This study examined the new self-report version of the Strengths and Difficulties Questionnaire (SDQ-S), SDQ-Kids, in primary school children regarding internal consistency, teacher-child agreement, and validity. Data from 2,655 children in Grades 1 to 3 and their teachers were analyzed. Children completed SDQ-Kids, previously piloted (n = 896),…

Scholars have long argued that individuals' beliefs influence their behaviors and the decisions they make throughout their lives. Focusing on beliefs as a cognitive construct, the purpose of this study was to identify several key beliefs about mathematics teaching and learning held by practicing elementary mathematics teachers. An iterative…

Research has consistently shown that difficulties in facial emotion recognition (FER) are associated with peer problems and internalizing symptoms during middle childhood. However, no longitudinal research has investigated the direction of effects, that is, how these constructs influence each other across time. In this preregistered three-wave…

Whether and to what extent kindergarten children's executive functions (EF) constitute promising targets of early intervention is currently unclear. This study examined whether kindergarten children's EF predicted their second-grade academic achievement and behavior. This was done using (a) a longitudinal and nationally representative sample (N =…

This study examined the impact of a commonly adopted elementary universal social-emotional learning program, Second Step, on student social-emotional and academic outcomes following 2 years of implementation. The cluster-randomized wait-list control trial included 61 schools, 321 teachers, and 8,941 early elementary students across 2 states, with…

Gender is a critical social factor influencing how children view the world from very early childhood. Additionally, during the early elementary years, parents can have a significant influence on their child's behaviors and dispositions in fields such as science. This study examined the influence of parent gender and child gender on 2nd- and…

This study used a multiple probe across participants design, replicated across two interventions and counterbalanced across participant groups to examine the effects of number sense intervention and extensive practice intervention on strategy transformation when students with mathematics learning disabilities (MLD) solved basic fact problems. In…

Research has established that long-term exposure to peer victimization is associated with higher levels of emotional and behavioral maladjustment. Yet, relatively little is known regarding predictors of stable versus declining victimization across extended periods of time. To fill this knowledge gap, the present study used latent growth curve…

The purpose of this paper is to describe the implementation of an evidence-based treatment, the Incredible Years® (IY) Small Group Dina Dinosaur Treatment program, as delivered in elementary schools to address the needs of children in kindergarten through second grade with self-regulation difficulties. Adaptations for school-based delivery of 17…

So far, empirical evidence regarding the effects of extended education on externalizing behavior is mixed. To explore possible moderators, multilevel-analyses were conducted in a longitudinal sample of 492 students from 51 all-day schools in Switzerland. No main effects of utilization intensity, interaction quality and externalizing behavior in…

This study reports the results of a randomized controlled trial examining the effect of Conjoint Behavioral Consultation (CBC), a family-school partnership intervention, on children's behaviors, parents' skills, and parent-teacher relationships in rural community and town settings. Participants were 267 children, 267 parents, and 152 teachers in…

There is growing consensus among researchers and practitioners that children's socialemotional readiness makes unique contributions to their successful transition to and progress through school. However, many children still begin school ill-prepared for the behavioral demands they will encounter in the classroom. This study examines the joint…

This longitudinal study, conducted among a sample of Finnish primary-school children, examined the proposition that a single high-quality relationship (either with a teacher or a parent) can buffer against adjustment problems. Teachers rated the externalizing problems and prosocial behaviors of 378 children in Grade 1 and again in Grade 2.…
