To precisely evaluate the disability resulting from low back pain and the efficacy of interventions, it is essential to utilize a standardized instrument capable of measuring the patient's condition changes over time. One of the most frequently utilized self-administered standardized questionnaires is the Roland Morris Disability Questionnaire (RMDQ).
To culturally adapt the RMDQ into Albanian and assess its psychometric properties within an Albanian population.
OBSERVATIONAL: Patient sample: The total sample consisted of 200 individuals diagnosed with various conditions including persistent low back pain, coxofemoral luxation, back trauma, lumbar fracture, and arthritis. Outcome measures: The RMQ consists of 24 individual items each presented as a single sentence. The maximum achievable score is 24, while the minimum is 0.
The research procedure involved two phases: initially, the translation and cultural adaptation, and subsequently, the assessment of quality within a clinical investigation. Test-retest reliability at 7 days was evaluated in 200 participants.
Kappa statistics showed that Alb-RMDQ had acceptable item-by-item agreement for 11 items (k = 0.603-0.755) and the remaining 13 were moderate agreement (k = 0.464-0.595). The exploratory factor analysis (EFA) of Albanian version was used to determine this dimensionality. An initial EFA analysis with a principal component analysis using Varimax with Kaiser Normalization rotation method resulted in a 10-factor structure with a KMO = 0.465 and a Chi-square = 461.791, p = 0.000. The Interclass Correlation Coefficient (ICC) between the first and the second evaluation for each item performed with two mixed effect model was between 0.621-0.938 using an absolute agreement definition.
The AlbRMDQ version of RMDQ has a good validity and reliability and may be an important outcome tool for the clinical and research purpose for the Albanian speaking population.
为了精确评估下腰痛导致的残疾情况以及干预措施的疗效，使用一种能够测量患者病情随时间变化的标准化工具至关重要。罗兰·莫里斯残疾问卷（RMDQ）是最常用的自我管理标准化问卷之一。
将RMDQ进行文化适应，使其适用于阿尔巴尼亚语，并在阿尔巴尼亚人群中评估其心理测量特性。
观察性研究：患者样本：总样本包括200名被诊断患有各种疾病的个体，这些疾病包括持续性下腰痛、髋脱位、背部创伤、腰椎骨折和关节炎。结果测量：RMQ由24个单独项目组成，每个项目以单句形式呈现。最高可得分为24分，最低分为0分。
研究过程包括两个阶段：首先是翻译和文化适应，随后是在临床研究中评估质量。对200名参与者进行了7天的重测信度评估。
卡方统计显示，阿尔巴尼亚语版RMDQ（Alb-RMDQ）的11个项目具有可接受的逐项一致性（k = 0.603 - 0.755），其余13个项目为中等一致性（k = 0.464 - 0.595）。使用阿尔巴尼亚语版的探索性因子分析（EFA）来确定维度。最初的EFA分析采用主成分分析，使用带有Kaiser正态化旋转方法的Varimax，得到了一个10因子结构，KMO = 0.465，卡方 = 461.791，p = 0.000。使用绝对一致性定义，每个项目的第一次和第二次评估之间的组内相关系数（ICC）在0.621 - 0.938之间。
RMDQ的阿尔巴尼亚语版（AlbRMDQ）具有良好的效度和信度，可能是阿尔巴尼亚语人群临床和研究目的的重要结果工具。
