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.
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.
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.
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.
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.
残疾评估对于疼痛的研究和临床随访具有高度相关性。为此需要可靠且具有文化效度的工具。
对罗兰 - 莫里斯残疾问卷（RDQ）进行改编和验证，以测量智利下背痛患者的残疾情况，并研究该工具简化后的六项版本的心理测量特性。
该工具的原始版本被翻译并回译为西班牙语，专家确保其在智利具有文化效度。在206例因急性下背痛就诊的患者中，使用戈德堡一般健康问卷（GHQ - 12）评估残疾心理健康状况，使用视觉模拟量表（VAS）评估疼痛情况。
原始24项RDQ的智利版本和新的六项版本显示出足够的内部一致性。简短版本也显示出良好的收敛效度。它与VAS和GHQ - 12量表的相关性模式与原始24项量表相同。更大的残疾与更高的疼痛强度和更差的心理健康状况相关。结构效度分析为两个版本的RDQ都确定了一个因素。
改编后的智利版原始RDQ以及新的简化六项版本都是可靠且有效的问卷，显示出足够的心理测量特性。
