Daily living skills may affect repetitive behavior patterns in individuals with autism spectrum disorder (ASD). This study aimed to validate a scale to assess activities of daily living at home (SAADL) in children and adolescents with ASD. Content validity by expert judgment showed Aiken V values between 0.75 and 0.88. The exploratory factor analysis (EFA) showed factor loadings (0.62 to 0.89) and high communalities. The % explanation of variance for dimension 1 (personal care) was 51.5% and for dimension 2 (mobility in the home) was 66.3%. The Cronbach's reliability was 0.87 and the retest values reflected high values of precision and accuracy. The SAADL is valid and reliable and can be used to assess activities of daily living of self-care and mobility at home.

The aim of this study was to compare bibliometric indicators of scientific productivity in physical activity (PA) in children and adolescents with Autism spectrum disorder (ASD) and Down syndrome (DS) in the PubMed database. A bibliometric study was conducted for the last 5 years (2017 to 2021). The data collected for each article were: year of publication, language of publication, country, journal name, and type of paper. The results showed that there was higher scientific productivity in the population with DS (20 studies) relative to their counterparts with ASD (31 studies). The language of publication in both cases was English. There were 10 countries that published on PA in ASD and 14 countries that published on DS. Overall, the greatest interest in publishing on PA in children and adolescents with ASD was in North America (6 studies), followed by Asia (5 studies) and Europe (4 studies). In the DS population it was in Europe (13 studies), North America (9 studies) and South America (4 studies). Nineteen journals were identified that published in the ASD population and 29 journals in DS. Six experimental studies were identified in ASD and 7 in DS. There was a higher scientific productivity with original studies. There was a positive trend of increasing scientific productivity over the years in both populations. We suggest the need to promote research on PA in both populations, regardless of the type of study, as it is an indicator of overall health status.

The objectives of this study were to characterize the bibliometric indicators of scientific productivity on adaptive behavior (AB) in children and adolescents with autism spectrum disorders (ASD) during the year 2021. The PubMed database was used to summarize information from quantitative scientific articles (cross-sectional, longitudinal and experimental) and reviews (bibliographic, systematic review and meta-analysis). The data collected for each of the articles were: year of publication, journal name, country, language of publication and type of published document (cross-sectional study, longitudinal, experimental, biographical review, systematic review and meta-analysis). The United States (USA) published more articles than any other country in the world (n = 28), followed by Italy with 13 studies, China and Spain with six studies. A total of 44 scientific journals were identified that have published a total of 89 scientific articles related to AB in children and adolescents with ASD. Regarding the type of published paper, 63 quantitative studies were identified (cross-sectional studies, 9 longitudinal studies, 15 experimental studies). In addition, 14 literature reviews, 9 systematic reviews, and 3 systematic reviews/meta-analyses were identified. These results suggest practitioners and researchers to address and decide where to read and publish scientific articles related to AB in youth with ASD.

The development of social skills (SS) at various stages of life provides the basis for social and academic success throughout life. This cross-sectional study validates and verifies the reliability of the SS checklist proposed by Goldstein et al 1983. The checklist was administered, which is composed of 6 dimensions and 50 SS questions. 671 students between 18 and 25 years of age, belonging to eight professional programs in the area of Educational Sciences, participated. The results showed that five factors explained 41.4% of the variance of the instrument. The Kaiser-Meyer-Olkin KMO measure of 0.906 and Bartlett's test of sphericity were highly significant (X[superscript 2]= 11020.251, gl= 1225). The factor loadings of the 6 dimensions and the 50 questions ranged between 0.42 and 0.72. The reliability achieved by Cronbach's alpha was r=0.92. The proposal of percentiles will allow classifying low, moderate and high levels of SS, providing information that can be used not only by students, but also for professionals working in higher education. Consequently, it highlights the importance of developing SS not only at home, but also at school and university, since they need to be stimulated at every stage of life to achieve the proposed objectives.

The aim of the study was to validate an instrument and propose standards to measure the language skills of school adolescents. 2270 adolescents (1134 males and 1136 females) in the region of Maule (Chile) was studied. The age range is between 10 to 18 years. The validated instrument has three categories (verbal, paralinguistic and non-verbal) and a total of 26 items. The instrument showed to be valid after the exploratory analysis and Cronbach [alpha] (0.86 to 0.88) showed highly reliable values. The LMS method to develop percentiles, let p10, p50 and p90 calculated by age and sex. The instrument measures developed language skills valid and reliable also adopted cutoffs allow diagnose and adolescents by age and sex. These results suggest the use and application of the instrument as an everyday tool in social, cultural and educational contexts.

The objectives of this study were to (a) verify the validity and reliability of a scale to assess skill levels to learn content knowledge (SLACK) and (b) develop percentile norms to assess the SLACK of adolescent students. The study included 2270 students (1134 males and 1136 females) ranging in age from 10.0 to 18.9 years old. A scale was used to measure the SLACK. The results showed high values of validity (saturation between 0.32 and 0.54) and with internal consistency from 0.83 and 0.84. The LMS method made it possible to create percentiles p10, p50, and p90 in order to classify the (SLACK) based on category, age, and sex. The results suggested the use and application of the scale with the school education system by using the percentiles to diagnosis, classify, and monitor the skills for learning knowledge validly and reliably.

Currently, the lack of physical activity can lead to health problems, with the increase in obesity in children between 8 and 18 years old being of particular interest because it is a formative stage. One of the aspects of trying to solve this problem is the need for a standardized, less subjective, and more efficient method of evaluating physical condition in these children compared to traditional approaches. Objective: Develop a multiplatform based on computer vision technology that allows the evaluation of the physical fitness of schoolchildren using smartphones. Methodology: A descriptive cross-sectional study was carried out on schoolchildren aged 8 to 18 years of both sexes. The sample was 228 schoolchildren (128 boys and 108 girls). Anthropometric measurements of weight, height, and waist circumference were evaluated. Body mass index (BMI) was calculated. Four physical tests were evaluated: flexibility (sit and reach), horizontal jump (explosive strength), biceps curl (right arm strength resistance), and sit-ups (abdominal muscle resistance). With the information collected traditionally and by filming the physical tests, a computer vision system was developed to evaluate physical fitness in schoolchildren. Results: The implemented system obtained an acceptable level of precision, reaching 94% precision in field evaluations and a percentage greater than 95% in laboratory evaluations for testing. The developed mobile application also obtained a high accuracy percentage, greater than 95% in two tests and close to 85% in the remaining two. Finally, the Systematic Software Quality Model was used to determine user satisfaction with the presented prototype. Regarding usability, a satisfaction level of 97% and a reliability level of 100% was obtained. Conclusion: Compared to traditional evaluation and computer vision, the proposal was satisfactorily validated. These results were obtained using the Expanded Systematic Software Quality Model, which reached an "advanced" quality level, satisfying functionality, usability, and reliability characteristics. This advance demonstrates that the integration of computer vision is feasible, highly effective in the educational context, and applicable in the evaluations of physical education classes.

Objective: a) to verify whether body composition and physical fitness should be analyzed by chronological age and/or maturity stage in young Brazilian soccer players and b) to propose reference values for the evaluation of body composition and physical fitness by maturity stage in elite soccer players. Methods: A descriptive-correlational study was carried out in 206 young Brazilian soccer players (11-16 years old). The sample selection was non-probabilistic by convenience. Weight and standing height were evaluated. Body composition (BC) was assessed by dual X-ray absorptiometry (DXA). BC indicators [(percent fat (%F), Fat-free mass (FFM), Fat mass (FM) and Bone mass (BM)] were extracted. For physical fitness (PF), we applied the Flexibility (cm) sit and reach tests, explosive strength tests [Counter Movement Jump CMJ (cm) and horizontal jump HJ (cm)], speed [Speed 10, 20, 30 and 40m (seconds)] and Yo-Yo endurance level I test. Percentiles were constructed for BC and PF using the LMS method [L (Lambda; skewness), M (Mu; median) and S (Sigma; coefficient of variation)]. Results: The explanatory power between chronological age (CA) with BC was: FM (R2 = 0.03%), FFM (R2 = 0.66%) and BM (R2 = 0.62%), while between maturity status (MS) with BC were: FM (R2 = 0.04%), FFM (R2 = 0.71%) and BM (R2 = 0.66). The explanatory power between the CA with the physical fitness tests ranged from: (R2 = 0.22-0.62%). While between MS with physical fitness the values ranged from: (R2 = 0.23-0.64%). Percentiles per MS (P3, P5, P10, P15, P25, P50, P75, P85, P90, P95 and P97) were proposed for both BC and PF. Conclusion: The results of the study have shown that the evaluation of BC and PF of young soccer players should be performed by controlling for MS rather than for CA. The inclusion of a non-invasive method to control MS by means of percentiles during puberty may contribute to the development of retention and exclusion of young soccer players, thus, they may have a better chance of achieving sporting success.
