This study examines the role of genes and environments in predicting educational outcomes. We test the Scarr-Rowe hypothesis, suggesting that enriched environments enable genetic potential to unfold, and the compensatory advantage hypothesis, proposing that low genetic endowments have less impact on education for children from high socioeconomic status (SES) families. We use a pre-registered design with Netherlands Twin Register data (426 ≤ N individuals ≤ 3875). We build polygenic indexes (PGIs) for cognitive and noncognitive skills to predict seven educational outcomes from childhood to adulthood across three designs (between-family, within-family, and trio) accounting for different confounding sources, totalling 42 analyses. Cognitive PGIs, noncognitive PGIs, and parental education positively predict educational outcomes. Providing partial support for the compensatory hypothesis, 39/42 PGI × SES interactions are negative, with 7 reaching statistical significance under Romano-Wolf and 3 under the more conservative Bonferroni multiple testing corrections (p-value < 0.007). In contrast, the Scarr-Rowe hypothesis lacks empirical support, with just 2 non-significant and 1 significant (not surviving Romano-Wolf) positive interactions. Overall, we emphasise the need for future replication studies in larger samples. Our findings demonstrate the value of merging social-stratification and behavioural-genetic theories to better understand the intricate interplay between genetic factors and social contexts. • Genes and family socio-economic status (SES) interact in predicting educational outcomes. • The Scarr-Rowe hypothesis states that high-SES families enable children to fully express their genetic potential. • The compensatory advantage hypothesis claims that low genetic endowments have less impact on education for high-SES children. • We build polygenic indexes for cognitive and noncognitive skills to predict seven outcomes across three research designs. • The Scarr-Rowe hypothesis lacks empirical support, while the compensatory advantage hypothesis is partially validated.

This article explores intergenerational class mobility patterns and the role played by education in Spain using counterfactuals. Both men and women born from 1926 to 1981 are analysed, meaning the study covers a period of profound economic and educational advances in a late-industrialised country. The results suggest that, among the cohorts born in the 1970s, men have experienced a slight increase in social fluidity, while women have experienced a substantial increase that seems partially driven by their massively increased access to routine non-manual positions independent of their social origins. Inequality of educational opportunities and class returns to education have declined, whereas the direct effect of social origins ( DESO ) has remained constant for men and has decreased considerably for women. The counterfactual analysis shows that the slight increase in social fluidity for men is mainly driven by educational expansion. For women, the DESO and educational expansion account for a great share of increasing fluidity. Therefore, certain assumptions made by the Modernization Theory and Goldthorpe ’ s Theory of Social Mobility can be put into question. [ABSTRACT FROM AUTHOR]

To assess the impact of digital media usage on psychiatric symptoms in an adolescent population utilizing a longitudinal cohort design. Using two waves of the GUI child cohort, age 13 (N = 7527) and age 17/18 (N = 6126), we used latent class analysis (LCA) to create latent groups centred around self-reported time spent online, and the self-reported behaviours children engaged with online. At both waves, the 4 class latent model suited best. We used the different symptoms scales of the Strengths and Difficulties Questionnaires (SDQ), self-reported, at age 17 as our outcome variable. Using linear regression analysis, we then examined the associations between our latent class model and psychiatric symptoms, using moderate usage as our reference group, with adjustments being made for baseline psychiatric symptoms, maternal education and pre-diagnosed mental disorder. For females, placement in the high usage group at 13 was associated with increased internalizing symptoms, whereas placement in the high usage group at 17 was associated with an increase in all symptoms. For males, placement in the high usage group at 17 was associated with increased emotional symptoms, and placement in the "low usage & behaviour engagement"group, a group showing low reported time online and low engagement in our measured online behaviours at 17, was associated with an increase in all symptoms. Finally for both sexes, placement in the "moderate usage, entertainment only" group at age 13, (a group reporting no school-based online engagement), was associated with increases in all symptoms except emotional symptoms. High digital media usage is associated with increased psychiatric symptoms in both males and females, with moderate usage associated with positive effects on symptoms compared to both our high usage, and low usage groups. • Using latent class modelling, this paper attempted to combine both time based and behavioural based digital meida useage into a single exposure and examine its associations with psychiatric symptoms. • Longitudnal assocations between age 13 digital media engagment and age 17 psychiatric symtoms show, for females, increased internalizing symptoms if placed in the "high usage" group, and for both genders, increases in widespread symptoms if placed in the "exclude education" group, a group indicitave of no behavioural engagament with education materials online. • Cross Sectionally, while adjusting for multiple confounders including age 13 usage and age 9 psychiatric symptoms, we found that placement in the "high usage" group was associated with widespread symptoms increases for females and internalizing symptom increases for males. Additionally, placment in the "low time and behaviour" group, was asociated with widespread symptom increases for males only. [ABSTRACT FROM AUTHOR]
