Objective · To explore the effect of emotional intelligence on the behavioral performance in crisis intervention, taking the knowledge and skills learning performance of crisis intervention as the mediating variable. Methods · Based on the sequential pattern analysis and comprehensive evaluation of learning performance in the previous study, Emotional Intelligence Scale was used to collect the emotional intelligence of 104 mental health service personnel. The mediating effect model was used to analyze the relationship among personal traits, learning performance and behavior performance. Results · There was no direct correlation between emotional intelligence and behavior performance (r-0.016, P0.869). The knowledge and skills learning performance of crisis intervention in identifying problems, providing support and coping strategy played a complete mediating role between emotional intelligence and behavior, with indirect effects of a1b1-0.052 (P0.010, 95% CI -0.126 - -0.010), a2b20.139 （P0.000, 95% CI 0.063 - 0.259), and a3b30.087 (P0.012, 95% CI 0.019 - 0.186). Conclusion · Emotional intelligence interferes in behavioral patternaffecting crisis intervention learning performance, but influence relationships are inconsistent.
