Neuroticism Alters How Personality Affects Self-Control

Personality traits like conscientiousness and extraversion are linked to higher self-control, while neuroticism can weaken this effect, especially in specific types of self-control like resisting temptation or initiating proactive behaviors.

These findings could inform strategies for selecting individuals for roles requiring high self-control and designing interventions for personal growth.
