Application of the Scale for Assessment and Rating of Ataxia in toddlers

Introduction: In young children with early onset ataxia (EOA), quantitative rating of ataxia by the Scale for Assessment and Rating of Ataxia (SARA) is longitudinally influenced by the physiological age effect on motor coordination. To enable longitudinal quantitative interpretation of ataxia by SARA in children with EOA, the EPNS ataxia working group has previously determined SARA-scores in typically developing children (4-16 years of age). In toddlers, this information is still lacking. We therefore aimed to investigate the feasibility and reliability of SARA-scores in typically developing toddlers. Methods: In 57 typically developing toddlers (2-4 years), we aimed to determine the: 1. feasibility of SARA -scores, 2. age-related pre-requisites to obtain SARA-scores in toddlers over all domains, 3. SARA-score reliability, 4. mathematical age connection of SARA-scores in toddlers and older children. Results: In typically developing toddlers, the feasibility of SARA is strongly age-dependent (p < .000). After computing compensations for two age-related, unfeasible and therefore un-assessable kinetic subtasks and after allowing the videotaping of non-kinetic SARA sub-task performances at home, the SARA was fully reliably assessable in all (n = 57) toddlers (ICC = 0.732). From two to 16 years of age, SARA-scores were mathematically represented by one continuous, exponentially decreasing trend line approaching the adult-optimum at 16 years of age. Conclusion: In toddlers, SARA-scores are reliably assessable, by using two age-compensations and allowing the videotaping of SARA-performances partly at home. In children with EOA, these data enable longitudinal quantification and interpretation of quantitative ataxia-scores by SARA from 2 years of age throughout childhood

Evaluatie van de milieu-impact van WArrelnet- en boomKOrvisserij op het Belgisch deel van de Noordzee (WAKO). Eindrapport

The project WAKO wants to give a first attempt to map the current knowledge and the knowledge gaps on the effects of trammel net and beam trawl fisheries for the Belgian part of the North Sea. The project focuses on three ecosystem components, i.e. benthic invertebrates, sea birds and marine mammals. The aim of this project consists of three phases: (1) compilation and analysis of existing, experimental data for the Belgian part of the North Sea on the effects of trammel net and beam trawl fisheries; (2) current knowledge on the impact of beam trawl and trammel/gill net fisheries, based on literature review and (3) evaluation of the direct effects of beam trawl and trammel/gill net fisheries on three ecosystem components, knowledge gaps and investigation of an appropriate methodology to evaluate the environmental impact of fishing gears.WAKO indicates that direct, short-term effects of trammel net and beam trawl fisheries are clearly directed to different ecosystem components. Similarities between analogous, scientific studies allow a first evaluation of the effects, but quantitative data (on both biological impact data and data related to fishing effort and distribution) are so far insufficient to allow the development of a decision support tool for environmental and fisheries management

Predicting change in middle school students’ leisure‐time physical activity participation: A prospective test of the trans‐contextual model

© 2020 The Authors. Journal of Applied Social Psychology published by Wiley Periodicals LLC We applied the trans-contextual model (TCM) to examine the effects of middle school students’ perceived autonomy support from their physical education (PE) teachers on autonomous motivation toward PE in school and, critically, autonomous motivation toward, and actual participation in, leisure-time physical activity (PA). The research adopted a three-wave prospective design enabling the modeling of change in the TCM constructs over time. Middle school students (N=248) aged from 12 to 16years reported their perceived autonomy support, autonomous motivation in PE, autonomous motivation toward leisure-time PA, attitudes, subjective norms, perceived behavioral control (PBC), intentions for PA in leisure-time, and leisure-time PA participation. The psychological constructs and leisure-time PA were measured at baseline (T0) and at a first follow-up occasion (T1) 5weeks later. Another measure of PA was taken at a second follow-up occasion (T2) a further 5weeks later. A single-indicator structural equation model using residualized change scores revealed that perceived autonomy support predicted autonomous motivation in PE (β=.345), and autonomous motivation in PE predicted autonomous motivation for leisure-time PA (β=.484). Autonomous motivation toward leisure-time PA predicted attitudes (β=.425), subjective norms (β=.264), and PBC (β=.517). Autonomous motivation toward leisure-time PA (β=.376), attitude (β=.231), and subjective norms (β=.185) predicted intentions toward leisure-time PA, and intentions predicted PA (β=.198). Findings extend research on the TCM by demonstrating its efficacy in predicting change in middle school students’ autonomous motivation across PE and leisure-time contexts, and accounting for change in intentions toward, and actual participation in, leisure-time PA

Testing a physical education-delivered autonomy supportive intervention to promote leisure-time physical activity in lower secondary school students : the PETALS trial

BackgroundInadequate physical activity in young people is associated with several physical and mental health concerns. Physical education (PE) is a potentially viable existing network for promoting physical activity in this population. However, little research has been conducted on whether PE teachers can influence students' engagement in leisure-time physical activity. The present study therefore examined the efficacy of an intervention aimed at increasing PE teachers' autonomy support on students' leisure-time physical activity (the PETALS trial). The intervention was guided by the trans-contextual model (TCM) explaining the processes by which PE teachers' provision of autonomy support during PE promotes students' motivation and engagement in physical activity in their leisure time.MethodsThe study adopted a cluster-randomized, waitlist control intervention design with randomization by school. Participants were PE teachers (N=29, 44.83%female; M age=42.83, SD=9.53yrs) and their lower secondary school students (N=502, 43.82%female; M age=14.52, SD=0.71yrs). We measured TCM constructs, including perceived autonomy support, autonomous motivation in PE and leisure time, beliefs and intentions towards leisure-time physical activity, and physical activity behavior at baseline, post-intervention, and at one-, three-, and six-months. Study hypotheses were tested through a series of ANOVAs and structural equation models using post-intervention and one-month follow-up data.ResultsWe found no changes in TCM constructs or physical activity behavior in either group at post-intervention or at 1 month. Path analyses supported two propositions of the TCM as change variables: perceived autonomy support had a significant effect on autonomous motivation in PE and autonomous motivation in PE had a significant effect on autonomous motivation in leisure time. Although we found a direct effect of autonomous motivation in leisure time on physical activity, we did not find support for the third premise of the TCM that autonomous motivation in leisure time indirectly affects physical activity through beliefs and intentions.ConclusionsCurrent findings did not support the efficacy of the PETALS intervention at changing physical activity behavior and TCM constructs. More research is required to determine whether the TCM predictive validity is supported when other model variables are manipulated through experimental and intervention studies.Trial registrationISRCTN, ISRCTN39374060.
