Summary
The Italian Dance Functional Outcome Survey (DFOS-IT) is a reliable and valid tool for assessing injured adult dancers. This validated survey effectively measures outcomes and aids in screening for dancers with lower extremity or low back injuries.
Area of Science:
- Dance science
- Clinical measurement
- Psychometrics
Background:
- The Dance Functional Outcome Survey (DFOS) is a key tool for assessing functional outcomes in dancers.
- Cultural adaptation and validation are crucial for its use in diverse populations, such as Italian dancers.
Purpose of the Study:
- To translate and culturally adapt the DFOS into Italian (DFOS-IT).
- To validate the psychometric properties of the DFOS-IT for use in adult dancers.
Main Methods:
- The DFOS-IT underwent rigorous translation and back-translation processes.
- Test-retest reliability was assessed in 58 dancers (ICC≥0.98).
- Construct validity, internal consistency (α=0.93), and sensitivity (AUC≥0.80) were evaluated in 265 dancers, with responsiveness assessed in 44 dancers.
Main Results:
- The DFOS-IT demonstrated excellent test-retest reliability and high internal consistency.
- Strong construct validity was found when compared to the SF-36.
- The instrument showed excellent sensitivity and responsiveness to change, with no floor or ceiling effects.
Conclusions:
- The DFOS-IT is a psychometrically sound instrument for Italian adult dancers.
- It serves as a valid, reliable, and responsive outcome and screening measure for dancers with lower extremity or low back injuries.
