Most physical education intervention studies on the positive effect of sports on self-concept development have attempted to increase schoolchildren’s self-concept without taking the veridicality of the self-concept into account. The present study investigated whether a 10-week intervention in physical education would lead to an increase not only in the general level of self-concept of endurance and self-concept of strength but also in its veridicality in those who had previously under- or overestimated their abilities. A total of 464 primary schoolchildren (246 boys, 218 girls, Mage = 11.9) either participated in the intervention or served as controls. The intervention group received endurance and strength training during physical education lessons carried out with a consistent individualized teacher frame of reference (iTFR). Results showed that this specific intervention was associated with increases not only in the general level of self-concept but also in its veridicality in under- and overestimators. Results are discussed in terms of didactic methods to promote functional self-concepts in physical education.

Exposure to farming environments has been shown to protect substantially against asthma and atopic disease across Europe and in other parts of the world. The GABRIEL Advanced Surveys (GABRIELA) were conducted to determine factors in farming environments which are fundamental to protecting against asthma and atopic disease. The GABRIEL Advanced Surveys have a multi-phase stratified design. In a first-screening phase, a comprehensive population-based survey was conducted to assess the prevalence of exposure to farming environments and of asthma and atopic diseases (n = 103,219). The second phase was designed to ascertain detailed exposure to farming environments and to collect biomaterial and environmental samples in a stratified random sample of phase 1 participants (n = 15,255). A third phase was carried out in a further stratified sample only in Bavaria, southern Germany, aiming at in-depth respiratory disease and exposure assessment including extensive environmental sampling (n = 895). Participation rates in phase 1 were around 60% but only about half of the participating study population consented to further study modules in phase 2. We found that consenting behaviour was related to familial allergies, high parental education, wheeze, doctor diagnosed asthma and rhinoconjunctivitis, and to a lesser extent to exposure to farming environments. The association of exposure to farm environments with asthma or rhinoconjunctivitis was not biased by participation or consenting behaviour. The GABRIEL Advanced Surveys are one of the largest studies to shed light on the protective 'farm effect' on asthma and atopic disease. Bias with regard to the main study question was able to be ruled out by representativeness and high participation rates in phases 2 and 3. The GABRIEL Advanced Surveys have created extensive collections of questionnaire data, biomaterial and environmental samples promising new insights into this area of research.

The present study aims to investigate the implications of web-based delivery of identical learning content for time efficiency and students' performance, as compared to conventional textbook resources.
Quality evaluation of the available Internet information regarding pain during orthodontic treatment

OBJECTIVE To investigate the quality of the data disseminated via the Internet regarding pain experienced by orthodontic patients. MATERIALS AND METHODS A systematic online search was performed for 'orthodontic pain' and 'braces pain' separately using five search engines. The first 25 results from each search term-engine combination were pooled for analysis. After excluding advertising sites, discussion groups, video feeds, and links to scientific articles, 25 Web pages were evaluated in terms of accuracy, readability, accessibility, usability, and reliability using recommended research methodology; reference textbook material, the Flesch Reading Ease Score; and the LIDA instrument. Author and information details were also recorded. RESULTS Overall, the results indicated a variable quality of the available informational material. Although the readability of the Web sites was generally acceptable, the individual LIDA categories were rated of medium or low quality, with average scores ranging from 16.9% to 86.2%. The orthodontic relevance of the Web sites was not accompanied by the highest assessment results, and vice versa. CONCLUSIONS The quality of the orthodontic pain information cited by Web sources appears to be highly variable. Further structural development of health information technology along with public referral to reliable sources by specialists are recommended.

Vor dem Hintergrund, dass es bis anhin nicht gelungen ist, empirische Evidenz für das pädagogische Postulat der Persönlichkeitsentwicklung durch Sport vorzulegen, haben sich im letzten Jahrzehnt diverse Forschungsgruppen der Selbstkonzeptentwicklung im Sport (-unterricht) angenommen (z. B. Neuber, 2007). In zunehmendem Masse werden dabei quasi-experimentelle Interventionsstudien (eine Übersicht findet sich z. B. bei Fox, 2000) durchgeführt, wobei allerdings häufig auf die Evaluation der Implementationsgenauigkeit verzichtet wird. Die vorliegende Studie nimmt sich diesem Defizit an und untersucht im Rahmen der sportpädagogischen Evaluationsforschung sowohl die Implementation als auch die Wirksamkeit einer selbstkonzeptfördernden Intervention im Sportunterricht. Es wird überprüft, ob die Implementation einer individuellen Bezugsnormorientierung (IBNO) von Lehrpersonen zu positiven Veränderungen im sportbezogenen Fähigkeitsselbstkonzept (SFSK) von Schülerinnen und Schülern führt. Die Lehrpersonen von 5. Primarklassen der Versuchsgruppe wurden während der zwanzigwöchigen Intervention (quasi-experimentelle Längsschnittstudie mit Versuchs- und Kontrollgruppe) aufgefordert, den Sportunterricht anhand einer individuellen Bezugsnormorientierung zu gestalten. Die Prüfung der schülerperzipierten IBNO und des SFSK (NSchülerInnen = 203, Alter: MAlter = 12.0, 46.8% weiblich, nVG = 96, nKG = 107) erfolgte mittels zweifaktorieller Varianzanalyse mit Messwiederholung. Zudem wird die Häufigkeit der Nutzung eines individuellen Lernjournals durch die Schülerinnen und Schüler analysiert. Das Lernjournal wurde im Mittel 42.6 mal (SD = 12.2) im Unterricht benutzt. Die schülerperzipierte IBNO und das SFSK der Versuchsgruppe nehmen im Verlauf der Intervention im Vergleich zur Kontrollgruppe zu (sig. Interaktionseffekt; IBNO: F(1,201) = 6.35, p = .012, η2 = .031; SFSK: F(1,201) = 6.44, p = .012, η2 = .031). Die Ergebnisse zeigen, dass die Intervention umgesetzt wurde und zu den beabsichtigten Wirkungen führte. Dies deutet auf die Möglichkeiten einer IBNO zur Selbstkonzeptförderung im Sportunterricht und auf die Relevanz der Implementationsevaluation zur Erklärung von Programmwirkungen hin.
