[en] OBJECTIVES: To translate the Sarcopenia Quality of Life (SarQoL®) questionnaire into Dutch and to evaluate the psychometric properties of the Dutch version of this questionnaire. METHODS: The translation was carried out using a 5-step process, with 2 initial translations, a merging of these 2 translations, 2 backwards translations, an expert committee review and a pretest of the questionnaire. Sarcopenia was diagnosed with the EWGSOP algorithm. The validation consisted of an examination of the discriminative power, internal consistency, construct validity, test-retest reliability and floor and ceiling effects. RESULTS: No significant problems were encountered during the translation process. A total of 92 subjects were included in the validation part of this study, 30 of which were sarcopenic. Discriminative power between sarcopenic and nonsarcopenic subjects was found for all domains and the Overall score (median overall QoL score: 67.15 vs 79.72; p=0.003). High internal consistency was found (Cronbach’s alpha=0.883), as well as good construct validity with 75% of hypotheses confirmed. Test-retest reliability was excellent (ICC=0.976; 95% CI=0.947-0.989) and no floor or ceiling effects were observed. CONCLUSION: The Dutch version of the SarQoL® questionnaire is ready for use in clinical and research applications.
