French translation and validation of the Keele STarT MSK Tool
2021
Background
The Keele STarT MSK Tool is a 10-item questionnaire developed to classify patients suffering from one of the five most common types of musculoskeletal pain into 3 sub-groups of risk of chronic pain (i.e. low risk, medium risk and high risk).
Objective
The objective of the present study was to translate the Keele STarT MSK Tool into French and to evaluate its main psychometric properties.
Methods
The translation and intercultural adaptation of the questionnaire were carried out using a 6-step process. The following psychometric properties were investigated: floor and ceiling effects, construct validity, internal consistency and test-retest reliability including Standard Error of Measurement and Smallest Detectable Change.
Results
101 patients suffering from musculoskeletal pain participated in the study. No floor nor ceiling effects were observed. A Cronbach’s alpha of 0.65 was found, revealing a moderate internal consistency. Nevertheless, all items were demonstrated to be significantly correlated with the total score (range of correlations: r=0.2 for item 7 to r=0.78 for item 1). A good construct validity was also found with a significant correlation of r=0.78 between the French Keele STarT MSK Tool and the OMPSQ-short. Test-retest reliability was excellent (Intraclass Correlation Coefficient 0.97). A Standard Error of Measurement of 0.42 and a Smallest Detectable Change of ±1.17 were measured.
Conclusion
A validated French version of the Keele STarT MSK Tool is now available and can be used by health practitioners to stratify patients as being at low, medium or high risk of persistent musculoskeletal pain.
