The longitudinal association between personality and achievement in adolescence: Differential effects across all Big Five traits and four achievement indicators

A reciprocal perspective on the differential associations between personality traits and multiple indicators of academic achievement

OBJECTIVE

This study aims to explore the reciprocal associations between personality traits (conscientiousness and openness to experience) and academic achievement in adolescents, using the Personality Achievement Saturation Hypothesis (PASH).

BACKGROUND

Personality traits, especially conscientiousness, and openness, have been identified as strong predictors of academic achievement. The PASH provides a framework for understanding these relationships but has mainly been studied from a unidirectional perspective. This study extends the PASH to examine reciprocal associations and how they vary with different achievement indicators.

METHODS

Using large-scale panel data (N = 6482) of secondary school students in Germany, we applied cross-lagged panel models and latent change score models to examine the differential reciprocal associations between personality traits (conscientiousness/openness) and academic achievement (school grades/achievement test scores) in language and math over two years from grades 7 to 9.

RESULTS

In line with the PASH, initial levels of conscientiousness were more strongly associated with school grades than with achievement test scores over two years. Simultaneously, prior school grades were more strongly associated with conscientiousness over two years. However, initial levels of openness did not show differential associations with either school grades or achievement test scores over two years. Similarly, prior school grades and achievement test scores were also not differentially associated with openness over two years.

CONCLUSIONS

Our findings introduce an innovative lens through which we observe how the PASH can be leveraged to explain the differential reciprocal associations between conscientiousness and academic achievement. Further research is needed to examine if PASH could be similarly extended to disentangle the associations between openness and academic achievement.

Personality, intelligence, and academic achievement: Charting their developmental interplay

OBJECTIVE

Although intelligence and personality traits have long been recognized as key predictors of students' academic achievement, little is known about their longitudinal and reciprocal associations. Here, we charted the developmental interplay of intelligence, personality (Big Five) and academic achievement in 3880 German secondary school students, who were assessed four times between the ages 11 and 14 years (i.e., in grades 5, 6, 7, and 8).

METHOD

We fitted random intercept cross-lagged panel models (RI-CLPs) to investigate reciprocal within-person associations between (a) academic achievement and intelligence, (b) academic achievement and personality, as well as (c) intelligence and personality.

RESULTS

The results revealed negative within-person associations between Conscientiousness and Extraversion assessed at the first wave of measurement and intelligence assessed at the second wave. None of the reciprocal personality-achievement associations attained statistical significance. Academic achievement and intelligence showed reciprocal within-person relations, with the strongest coefficients found for achievement longitudinally predicting intelligence.

CONCLUSIONS

Our work contributes to developmental theorizing on interrelations between personality, intelligence, and academic achievement, as well as to within-person conceptualizations in personality research.

Disentangling the Association Between the Big Five Personality Traits and Student Achievement: Meta-Analytic Evidence on the Role of Domain Specificity and Achievement Measures

Students’ academic achievement is a central predictor of a long list of important educational outcomes, such as access to higher education and socioeconomic success. Prior studies have extensively focused on identifying variables that are related to academic achievement and an important variable in this context appears to be students’ personality. Notably, although findings from more recent studies suggested that the association between student achievement and personality varies by the subject domain (language vs. STEM) and the type of achievement measure (grades vs. test scores), systematic meta-analytical evidence is still lacking. To address this gap in the educational research literature, we conducted a meta-analysis based on 78 studies, with 1491 effect sizes representing data from 500,218 students and 110 samples from elementary to high school. We used a random-effects model with robust variance estimation to calculate mean effect sizes and standard deviations. We found moderating effects of measure or domain for all five personality traits, with differences in the direction of the effects. Our results highlight the importance of the domain and measure when examining how personality traits relate to academic achievement in school. The combination of subject domain and achievement was also found to be relevant for some of the traits. These findings emphasize that subject domains and types of achievement measures should be explicitly considered when investigating the personality saturation of student achievement. We discuss implications for future research, highlighting that there is no “best” or “more objective” achievement measure but, instead, that achievement measures should be chosen based on the research question of interest.

A closer look at the domain-specific associations of openness with language achievement: Evidence on the role of intrinsic value from two large-scale longitudinal studies

BACKGROUND

Many empirical investigations focus on how personality traits and academic motivation are related to academic achievement. Regarding the personality traits described in the five-factor model, prior research has shown associations between openness to experience and language achievement in particular. Following the principle of trait activation, associations with intrinsic value can explain these domain-specific relationships of openness with achievement.

AIMS

This study investigated whether intrinsic value mediates the associations of openness to experience with language achievement to understand these associations more closely. Based on the principle of trait activation, we combined openness to experience with intrinsic value as a motivational construct more proximal to behaviour.

SAMPLES

We capitalized on two large-scale longitudinal data sets (N = 1994; M = 16.8 years; 51% female; and N = 2722; M = 17.34 years; 58% female) of German-speaking students in upper secondary education with two points of measurement, respectively.

METHODS

We assessed achievement using report card grades and standardized test scores, capturing three language subskills: reading and listening, measured by standardized tests, and writing competencies, measured by essay assignments. We conducted mediation analysis using bootstrapped confidence intervals and robust standard errors to account for dependencies in the data due to students clustered within classrooms.

RESULTS AND CONCLUSIONS

Overall, our results show that intrinsic value mediated the relationship between openness and achievement in English as a foreign language. The results remained stable when controlling for prior achievement, predicting achievement gains. Our investigation provides empirical insights into the manifestations of personality in academic contexts. We discuss the limitations of our approach, with a focus on the use of a mediation analysis in this research design.

Conscientiousness and Cognitive Ability as Predictors of Academic Achievement: Evidence of Synergistic Effects From Integrative Data Analysis

Cognitive ability is the most powerful predictor of academic achievement. However, increasing attention is being paid to the role of personality traits in students’ academic achievement. Results indicate incremental effects beyond cognitive ability, especially for conscientiousness. Investigating the interplay of conscientiousness and cognitive ability can increase understanding of students’ academic achievement and learning. This study examined whether there are interaction effects of a synergistic or compensatory nature. We applied the approach of integrative data analysis, using four highly powered data sets with a total of 18,637 upper secondary school students in Germany to investigate this research question across four different achievement measures and three educational domains (i.e., school subjects). We used an integrative approach and pooled the results across the four samples to obtain an average estimate of the hypothesized interaction effects. Findings support a small synergistic interaction, indicating that conscientiousness moderates the association between cognitive ability and achievement. This means conscientiousness can enhance the positive effects of cognitive ability. In conclusion, results highlight the role of the type of academic measure used and the domain investigated in understanding how personality and achievement are related, providing evidence of the interplay between effort-related traits such as conscientiousness and cognitive ability.

Direction of associations between personality traits and educational identity processes: Between- and within-person associations

INTRODUCTION

In adolescence, personality traits and educational identity processes are interwoven. Previous studies have shown that personality traits predict healthy identity commitment and exploration in education. However, the direction of associations between personality traits and an identity process that searches for another identity option (i.e., reconsideration of commitment) is unclear. Furthermore, there is a lack of prospective studies regarding the direction of the association between personality traits and the educational identity process using within-person methods. Therefore, this study examined the direction of these associations.

METHODS

Participants of this four-wave longitudinal study comprised 618 Japanese 13-year-old adolescents (53.3% girls). This study involved a 1-year-interval assessment.

RESULTS

Cross-lagged panel models (CLPM) indicated that four personality traits (neuroticism, agreeableness, and conscientiousness) predicted three educational identity processes, while reconsideration of commitment predicted two personality traits (i.e., neuroticism and conscientiousness). Random intercept cross-lagged panel models (RI-CLPM) indicated that agreeableness predicted healthy commitment, while commitment predicted agreeableness at within-person level.

CONCLUSION

The findings from CLPM suggest that reconsideration of commitment is a significant factor to predict healthy (i.e., conscientiousness) and unhealthy (i.e., neuroticism) personality traits in individual differences. Furthermore, the findings from RI-CLPM suggest that agreeableness may be a key trait in promoting healthy educational identity commitment. Theoretical and practical implications of these findings are discussed.

Fluid Intelligence and Competence Development in Secondary Schooling: No Evidence for a Moderating Role of Conscientiousness

Fluid intelligence and conscientiousness are important predictors of students’ academic performance and competence gains. Although their individual contributions have been widely acknowledged, less is known about their potential interplay. Do students profit disproportionately from being both smart and conscientious? We addressed this question using longitudinal data from two large student samples of the German National Educational Panel Study. In the first sample, we analyzed reading and mathematics competencies of 3778 fourth graders (Mage = 9.29, 51% female) and gains therein until grade 7. In the second sample, we analyzed the same competencies in 4942 seventh graders (Mage = 12.49, 49% female) and gains therein until grade 9. The results of (moderated) latent change score models supported fluid intelligence as the most consistent predictor of competence levels and gains, whereas conscientiousness predicted initial competence levels in mathematics and reading as well as gains in mathematics (but not reading) only in the older sample. There was no evidence for interaction effects between fluid intelligence and conscientiousness. We found only one statistically significant synergistic interaction in the older sample for gains in reading competence, which disappeared when including covariates. Although our findings point to largely independent effects of fluid intelligence and conscientiousness on competence gains, we delineate avenues for future research to illuminate their potential interplay.

Beyond Competencies: Associations between Personality and School Grades Are Largely Independent of Subject-Specific and General Cognitive Competencies

The Big Five personality traits are established predictors of school grades. However, the mechanisms underlying these associations are not yet well understood. Effects of personality on grades might arise because behavioral tendencies facilitate learning and increase subject-specific competencies. Alternatively, personality effects on grades might be independent of cognitive competencies and reflect otherwise valued behaviors or teachers’ grading practices. In the current study, we drew on large-scale data of 7th and 9th graders in Germany to explore the extent to which personality predicted grades even after accounting for competencies. Controlling for competencies and other key covariates, we cross-sectionally and longitudinally examined personality–grade associations across different school subjects, grade levels, and school types. Results indicate that the predictive power of personality is largely independent of subject-specific and general cognitive competencies. The largest effects emerged for conscientiousness. For openness, associations with grades partly overlapped with competencies, suggesting that openness may operate by fostering competencies. Overall, our results suggest that the associations between personality and grades unfold mostly independently of course mastery. This finding underlines the socioemotional value of personality in the classroom and encourages a more fine-grained view of the interplay between personality, competencies, classroom behavior, and grades.

The longitudinal interplay of personality and school experiences in adolescence

The school environment is one key developmental context that is assumed to shape individual characteristics during adolescence. However, little is known about which school experiences are central to personality change or whether school experiences and personality co-shape each other over time. We address this gap by examining the longitudinal interplay between seven school experiences in the three domains of achievement, social relationships, and well-being, and the Big Five personality traits at four measurement points from fifth to eighth grade. By using data from the German TRAIN study ( N = 3,473, MageT1 = 11.1 years, 45% female), we estimated bivariate latent growth curve models and cross-lagged panel models to illustrate this longitudinal interplay. Results demonstrated correlated change between school experiences and personality with differentiated patterns for achievement variables and a general longitudinal interplay with the social relationship and well-being variables. Furthermore, we found cross-lagged effects in both directions, although there were more effects of personality on school experiences. The most consistent predictor of school experiences was conscientiousness, whereas well-being in school in particular was related to personality change 1 year later. We integrate our findings into the current picture of personality development in adolescence and the role of school-related environmental factors.

Two Forms of Social Inequality in Students' Socio-Emotional Skills: Do the Levels of Big Five Personality Traits and Their Associations With Academic Achievement Depend on Parental Socioeconomic Status?

Some researchers and policymakers advocate a stronger focus on fostering socio-emotional skills in the hope of helping students to succeed academically, especially those who are socially disadvantaged. Others have cautioned that this might increase, rather than reduce, social inequality because personality traits conducive to achievement are themselves unevenly distributed in disfavor of socially disadvantaged students. Our paper contributes to this debate. Analyzing representative, large-scale data on 9,300 ninth graders from the German National Educational Panel Study (NEPS) and using the Big Five personality traits as a measure of socio-emotional skills, we cast light on two related yet distinct aspects of social inequality in socio-emotional skills: First, do levels of personality traits conducive to achievement vary as a function of students' parental socioeconomic status (pSES)? Second, do the returns to personality traits in terms of trait–achievement relations vary as function of pSES? Results showed that differences in Big Five traits between students with different pSES were small (0.04 ≤ |r| ≤ 0.09), especially when compared with pSES-related differences in cognitive skills (fluid intelligence) and sex-related differences in personality. The returns to Conscientiousness—the personality trait most relevant to achievement—in terms of its relations to academic achievement were higher in higher- vs. lower-SES students. Trait–achievement relations did not vary as a function of pSES for the other Big Five traits. Overall, both types of inequality were limited in magnitude. We discuss the implications of these findings for policy and practice and delineate directions for further research.

Personality and psychosocial functioning in early adolescence: Age-differential associations from the self- and parent perspective

Although psychosocial functioning and personality are indisputably interrelated in adulthood, much less is known about these associations in early adolescence. Accordingly, the goal of the current study was twofold. First, we investigated associations between adolescents’ personality and three broad indicators of psychosocial functioning: academic achievement, social relationships, and psychosocial adjustment. Second, we tested differential effects by comparing these associations across three different cohorts (Grades 5, 7, and 9) and across two raters of adolescents’ personality: self- and parent reports. Our sample consisted of N = 2667 students and their parents. According to latent regression models, adolescents’ personality traits showed significant associations with all psychosocial functioning variables: Achievement was most consistently associated with emotional stability, openness, and conscientiousness; social relationships were most consistently associated with agreeableness and conscientiousness; and psychosocial adjustment was related to all of the Big Five traits. Most associations did not vary across grades, whereas self-reported extraversion showed lower associations in later grades. Looking at rater-specific effects, we found fewer and usually smaller associations with parent- than with self-rated personality, again with the most significant differences with extraversion. We discuss the consistent interrelatedness between adolescents’ personality and psychosocial functioning but also highlight important exceptions in grade- and rater-specificities.
