Abstract

The objective of the present study was to translate and validate the Canadian Readiness for Return To Work instrument (RRTW-CA) into a Danish version (RRTWDK) by testing its test–retest and internal consistency reliability and its structural and construct validity. Cross-cultural adaptation of the six-staged RRTW-CA instrument was performed in a standardised, systematic five-step-procedure; forward translation, panel synthesis of the translation, back translation, consolidation and revision by researchers, and finally pre-testing. This RRTW-DK beta-version was tested for its psychometric properties by intra-class correlation coefficient and standard error of measurement (n = 114), Cronbach’s alpha (n = 471), confirmatory factor analyses (n = 373), and Spearman’s rank correlation coefficient (n = 436) in sickness beneficiaries from a municipal employment agency and hospital wards. The original RRTW-CA stage structure could not be confirmed in the RRTWDK. The psychometric properties were thus inconclusive. The RRTW-DK cannot be recommended for use in the current version as the RRTW construct is questionable. The RRTW construct needs further exploration, preferably in a population that is homogeneous with regard to cause of sickness, disability duration and age.

Compliance with Ethical Standards

Conflict of interest

Author Christina Malmose Stapelfeldt, Anne-Mette Hedeager Momsen, Thomas Lund, Therese Koops Grønborg, Sheilah Hogg-Johnson, Janne Skakon, Chris Jensen and Merete Labriola declare that they have no conflict of interest.

Ethical Approval

All procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation (institutional and national) and with the Helsinki Declaration of 1975, as revised in 2000. Approval for the use of questionnaire data was obtained from the Central Region Denmark (Danish Data Protection Agency j. no. 1-16-02-404-14). According to Danish law, approval from the Danish National Committee on Biomedical Research Ethics (http://www.cvk.sum.dk) was not relevant as approval is required only for projects using biological material or involving biomedical treatment. Participation in the study was voluntary, and answers were processed anonymously.
