People experiencing suicidal thoughts often struggle with understanding their emotions. New research shows a lack of knowledge about emotion sources is linked to suicidal thinking and perceived emotion regulation difficulties.
Area of Science:
- Psychology
- Neuroscience
- Mental Health
Background:
- Suicidal thoughts affect approximately 9% of the population.
- Suicidal ideation is linked to perceived emotion regulation deficits.
- Factors underlying these perceptions are not fully understood.
Purpose of the Study:
- To investigate the relationship between knowledge of emotion sources and suicidal thoughts.
- To explore if low source attribution of emotion contributes to emotion regulation difficulties in individuals with suicidal ideation.
Main Methods:
- Two ecological momentary assessment studies (N=396, N=195) were conducted.
- Participants reported on their emotions, suicidal thoughts, and emotion regulation.
- Language processing analyzed written descriptions of emotion sources.
Main Results:
- Individuals with suicidal thoughts demonstrated less knowledge about the sources of their emotions.
- Lower source attribution of emotion was associated with more frequent and prolonged suicidal thoughts.
- Perceived emotion regulation success mediated the link between source attribution and suicidal thoughts.
Conclusions:
- Reduced knowledge about the sources of negative emotions may increase the risk of suicidal thinking.
- Interventions aimed at improving emotion source attribution could potentially mitigate suicidal ideation.
- Understanding the cognitive underpinnings of emotion regulation is crucial for suicide prevention.
