Characteristics, Properties, and Associations of Self-Assessed Pain Questionnaires: A Literature Review and Prospective Cohort Study Among Dance Students.

Objectives: To provide an overview of measurement properties of the Oslo Sports Trauma Research Center Questionnaire (OSTRCQ), pain visual analogue scale (VAS-pain) and Self-Estimated Functional Inability Because of Pain (SEFIP) scale in dance populations, and to investigate the relationship between these questionnaires in pre-professional contemporary dancers.

Methods: A search of PubMed was conducted and studies were included if they 1) used one of the three questionnaires within a dance population and 2) assessed the reliability, validity, or responsiveness of the questionnaire(s). 134 dance students (67.5% female; 19.4±1.5 yrs) were prospectively followed during 1 academic year. The OSTRCQ, VAS-pain, SEFIP, and injuries were self-assessed on a monthly basis. Pearson correlation analyses and repeated measures correlation analyses were performed to identify possible associations.

Results: The literature overview resulted in two studies describing measurement properties of the SEFIP (n=1) and OSTRCQ (n=1). Prevalence of injuries ranged from 23.1 to 42.6%. Weak monthly correlations (r=0.14-0.50) were found between OSTRCQ and SEFIP. Moderate monthly correlations (r=0.54-0.71) were found between OSTRCQ and VAS-pain, and weak/moderate monthly correlations (r=0.30-0.62) were found between SEFIP and VAS-pain. Repeated measures correlation demonstrated a moderate overall correlation between ORSTCQ and VAS-pain (r=0.57), with weak overall correlations between ORSTCQ and SEFIP (r=0.26) and SEFIP and VAS-pain (r=0.34).

Conclusions: Studies on measurement properties of questionnaires in dance are scarce. Weak/moderate associations were found between the OSTRCQ, SEFIP, and the VAS-pain questionnaires. Future high-quality research should investigate measurement properties of these questionnaires within dance populations. The results contribute by substantiating choices when developing a surveillance system.
