Translation, cross-cultural adaptation, validity and reliability of the inaugural Albanian Roland-Morris Disability Questionnaire in Albanian population with low back pain.
Observational study in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
background contextTo 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). PURPOSE: To culturally adapt the RMDQ into Albanian and assess its psychometric properties within an Albanian population. STUDY
designOBSERVATIONAL: 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.
methodsThe 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.
resultsKappa 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.
conclusionsThe 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.
