Quality Of Life Scale

This study aims to validate the Multiple Sclerosis (MS) International Quality of Life (MusiQoL) questionnaire, a multi-dimensional, self-administered questionnaire, available in 14 languages, as a disease-specific quality of life scale that can be applied internationally. A total of 1992 patients with different types and severities of MS from 15 countries were recruited. At baseline and day 21 ± 7, each patient completed the MusiQoL, a symptom checklist and the short-form (SF)-36 QoL questionnaire. Neurologists also collected socio-demographic, MS history and outcome data. The database was randomly divided into two subgroups and analysed according to different patient characteristics. For each model, psychometric properties were tested and the number of items was reduced by various statistical methods. Construct validity, internal consistency, reproducibility and external consistency were also tested. Nine dimensions, explaining 71% of the total variance, were isolated. Internal consistency and reproducibility were satisfactory for all the dimensions. External validity testing revealed that dimension scores correlated significantly with all SF-36 scores, but showed discriminant validity by gender, socio-economic and health status. Significant correlations were found between activity in daily life scores and clinical indices. These results demonstrate the validity and reliability of the MusiQoL as an international scale to evaluate QoL in patients with MS. Multiple Sclerosis 2008; 14: 219—230. http://msj.sagepub.com

Objective: To develop and validate a Thai version of the Wisconsin Quality of Life (TH WISQoL) Questionnaire. Materials and Methods: The authors developed the TH WISQoL Questionnaire based on a standard multi-step process. Subsequently, the authors recruited patients with kidney stone and requested them to complete the TH WISQoL and a validated Thai version of the 36-Item Short Form Survey (TH SF-36). The authors calculated the internal consistency and interdomain correlation of TH WISQoL and compared the convergent validity between the two instruments. Results: Thirty kidney stone patients completed the TH WISQoL and the TH SF-36. The TH WISQoL showed acceptable internal consistency for all domains (Cronbach’s alpha 0.768 to 0.909). Interdomain correlation was high for most domains (r=0.698 to 0.779), except for the correlation between Vitality and Disease domains, which showed a moderate correlation (r=0.575). For convergent validity, TH WISQoL demonstrated a good overall correlation to TH SF-36, (r=0.796, p<0.05). Conclusion: The TH WISQoL is valid and reliable for evaluating the quality of life of Thai patients with kidney stone. A further large-scale multi-center study is warranted to confirm its applicability in Thailand. Keywords: Quality of life, Kidney stone, Validation, Outcome measurement

Background: Neuromuscular disorders affect physical and mental aspects of a patient and in other words alter the patients’ quality of life (QOL). In the present study, we investigated the validity and reliability of the Persian version of Individualized Neuromuscular QOL (INQOL) to provide a better insight into patients’ QOL. Methods: Original version of the INQOL was translated backward and then forward. The resultant Persian version and a standard questionnaire, 36-Item Short Form Health Survey (SF-36), were then given to 83 participants with neuromuscular disorders. Internal consistency, known-group validity, concurrent validity, and test-retest reliability were assessed. Results: The scores of matched sections for QOL in the two questionnaires were favorably correlated (P < 0.05). Correlation between test and retest scores was also significant (P < 0.05). Moreover, the Cronbach’s alpha of 0.82 was representative of robust internal consistency between INQOL covering sections. Conclusion: The Persian version of the INQOL can be used in clinical and research practice to detect changes in QOL which are related to neuromuscular disorders, due to its favorably reliable and valid characteristics.

Disease Specific

Quality of life (QoL) is discussed as an additional outcome measure in multiple sclerosis (MS). However, few questionnaires assessing disease specific QoL in MS have been published. On the basis of the literature and interviews with clinicians and MS patients, we have developed a disease specific QoL instrument and validated it in a broad range of patients with MS. In this study, a heterogeneous sample of n=237 MS patients completed the newly developed Hamburg Quality of Life Questionnaire in Multiple Sclerosis (HAQUAMS, in German language) and a battery of already validated questionnaires. They further underwent neurological scoring and objective tests. By these means, we investigated its validity, appropriateness, internal consistency, and retest reliability. Internal consistency and retest coefficients were high and satisfied psychometric standards. Convergent and discriminant validity was supported by direction, magnitude and pattern of correlations with other health measures. HAQUAMS subscales and its total score distinguished between patient groups of varied disease severity, cognitive impairment, and affective symptomatology. No floor or ceiling effects were found in either of the HAQUAMS subscales. The HAQUAMS is a reliable, valid and appropriate instrument for QoL assessment in multiple sclerosis. Data of responsiveness are currently being obtained.

We assessed the functional impairment in Charcot-Marie-Tooth resulting from 17p11.2-p12 duplication (CMT1A) patients using the Short-Form Health Survey (SF-36), which is a quality of life questionnaire. Twenty-five patients of both genders aged ≥10 years with a positive molecular diagnosis of CMT1A were selected. Age- and gender-matched Control Group (without family history of neuropathy), and the sociodemographic and professional conditions similar to the patients' group were selected to compare the SF-36 results between them. The results showed that the majority quality of life impairments in CMT1A patients occurred in the social and emotional domains. Functional capacity also tended to be significantly affected; other indicators of physical impairment were preserved. In conclusion, social and emotional aspects are mostly neglected in the assistance provided to CMT1A Brazilian patients, and they should be better understood in order to offer global health assistance with adequate quality of life as a result.

L’obiettivo di questo lavoro è stato di valutare la storia naturale di crescita degli schwannomi vestibolari (VS), la qualità di vita di quelli trattati in maniera conservativa e di validare una scala specifica per tale malattia in lingua francese, Penn Acoustic Neuroma Quality-of- Life (PANQOL). Sono stati studiati retrospettivamente 26 pazienti con VS trattato in maniera conservativa. Sono state raccolte le caratteristiche dei pazienti e i reperti radiologici, e sono state utilizzate due scale per validare valutare la qualità di vita: la Short Form-36 Health Survey (SF-36) e la PANQOL scale, tradotta in francese. I punteggi ottenuti sono stati comparati con gli studi precedenti. Il tempo medio di follow up è stato di 25 mesi (range 6-72). È stata osservato un accrescimento del tumore in 14 pazienti (53,8%), nessun accrescimento in 12 pazienti (46,2%), e non si è verificata nessuna riduzione. La crescita media del tumore è stata di 2,22 mm/anno, e non sono stati individuati fattori predittivi di crescita. I pazienti con vertigini e instabilità hanno riferito una più bassa qualità di vita, sia secondo la scala SF-36, sia secondo la scala PANQOL. Utilizzando la scala SF-36, i nostri risultati si sono rivelati paragonabili a quelli della letteratura. Utilizzando la scala PANQOL, i nostri punteggi non si sono rivelati statisticamente diversi da quelli derivanti da studi tedeschi e nordamericani, ad eccezione di quelli riguardanti l’udito (p=0,019). La qualità di vita diventa sempre più importante nella gestione dei VS. In linea con questi risultati, noi sosteniamo la strategia non conservativa associata ad una riabilitazione vestibolare per quei pazienti con vertigini ed instabilità. La scala PANQOL, disponibile in lingua francese, si è rivelata specifica per i VS.

Clinically Definite Multiple Sclerosis

A secondary analysis was undertaken to compare patient-reported outcomes (PROs) of individuals who did and did not convert to clinically definite multiple sclerosis (CDMS) approximately 5 years after their first clinically isolated syndrome (CIS). Patients included in the analysis were participating in a long-term extension (called CHAMPIONS) of the Controlled High-Risk Avonex® Multiple Sclerosis Prevention Study (CHAMPS). The Multiple Sclerosis Quality of Life Inventory (MSQLI), a battery including the Short Form Health Status Survey (SF-36) and nine disease-specific scales, was administered to participants 5 years after their initial symptoms suggestive of MS (randomization into the CHAMPS study). Of 203 CHAMPIONS patients, 188 (93%) completed the MSQLI at enrollment into this extension study. Of these, 79 (42%) converted to CDMS. Statistically significant differences (P &lt; .001) between those who did and did not convert to CDMS were found for 4 of the 11 MSQLI scales: the SF-36 Physical Component Summary, the Modified Fatigue Impact Scale, the Pain Effects Scale, and the Bladder Control Scale. Trends not meeting our criteria for statistical significance (P &gt; .001 but &lt; .01) were observed for the SF-36 Mental Component Summary, the Perceived Deficits Questionnaire, and the Mental Health Inventory. SF-36 scores for patients not converting to CDMS over 5 years were similar to those reported for age-matched normal controls. No other demographic or disease-related factors were associated with these PROs. When stratified by Expanded Disability Status Scale score, patients who converted to CDMS demonstrated statistically significant differences on the same four scales defined above that differentiated those who did and did not convert to CDMS. These data show that individuals who have CDMS but limited disability demonstrate clear evidence of diminished health-related quality of life.

Background: Multiple sclerosis (MS) can have psychological and socioeconomic consequences that affect patients’ health-related quality of life (HRQoL) as much as physical disability. Objective: To determine the clinical and sociodemographic factors affecting HRQoL in a large international study using the MS International QoL (MusiQoL) questionnaire. Methods: Patients aged >18 years with a diagnosis of MS for >6 months or clinically isolated syndrome (CIS) were enrolled. Sociodemographic and clinical data were recorded, and patients completed the MusiQoL and 36-item short form (SF-36) health survey questionnaires. Results: In total, 1992 patients from 15 countries were enrolled (mean [standard deviation] age: 42.3 [12.5] years; 70.5% women; 70.4% with relapsing–remitting MS). Multivariate multiple regression analyses identified lower educational level, higher Expanded Disability Status Scale (EDSS) score, cognitive impairment, being single and shorter time since last relapse as significant predictors of lower MusiQoL global index scores ( p < 0.05). Older age, female sex, higher EDSS score, shorter time since last relapse and receiving current MS treatment were significant predictors of lower SF-36 physical component summary scores ( p < 0.05). The SF-36 mental component summary score was linked to occupational status, inpatient/outpatient status, time since last relapse, and whether the patient was receiving MS treatment ( p < 0.05). Conclusion: Sociodemographic and clinical factors are linked to HRQoL in patients with MS. Interventions that affect these factors might be expected to influence HRQoL.

BackgroundQuality of life is the subject of growing interest and investigation.AimsTo develop and validate a short, self-report quality of life questionnaire (the Schizophrenia Quality of Life Scale, SQLS).MethodPeople with schizophrenia in Liverpool were recruited via the NHS. Items, generated from in-depth interviews, were developed into an 80-item self-report questionnaire. Data were factor analysed, and a shorter form measure was tested for reliability and validity. This measure was administered together with other self-report measures – SF–36, GHQ–12 and HADS – to assess validity.ResultsData were analysed to produce a final 30-item questionnaire, comprising three scales (‘psychosocial’, ‘motivation and energy’, and ‘symptoms and side-effects’) addressing different SQLS dimensions. Internal consistency reliability of the scale was found to be satisfactory. There was a high level of association with relevant SF–36, GHQ–12 and HADS scores.ConclusionsThe SQLS was completed within 5–10 minutes. It possesses internal reliability and construct validity, and promises to be a useful tool for the evaluation of new treatment regimes for people with schizophrenia.

Purpose Exemestane, a steroidal aromatase inhibitor, reduced invasive breast cancer incidence by 65% among 4,560 postmenopausal women randomly assigned to exemestane (25 mg per day) compared with placebo in the National Cancer Institute of Canada (NCIC) Clinical Trials Group MAP.3 (Mammary Prevention 3) trial, but effects on quality of life (QOL) were not fully described. Patients and Methods Menopause-specific and health-related QOL were assessed by using the four Menopause-Specific Quality of Life Questionnaire (MENQOL) domains and the eight Medical Outcomes Study Short Form Health Survey (SF-36) scales at baseline, 6 months, and yearly thereafter. MENQOL questionnaire completion was high (88% to 98%) in both groups at each follow-up visit. Change scores for each MENQOL and SF-36 scale, calculated at each assessment time relative to baseline, were compared by using the Wilcoxon rank-sum test. Clinically important worsened QOL was defined as a MENQOL change score increase of more than 0.5 (of 8) points and an SF-36 change score decrease of more than 5 (of 100) points from baseline. Results Exemestane had small negative effects on women's self-reported vasomotor symptoms, sexual symptoms, and pain, which occurred mainly in the first 6 months to 2 years after random assignment. However, these changes represented only a small excess number of women being given exemestane with clinically important worsening of QOL at one time or another; specifically, 8% more in the vasomotor domain and 4% more each in the sexual domain and for pain. No other between-group differences were observed. Overall, slightly more women in the exemestane arm (32%) than in the placebo arm (28%) discontinued assigned treatment. Conclusion Exemestane given for prevention has limited negative impact on menopause-specific and health-related QOL in healthy postmenopausal women at risk for breast cancer.

Quality of life (HRQoL) is a measure of a person's health in physical, spiritual, and emotional, and role functions in the society. Measurement of quality of life (HRQoL) is an important thing to understand and evaluate. Measurements are carried out not only on patients but also on the general population with the use of specific or generic instruments. The instrument used requires a psychometric properties test to ensure its validity and reliability. This article aims to conduct a systematic review of the psychometric properties of quality of life (HRQoL) instruments in the general population. Articles were collected in December 1st to 5th, 2018, from Pubmed and Google Scholar. The assessment was carried out using the checklist properties according to the cohen criteria and included the content validity, construct validity, internal consistency reliability, test-retest, ceiling effect and the level of credibility of the instruments. Among 80 articles obtained there were 24 articles that fulfilled the inclusion criteria. Short Form-36 (SF-36) instrument is the most widely used instrument in measuring the quality of life in the general population (26.6%). Some instruments have not been tested according to the criteria, while almost all instruments show a good level of validation of construct validity using convergent and discriminat validity with cronbach alpha values > 0.7. Test-retest reliability provides a good correlation. Some instruments show a ceiling effect. According to the assessment, the SF-36, SF-6D, EQ-5D, SF-12 and PedsQoL instruments are considered as established instruments. Further validation testing is needed to provide and support the measurement of subsequent quality of life (HRQoL) instruments.
