Published on: 2019-06-03

Abstract

Introduction: The assessment of adherence forms an important part of positive treatment outcomes, and there is need to adapting them to the Dutch population.
Objective: To evaluate the inter-rater reliability of the Dutch version of the Rehabilitation Adherence Measure for Athletic Training (RAdMAT-NL) in patients who are undertaking physiotherapeutic rehabilitation in a primary physiotherapy practice.
Design and procedure: Two groups participated in a cross-sectional study conducted between 1 November and 1 December 2017. Two matched physiotherapists independently assessed the adherence of a patient at the end of a treatment using the Dutch version of the 16-item RAdMAT. The inter-rater reliability was evaluated using the intraclass correlation coefficient (ICC) (2,1). The ICC was calculated for all the participants together, after which it was calculated again for patients with musculoskeletal injuries and patients with chronic diseases separately.
Participants: 36 patients—18 with musculoskeletal injuries and 18 with chronic diseases (MS, COPD, dystrophy, Parkinson’s disease and partial paraplegia).
Results: The inter-rater reliability of the RAdMAT-NL is excellent: ICC = 0.98 for all the participants. The inter-rater reliability is also excellent for patients with musculoskeletal injuries (ICC = 0.98) and patients with chronic diseases (ICC = 0.99).
Conclusion: The inter-rater reliability of the RAdMAT-NL is excellent in patients who are undertaking physiotherapeutic rehabilitation in a primary physiotherapy practice.
