Understanding suicidal ideation requires examining its links with meaning in life and affect. Network analysis identified key factors like the search for meaning and positive affect as crucial targets for interventions.
Area of Science:
- Psychology
- Mental Health Research
- Network Analysis in Psychopathology
Background:
- Holistic analysis of psychopathology may limit understanding.
- Fine-grained analysis is needed to explore complex relationships.
Purpose of the Study:
- To investigate dimension-level relationships between suicidal ideation, meaning in life, and affect.
- To identify potential prevention and intervention targets for suicidal ideation using network analysis.
Main Methods:
- Network analysis of self-report data from 852 healthy adults (aged 18-35).
- Assessment of suicidal ideation, meaning in life, and affect.
- Calculation of network centrality and bridge influence.
Main Results:
- Suicidal ideation prevalence was 4.2%.
- Meaning in life (search and presence) and affect (positive and negative) showed complex links with suicidal ideation dimensions (pessimism, sleep, despair).
- Key central nodes included search for meaning, sleep, despair, and positive affect. Critical bridge nodes were positive affect, negative affect, and presence of meaning.
Conclusions:
- Meaning in life and affect play distinct roles in suicidal ideation.
- Identified network nodes offer promising targets for prevention and intervention strategies.
