OBJECTIVE: To assess the psychometric properties, including responsiveness, of the World Health Organization Quality of Life instrument, short form (WHOQOL-BREF) in people with rheumatoid arthritis. METHODS: A sample of 142 persons with rheumatoid arthritis were randomly selected from a regional disease register and completed questionnaires by postal survey. An additional sample of 72 consecutive inpatients completed questionnaires a few days prior to admission, the day of admission, the day of discharge, and 2 weeks following discharge. RESULTS: Test-retest reliability was adequate (intraclass correlation coefficient 0.71-0.91). Internal consistency was adequate except for the social relationships domain (Cronbach's alpha 0.64-0.87). Factor structure was fairly similar to that previously reported. Correlation with other measures of quality of life was supportive of concurrent validity. Indices of responsiveness were satisfactory except for the social relationships and environment domains, although there was actually no statistical difference in the area under a receiver operating characteristic plot between the WHOQOL-BREF domains and the Health Assessment Questionnaire. CONCLUSION: The WHOQOL-BREF has adequate psychometric properties in people with rheumatoid arthritis and should be considered a valid outcome measure for interventions that aim to improve quality of life for people with this disease. 相似文献

OBJECTIVES: The aims of this study were to evaluate two condition-specific and two generic health status questionnaires for measuring health-related quality of life in patients with osteoarthritis (OA) of the knee, and to offer guidance to clinicians and researchers in choosing between them. METHODS: Patients were recruited from two settings: 118 from knee surgery waiting lists and 112 from rheumatology clinics. Four self-completion questionnaires [Western Ontario and McMaster University Osteoarthritis Index (WOMAC), Health Assessment Questionnaire (HAQ), Short Form-36 (SF-36) and Euroqol] were sent to subjects on two occasions 6 months apart. Construct validity, convergent validity, internal consistency and responsiveness were examined using primarily non-parametric methods. RESULTS: All instruments proved satisfactory in terms of ease of use, acceptability to patients, internal consistency and reliability. In the surgical group, the OA-specific WOMAC performed better than the HAQ and the generic measures in terms of validity and responsiveness to change, whereas in the rheumatology group the SF-36 was more responsive. CONCLUSION: WOMAC is the instrument of choice for evaluating the outcome of knee replacement surgery in OA. The SF-36 provides a more general insight into patients' health and may be more responsive to change than the WOMAC in a heterogeneous rheumatology clinic population. Researchers wishing to undertake an economic evaluation might consider the EQ-5D for a surgical, but not a rheumatology clinic group. 相似文献

Comparative responsiveness of measures of pain and function after total hip replacement. 总被引:3,自引:0,他引:3
A K Nilsdotter E M Roos J P Westerlund H P Roos L S Lohmander 《Arthritis and rheumatism》2001,45(3):258-262
OBJECTIVE: To compare the responsiveness of the Functional Assessment System (FAS), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and the Medical Outcomes Study 36-item Short Form (SF-36) in patients with osteoarthritis (OA) scheduled for total hip replacement. METHOD: Twenty patients with a mean age at surgery of 72.6 years, with primary OA of the hip, were investigated preoperatively and at 3, 6, and 12 months postoperatively with the FAS, WOMAC, and SF-36. The responsiveness was calculated as standardized response mean, effect size, and relative efficiency. RESULTS: The pain and function scores of WOMAC and SF-36 showed greater responsiveness than FAS at 3 months. These differences remained at 6 and 12 months postoperatively. The differences between these 3 outcome measures were found to be similar using several methods for calculating responsiveness. CONCLUSION: Self-administered questionnaires like WOMAC and SF-36 are more responsive measures of pain and function than range of motion, performance tests, and observer-administered questions (FAS) following total hip replacement. 相似文献

OBJECTIVES: Physical disability in patients with rheumatoid arthritis (RA) is often assessed by questionnaires. We compared the Health Assessment Questionnaire (HAQ) with the modified HAQ (MHAQ) in a cohort of RA patients across various levels of disability, and examined correlations with other measures of physical function. METHODS: Patients with RA (n = 182) completed self-report questionnaires assessing functional capacity. Instruments included the MHAQ and HAQ completed separately, as well as SF-36 and the Arthritis Impact Measurement Scales (AIMS). Scores from unadjusted and adjusted HAQ were compared with MHAQ at various disability levels. RESULTS: A clear ceiling effect with aggregation of normal scores for physical function was observed for MHAQ (23%) and HAQ (12%), but not for SF-36 (4%) or AIMS (5%). The correlations between adjusted/unadjusted HAQ and MHAQ scores were 0.85/0.88. A discrepancy in HAQ and MHAQ scores was observed in patients with high levels of disability, especially when MHAQ was compared with the adjusted final HAQ score. Adjustment of HAQ by aids or help increased the final score by an average of 0.15, and both adjusted and unadjusted HAQ scores were numerically clearly higher (mean 0.45 and 0.30, respectively) than the MHAQ score. CONCLUSION: The present findings indicate that MHAQ and HAQ may be applicable as measures of physical capacity in RA patients, but clinicians and researchers should select the appropriate instrument for the setting, and be aware of differences in scores, especially at different disability levels. 相似文献

Quality of life (QOL) of patients affected by various diseases is now recognized as an important outcome variable. Consenting
patients with rheumatoid arthritis (American College of Rheumatology criteria) were included in the study. Quality of life
was assessed using the World Health Organization Quality of Life assessment, short form (WHOQOL-BREF). Disease activity was
assessed by the Disease Activity Score (DAS28) for 3 variables and functional disability by the Health Assessment Questionnaire
(HAQ). Extra-articular manifestations (ExRA) were diagnosed clinically. Seventy-five age-matched normal controls and 136 patients
(19 males) were included. The mean duration of rheumatoid arthritis (RA) was 9 ± 5.8 years. The mean DAS28 and HAQ were 4.43
± 1.4 and 0.97 ± 1.6, respectively. At least one ExRA was present in 30 (22.1%) patients. The WHOQOL scores were significantly
lower in patients with RA compared to normal controls. Patients and normal controls scored highest in the social relationship
domain. There was significant inverse correlation of HAQ with all four domains of WHOQOL. There was significant inverse correlation
of DAS28 with the physical health and psychological domains. Patients with ExRA scored significantly lower in the physical
health domain of WHOQOL. Multiple regression analysis showed only HAQ to independently affect QOL. Quality of life is compromised
in patients with RA. Patients and normal controls scored higher in the social relationship domain. Functional disability is
the most important factor affecting QOL in RA. 相似文献

BACKGROUND: while life expectancy among older people has been lengthened due to improved public health and medical interventions, the importance of health-related quality of life in later life has also increased. However, the application of a generic health-related quality of life measure for older people needs to be carefully validated. OBJECTIVE: to evaluate the practicality, reliability, validity, and responsiveness of the use of the brief version of the World Health Organization Quality of Life for people aged 65 years or older. DESIGN: a prospective study. METHODS: for a baseline assessment, 1200 community-dwelling older people living in Shin-Sher Township of Taichung County, Taiwan, completed the brief version of World Health Organization Quality of Life at their residences either by themselves or with the assistance of an interviewer. Furthermore, score changes in each health-related quality of life domain after a fall were followed up for assessing its responsiveness. RESULTS: the average length of time required to complete the questionnaire was short (10.6 minutes for self-administration and 15.3 minutes for personal interview), and the score distribution in each domain was symmetrical with no floor or ceiling effect. Furthermore, all domain scores indicated excellent discriminant validity, construct validity, and responsiveness as well as good internal consistency and intra- and inter-observer test-retest reliabilities. Nevertheless, two items related to work capacity and sexual activity had higher missing values (4.5% and 16.5%) and poor interobserver test-retest reliabilities (0.43 and 0.20). Suggested modifications to the two items for older people are discussed. CONCLUSION: with a few modifications, the brief World Health Organization Quality of Life is a suitable health-related quality of life instrument for older people. 相似文献

OBJECTIVES: To compare the effects of three fall-prevention programs (education (ED), home safety assessment and modification (HSAM), and exercise training (ET)) on quality of life (QOL), functional balance and gait, activities of daily living (ADLs), fear of falling, and depression in adults aged 65 and older. DESIGN: A 4-month randomized trial. SETTING: Randomized, controlled trial. PARTICIPANTS: One hundred fifty participants who had experienced a recent fall. MEASUREMENTS: QOL was assessed according to the brief version of the World Health Organization Quality of Life instrument (WHOQOL-BREF), functional balance and gait according to functional reach and Tinetti balance and gait, ADLs according to the Older Americans Resources and Services questionnaire, fear of falling according to a visual analog scale, and depression level according to the Geriatric Depression Scale. RESULTS: The score changes for the ET group were 2.1 points greater on the physical domain (95% confidence interval (CI)=-1.2-5.3), 3.8 points greater on the psychological domain (95% CI=0.7-7.0), and for the WHOQOL-BREF, 3.4 points greater on the social domain (95% CI=0.7-6.1) and 3.2 points greater on the environmental domain (95% CI=0.6-5.7) than for the ED group. The score change for each domain of the WHOQOL-BREF for the HSAM group was greater than that for the ED group, although these results were not statistically significant. The ET group also had greater improvements in functional reach, Tinetti balance and gait, and fear of falling than the ED group. CONCLUSION: The QOL outcome supports the superiority of ET over the other two interventions in older people who have recently fallen. This finding also parallels those gathered from the functional measures. 相似文献

OBJECTIVE: To assess the reliability, validity and sensitivity to change of a Chinese version of the 36-item Short-Form Health Survey (SF-36) in Chinese-speaking patients with rheumatoid arthritis (RA) in Singapore. METHODS: The psychometric properties of the Chinese Hong Kong standard version of the SF-36 were assessed in 401 RA patients. The construct validity of the Chinese SF-36 was assessed by comparison with the American College of Rheumatology (ACR) functional status, a validated Chinese Health Assessment Questionnaire (C-HAQ) and markers of RA activity and severity. RESULTS: The overall Cronbach's coefficient alpha was 0.921, reflecting excellent internal consistency. The instrument showed reasonable test-retest reliability except in the social functioning (SF) subscale. There was a significant ceiling effect in the role physical (RP), SF and role emotional (RE) subscales and a floor effect in the RP and RE subscales. Physical function (PF) and SF were strongly correlated with C-HAQ and patient's assessment of RA activity [Pearson's correlation coefficient (r) ranging from -0.41 to -0.53] and moderately correlated with ACR functional status (r = -0.35 and -0.3, respectively). Weak correlations were also found between the Chinese SF-36 and markers of RA activity, deformed joint count and radiographic damage. PF and SF were the subscales most responsive to change in quality of life (QOL). CONCLUSION: The Chinese SF-36 showed reasonable reliability, criterion validity and responsiveness with limitations in certain subscales. Overall, the physical domains and PF in particular may be the most ideal psychometric measures of QOL in RA. 相似文献

OBJECTIVE: To compare the responsiveness of the condition-specific Western Ontario and McMaster Universities osteoarthritis (OA) index (WOMAC) and the generic Short Form-36 (SF-36) in patients with OA of the legs undergoing a comprehensive inpatient rehabilitation intervention. METHODS: A prospective follow up study of consecutively referred inpatients of a rehabilitation clinic was made. The patients included fulfilled the American College of Rheumatology criteria for knee or hip OA and underwent both passive and, particularly, active physical therapy for three to four weeks. Responsiveness assessment was performed using the standardised response mean (SRM), effect size, and Guyatt's responsiveness statistic between admission and discharge (end of rehabilitation) and then again between admission and three months later. For pain and function the SRMs were stratified by sex and OA joint. Effects were tested by the t test and SRMs of different scales were compared by the jack knife test. RESULTS: At the three month follow up, complete data were obtained for 223 patients. In general, the three responsiveness statistics showed a similar order of responsiveness. For both instruments, the pain scales were more responsive than the function scales. The responsiveness of the pain scale of both instruments was comparable (SRM=0.723 for WOMAC and SRM=0.528 for SF-36 at the end of rehabilitation; SRM=0.377 for WOMAC and SRM=0.468 for SF-36 at the three month follow up). In the measurement of function, the WOMAC was significantly more responsive than the SF-36 (SRMs, end of rehabilitation: 0.628 v 0.249; three month follow up: 0.235 v -0.001). Responsiveness tended to be higher in women and in knee OA than in men and hip OA. CONCLUSIONS: Both instruments, the WOMAC and the SF-36, capture improvement in pain in patients undergoing comprehensive inpatient rehabilitation intervention. Functional improvement can be detected better by the WOMAC than by the SF-36. All the other scales of both instruments were more weakly responsive. 相似文献

Background: Quality of life (QoL) is an important clinical and research outcome within the drug and alcohol abuse context. The AlQoL 9 is a specific questionnaire designed to assess health- and non-health-related consequences of alcoholism. The English version of the AlQoL 9 has not been validated using a larger sample. Objectives: The aim of this study was to assess the psychometric properties of the English version of AlQoL 9 in a sample of treatment-seeking individuals in Australia. Methods: A sample of 138 participants from inpatient and outpatient treatments facilities completed the AlQoL 9 test and the World Health Organisation Quality of Life Assessment-BREF (WHOQOL-BREF). The study’s investigative parameters included the demographic characteristics of the sample, internal structure, and convergent validity. Furthermore, correlations between the AlQoL 9 scale scores and the scores obtained from the WHOQOL-BREF test were investigated using Pearson product-moment correlation analyses. Results: The English version of the AlQoL 9 attained a significant Cronbach’s alpha of 0.825. The mean score obtained in the test was 21.92 (SD?=?6.79). Using Varimax rotation, the AlQoL 9 yielded one principal factor that had accounted for 37.85% of variance. Convergent validity analysis demonstrated significant correlations (p?0.001) between the AlQoL 9 scores and the scores of all four dimensions of the WHOQOL-BREF questionnaire. Conclusion: The present study demonstrated that the English version of the AlQoL 9 constitutes a valid and reliable research instrument for evaluating quality of life among alcohol-dependent individuals. 相似文献

OBJECTIVE: To develop a reliable and valid instrument for measuring and monitoring joint-specific pain. METHODS: Developed using patient interviews, reviews of pain literature, and expert input from orthopedic surgeons, the final Joint-Specific Multidimensional Assessment of Pain (J-MAP) includes the 6-item Pain Sensory and the 4-item Pain Affect subscales. Scores on the J-MAP Pain Sensory and Affect subscales range from 0 to 100, with higher scores indicating more pain intensity and worse pain distastefulness, respectively. Following the assessment of the factor structure, patients' scores (n = 180) on the J-MAP subscales were converted to equal interval scores using Rasch analyses. A psychometric evaluation of the items and Rasch-calibrated scores was conducted and included an assessment of reliability, validity, and responsiveness for use with patients with radiographic knee osteoarthritis. RESULTS: Evidence from the factor analyses showed that the J-MAP Pain Sensory and Affect items made up 2 distinct factors. Internal consistency estimates for the J-MAP subscales exceeded 0.85. The J-MAP subscales showed evidence for validity and were shown to be internally and externally responsive, demonstrating greater responsiveness than the Arthritis Impact Measurement Scale or the Medical Outcome Study Short Form-36 pain subscales. Finally, evidence was found supporting the J-MAP subscales' ability to distinguish target joint pain from pain emanating from other musculoskeletal conditions. CONCLUSION: The J-MAP is a reliable, valid, and responsive measure for assessing joint-specific pain at a single time point, or changes over time for one or a group of patients with knee osteoarthritis. With this initial evidence of its psychometric rigor, further testing of the measurement properties of the J-MAP in other joints and in other populations should be undertaken. 相似文献

AbstractCOPD is a leading chronic disease, increasing globally. Given this condition's irreversible and progressive nature, health-related quality of life (HRQOL) is increasingly a primary end-point in COPD management. We evaluated several HRQOL tools with a primary goals of (1) investigating how the generic Assessment Quality of Life (AQOL) functions compared to the Medical Outcomes Study 36-item Short Form Health Survey (SF36) and the St. Georges Respiratory Questionnaire (SGRQ); and (2) considering the extent to which clinical disease severity, as measured by the BODE index, predicts variation in HRQOL reports. Methods: 134 consecutive patients entering a pulmonary rehabilitation program were recruited. Participants completed two generic measures of HRQOL (SF36 and AQOL) and one disease specific measure (SGRQ). The clinical severity of COPD was assessed using a composite global COPD severity score, BODE. Results: Significant associations were demonstrated between AQOL and both the SF36 (r = .68) and SGRQ (r = –.60). BODE significantly predicted AQOL scores (R = –.31); mMRC (R = –.36) and 6MWD (R = .39) were stronger contributors to these predictions than were FEV1 or BMI. Conclusions: This study establishes convergent validity between AQOL, and the SF36 and SGRQ in patients with COPD. For future studies wishing to examine HRQOL from a generic perspective, we have shown that during cross-sectional analyses AQOL performs similarly to the SF36. In addition we identified that the clinical severity of COPD, as assessed by BODE, significantly influences reports of quality of life made using AQOL. The components of BODE that most strongly contributed to predicting HRQOL were dsypnea and exercise tolerance. 相似文献

OBJECTIVES: To compare the relative responsiveness of condition specific measures with that of a generic health status instrument for outcome assessment of intra-articular corticosteroid (IAC) injection in patients with juvenile idiopathic arthritis (JIA). METHODS: We examined 44 consecutive patients with oligoarticular JIA before an IAC injection and after 6 months. Condition specific measures included physician's and parent's global assessments, the Childhood Health Assessment Questionnaire (CHAQ), the articular indices, and laboratory indicators of systemic inflammation. The generic health status instrument was the Child Health Questionnaire (CHQ), which was divided into two parts: the physical score (PhS) and the psychosocial score (PsS). Responsiveness statistics were the standardised response mean, the effect size, and Guyatt's method. The discriminative ability of the clinical measures in distinguishing improved from non-improved patients was evaluated with the correlation and the receiver operating characteristic methods, using the physician's and the parent's judgements of the treatment outcome as external criteria. RESULTS: All responsiveness statistics and discriminative ability assessments consistently ranked the physician's global assessment of the disease activity as the most responsive measure. The CHQ-PhS revealed superior ability in detecting baseline versus 6 month change compared with the CHAQ and the CHQ-PsS; both summary scales of the CHQ revealed better discriminative ability than the CHAQ. CONCLUSIONS: The physician's global assessment of the disease activity proved the most responsive outcome measure in our patients with JIA. The relative evaluative properties of the generic health status instrument and the CHAQ should be further investigated. 相似文献

OBJECTIVE: To assess the measurement properties of a simple index of symptom severity in osteoarthritis (OA) of the hips and knees. METHODS: Both the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the proposed new Comprehensive Osteoarthritis Test (COAT) instrument were completed weekly by 125 subjects in the context of a randomized, 12-week, 3 parallel-arm clinical trial. The reliabilities of the various scales were assessed on a weekly basis by use of Cronbach's alpha coefficients. The validity of the COAT total scale was assessed by correlation with the WOMAC total scale on a weekly basis with correlation coefficients, and in terms of the correlations between subject-level intercepts and slopes over time. The relative responsiveness of the WOMAC and COAT total scales was assessed using a multilevel (longitudinal) multivariate (WOMAC, COAT) linear model. RESULTS: The WOMAC and COAT total scales were highly reliable (mean over weeks: WOMAC alpha = 0.98; COAT alpha = 0.97). The correlations between the WOMAC and COAT scales were very high (mean over weeks = 0.92; subject-level intercepts = 0.91, slopes = 0.88). The COAT total scale was significantly more responsive than the WOMAC total scale in the active treatment (34.8% improvement vs 26.8%; p = 0.002). CONCLUSION: The COAT total scale is simple to administer, reliable, valid, and responsive to treatment effects. 相似文献

OBJECTIVE: To validate the WOMAC Osteoarthritis Index for use in Sweden. METHODS: Test-retest reliability, internal consistency, validity, and responsiveness was determined in 52 patients (mean age 48 (20-69)) with arthroscopically assessed cartilage damage of the tibio-femoral knee joint. RESULTS: All WOMAC scales were internally consistent with Cronbach's alpha coefficients of 0.83, 0.87, and 0.96 pre-operatively. Test-retest reliability was satisfactory with intraclass correlation coefficients of 0.74, 0.58, and 0.92. As hypothesized worse post-operative but not pre-operative outcomes were associated with radiographic OA. In comparison with the SF-36 the expected correlations were found when comparing items measuring similar and dissimilar constructs, supporting the concepts of convergent and divergent construct validity. Three months after arthroscopy significant mean improvement was seen in all WOMAC scales (p<0.0004). CONCLUSION: The Swedish version of WOMAC is a reliable, valid, and responsive instrument with metric properties in agreement with the original widely used version. 相似文献

Rheumatoid arthritis is a chronic inflammatory disease with a major impact on physical and psychological health. It can cause severe disability and reduce health-related quality of life, aspects that are important to patients. Thus, it is important to measure disability and health-related quality of life in clinical practice and in clinical trials. This article presents an overview of the most important measures of outcome concerning disability and health-related quality of life, including different forms of the Health Assessment Questionnaire (HAQ, MHAQ, MDHAQ, HAQ II), visual analogue scales for fatigue and function, SF-36, Arthritis Impact Measurement Scales (AIMS/AIMS2), the Rheumatoid Arthritis Quality of Life (RAQoL) questionnaire, Nottingham Health Profile, Sickness Impact Profile and the utility instruments 15D, EQ-5D, SF-6D and Health Utilities Index (HUI) 2 and 3. 相似文献

OBJECTIVE: To adapt the Rheumatoid Arthritis Quality of Life (RAQoL) questionnaire for Swedish patients and evaluate psychometric properties in a prospective study. METHODS: Reliability was assessed in 61 patients filling in RAQoL two times with one week's interval. 114 patients completed RAQoL and Nottingham Health Profile (NHP) on 2-3 occasions 6 months apart. Validity was evaluated comparing RAQoL-scores to disease-related variables and NHP subscales. Standardized response mean was applied to calculate responsiveness with the RA-related variables as external indicators of change. RESULTS: Test-retest reliability was high and internal consistency sufficient. RAQoL correlated as expected to NHP section scores. In a multivariate model the Stanford Health Assessment Questionnaire disability index (HAQ) and general health could explain 40% and disease activity measures 13% of the variance of RAQoL. Correlations between change scores of clinical variables and RAQoL and NHP were weak but positive. Standardized response means regarding change of disease activity, HAQ, and general health were small but in the same range for both RAQoL and NHP. CONCLUSION: The Swedish RAQoL had similar measurement properties as the original version. However, responsiveness regarding condition specific measures was not better than for the generic instrument NHP. 相似文献
