Researchers are often inclined to test agreement or discrepancy hypotheses using difference scores. This commentary explains 2 mathematical-statistical principles underlying associations with difference scores and 2 conceptual-interpretation problems that make difference scores inappropriate for testing such hypotheses. The commentary provides…

The use of differences scores to assess agreement/disagreement has a long and contentious history. Laird (2020) notes, however, that developmentalists have been particularly resistant to discontinue the use of difference scores. One area of developmental science where difference scores are still in regular use is that of parental differential…

Change-point analysis (CPA) is a method for detecting abrupt changes in parameter(s) underlying a sequence of random variables. It has been applied to detect examinees' aberrant test-taking behavior by identifying abrupt test performance change. Previous studies utilized maximum likelihood estimations of ability parameters, focusing on detecting…

For students exhibiting challenging behaviors that are nondangerous to others and nondisruptive to classroom activities, such as daydreaming and doodling, educators are unlikely to refer these students for more individualized and resource-intensive behavioral support. As a step towards understanding how to address these students' motivational…

When results of descriptive functional behavior assessments (FBAs) are inconclusive, experimental analysis methods can be used to directly test hypotheses about when or why a student engages in challenging behavior. Despite growing research on practical variations of hypothesis testing in schools, these methods are rarely incorporated in FBAs in…

There is an urgent need to aid in what will be an ongoing educational recovery in the wake of the COVID-19 pandemic. One avenue for supporting students with and at-risk for emotional and behavioral disorders (e.g., internalizing and externalizing behaviors) is implementation of tiered systems, which emphasize evidence-based practices to prevent…

As part of standards-based reforms, there is increasing emphasis on ensuring that students with moderate intellectual disabilities (ID), including students with Autism Spectrum Disorders (ASD), learn to read. There is also converging evidence that explicit teaching of letter sounds, phonics, and sight words is effective for this population, but…

Despite the early onset of challenging behaviors, there is a lack of research investigating the function of challenging behavior in toddlers with autism spectrum disorder (ASD) and developmental disabilities (DDs). The current study evaluated group differences in the frequency and severity of five functions of challenging behavior (i.e.,…

The use of standardized assessment in evidence-based practice (EBP) is critical in identifying empirically supported interventions (ESIs); however, the subject has received minimal attention in the literature. In a sample of child welfare involved youth, this study sought to determine whether there was a relationship between dimensions of trauma…

There is a paucity of research in Australia about educators' use of differentiated instruction (DI) to support the learning of students with ADHD. This study reports on a small-scale, qualitative research using interviews with teachers and school leaders to identify how they use DI as an effective teaching instruction for students with ADHD.…

Objective: Children with ADHD often experience functional impairments across various aspects of daily life. This study addresses the dearth of longitudinal research on functional impairment trajectories from preschool to school age in children with symptoms of ADHD and comorbid disorders. Methods: We investigated the extent to which functional…

Background: Personal characteristics of troubled adolescents are affected by psychological deprivation, which contributes to the manifestation of deviant and delinquent behavior in individuals. Aim: This study comprehensively examines structural units of self-consciousness, higher mental functions, and the emotional sphere of troubled adolescents…

Considerable studies have shown the protective effects of breastfeeding on internalizing problem behaviours in early childhood, yet little is known about the groundwork for this relationship. This study attempted to test the hypothesis that improvement of mothers' positive parenting behaviours by breastfeeding can explain the relationship. We used…

Emerging evidence suggests interventions can improve childhood self-regulation. One intervention approach that has shown promise is Taekwondo martial arts instruction, though little is known about its acceptability among stakeholders or its mechanisms of effect. We extend evidence on Taekwondo interventions in three ways: (1) testing the efficacy…

Recent research findings (DeRosa, Fisher, & Steege, 2015) suggest that minimizing exposure to the establishing operation (EO) for destructive behavior when differential reinforcement interventions like functional communication training (FCT) are introduced may produce more immediate reductions in destructive behavior and prevent or mitigate…
