ABSTRACT
Background:
The evaluation of disability is highly relevant for the study and clinical follow-up of pain. Reliable and culturally valid instruments are required for this purpose.Aim:
To adapt and to validate the Roland-Morris Disability Questionnaire (RDQ) to measure disability in low back pain Chilean patients and to study the psychometric properties of an abbreviated six item version of this instrument. Material andMethods:
The instrument’s original version was translated and back translated into Spanish, and specialists ensured the cultural validation to Chile. Disability mental health using the Goldberg General Health Questionnaire (GHQ-12) and pain using a visual analogue scale (VAS) were evaluated in 206 patients, during a medical appointment due to acute low back pain.Results:
The Chilean version of the original 24-item RDQ and the new six item version showed adequate internal consistency. The short version also showed a good convergent validity. It had the same pattern of correlations with VAS and GHQ-12 scales, as the original 24 item scale. Greater disability was associated with higher pain intensity and poorer mental health. The construct validity analysis identified one factor, for both versions of the RDQ.Conclusions:
The adapted Chilean version of the original RDQ is a reliable and valid questionnaire, as well as the new abbreviated six items version, which showed adequate psychometric properties.
