Affect lability and trait anxiety are key factors in suicidal ideation among major depressive disorder patients. Identifying these central nodes can aid in early detection and treatment of suicidal behavior.
Area of Science:
- Psychiatry and Behavioral Sciences
- Clinical Psychology
Background:
- Understanding suicidal behavior requires analyzing risk factors in clinical populations.
- Suicidal ideation (SI) and its complex interplay with other factors are crucial for effective intervention.
Purpose of the Study:
- To explore the associations among suicidal ideation (SI), affect lability, and other suicide risk factors.
- To compare network structures and node centrality in single versus multiple suicide attempters with major depressive disorder (MDD).
Main Methods:
- Network analysis of 323 suicidal attempters diagnosed with MDD.
- Examination of associations between SI, affect lability, trait anxiety, hopelessness, and harm avoidance.
- Comparison of network structures across different clinical profiles (single vs. multiple attempters, low vs. high SI).
Main Results:
- Suicidal ideation (SI) was significantly associated with trait anxiety and hopelessness.
- Affect lability (anxiety-depression shifts), trait anxiety, and harm avoidance emerged as central nodes in the network analysis.
- Distinct network differences were observed between repeat and non-repeat suicide attempters, with higher network density in individuals with high SI.
Conclusions:
- Affect lability and trait anxiety are central to the network of suicidal behavior in MDD patients.
- These identified central nodes may serve as valuable targets for early detection and therapeutic interventions in at-risk individuals.
