Abstract: This study examined the moderating role of narcissism in the relationship between negative emotional states and everyday creativity. Using the day reconstruction method, 404 participants were assessed over five consecutive days on emotional states, daily creativity state, and daily creative behaviors. Hierarchical linear modeling was used to analyze the nested data. Results showed that narcissistic traits significantly predicted daily creative behavior, and negative emotions were negatively associated with both daily creativity state
and behavior. Moreover, narcissism significantly and negatively moderated the link between negative emotion and daily creativity state. Simple slope analysis revealed that individuals with high narcissistic traits experienced a stronger decline in creativity state under negative emotional conditions. These findings offer new insights into the dynamic influence of emotional states on everyday creativity and highlight the role of personality traits in this process.

Key words: narcissism, emotional states, everyday creativity, day reconstruction method
