Cross cultural adaptation of the Greek sarcopenia quality of life (SarQoL) questionnaire

Cross-sectional Evaluation of the Sarcopenia Quality of Life (SarQoL) Questionnaire: Translation and Validation of its Psychometric Properties

“…www.e-agmr.org low number of study population. Similar publications of validations of the SarQoL are available for the English, French, Dutch, Romanian, Polish, Lithuanian, Greek, and other language versions, [7][8][9][10]13,25) with similar results in terms of the reliability and validity of the SarQoL questionnaire.…”

“…The questionnaire was initially developed and validated in French in 2015 5,6) and was later translated and validated into English, Dutch, Romanian, Polish, Hungarian, Russian, and Greek. [7][8][9][10][11][12][13] To provide the Ukrainian nation with a qualitative and reliable questionnaire to measure the quality of life of sarcopenic patients, we have created the Ukrainian version of the SarQoL questionnaire. The process of translation and validation followed the protocol for translation provided by the authors of the SarQoL questionnaire, which were based on the recommendations of Beaton et al 14) This protocol included translation, cross-cultural adaptation, and validation of psychometric properties of the questionnaire.…”

Standard error of measurement and smallest detectable change of the Sarcopenia Quality of Life (SarQoL) questionnaire: An analysis of subjects from 9 validation studies

“…These 6 studies found that the questionnaire can discriminate between sarcopenic and non-sarcopenic participants, with the former having significantly lower scores for the 7 domains and the overall score, and that the questionnaire possesses good internal consistency (Cronbach's alpha of 0.87, 0.88, 0.95, 0.92, 0.88 and 0.96). These studies also confirmed the construct validity of the SarQoL questionnaire with the help of hypotheses on correlations between the questionnaire and the SF-36 and EQ-5D, and demonstrated that the SarQoL questionnaire has an excellent test-retest reliability (intraclass correlation coefficient/ICC = 0.91, 0.95, 0.99, 0.98 and 0.96) [9][10][11][12][13][14]. Lastly, floor and ceiling effects were absent from all 6 published validation studies [9][10][11][12][13][14].…”

Lastly, floor and ceiling effects were absent from all 6 published validation studies [9][10][11][12][13][14]. These results provide convincing evidence for the validity and reliability of the SarQoL questionnaire for the evaluation of quality of life in sarcopenic, community-dwelling older people.…”

“…The psychometric properties of the SarQoL questionnaire have been evaluated and published for 6 language-versions: the original questionnaire in French, and the English, Dutch, Polish, Romanian and Greek translations [9][10][11][12][13][14]. These examined the discriminative power, internal consistency, construct validity, test-retest reliability and the presence of floor or ceiling effects.…”
