“…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.…”

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 <0.01). Subgroup analysis showed a higher effect size when using the specific questionnaire SarQoL compared with generic questionnaires (SMD −1.09; 95% CI −1.44; −0.74 with the SarQoL versus −0.49; 95% CI −0.63; −0.36 with generic tools; P‐value for interaction <0.01). A greater difference of HRQoL between sarcopenic and non‐sarcopenic was found for individuals residing in care homes compared with community‐dwelling individuals (P‐value for interaction <0.001). No differences were found between age groups, diagnostic techniques, and continents/regions. The level of evidence was rated as moderate using the GRADE assessment. This systematic review and meta‐analysis combining 43 observational studies shows that HRQoL is significantly reduced in sarcopenic patients. The use of disease‐specific HRQoL instruments may better discriminate sarcopenic patients with respect to their quality of life.

“…The COSMIN guideline required both patient and professional inputs to ensure the content validity of a PROM. Mahmoodi et al recently performed a content validity analysis with geriatric experts and reported an acceptable and appropriate content validity of SarQoL [ 8 ]. However, this study did not fill all the COSMIN criteria for the content validity of a PROM.…”

“…Nevertheless, concerning the content validity itself, COSMIN methodology requires to evaluated criteria encompassing 3 major aspects: relevance, comprehensibility and comprehensiveness in patients and experts [ 5 ]. To date, only one study has conducted a content validity analysis per se of SarQoL [ 8 ]. While the results of this study highlighted an adequate and acceptable content validity, this study was based solely on professionals’ opinions without fulfilling all the COSMIN criteria and without any patient involvement, leaving the content validity of SarQoL not entirely confirmed according to the COSMIN criteria [ 7 ].…”

Background The Sarcopenia & Quality of Life (SarQoL) questionnaire is a patient-reported outcome measure designed for assessing health-related quality of life in individuals with sarcopenia. Despite its wide acceptance in the scientific literature, its content validity has only been partially demonstrated so far. Aims To enhance the evidence supporting the content validity of the SarQoL questionnaire. Methods Following COSMIN methodology, semi-structured interviews were conducted with 17 Belgian older adults who met the EWGSOP2 criteria for the diagnosis of sarcopenia and 11 experts in sarcopenia, with clinical or research background. Comprehensiveness, relevance and comprehensibility of SarQoL content were assessed through individual transcripts and were qualitatively analyzed thematically according to the seven dimensions of SarQoL. Results The majority of the concepts elicited during the semi-structured interviews fitted within existing SarQoL dimensions. Importantly, the different domains of SarQoL were consensually considered as relevant by patients and experts. Some new emergent concepts were identified by the participants. While many of them could be considered as enrichments of existing dimensions or sub-concepts, other new concepts (i.e. self-fulfilment, acceptance of the reduced condition, adaptation/use of strategies, depression) may highlight two potential dimensions not covered by SarQoL, i.e. patient empowerment and depression. Cognitive interviews also highlighted that SarQoL items and instructions were clear and comprehensible. Conclusions SarQoL, in its current form, demonstrates good evidence of content validity for assessing health-related quality of life in patients with sarcopenia. We do not recommend adding new items or dimensions to SarQoL. Instead, for researchers or clinicians who aim to specifically address self-empowerment or depression of sarcopenic populations, we suggest completing the assessment of quality of life by concurrently using additional validated scales of patient empowerment or depression.

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.…”

BackgroundSarcopenia 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.MethodsThis 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.ResultsFifty‐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]).ConclusionsThe 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.
