Background
The German version of the SarQoL®, a sarcopenia-specific quality of life (QoL) questionnaire, has not been validated hindering its widespread use. This study aimed to evaluate the psychometric properties of the German SarQoL®.
Methods
Via a cross-sectional study participants were recruited in two geriatric outpatient facilities and one acute geriatric ward in Munich (Germany). Sarcopenia and probable sarcopenia were diagnosed with the European Working Group on Sarcopenia in Older People (EWGSOP2) algorithm. From 185 participants (age 79.8 ± 6.1), 77 had probable sarcopenia, and 51 had sarcopenia. Participants completed the SarQoL® and the European Quality-of-Life 5-Dimension (EQ-5D) questionnaires. The validation included examination of the discriminative power, construct validity, internal consistency, test-retest reliability, and floor/ceiling effects.
Results
Lower SarQoL®scores for sarcopenic (p = 0.002) and probable sarcopenic subjects (p < 0.001) compared to controls indicated good discriminative power. Consistent construct validity was found for sarcopenic subjects: moderate to high correlations with domains capturing similar constructs of the EQ-5D: ‘Activities of daily living’ (r = -0.58, p < 0.001), ‘Mobility’ (r = -0.72, p < 0.001) and low correlations with domains related to different constructs like ‘Pain’ (r = -0.32, p < 0.022). Similar correlations were found for probable sarcopenic subjects. The Cronbach’s alpha was 0.8. Test-retest reliability was excellent (intraclass coefficient correlation of = 0.96; 95% CI = 0.91–0.99), and no floor/ceiling effects were observed.
Conclusion
QoL was similarly reduced in both patient cohorts compared to controls. The German SarQoL® is a valid and reliable instrument for measuring QoL in patients > 65 years of age with sarcopenia and probable sarcopenia and can now be used in epidemiological studies and clinical trials in a German-speaking population.

... However, the cultural and lifestyle factors unique to this population necessitate localized validation of screening tools such as the SarQoL ® questionnaire. Previous studies have validated the SarQoL-K and demonstrated its applicability in the Korean context [23]. Building on this foundation, the present study sought to further refine the use of the SarQoL ® questionnaire by identifying a specific cutoff point that can effectively identify individuals with sarcopenia among community-dwelling Korean older adults. ...
... Higher scores indicate better QoL. This version of the SarQoL ® questionnaire was used to assess an overall QoL, which was scored from 0 to 100 points based on the questionnaire responses [23,28]. The overall QoL score was calculated using a specialized MS Access database developed specifically for this purpose and can be obtained upon request. ...
Background/objectives: Sarcopenia, characterized by the progressive loss of muscle mass and strength, poses significant risks to physical health, leading to a reduced quality of life (QoL), increased disability, and higher mortality rates among older adults. Early detection and intervention are crucial to prevent the cascading effects of sarcopenia, including falls, fractures, and hospitalization. This study determined an optimal cut-off point of the SarQoL® score that can serve as an effective screening tool among community-dwelling Korean older adults. Methods: The study involved 451 South Korean older adults, assessing the correlation between SarQoL® scores and sarcopenia as defined by the Asian Working Group for Sarcopenia (AWGS) criteria. Participants completed the Korean version of the SarQoL questionnaire. Results: Findings revealed that individuals diagnosed with sarcopenia had significantly lower SarQoL® scores compared to non-sarcopenic participants, with a cut-off score of ≤58.5 providing good diagnostic accuracy (AUC = 0.768, sensitivity = 69.3%, specificity = 75.2%). Conclusions: These results underscore the questionnaire’s reliability and validity in screening for sarcopenia-related QoL impairment and its potential utility as a clinical tool. Implementing the SarQoL® in routine assessments could improve clinical outcomes by enabling earlier and more precise identification of sarcopenia.
... Beaudart et al. 19,20 developed and validated Sarcopenia Quality of Life (SarQoL®, www.sarqol.org), a 22-question self-reported sarcopenia-specific questionnaire. SarQoL® has been translated and validated in several languages, [21][22][23][24][25][26][27][28][29] showing proof of a valid and reliable questionnaire for measuring QoL in the sarcopenic population. ...
... However, no correlations were found between the overall SarQol® Indonesia score to SF-36 bodily pain, SF-36 vitality, and EQ-VAS. Despite other validation studies [21][22][23]25,26,29 including EQ-5D self-care in convergent validity, we hypothesized that EQ-5D self-care theoretically should correlate well with SarQol® Indonesia based on several studies that showed lower self-care ability in sarcopenic subjects. 17,18 On the other hand, for divergent construct validity, no correlations were found in all the hypothesized parameters (SF-36 social functioning, SF-36 role limitation due to emotional problems, SF-36 mental health, EQ-5D pain/ discomfort, and EQ-5D anxiety/depression). ...
Background
Sarcopenia significantly impairs quality of life (QoL). The Sarcopenia Quality of Life® (SarQol®) questionnaire provides a sarcopenia‐specific instrument for the assessment of QoL. The aim of this study was to cross‐culturally adapt the SarQol® to an Indonesian language questionnaire and to confirm its validity and reliability as a tool to measure QoL in Indonesian‐speaking elderly patients with sarcopenia.
Methods
This cross‐sectional study translated and cross‐culturally adapted the SarQol® questionnaire, followed by evaluating the psychometric properties of the final cross‐culturally adapted SarQol® Indonesia questionnaire.
Results
Fifty‐nine elderly Indonesian subjects (29 sarcopenic and 30 nonsarcopenic) with a mean age of 72.2 ± 6.3 years were included in this study. SarQol® Indonesia questionnaire overall provides a good discriminative value [60.61 ± 14.34 vs. 73.60 ± 13.17, p = 0.001], good internal consistency (Cronbach's ⍺ coefficient = 0.896 and McDonald's ⍵ coefficient = 0.906, both with good correlation to the questionnaire individual domains), acceptable construct validity, and good test–retest reliability (intraclass correlation coefficient: 0.962 [95% confidence interval: 0.883–0.987]).
Conclusions
The SarQol® Indonesia questionnaire provides a conceptual and literally equivalent questionnaire content to its original source with good discriminative value, good internal consistency, acceptable construct validity, and good test–retest reliability. The SarQol® Indonesia questionnaire is ready to be used to measure QoL in Indonesian elderly sarcopenic individuals.
... The SarQoL-K questionnaire comprises twenty-two scaled questions and assesses the quality of life in community-dwelling elderly individuals aged 65 years and older who have sarcopenia. The questionnaire has been translated and validated in Korean [26] with scores ranging from 0 to 100. ...
Background
Osteosarcopenia is geriatric syndrome defined as the concomitant occurrence of osteopenia/osteoporosis, and sarcopenia. Osteosarcopenia is a relatively new concept in geriatric medicine; however, it may increase the risk of fragility fractures, several morbidities and mortalities, and socioeconomic costs. Although resistance exercises and nutritional support—including protein, calcium, and vitamin D—are potential non-pharmacological management procedures, evidence is still lacking. The objective of this study was therefore to evaluate the effect of combined resistance exercise and nutritional support on the quality and quantity of bone and muscle in postmenopausal females with osteosarcopenia.
Methods
This research proposal presents the protocol for a prospective, single-center, single-blinded, two-armed randomized controlled trial. Thirty-four participants with osteosarcopenia will be recruited and randomly divided into intervention and control groups; both groups will receive nutritional supplements (protein, 40 g; vitamin D, 1600 IU; calcium, 600 mg) daily. The intervention group will undergo 24 weeks of resistance exercise of increasing intensity, achieved through a three-phase step-up process. The primary outcomes will be the changes in skeletal muscle index and bone marrow density of the lumbar spine and femoral neck between the baseline and end of intervention (24 weeks). The secondary outcomes will be the body composition, whole body phase angle, physical function assessment, quality of life, psychological assessment, and bone turnover markers of participants, surveyed at multiple time points.
Discussion
This randomized controlled trial may reveal the effect of resistance exercise and nutritional support on older postmenopausal women with osteosarcopenia. The results will provide evidence for developing proper non-pharmacological management guidelines for postmenopausal women.

... Regarding the ethnicity of participants, although the difference between groups was not significant, we still observed nevertheless a larger SMD for studies conducted in Asia or using the AWGS criteria for sarcopenia diagnoss. However, this association may be biased by the results of some outliers, such as Mahmoodi et al., 28 Lee et al., 66 Le et al. 54 and Yoo et al. 60 who reported larger SMD compared with other studies. Sensitivity analyses revealed that these individual studies did not impact the global estimated effect size. ...
Abstract The decrease of physical abilities and functional decline that can be caused by musculoskeletal conditions such as sarcopenia, can lead to higher levels of dependency and disability. Therefore, it may influence patient reported outcome measures (PROM), such as the health‐related quality of life (HRQoL). The purpose of this systematic review and meta‐analysis is to provide a comprehensive overview of the relationship between sarcopenia and HRQoL. Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) were followed throughout the whole process of this work. A protocol was previously published on PROSPERO. The electronic databases MEDLINE, Scopus, Allied and Complementary Medicine (AMED), EMB Review – ACP Journal Club, EBM Review ‐ Cochrane Central of Register of Controlled Trials and APA PsychInfo were searched until October 2022 for observational studies reporting a HRQoL assessment in both sarcopenic and non‐sarcopenic individuals. Study selection and data extraction were carried out by two independent researchers. Meta‐analysis was performed using a random effect model, reporting an overall standardized mean difference (SMD) and its 95% confidence interval (CI) between sarcopenic and non‐sarcopenic individuals. Study quality was measured using the Newcastle‐Ottawa Scale and the strength of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) tool. The search strategy identified 3725 references from which 43 observational studies were eligible and included in this meta‐synthesis study. A significantly lower HRQoL was observed for sarcopenic individuals compared with non‐sarcopenic ones (SMD −0.76; 95% CI −0.95; −0.57). Significant heterogeneity was associated with the model (I2 = 93%, Q test P‐value
... Till date, the questionnaire has been translated to 30 languages and made available on the internet at www. sarqol.org. Furthermore, the English, Romanian, Dutch, Polish, Hungarian, Lithuanian, Russian, Greek, Ukranian, Serbian, Spanish, Korean, Chinese, and Turkish versions have been validated and its psychometric properties evaluated [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41]. ...
... The internal consistency of the Hungarian version of the SarQoL questionnaire administered in our cohort was of high level and there was a statistically significant correlation between the overall and individual domain scores. This is in tally with all the previously published validation studies [25][26][27][28][29][31][32][33][34][35][36][37][38][39][40][41]. ...
Background
Sarcopenia is defined as an age-related progressive and systemic loss of muscle mass and function. World Health Organization (WHO) definition of health-related quality of life (QoL) states that health is considered “a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity”, and a decline in QoL is anticipated in individuals with sarcopenia. Beaudart et al. framed the concept of defining QoL in patients suffering from sarcopenia (SarQoL) based on fundamental procedures of QoL questionnaire development, expert recommendations and studies. The aim of the present study is to evaluate the discriminative power, internal consistency and floor and ceiling effects using data available from a sarcopenia study published recently, where the Hungarian version of the SarQoL questionnaire was also administered.
Methods
In this cross-sectional study, data from SarQoL questionnaire administered to a postmenopausal sarcopenia study cohort (n = 100) was scrutinized for evaluation of psychometric properties of the questionnaire. Our verification of the psychometric properties consisted of discriminative power analysis, assessment of internal consistency, and floor and ceiling effects. The homogeneity of the SarQoL questionnaire, i.e., its internal consistency was measured using Cronbach’s alpha coefficient. Correlation between the overall and domain SarQoL questionnaire scores and appendicular skeletal muscle mass in sarcopenic individuals was assessed. Furthermore, the difference of SarQoL overall and domain scores between sarcopenic and non-sarcopenic patients was also evaluated.
Results
The median (interquartile range (IQR)) overall SarQoL questionnaire score was 81.5 (67.1–91.5). There was a statistically significant lower overall SarQoL score comparing sarcopenic and non-sarcopenic subjects median (IQR): 75.3 (62.1–86.3) vs. 83.7 (71.4–92.1); p = 0.041). The sarcopenic subjects showed a statistically significant (p = 0.021) correlation between the overall SarQoL score and appendicular skeletal muscle mass (Spearman’s ϱ = 0.412). The overall Cronbach’s alpha of 0.937 indicated a high internal consistency of the Hungarian version of the SarQoL questionnaire. No floor or ceiling effects were noted in the overall SarQoL questionnaire score.
Conclusion
In our study on community dwelling outpatient postmenopausal Hungarian women, the overall score of the Hungarian version of the SarQoL questionnaire had significant discriminative power to distinguish between sarcopenic and non-sarcopenic patients, had high internal consistency and no floor or ceiling effects.
... The proportion of older adults in Korea has increased from 15.7% in 2020 to 16.5% in 2021 and is expected to rise to 20.3% by 2025 [1]. Sarcopenia progresses with age, wherein grip strength and muscle mass decrease due to physiological changes in the body [2,3]. With an increasingly aging population, it is estimated that approximately 700,000~1 million older adults in Korea will suffer from sarcopenia [4]. ...
... The QoL of older adults with sarcopenia is much lower than that of older adults without sarcopenia [10]. Moreover, older adults with symptoms of sarcopenia have lower QoL in the areas of physical and mental health, exercise, body composition, activities of daily living, and decreased strength and muscle mass [2]. Older women who have had a fall and have been diagnosed with sarcopenia tend to have reduced QoL [11]. ...
... QoL of LOAs with sarcopenia in this study was low, possibly due to low income, lack of surrounding resources, and lack of support systems. In a cohort study of older adults in Korea, muscle strength loss was highly correlated with physical function decline after five years [2], thereby reducing QoL and leading to mortality [4]. Thus, efforts are needed to improve the QoL of LOAs with sarcopenia. ...
Purpose:
This study aimed to identify the factors influencing quality of life (QoL) of low-income older adults (LOAs) with sarcopenia.
Methods:
A convenience sample of 125 older adults was recruited from Jeonbuk Province, South Korea. Data were collected using a self-report questionnaire that included nutritional status, the Depression Anxiety Stress Scale-21, and the World Health Organization Quality of Life Instrument-Older Adults Module. Additionally, grip strength and appendicular skeletal muscle mass, were evaluated, along with the short physical performance battery.
Results:
Sarcopenia and severe sarcopenia were observed in 43.2% and 56.8% of participants, respectively. Using multiple regression analysis, depression (β = -.40, p < .001), nutritional status (β = .24, p = .003), and anxiety (β = -.15, p = .042) were identified as factors affecting the QoL of the older adults in low-income groups with sarcopenia, the explanatory power of these variables was 44%.
Conclusion:
The results of this study can be used to develop a nursing intervention program and establish policies to improve depression, anxiety, and nutritional status to enhance QoL of LOAs with sarcopenia.
... Therefore, it is advocated that a thorough evaluation should be performed for older adults with sarcopenia to provide complete information about the quality of life of patients [11][12][13]. In this regard, it is necessary to evaluate the quality of life in these patients through appropriate tools [13,14]. ...
... Therefore, it is advocated that a thorough evaluation should be performed for older adults with sarcopenia to provide complete information about the quality of life of patients [11][12][13]. In this regard, it is necessary to evaluate the quality of life in these patients through appropriate tools [13,14]. Although two questionnaires (SF-36 and EQ-5D) are commonly used to assess the quality of life in all individuals, these two questionnaires do not cover all of the physical disorders associated with sarcopenia. ...
... In accordance with previously published SarQoL ® validation studies [13,15,31], the quality of life was assessed using SF-36 and EQ-5D questionnaires, which were supposed to have similar dimensions (convergent validity) or different dimensions (divergent validity). Therefore, sarcopenic patients should also fill three questionnaires. ...
Background
The sarcopenia quality of life (SarQoL)® questionnaire is a specific tool to measure QoL in sarcopenia. The aim of this study was to validate the SarQoL® questionnaire for evaluation of sarcopenia-related quality of life in Iranian community-dwelling older adults.Methods
Validity (discriminative power, construct validity), reliability (internal consistency, test–retest reliability), and floor/ceiling effects of SarQoL® questionnaire were evaluated in the current study. Moreover, the SarQoL® questionnaire was compared with the Short-Form 36-item (SF-36) and the EuroQoL 5-Dimensions (EQ-5D) questionnaires.ResultsAmong 501 community-dwelling older adults, 128 elderly participants (including 88 sarcopenic individuals) were recruited for validation. Participants with sarcopenia had lower quality of life than non-sarcopenic individuals (Total Score: 39.37 ± 7.45 vs. 65.09 ± 7.85, p < 0.001). Also, the findings demonstrated a high internal consistency (Cronbach’s alpha of 0.881), excellent test–retest reliability (ICC = 0.995, 95% CI 0.990–0.998), and no floor/ceiling effect of SarQoL® questionnaire.Conclusion
This is the first study to confirm the reliability and validity of the Persian version of the SarQoL® for the measurement of quality of life among Iranian sarcopenic older adults.
... The Sarcopenia Quality-of-Life (SarQoL) questionnaire, the first disease-specific questionnaire for sarcopenia, was first developed and validated in French 10 and has since been translated into and validated in various languages, including English, 11 Korean, 12 Croatian, 13 and Greek. 14 Previous validated studies showed the consistent results that the SarQoL questionnaire has favorable validity and reliability such as good discriminative power, high internal consistency, consistent construct validity and excellent test-retest reliability. ...
Background
The Sarcopenia Quality of Life (SarQoL) questionnaire has been translated into various languages. This study validated the Taiwanese version of the SarQoL (SarQoL-TW) questionnaire.
Methods
Forward–backward translation was conducted, along with a test of the prefinal version of the translated questionnaire. To validate the psychometric properties of the questionnaire, 50 older adults with sarcopenia and 50 older adults without sarcopenia completed the SarQoL-TW, the Short Form12 Health Survey (SF-12), and the EQ-5D-3L questionnaire. Participants with sarcopenia were asked to complete the SarQoL-TW questionnaire once more after 2 weeks. Validating the psychometric properties of the SarQoL-TW questionnaire involved assessing its discriminative power, internal consistency, construct validity, test–retest reliability, and potential floor and ceiling effects.
Results
The SarQoL-TW questionnaire was translated without major difficulties. The psychometric analysis revealed that older adults with sarcopenia scored significantly lower on the SarQoL-TW, both overall and in some of the domains. The Cronbach's alpha of 0.846 indicated high internal consistency. The SarQoL-TW questionnaire correlated well with similar constructs on the SF-12 and EQ-5D-3L for convergent validity and correlated weakly with distinct domains for divergent validity, confirming its favorable construct validity. The test–retest reliability was excellent (intraclass correlation coefficient: 0.970). Neither floor nor ceiling effects were observed.
Conclusion
The SarQoL-TW questionnaire is a reliable and valid questionnaire, useful for assessing quality of life in older adults with sarcopenia in clinical practice and research.
... After reading the titles and applying the selection criteria to all the documents, a total of 14 cross-cultural adaptations were selected [5,13,14,[22][23][24][25][26][27][28][29][30][31][32] in different languages, such as English, Romanian, Dutch, Polish, Greek, Lithuanian, Russian, Spanish, Ukrainian, Korean, Serbian, Chinese, and Turkish. The Hungarian version was not considered as the validation phase of the questionnaire had not been carried out. ...
... Finally, we had a total of 14 articles left for carrying out this systematic review; this entire selection process is shown in the flowchart below ( Figure 1). After reading the titles and applying the selection criteria to all the documents, a total of 14 cross-cultural adaptations were selected [5,13,14,[22][23][24][25][26][27][28][29][30][31][32] in different languages, such as English, Romanian, Dutch, Polish, Greek, Lithuanian, Russian, Spanish, Ukrainian, Korean, Serbian, Chinese, and Turkish. The Hungarian version was not considered as the validation phase of the questionnaire had not been carried out. ...
... To evaluate the validity of the content in the 13 versions of the SarQoL ® , the three criteria considered in the COSMIN guidelines were taken into account [34], including relevance, comprehensiveness, and comprehensibility. Twelve out of the thirteen studies analyzed the validity of the content, and six of them [23,24,26,[29][30][31] considered the comprehensibility criterion. The validity of the content could not be evaluated because these aspects were doubtful or unclear, and so were considered as inconsistent. ...
Background:
Sarcopenia is the gradual and global loss of muscle and its functions. Primary sarcopenia is associated with the typical changes of advanced aging and affects approximately 5-10% of the population. The Sarcopenia and Quality of Life (SarQoL®) questionnaire is composed of 55 items, 22 questions, and is organized into seven domains of quality of life. The main objective of this systematic review was to analyze the structural characteristics and psychometric properties of it, as well as to classify its measurement properties, its methodological quality, and the criteria as good measurement properties of the adaptations and validations made on the SarQoL® questionnaire in different languages.
Methods:
A systematic review was carried out in the PUBMED, Web of Science, Cinahl, LatinIndex, and SCOPUS databases. The keywords used were: "SarQoL", "assessment", "sarcopenia", "geriatric", "PROM", "quality of life", and "questionnaire", using the Boolean operator "AND". All articles published up to 15 January 2022 were considered. Methodological quality and psychometric properties were assessed based on the COSMIN guidelines and the guidelines and general recommendations of PRISMA. Documents published in languages other than English were excluded, as well as versions of the SarQoL® published in the form abstracts for conferences when the full text was not available.
Results:
A total of 133 articles were identified, 14 of which were included. The evaluated questionnaires and the structural characteristics and psychometric properties of each of them were collected.
Conclusion:
The different cross-cultural versions of the questionnaire showed good basic structural and psychometric characteristics for the evaluation of patients with sarcopenia.
