This work refined the complex associations between aggression (aggressive behavior and victimization) and school functioning in terms of school liking, interest, achievement, and social class climate. First, using longitudinal multilevel structural equation modeling, it was shown that aggressive behavior and victimization preceded lower school…

Although COVID-19 is being disruptive to all children, the effects are stronger for children with disabilities. Therefore, the aim of this study was to analyse, from a holistic perspective, the well-being of children with special needs during the total lockdown period in Spain. The 'Well-being of Children in Lockdown' (WCL) scale was completed by…

Learning Together is a whole-school intervention, evaluated using a randomized controlled trial in southeast England, which reduced bullying and improved physical and mental health. This paper examines trial data using fuzzy-set qualitative comparative analysis to test hypotheses derived from embedded qualitative research about potential causal…

This group-randomized trial assessed the effects of a universal prevention training curriculum for school administrators and teachers that focused on effective strategies to prevent adolescent substance use and related problems. Twenty-eight schools in three regions of Peru were randomly assigned to either an intervention or control condition (14…

The current study aims to investigate factors affecting the online learning anxiety of preadolescent learners during COVID-19 prevention policy. The study was designed with a survey approach. The participants were 181 grade 6 students in a public school in Thailand selected by Yamane's sampling method. During the data collection, Thai educational…

This study explores relationships between Taiwanese Sign Language (TSL) and Chinese reading comprehension with 65 deaf adults/youth (study 1: ages 14--50 years) and 27 deaf children (study 2: ages 6--13 years). Significant relationships were found between scores on two tests measuring TSL tasks. In study #1, the TSL tasks (measured by Taiwan Sign…

This study examined the predictive validity of musculoskeletal fitness tests for identifying sarcopenia in youth. The sample was 529 participants age 10 to 18 years. Indices included: total lean body mass (LBM) normalized for height (LBM index, LBMI, kg/m2), appendicular LBMI (aLBMI, kg/m[superscript 2]), and LBM to fat body mass (FBM) ratio…

Background: Increased parental stress is strongly related to the severity of autism spectrum disorder (ASD) symptomatology. Parents' coping strategies and social support issues add to the complexity of this relationship. Aim: The present study investigated the relationship between self-regulation skills and parenting stress in parents of nonverbal…

Atypical sensory processing is prevalent across neurodevelopmental conditions and a key diagnostic criterion of autism spectrum disorder. It may have cascading effects on the development of adaptive functions. However, its unique contribution to adaptive functioning and the genetic/environmental influences on this link are unclear. In a clinically…

In today's society, values are already an important part of any social and educational project. Physical activity and sport are excellent instruments to promote the conveyance of values resulting in personal and social development. However, an increasing number of authors state that the mere practice of physical activity in itself does not develop…

Purpose: This study measured between-groups differences in perceived speech skills and personality characteristics of a 12-year-old male child who stutters (CWS) as a function of a written factual stuttering disclosure statement, delivered by the CWS, his "mother," or his "teacher." Method: Four hundred twenty-four college-age…

Choosing the right strategy is an important condition to successfully solve math problems. Research studies often present individual types of strategies more or less separately. This study aims to determine student solutions of selected word problems in the whole context of the solution process. In this context, such nonstandard word problems…

The article focuses on the contentious relation between cyberbullying and physical, verbal, and relational bullying. Drawing on items from the Olweus questionnaire, the study used confirmatory factor analysis and structural equation modelling, and latent factors of bullying were fitted to the data. Different background variables were related to…

Research has uncovered a semantic cue effect for short inconsistent word problems; the presence of functionally related objects makes them easier for pupils than the presence of categorically related ones. This study builds on this result by investigating other types of problems. Variants of problems differing in a semantic cue were solved by…

An emerging body of research suggests that temporal processing may be disrupted in autistic children, although little is known about behaviours relating to time in daily life. In the present study, 113 parents of autistic and 201 parents of neurotypical children (aged 7-12 years) completed the "It's About Time" questionnaire and…
