Intelligence (IQ) scores are used in educational and vocational planning for individuals with autism spectrum disorder (ASD) yet little is known about the stability of IQ throughout development. We examined longitudinal age-related IQ stability in 119 individuals with ASD (3-36 years of age at first visit) and 128 typically developing controls.…

Feeling inhibited and socially not at ease is reflected in the trait social inhibition (SI). SI is associated with psychopathology that arises in young adulthood, such as anxiety. We aim for a better insight into the genetic and environmental contributions to SI across the life span, and as such examine their contributions to SI stability and…

In the Early Childhood Education and Care (ECEC) sector there is a move to reduce oversight costs by reducing the frequency of quality assessments in providers who score highly consistently across time. However, virtually nothing is known about the stability of ECEC quality assessments over time. Using a validated measure of overall classroom…

Special education teacher attrition is a significant and chronic problem that has worsened since the pandemic. A longitudinal survey of burnout was conducted with rural special education teachers (n = 48) over four timepoints through the school year just prior to COVID-19. Both school and intrapersonal predictors of burnout obtained at the…

Despite the importance of self-control for well-being and adjustment, its development from early childhood to early adolescence has been relatively understudied. We addressed the development of mother-reported self-control in what is likely the largest and longest longitudinal twin study of the topic to this day (N = 1889 individual children with…

Purpose: The evidence is strong that the instability of teacher rosters in urban school settings has negative consequences for student learning, but our concern is with the opposite phenomenon--What is the value added to the organization when a school's teaching roster is stable over time? Our theory of teacher corps stability hinges on the claim…

I employ a year and country-level fixed-effects analytical technique to examine how private schooling could impact national stability using five different measures. I examine 177 different countries across the globe from 1999 to 2014. Most importantly, this technique allows me to conduct a quasi-experimental analysis by controlling for otherwise…

Thailand 4.0 is an ambitious reform strategy that seeks to offset the impact of the Thai aging population by transitioning the economy towards a knowledge-based society skilled in advanced technology. Education reforms are paramount for Thailand 4.0 to succeed; however, significant challenges exist that draw into question the capabilities and…

This study examined longitudinal associations between early adolescents' school friendship stability, instability, and network size and their perceived social adjustment. The final sample consisted of 430 early adolescents residing in seven Midwestern schools (52% female, 47% Black, 42% White, 5% Hispanic or Latinx, and 6% Other). School…

Research Findings: This study employed multiple approaches to examine the stability of teacher--child interaction quality in Chinese preschools. Teacher-child interaction quality was measured using the "Classroom Assessment Scoring System" (CLASS) on five observational cycles within a school day. Several different metrics of stability…

The purpose of this study is to evaluate how learning disabilities (LDs), in combination with accommodations, affect the performance of a decision-tree to predict the stability of academic behaviour of undergraduate engineering students. Additionally, this study presents several examples to illustrate how a college could use the resultant model to…

Purpose: Recent attempts to measure schools' influence on students' social-emotional learning (SEL) show differences across schools, but whether these estimated differences measure the true effects of schools remain unclear. To better understand these measures, we examine the stability of estimated school-by-grade effects across 2 years using…

This study examined the development of caregiver mind-mindedness--defined as the propensity to see one's child as an agent with an independent mind--across the first 1,000 days of life. At four timepoints (i.e., third trimester of pregnancy, 4, 14, and 24 months postpartum), 384 first-time mothers (M[subscript age] = 32.55, SD = 3.63 years) and…

The current study investigated the stability of children's risk status across the preschool year. A total of 1,102 preschool children attending Title 1 schools (n = 631) and non-Title 1 schools (n = 471) participated in this study. Using averaged standard scores for two measures of language, print knowledge, and phonological awareness administered…
