Abstract
Personality traits and social, emotional, and behavioral (SEB) skills are closely related but incrementally predict life outcomes. This implies that although tightly connected, what a person tends to do (personality traits) and what they are capable of doing (skills) are not always perfectly aligned. In this study, we investigated whether matches and mismatches between traits and skills predict important life outcomes. We studied a diverse sample of high school students (N = 840) who self-reported their Big Five personality traits, five SEB skill domains, and an array of academic, social, and emotional outcomes. Using response surface analysis, we found that matching trait/skill levels did not confer a unique benefit for adolescents over the additive effects of traits and skills. In contrast, we found that trait/skill mismatches predicted outcomes, and in some cases, adolescents with mismatching trait/skills had the best and worst outcomes. Specifically, youth with higher skill levels relative to their traits reported better outcomes, and those with lower skills relative to their traits reported worse outcomes. Our findings provide insights into functioning that are missed by solely focusing on direct effects and show that SEB skills can enhance youth’s personality strengths and buffer against shortcomings.
Plain language summary
Personality traits are how a person tends to think, feel, and behave, whereas social, emotional, and behavioral skills are how someone is capable of acting at their best. Although personality traits and skills are related, what people tend to do and what they are capable of doing are not always perfectly aligned. Some theories propose that people will have better life outcomes if they have matching levels of traits and skills, meaning they tend to act in ways that match their capabilities. Other theories propose that people will have better outcomes if they have mismatching trait and skill levels, meaning they are capable of acting at higher levels than they usual act. This study tested these competing hypotheses in a sample of 840 high school students. Results only supported the benefits of mismatching trait and skill levels. Specifically, we found that youth with higher skill levels relative to their traits reported better academic, social, and mental health outcomes. Additionally, we found that having high skills and high trait levels predicted better outcomes, even though having matching levels did not provide additional benefits. Together, our study suggests that having high skill levels can help people compensate for personality shortcomings and that having high levels of traits and skills can enhance someone’s outcomes by allowing them to fully capitalize on their personality strengths.
