BackgroundThe quantity and quality of studies in child and adolescent physical activity and sedentary behaviour have rapidly increased, but research directions are often pursued in a reactive and uncoordinated manner.AimTo arrive at an international consensus on research priorities in the area of child and adolescent physical activity and sedentary behaviour.MethodsTwo independent panels, each consisting of 12 experts, undertook three rounds of a Delphi methodology. The Delphi methodology required experts to anonymously answer questions put forward by the researchers with feedback provided between each round.ResultsThe primary outcome of the study was a ranked set of 29 research priorities that aimed to be applicable for the next 10 years. The top three ranked priorities were: developing effective and sustainable interventions to increase children’s physical activity long-term; policy and/or environmental change and their influence on children’s physical activity and sedentary behaviour; and prospective, longitudinal studies of the independent effects of physical activity and sedentary behaviour on health.ConclusionsThese research priorities can help to guide decisions on future research directions.

Until now, there has been no integrated study of the cognitive, motor and academic developments in children in the Arab world. In this study we investigated gender differences in those three areas in primary school-aged children in Oman and as well as the inter-relations between those three aspects of development. Ninety-five third graders completed four working memory tests, a mental rotation test and a motor test. Furthermore, the marks in math, science and Arabic language were registered. The result showed that there were small gender differences: Girls performed better in one of the working memory tests and boys in the coordination motor test. The study also showed that there were significant correlations between cognitive variables and academic performance, as well as two significant correlations between motor performance and marks in math and science. Marks in math correlated with the performances in the 20 m run and the coordination test, whereas the marks in science correlated with the ball-leg-wall test, the coordination test, and the endurance test. Regression analysis showed that all marks were predicted by the working memory and mental rotation performance as well as the motor ability. This means that academic achievement in Oman could be predicted by basic cognitive as well as motor abilities.

Background The aim of this study is to validate the Arabic version of the Basic Psychological Need Satisfaction and Frustration Scale (BPNSFS), and to investigate the extent of its invariance across five Arab countries and gender. Methods A back-translated version of the BPNSFS, the second version of the Beck Depression Inventory (BDI-II), and the Warwick-Edinburgh Mental Well-Being Scale (WEMWBS) were administered to a sample consisting of 1082 undergraduate students affiliated with universities in five Arab countries (487 males and 595 females: Mage = 20.04 ± 1.87 years). The data of the BPNSFS were examined for univariate and multivariate normality using Shapiro–Wilk tests and Mardia’s coefficient, respectively. To evaluate and compare the four models with confirmatory factor analysis (CFA), we used the following goodness-of-fit indices: the chi-square value (χ2), comparative fit index (CFI), Tucker-Lewis index (TLI), Root Mean-Square Error of Approximation (RMSEA), and Baysian Information Criterion (BIC). A multi-group CFA [Byrne in Structural equation modeling with EQS: basic concepts, applications, and programming, Routledge, Abingdon, 2013] on the BPNSFS structure to examine its invariance across the five Arab countries and across genders. Results The results of confirmatory factor analysis supported the generalizability of the BPNSFS’s six-factor model to the five Arab countries. The relationships between the six psychological needs satisfaction and frustrations and both mental health and symptoms of depression provide additional evidence on the construct validity of the BPNSFS through cross cultural data. The findings of BPNSFS’s measurement invariance across males and females and across the five Arab countries help ensure that the latent means are comparable across these different groups. Conclusions The study concluded that the Arabic version of the BPNSFS which measures satisfaction and frustration of the three basic needs (autonomy, competency, and relatedness) is proved to be invariant across the five Arab countries and gender and can be used to compare the basic psychological needs in the Arab context.

This study investigated the motor ability and working memory performance of Omani and German primary school-aged children. One hundred eighty-five children from public schools participated in a gross motor test that integrated whole body coordination, three different ball tasks, and a 20-meter run. Furthermore, they completed four working memory tests (the Digit-Span Test forward and backwards and the Corsi Block-Tapping Test forward and backwards). Two MANOVAS with the different motor and working memory tests and one univariate analysis of the general motor ability with the between-subject factors group and gender were conducted. Additionally, correlations between motor ability and working memory scores were executed. German children outperformed Omani children in the overall measurement of motor ability, (p = .01) and all aspects of working memory, (all p< .015). There were no correlations between motor and cognitive variables, when analyzing the results for the Omani and German children separately. These findings may be a result of different educational styles or socioeconomic status and must be investigated in more detail.
