Roland-Morris Disability Questionnaire(RDQ)is a scale that allows the patients themselves to assess the degree of disability experienced during daily activities as a result of low back pain. There are 24 items that ask about the degree of disability experienced during daily activities such as standing, walking, sitting, getting dressed, and working. Each item in the RDQ can be answered with either"Yes" or "No", and the number of "Yes" results the RDQ score. The RDQ Japanese version was reported to have sufficient psychometric properties. Strength of this scale is their feasibility and interpretability (i.e. RDQ has Japanese norm score) . Limitation of this scale is insufficient accuracy due to few items. It is important to select the scale on the intended use in consideration of the above properties.
