emotional regulation difficulties—measured primarily by the Difficulties in Emotion Regulation Scale (DERS)—and suicidal ideation and behavior. The findings largely support a significant positive correlation between emotion dysregulation and suicidal ideation across both clinical and nonclinical populations. Specific dimensions of emotion dysregulation, such as impulsivity, lack of emotional clarity, and ineffective use of regulatory strategies, were particularly linked to increased suicidal thoughts. However, results regarding suicide attempts were more inconsistent, with some studies showing a strong link while others found no significant associations.
The review also highlights the mediating role of emotion dysregulation between various risk factors (e.g., childhood trauma, psychopathy, depression) and suicidal outcomes. Emotion dysregulation appears to amplify suicide risk by influencing how individuals cope with psychological pain and stress. Despite methodological limitations—including reliance on self-report measures, sample heterogeneity, and limited longitudinal data—the evidence suggests that improving emotional regulation could be a valuable target for suicide prevention strategies. The authors recommend further research using robust statistical methods and comprehensive assessments to better understand causal pathways and enhance intervention effectiveness.
