Background Patient reported assessments are widely recommended by the clinical guidelines and an important part of a comprehensive assessment. Patient-reported questionnaires should be translated into local language accordingly and validated in the translated language (1). The clinicians in Romania suffer from lack of validated questionnaires in Romanian language. The Roland Morris Disability questionnaire is one of the most recommended questionnaires evaluating low back pain. Although, the Romanian translation was performed before, there is no effort regarding to its validation in Romanian language until now.
Objectives To investigate the test-retest reliability Romanian version of the Roland Morris Disability Questionnaire (RMDQ-Ro) in people low back pain.
Methods The permission to conduct such a study was asked to the original author Prof. Martin Roland, before starting to the study. The Romanian translated form of Roland Morris Disability Questionnaire which is provided on the web site “http://www.rmdq.org/” was used in the study. A total of 100 people with low back pain filled the RMDQ as well as Numeric Rating Scales for rest (NRS-R) and activity (NRS-A). Due to the lack of other validated measures such the Oswestry Disability Index in Romanian, these additional assessments (VAS-R and VAS-A) were performed for investigating convergent validity. For test-retest reliability 30 people filled the RMDQ-Ro after 3–14 days later as recommended. Test-rest reliability was assessed with intra-class coefficient correlation (ICC). Non-parametric tests were employed due to the heterogeneity of the data. Therefore, the Spearman correlation test was used for determining the relationship between RMDQ-Ro and VAS-R and VAS-A.
Results The characteristics of the participants were shown at Table 1. The test-retest reliability of RMDQ-Ro was found at an excellent level (ICC: 0.95). Moderate positive correlations were determined between RMDQ-Ro and NRS-R (rho: 0.518, p<0.001), and NRS-A (rho: 0.484, p<0.001).
Conclusions RMDQ-Ro was found reliable regarding test-retest reliability. This questionnaire can be performed in the repeated measures for evaluating low back pain patients. However, more psychometric characteristics of RMDQ-Ro such as internal consistency and construct validity should be investigated in further studies.
