Tidskriftsartikel (refereegranskat)abstract
- The Danish national return-to-work (RTW) program aims to improve the management of municipal sickness benefit in Denmark. A study is currently ongoing to evaluate the RTW program. The purpose of this article is to describe the study protocol. The program includes 21 municipalities encompassing approximately 19 500 working-age adults on long-term sickness absence, regardless of reason for sickness absence or employment status. It consists of three core elements: (i) establishment of multidisciplinary RTW teams, (ii) introduction of standardized workability assessments and sickness absence management procedures, and (iii) a comprehensive training course for the RTW teams. The effect evaluation is based on a parallel group randomized trial and a stratified cluster-controlled trial and focuses on register-based primary outcomes-duration of sickness absence and RTW and questionnaire-based secondary outcomes such as health and workability. The process evaluation utilizes questionnaires, interviews, and municipal data. The effect evaluation tests whether participants in the intervention have a (i) shorter duration of full-time sickness absence, (ii) longer time until recurrent long-term sickness absence, (iii) faster full RTW, (iv) more positive development in health, workability, pain, and sleep; it also tests whether the program is (v) cost-effective. The process evaluation investigates: (i) whether the expected target population is reached; (ii) if the program is implemented as intended; (iii) how the beneficiaries, the RTW teams, and the external stakeholders experience the program; and (iv) whether contextual factors influenced the implementation. The program has the potential to contribute markedly to lowering human and economic costs and increasing labor force supply. First results will be available in 2013. The trial registrations are ISRCTN43004323, and ISRCTN51445682.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- From 4 to 7 April 2016, 24 researchers from 8 countries and from a variety of academic disciplines gathered in Snekkersten, Denmark, to reach evidence-based consensus about physical activity in children and youth, that is, individuals between 6 and 18 years. Physical activity is an overarching term that consists of many structured and unstructured forms within school and out-of-school-time contexts, including organised sport, physical education, outdoor recreation, motor skill development programmes, recess, and active transportation such as biking and walking. This consensus statement presents the accord on the effects of physical activity on children's and youth's fitness, health, cognitive functioning, engagement, motivation, psychological well-being and social inclusion, as well as presenting educational and physical activity implementation strategies. The consensus was obtained through an iterative process that began with presentation of the state-of-the art in each domain followed by plenary and group discussions. Ultimately, Consensus Conference participants reached agreement on the 21-item consensus statement.

- This study investigates the enjoyment and cohesion of school children participating in a school-based high-intensity physical activity (PA) intervention. Both enjoyment and cohesion have been found to be important factors for adherence to regular physical and sport activity, an important outcome of PA interventions. The sample consisted of 300 pupils (mean age: 9.3 years; 52.7% female) assigned to a team sport intervention, an individual sport intervention, or a control group for 10 months. The Physical Activity Enjoyment Scale and Youth Sport Environment Questionnaire were used to measure enjoyment and cohesion. The Yo-Yo IR1C test determined fitness improvements. Results showed that enjoyment and cohesion (social) measured at the beginning of the intervention significantly predict fitness improvements achieved after 10 months. No differing developmental effects over time could be found in the intervention groups with regard to cohesion and enjoyment when comparing them to the control group. However, enjoyment and cohesion (social) significantly decreased in the groups that performed individual sports. Team sports seem to be more advantageous for the development of enjoyment and cohesion, which are both factors that positively impact the health outcomes of the intervention. © 2016 European College of Sport Science.

- The present study describes the development and validation of an instrument to measure volition in the exercise context. Volition describes an individual’s self-regulatory mental processes that are responsible for taking and maintaining a desirable action (e.g., exercising regularly). The scale structure was developed in an exploratory factor analysis which resulted in a reliable structure of the following six factors: Volitional Inhibition—Reasons, Volitional Inhibition—Postponing Training, Volitional Facilitation—Self-Confidence, Volitional Inhibition—Unrelated Thoughts, Volitional Inhibition—Approval From Others, and Volitional Facilitation—Coping with Failure. A sound theoretical explanation for these six factors is based on the Personal System Interaction Theory. This six-factor structure was also confirmed in a new sample in a confirmatory factor analysis, delivering an 18-item questionnaire with strong model fit and good internal consistency. In addition, the Volition in Exercise Questionnaire showed convergent validity because it was able to predict exercise participation. It showed incremental validity by explaining additional variance to the Sport Motivation Scale’s well-established predictors of exercise participation. © 2016 Taylor & Francis.

- Purpose: The purpose of this study was to translate and validate a Danish version of the coach-created Empowering and Disempowering Motivational Climate Questionnaire (EDMCQ-C), retest the factor structure and provide further investigation into the psychometric properties in terms of measurement invariance across gender, age and competitive level, reliability and predictive validity. Methods: The participants were 1719 male and 551 female Danish football players 12–20 years of age (M = 14.81) playing at recreational, medium and elite levels. Participants filled in EDMCQ-C as well as questionnaires measuring psychological needs (BPNESS) and behaviour regulation (BRSQ). Factor structure of the EDMCQ-C was tested using Exploratory Structural Equation Modelling. To test whether the factor structure differed across gender, age group and competitive level, an invariance analysis comparing configurational, metric and scalar models was conducted. Results: EDMCQ-C showed good psychometric properties and measurement invariance across age, gender and competitive level. Both dimensions of EDMCQ-C were associated to needs satisfaction and behaviour regulation in expected directions and had high internal consistency. Conclusion: This study provides evidence for the reliability of the two dimensions of EDMCQ-C, their predictive validity and for measurement invariance across age, gender and competitive level and provides a Danish version of the EDMCQ with sound psychometric properties. © 2023 Informa UK Limited, trading as Taylor & Francis Group.

- The purpose of this study was to investigate the importance of motivational climate for the satisfaction of psychological needs and dropout in recreational, intermediate and elite volleyball. Seven thousand nine hundred thirty six volleyball players from all 321 volleyball clubs across Denmark were invited to participate in the study. Three thousand three thirty answered the questionnaire and 2150 were included in the analysis. Dropout from Volleyball was measured as the proportion of players that had stopped playing volleyball over the last year. The coach-created motivational climate was measured using the Motivational Climate Scale for Youth Sports. The satisfaction of players’ psychological needs was measured using an adapted version of the basic psychological needs in exercise scale. The psychometric scales were validated and showed good model fit. For volleyball players of all levels, the degree of mastery climate predicted the satisfaction of the players’ basic psychological needs satisfaction during volleyball which was, in turn, associated with lower dropout rates. Performance climate had a weak negative association with the satisfaction of psychological needs on the intermediate level only. When adjusting the models for the negative association between performance climate and mastery climate this negative association became nonsignificant and a weak positive association to needs satisfaction emerged for players at the elite level. Findings confirm that the coach-created mastery climate in volleyball teams is important for the satisfaction of players’ basic psychological needs and continuation within the sport across the recreational, intermediate and elite levels. Highlights Coach-created mastery climate in volleyball teams was positively associated with the satisfaction of the players’ basic psychological and negatively associated with dropout. These associations between coach created climate, need satisfaction and dropout were similar across different sporting levels. Performance orientation had little influence and seemed mainly problematic if it was at the expense of mastery climate. © 2022 European College of Sport Science.

- A trend toward greater body size in dizygotic (DZ) than in monozygotic (MZ) twins has been suggested by some but not all studies, and this difference may also vary by age. We analyzed zygosity differences in mean values and variances of height and body mass index (BMI) among male and female twins from infancy to old age. Data were derived from an international database of 54 twin cohorts participating in the COllaborative project of Development of Anthropometrical measures in Twins (CODATwins), and included 842,951 height and BMI measurements from twins aged 1 to 102 years. The results showed that DZ twins were consistently taller than MZ twins, with differences of up to 2.0 cm in childhood and adolescence and up to 0.9 cm in adulthood. Similarly, a greater mean BMI of up to 0.3 kg/m(2) in childhood and adolescence and up to 0.2 kg/m(2) in adulthood was observed in DZ twins, although the pattern was less consistent. DZ twins presented up to 1.7% greater height and 1.9% greater BMI than MZ twins; these percentage differences were largest in middle and late childhood and decreased with age in both sexes. The variance of height was similar in MZ and DZ twins at most ages. In contrast, the variance of BMI was significantly higher in DZ than in MZ twins, particularly in childhood. In conclusion, DZ twins were generally taller and had greater BMI than MZ twins, but the differences decreased with age in both sexes.

- The objective of thermonuclear fusion consists of producing electricity from the coalescence of light nuclei in high temperature plasmas. The most promising route to fusion envisages the confinement of such plasmas with magnetic fields, whose most studied configuration is the tokamak. Disruptions are catastrophic collapses affecting all tokamak devices and one of the main potential showstoppers on the route to a commercial reactor. In this work we report how, deploying innovative analysis methods on thousands of JET experiments covering the isotopic compositions from hydrogen to full tritium and including the major D-T campaign, the nature of the various forms of collapse is investigated in all phases of the discharges. An original approach to proximity detection has been developed, which allows determining both the probability of and the time interval remaining before an incoming disruption, with adaptive, from scratch, real time compatible techniques. The results indicate that physics based prediction and control tools can be developed, to deploy realistic strategies of disruption avoidance and prevention, meeting the requirements of the next generation of devices.

- The purpose of this study was to investigate whether Danish children from immigrant backgrounds are less physically active than children from the ethnic majority, and to investigate the possible reasons for any differences found. Accelerometer measures of physical activity as well as questionnaire data about organised sports, family demography, resources and values were collected from 594 children of whom 67 had other ethnic background than Danish. Data were collected when the children were 6-7 years old and again later when the children were 9-10 years old. It was found that children from immigrant backgrounds were not less physically active than other children when their amounts of daily physical activity were measured by direct objective measures, despite their participation rate in organised sports being much lower. Using multiple logistic regression modelling, this study showed that lack of parental experience with organised sports and lack of economic/material resources explained much of the difference in sports participation. Children of immigrant background had significant lower participation in club sports but this did not affect their overall physical activity level.
