The Role of Personality Traits in Career Decision-Making

Abstract

This study explored the influence of personality traits on career decision-making using a mixed-methods experimental design that integrated quantitative analysis with qualitative insights. A sample of 500 undergraduate students completed measures of the Big Five personality traits, career decision-making self-efficacy, and career decision-making difficulties. Regression results revealed that conscientiousness and openness were significant positive predictors of self-efficacy, while neuroticism was strongly associated with heightened decision-making difficulties. ANOVA analyses highlighted meaningful differences across academic disciplines, suggesting that certain fields attract distinct trait profiles. Post-intervention findings demonstrated that personality-focused career counseling workshops significantly improved decision-making clarity and self-confidence among participants. Longitudinal follow-up confirmed that these improvements were sustained over time. Qualitative data from interviews and focus groups supported the quantitative outcomes, with students reporting that self-awareness of traits enhanced their sense of vocational fit, adaptability, and coping strategies in career planning. Visualizations and statistical tables consistently showed robust links between personality and career outcomes, with conscientiousness and openness emerging as the most beneficial traits. The integration of both strands affirms that embedding personality assessment into career counseling can reduce decision-making difficulties and enhance adaptability. These findings provide strong evidence for personality-informed frameworks in higher education career guidance, promoting effective, confident, and sustainable career trajectories.
