Introduction:
Dancers generally begin training in a variety of styles at a young age. Across ages and levels of participation, dancers are at high risk for injury. Most available injury surveillance tools, however, have been developed for adult populations. Valid, reliable tools that monitor injury and exposure of pre-adolescent dance populations are limited. Therefore, the purpose of this study was to determine the validity and reliability of a dance injury and participation questionnaire specifically for pre-adolescent private studio dancers.
Methods:
Four stages of validity and reliability testing assessed a novel questionnaire: initial design based on previous literature, expert panel review, cognitive interviews, and test-retest reliability. The target population was 8 to 12-year-olds who participate in at least 1 class/week at a private studio. Feedback from a panel review and cognitive interviews was incorporated. Test-retest analyses included Cohen's kappa coefficients and percent agreement for categorical variables, and intraclass correlation coefficients [ICCs (3,1)], absolute mean difference (md) and Pearson's correlation coefficients (r) for numerical data.
Results:
The final questionnaire was comprised of 4 sections: demographics, dance training history, current dance participation (previous 1-year and 4-months), and dance-related injury history (previous 1-year and 4-months). Items with categorical responses estimated kappa coefficients from 0.32 to 1.00, and percent agreement between 81% and 100%. For items with numeric responses, ICC estimates ranged between .14 and 1.00, r values between .14 and 1.00, and the largest absolute md was 0.46. The 4-month recall sections revealed higher agreement than the 1-year sections.
Conclusion:
This valid pre-adolescent dance injury and participation questionnaire demonstrates good to excellent reliability across all items. To support participant completions, assistance from a parent/guardian is suggested. To move dance epidemiology research forward among private studio dancers aged 8 to 12 years, employment of this questionnaire is therefore recommended.
