Validation of the Hungarian version of the Roland–Morris disability questionnaire

Abstract

Translation and cross-cultural adaptation process of the RMQ into Hungarian language was successful resulting in a reliable and valid measurement tool with good psychometric properties. Implications for Rehabilitation Low back pain (LBP) related disability is a big health, social and economical problem in industrial countries. Correct evaluation of spine related disability can be performed using valid and reliable national versions of condition specific patient reported questionnaires such as the Roland-Morris Disability Questionnaire (RMQ). After the cross-cultural adaptation and validation of the Hungarian RMQ, it can be reliably used for the evaluation of LBP patients and for their follow-up during a rehabilitation process.

Translation, Cross-cultural Adaptation and Psychometric Evaluation of the Hausa Roland-Morris Disability Questionnaire in Mixed Rural and Urban Nigerian Populations with Low Back Pain

“…These modifications were similar to those done for the Igbo 33 and Yoruba 34 versions adapted to Nigerians. In line with other adaptations, 18,19,30,33 the questionnaire was wellunderstood and generally acceptable. Similarly, no floor neither ceiling effects were detected consistent with the literature.…”

“…41 Although this result suggests good internal consistency, previous adaptations, however, illustrate higher Cronbach's a ranging 0.82 to 0.96. 15,16,18,19,21,24,[28][29][30] Our ICC (0.79; 14-day retest) is somewhat comparable with both the original measure (ICC ¼ 0.88, 7-day retest), 41 and other language validations (ICC ¼ 0.72-0.87; >7-day retest). 17,29,33 Higher ICC values !0.90 were often reported by studies using an interval of 7-day retest.…”

“…Similarly, no floor neither ceiling effects were detected consistent with the literature. 19,25,33,34 The absence of floor and ceiling effects suggest that the Hausa-RMDQ may be able to distinguish respondents with the lowest or highest possible score, thus enhancing the reliability of the questionnaire. 39 The Cronbach's a of Hausa-RMDQ (0.70) was adequate considering the range of 0.70-0.90 recommended by Roland and Fairbank.…”

“…Our calculated, SEM (1.30) and MDC (3.60) were minimal and consistent with the German version (SEM ¼ 1.30, MDC ¼ 4.00), 45 and lower than the English version (SEM ¼ 1.79, MDC ¼ 5.00) 46 and other language versions (range: SEM ¼ 1.71-253, MDC ¼ 4.74-7.01). 19,33 The MDC indicates the range in which true change has occurred beyond measurement error. 39,47 Generally, a smaller MDC suggests a more sensitive measure.…”

“…13 For these reasons, the RMDQ has been translated and adapted into more than 50 languages/cultures 14 with variable degree of satisfactory psychometric and clinimetric properties. [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] Nigeria is the most populous country in Africa, with three major native languages: Hausa, Igbo, and Yoruba. Although English is the official language of the country, most patients cannot speak, read, or write in this language 9 possibly for the fact that many people live in rural areas with low levels of education.…”
