Given that camouflaging has been suggested to contribute to delayed diagnosis and mental health problems among autistic people, validated measures of the construct are needed. This study describes the psychometric evaluation of the Swedish adaptation of the self-reported Camouflaging Autistic Traits Questionnaire (CAT-Q) in autistic (n = 100) and…

This study aimed to understand how mindfulness meditation affects young people by examining its impact on self-regulation, happiness, emotional awareness, and school performance among two groups of school children. A 10-week mindfulness program was conducted by a meditation expert for 552 children aged 4-8 (Group 1) and 287 children aged 9-11…

This 1-year longitudinal study examined the association between student-teacher relationship quality and school liking in a sample of 234 students from two public schools in Sweden, who completed an online questionnaire on two separate occasions. The age range was 9-15 years in Time 1 and 10-16 years in Time 2. A path analysis showed that students…

This study was conducted to determine how total fundamental movement skill (FMS) score and, separately, locomotor skill (LMS), and object control skill scores in children 3-8 years old predicted their specific-intensity physical activity 3 years later. Overall, 441 Finnish children (51.7% female, baseline mean age of 5.6 years) participated in the…

Handwriting is a useful skill through education, yet handwriting difficulties are common in students with Specific Learning Difficulties (SpLD), including Developmental Coordination Disorder. There are few practical tools to assess legibility, among these the Handwriting Legibility Scale (HLS) shows good reliability and validity for 9- to…

The purpose of this study was to examine the factorial invariance of the ASIS (Anadolu Sak Intelligence Scale) across gender. Raw scores from the ASIS standardization study (N = 4641) were used in the analyses. Factorial invariance was analyzed by gender across three age groups: 4-7 (N = 2528), 8-9 (N = 848), and 10-12 (N = 1265) using the…

Using a sample of healthy youth (n = 466, 10 to 18 yr), we report the predictive utility of vertical jump power (VJ Power, W) for predicting bone strength. We measured VJ Power using mechanography and an indicator of bone strength, i.e., height-adjusted total bone mineral content less head (TBLH BMC, g), using DXA. Growth curve models were used to…

We examined Canadian host-society children's prosociality (i.e., emotions and behaviors that reflect care for the welfare of others) toward refugee newcomer peers and the role of parental socialization (i.e., frequency of parent-child conversations about refugee newcomers) in children's refugee-specific prosociality. The sample included 168…

The present research aimed to identify and compare playfulness levels of individuals aged 10-14 years engaging in individual and team sports. The sample consisted of 356 participants. We employed a correlational design and used the "Playfulness Scale for 10-14-years-old Children" developed by Hazar as the data collection tool. In data…

Background: Developmental research provides considerable evidence of a strong relationship between verbal and visuospatial working memory (WM) and mathematics ability across age groups. However, little is known about how components of WM (i.e., short-term storage, processing speed, the central executive) might relate to mathematics sub-categories…

The present study examined younger and older children's perceptions of friendship characteristics and expectations from best friends. One hundred and eighty eight children (Mage = 8.51 years old, SD = 1.70, age range: 6-11 years old) from two primary schools of Athens were involved in a 15-min semi-structured interview and produced drawings of…

Our interest is in the development of gratitude as a moral virtue, and its variability across different cultural contexts. Given psychology's overreliance on samples collected from the United Sates, Western Europe, and Australasia, we contrasted patterns of age-related expressions of gratitude among a sample of U.S. 7- to 14-year-old children with…

Background: Fundamental Motor Skills (FMS) are important building blocks for children's sport-participation and lifelong physical activity. In the last decade, several international studies have reported delays in the development of FMS. To get better insight into the Dutch situation and to provide future directions, this study examined the…

Our ability to perceive our own and other people's bodies is critical to the success of social interactions. Research has shown that adults have a distorted perception of their own body and those of other adults. However, these studies ask perceivers to estimate for adults with a similar bodily make-up. This study explored the developmental…

This article discusses findings from the first 10 years of the Longitudinal Outcomes of Children with Hearing Impairment (LOCHI) Study, which includes more than 450 deaf and hard of hearing Australian children whose hearing losses were identified variously through newborn hearing screening or later paths to confirmation and intervention.
