简要总结
Study Design: Evaluation of the psychometric properties of a translated, culturally adapted questionnaire.
Objective: Translating, culturally adapting, and validating the Italian version of the Dance Functional Outcome Survey (DFOS-IT), allowing its use with Italian-speaking dancers to evaluate their musculoskeletal health and wellbeing inside and outside Italy.
Summary of Background Data: Musculoskeletal injuries are a phenomenon of huge prevalence and has been a major focus within peer-reviewed literature since the 1980s.
Growing attention is devoted to standardized outcome measures to improve interventions for injured dancers.
A translated form of the DFOS, the only existing outcome measure that focus on the unique functional requirements of dancers, has never been validated within the Italian dancers population.
详细描述
The DFOS is a dance-specific, lower extremity and low back functional outcome measure, the first and only existing at the moment.
The DFOS-IT questionnaire will be developed involving forward-backward translation, a final re-evaluation made by a representative multidisciplinary expert committee and the realization of a prefinal version to establish a proper correspondence with the original English latest version.
A factor analysis and analyses of internal consistency, construct validity, internal responsiveness and sensitivity will be conducted. The reliability will be measured for internal consistency (Cronbach α) and a factor analysis will be applied to analyse the internal structure. The divergent validity will be measured by comparing the data obtained from the compilation of the DFOS-IT with those of the SF-36 to evaluate the psychometric properties and the equivalence of the results adapted to the Italian language and culture.
The validation of the psychometric properties of the instrument will start after it will been administered digitally, via a link to a website built using LimeSurvey, an application based on a MySQL database that allows the realization of online surveys, to a sample population of at least 140 dancers (10 subjects for each item of DFOS-IT) professionals or pre-professionals of age recruited through companies, professional academies, dance high schools and health professionals working with dancers. Through this link, from the time it will be online up to 30 September 2019, the dancers who will give their informed consent to their voluntary participation, will be able to access the online questionnaire.
Upon enrollment, dancers will answer a demographics questionnaire, the DFOS-IT, and the SF-36. If they will take part in the reliability portion, then they filled out the DFOS-IT a second time within 4 to 9 days and, if in the responsiveness testing, a third time after 4-months.

结局指标
主要结局
Dance Functional Outcome Score
时间窗: 1 day
Self-reported functional outcome questionnaire for ballet and modern dance populations, applicable to musculoskeletal injuries of the low back and lower extremities. The 14-question DFOS assesses the dancer's ability in areas of activities of daily living (ADL, 40 points) and dance technique (technique, 50 points). Total score from 0 to 90, subscore Activities of daily living 40, Technique 50. Higher scores represent better outcomes. Total points are normalized to a percentage, with 100% representing full function without limitations.
Validate the Italian translation of the DFOS
时间窗: 1 day
The score between the DFOS-IT versus the italian validated version of the SF-36 will be compared
