Personality variables are associated with educational attainment and socioeconomic outcomes. In this study we incorporated a polygenic score derived from the largest genome-wide association study (GWAS) of educational attainment to date (Lee et al., 2018) into the Interactionist Model of R. D. Conger, Martin, and Masarik (2021) that describes the influence of socioeconomic factors on individual development. The inclusion of a polygenic score predictive of educational attainment (PS-Edu) into this model, and the use of the multigeneration, longitudinal Family Transitions Project (FTP) provide a unique opportunity to investigate genetic and environmental influences on the development of negative personality traits and educational and economic outcomes. The FTP is a three-generation sample. This study utilized data from the first generation (G1; mean age 40 at initiation of the FTP) and second generation (G2; assessed at mean ages 18 and 30). Participants are approximately 50% female, 99% of European ancestry, primarily from lower to middle class SES. 2-Deoxy-D-glucose molecular weight PS-Edu was significantly correlated with educational attainment in both generations of the FTP, accounting for 4.1 to 6.7% of the variance. Findings confirm that PS-Edu is a complex genetic index that is correlated with all of the socioeconomic constructs in the model. Results suggest potential gene-environment correlation or common genetic influences underlie associations among parenting investments, negative personality traits, and educational attainment. Genetic variance captured by PS-Edu was mediated substantially through G1 parental investments. Although study limitations warrant cautious interpretation, we demonstrate the promise of including polygenic scores in developmental models to better understand genetic and environmental influences on human development.

The challenge is to find ways to incorporate genetic information based on studies using biologically related family members (i.e., studies not involving twins). To address this issue, we computed polygenic scores associated with educational attainment (Lee et al., 2018) for the Family Transitions Project (e.g., R. D. Conger & Conger, 2002) and incorporated them into the model tested by R. D. Conger, Martin, and Masarik, (2021). Polygenic scores correlated with observed educational attainment for all relevant members of the Family Transitions Project. Moreover, polygenic scores were correlated with many of the other constructs in the R. D. Conger et al. (2021) model, pointing to the relevance of genetic factors for process models of SES attainment. At the same time, the primary pathways described by R. D. Conger et al. (2021) remained viable when polygenic scores were included in the analyses, suggesting that the environmental pathways predicted by the interactionist model (e.g., R. D. Conger, Conger, & Martin, 2010) are still tenable. The current study thereby illustrates how genetic information can be included in tests of developmental models to clarify SES attainment across generations.

The model tested proposed that lower family socioeconomic status would lead to fewer parenting and material investments in the next generation adolescent, which in turn would be associated with higher levels of adolescent negative personality traits. The IM also predicted a transactional process in which adolescent negative personality attributes would then deter future socioeconomic success during adulthood which, in turn, would hinder adult development in terms of greater feelings of alienation and diminished well-being. Analyses with a cohort of 347 adolescents followed for over 20 years produced findings consistent with these predictions. Moreover, additional analyses with 282 of the third generation children of these cohort members demonstrated that this same process was being replicated in the third generation. The findings suggest reciprocal or transactional influences that promote the development of negative personality attributes and accumulating personal, economic and social advantages over time and generations.

In an approach consistent with the idea of cumulative advantage, the model proposed that adolescent and child conscientiousness would be fostered by higher family socioeconomic status (SES) and the parenting and material investments that SES promotes. The IM also predicted a transactional process in which adolescent conscientiousness would promote future socioeconomic success which, in turn, would foster greater adult conscientiousness. Analyses with a cohort of 347 adolescents followed for over 20 years were largely consistent with these predictions, although the findings suggested some modifications to the IM, including the addition of a stronger direct role for family processes in eventual social and economic outcomes. Moreover, additional analyses with 282 of the children of these cohort members demonstrated that this same process was partially replicated in the next generation of children. The findings suggest reciprocal or transactional influences that promote conscientiousness and accumulating personal, economic, and social advantages over time and generations. (PsycInfo Database Record (c) 2021 APA, all rights reserved).This special section focuses on the life-course development of positive and negative personality traits and their consequences. Specifically, we pose four research questions inspired by the special section in Developmental Psychology on Conscientiousness (Reiss, Eccles, & Nielsen, 2014). The current set of articles extends the examination of the positive effects of Conscientiousness on individual well-being by also considering the potentially disruptive effects of specific negative personality traits (alienation and low sense of well-being). Our four questions are as follows. Question 1 what are the correlates of Conscientiousness and negative personality traits in terms of family processes? Question 2 to what degree do Conscientiousness and negative traits operate in a transactional process with the social and economic environment to amplify or suppress these characteristics? Question 3 how do individual personality characteristics affect specific behaviors and interactions within lived-environments to impact later well-being and life outcomes? Question 4 is there evidence that particular genetic characteristics affect connections between personality and its antecedents or consequences? One unique aspect of the present special section is that we address these issues across time utilizing prospective, longitudinal data provided by over 2,400 individual family members participating in the Family Transitions Project (FTP).
