A1 - Class, Fabian A1 - Kohler, Ulrich T1 - Unit nonresponse biases in estimates of SARS-CoV-2 prevalence JF - Survey research methods N2 - Since COVID-19 became a pandemic, many studies are being conducted to get a better understanding of the disease itself and its spread. One crucial indicator is the prevalence of SARS-CoV-2 infections. Since this measure is an important foundation for political decisions, its estimate must be reliable and unbiased. This paper presents reasons for biases in prevalence estimates due to unit nonresponse in typical studies. Since it is difficult to avoid bias in situations with mostly unknown nonresponse mechanisms, we propose the maximum amount of bias as one measure to assess the uncertainty due to nonresponse. An interactive web application is presented that calculates the limits of such a conservative unit nonresponse confidence interval (CUNCI).

It could develop into Chronic Ankle Instability (CAI) causing decreased quality of life, functional performance, early osteoarthritis, and increased risk of other injuries. To develop a strategy of CAI prevention, localized epidemiology data and a valid/reliable tool are essential. However, the epidemiological data of CAI is not conclusive from previous studies and the prevalence of CAI in Taiwanese basketball athletes are not clear. In addition, a valid and reliable tool among the Taiwan-Chinese version to evaluate ankle instability is missing. PURPOSE: The aims were to have an overview of the prevalence of CAI in sports population using a systematic review, to develop a valid and reliable cross-cultural adapted Cumberland Ankle Instability Tool Questionnaire (CAIT) in Taiwan-Chinese (CAIT-TW), and to survey the prevalence of CAI in elite basketball athletes in Taiwan using CAIT-TW. METHODS: Firstly, a systematic search was conducted. Research articles applying CAI related questionnaires in order to survey the prevalence of CAI were included in the review. Second, the English version of CAIT was translated and cross-culturally adapted into the CAIT-TW. The construct validity, test-retest reliability, internal consistency, and cutoff score of CAIT-TW were evaluated in an athletic population (N=135). Finally, the cross-sectional data of CAI prevalence in 388 elite Taiwanese basketball athletes were presented. Demographics, presence of CAI, and difference of prevalence between gender, different competitive levels and play positions were evaluated. RESULTS: The prevalence of CAI was 25%, ranging between 7% and 53%. The prevalence of CAI among participants with a history of ankle sprains was 46%, ranging between 9% and 76%. In addition, the cross-cultural adapted CAIT-TW showed a moderate to strong construct validity, an excellent test-retest reliability, a good internal consistency, and a cutoff score of 21.5 for the Taiwanese athletic population. Finally, 26% of Taiwanese basketball athletes had unilateral CAI while 50% of them had bilateral CAI. In addition, women athletes in the investigated cohort had a higher prevalence of CAI than men. There was no difference in prevalence between competitive levels and among play positions. CONCLUSION: The systematic review shows that the prevalence of CAI has a wide range among included studies. This could be due to the different exclusion criteria, age, sports discipline, or other factors among the included studies. For future studies, standardized criteria to investigate the epidemiology of CAI are required. The CAI epidemiological study should be prospective. Factors affecting the prevalence of CAI ability should be investigated and described. The translated CAIT-TW is a valid and reliable tool to differentiate between stable and unstable ankles in athletes and may further apply for research or daily practice in Taiwan. In the Taiwanese basketball population, CAI is highly prevalent. This might relate to the research method, preexisting ankle instability, and training-related issues. Women showed a higher prevalence of CAI than men. When applying the preventive measure, gender should be taken into consideration. N2 - HINTERGRUND: Verstauchungen des Sprunggelenks sind beim Basketball häufig. Daraus kann sich eine chronische Sprunggelenkinstabilität (Chronic Ankle Instability, CAI) entwickeln, die zu verminderter Lebensqualität, funktioneller Leistung, früher Arthrose und einem erhöhten Risiko für andere Verletzungen führt. Um eine Strategie zur CAI-Prävention zu entwickeln, sind lokalisierte epidemiologische Daten und ein valides/zuverlässiges Instrument erforderlich. Allerdings sind die epidemiologischen Daten von CAI aus früheren Studien nicht schlüssig und die Prävalenz von CAI bei taiwanesischen BasketballsportlerInnen ist nicht klar. Darüber hinaus fehlt ein valides und zuverlässiges Werkzeug in der taiwanesisch-chinesischen Version zur Beurteilung der Sprunggelenkinstabilität. ZIEL: Die Ziele waren, anhand einer systematischen Übersichtsarbeit einen Überblick über die Prävalenz von CAI in der Leistungssportlerpopulation zu erhalten. Zudem sollte ein valides, reliables und kulturübergreifendes Tool für Umfragen der Sprunggelenkinstabilität, in Form des Cumberland Ankle Instability Tool Questionnaire (CAIT) in Taiwan-Chinesisch (CAIT-TW) entwickelt, sowie die Prävalenz von CAI bei Elite-Basketball- Athleten*innen in Taiwan mit Hilfe des CAIT-TW erhoben werden. METHODEN: Zunächst wurde eine systematische Suche durchgeführt. Forschungsartikel, die CAI-bezogene Fragebögen verwenden, um die Prävalenz von CAI zu erheben, wurden in den Reviews aufgenommen. Als nächster Schritt wurde die englische Version des CAIT übersetzt und kulturübergreifend in den CAIT-TW adaptiert. Die Konstruktvalidität, die Test-Retest-Reliabilität, die interne Konsistenz und der Schwellenwert des CAIT-TW wurden in einer Leistungssportlerpopulation (N=135) evaluiert. Schließlich wurden die Querschnittsdaten der CAI-Prävalenz bei 388 taiwanesischen Elite-Basketball-Athleten vorgestellt. Es wurden demografische Daten, das Vorhandensein von CAI und der Unterschied der Prävalenz zwischen den Geschlechtern in verschiedenen Wettkampfniveaus und Spielpositionen ausgewertet. ERGEBNISSE: Die Prävalenz von CAI betrug 25 % und lag zwischen 7 % und 53 %. Die Prävalenz von CAI unter den Teilnehmern mit einer Vorgeschichte von Sprunggelenksverstauchungen lag bei 46 % und reichte von 9 % bis 76 %. Darüber hinaus zeigte der kulturübergreifend adaptierte CAIT-TW eine mäßige bis starke Konstruktvalidität, eine ausgezeichnete Test-Retest-Reliabilität, eine gute interne Konsistenz und einen Grenzwert von 21,5 für die taiwanesische Sportlerpopulation. Schließlich wiesen 26% der taiwanesischen Basketball-Athletinnen ein unilaterales CAI auf, während 50% von ihnen ein bilaterales CAI hatten. Darüber hinaus hatten weibliche Sportler in der untersuchten Kohorte eine höhere Prävalenz von CAI als Männer. Es gab keinen Unterschied in der Prävalenz zwischen den Leistungsniveaus und zwischen den Spielpositionen. SCHLUSSFOLGERUNG: Der systematische Review zeigt, dass die Prävalenz von CAI unter den eingeschlossenen Studien eine große Bandbreite aufweist. Dies könnte auf die unterschiedlichen Ausschlusskriterien, das Alter, die Sportdisziplin oder andere Faktoren in den berücksichtigten Studien zurückzuführen sein. Für zukünftige Studien werden standardisierte Kriterien zur Untersuchung der Epidemiologie von CAI benötigt. Epidemiologische Studien zu CAI sollten daher prospektiv angelegt sein. Zudem sollten Faktoren, die die Prävalenz der CAI-Fähigkeit beeinflussen, untersucht und beschrieben werden. Der übersetzte CAIT-TW ist ein valides und zuverlässiges Instrument zur Unterscheidung zwischen stabilen und instabilen Sprunggelenken bei Sportlerinnen und kann für die Forschung oder die tägliche Praxis in Taiwan weiterverwendet werden. In der taiwanesischen Basketballpopulation ist CAI stark verbreitet. Dies könnte mit der Untersuchungsmethode, einer vorbestehenden Sprunggelenksinstabilität und trainingsbedingten Problemen zusammenhängen. Frauen zeigten eine höhere Prävalenz von CAI als Männer. Bei der Anwendung der Präventionsmaßnahme sollte das Geschlecht berücksichtigt werden.

Because most of the evidence on teen dating violence (TDV) synthesized in reviews comes from North American studies, this review aimed to compile evidence on prevalence rates of TDV based on studies identified for Europe only. Specifically, we considered different forms of TDV victimization and perpetration, gender differences, and its measurement. A systematic literature search of the most popular databases Ebsco and PubMed yielded a total of N = 34 studies, with most of the studies identified for Spain, and only a few studies in other European countries. In sum, the results revealed a great variability in prevalence rates across and within the European countries, a common pattern of gender differences, and a wide range of applied measures, corresponding with the evidence from the North American studies. Implications for future research and policy were discussed.
