Personality traits and academic performance: Correcting self-assessed traits with vignettes.

Area of Science:

• Educational Psychology
• Behavioral Economics

Background:

• Student performance in higher education is influenced by non-cognitive skills.
• Accurate measurement of personality traits like Conscientiousness, Emotional Stability, and Risk Preference is challenging due to heterogeneous scale use.

Purpose of the Study:

• To investigate the relationship between Conscientiousness, Emotional Stability, and Risk Preference and student performance.
• To assess the impact of correcting for heterogeneous scale use on these relationships using anchoring vignettes.

Main Methods:

• Data collected from first-year students at a Dutch university.
• Anchoring vignettes employed to adjust for individual differences in scale interpretation.
• Statistical analysis to compare corrected and uncorrected estimates of personality traits on academic performance.

Main Results:

• Conscientiousness shows a significant positive relationship with student performance, with uncorrected estimates exhibiting upward bias.
• No significant relationship found for Emotional Stability, though uncorrected estimates were larger.
• Risk Preference demonstrates a negative relationship with performance, entirely explained by scale use correction.

Conclusions:

• Objective measurement of personality traits is essential for accurate assessment of their impact on student performance.
• Anchoring vignettes effectively mitigate bias caused by heterogeneous scale use in non-cognitive skill assessment.
• Conscientiousness is a key predictor of academic success, emphasizing the need for reliable measurement tools.
