Abstract
OBJECTIVE To establish the reliability and validity of the Korean version of LupusPRO version 1.7 (v1.7) for systemic lupus erythematosus (SLE) patients. METHODS LupusPRO v1.7 was translated into Korean, followed by pretesting among five native Korean speakers. We administered the LupusPRO v1.7 survey to five SLE patients and made minor changes to clarify the language. Then, 133 SLE patients participated in the validation procedure. In each domain, the internal consistency reliability (ICR) and test-retest reliability (TRR) were assessed using Cronbach's alpha and the intra-class correlation coefficient (ICC), respectively. Criterion validity was evaluated using Spearman's correlation coefficient with the other measures such as SF-36, EQ-5D VAS, and SELENA-SLEDAI PGA. Construct validity was assessed by confirmatory factor analysis (CFA) using the unweighted least square estimation method. RESULTS The mean age of the 133 patients was 36.14 years, and 97% of them were women. Analysis of 130 returned questionnaires revealed that most ICRs of the Korean LupusPRO v1.7 domains were acceptable, with Cronbach's alphas in the range of 0.579-0.949, and most TRRs were good with ICCs from 0.582 to 0.851. Criterion validities presented significant correlations between the LupusPRO v1.7 and other measures validated. In the analysis of the CFA model, the goodness of fit indices demonstrated an acceptable fit. Factor loadings for most individual items were between 0.548 and 0.985. The average variance extracted (AVE) and composite reliability (CR) of most domains were greater than 0.5 and 0.7, respectively, demonstrating acceptable convergent and discriminant validities. CONCLUSIONS The Korean version of LupusPRO v.17 had acceptable reliability and validity.

Abstract
Patient-reported outcome (PRO) instruments are widely used to assess quality of life in Systemic Lupus Erythematosus (SLE) research, and there is growing evidence for their use in clinical care. In this review, we evaluate the current evidence for their use in assessing quality of life in SLE in both research and clinical settings and examine the different characteristics of the commonly used PRO tools. There are now several well-validated generic and SLE-specific tools that have demonstrated utility in clinical trials and several tools that complement activity and damage measures in the clinical setting. PRO tools may help overcome physician–patient discordance in SLE and are valuable in the assessment of fibromyalgia and type 2 symptoms such as widespread pain and fatigue. Future work will identify optimal PRO tools for different settings but, despite current limitations, they are ready to be incorporated into patient care.

Abstract
Patient-reported outcome (PRO) was identified as a core systemic lupus erythematosus (SLE) outcome in 1999. More than 20 years later, however, generic PRO measures evaluating impact in SLE are used mainly for research. Generic and disease-targeted PRO tools have unique advantages. Significant progress in identification of patient disease-relevant PRO concepts and development of new PRO tools for SLE has occurred over the past 20 years. Further research needs to focus on responsiveness and minimally important differences of existing, promising PRO tools to facilitate their use in SLE patient care and research.

Abstract
OBJECTIVES Systemic lupus erythematosus (SLE) is a common systemic autoimmune disease that may lead to considerable physical, psychological, and socioeconomical burden. In previous studies, inconsistent results were reported for the association of disease activity and organ damage with health-related quality of life (HRQoL). This paper aimed to explore the relationship between disease activity, organ damage, and HRQoL measured by SF-36, EQ-5D, LupusQoL, and LupusPRO and investigate whether the correlation is region-specific. METHODS We systematically searched for studies reporting the association between SLE disease activity, organ damage, and HRQoL in MEDLINE, EMBASE, PsycINFO, World of Science, the Cochrane Library, and CINAHL from inception to December 2019. A meta-analysis and region subgroup analysis were performed with a random-effects model to estimate pooled correlation coefficients and heterogeneity. RESULTS Forty articles were included representing of 6079 adult SLE patients. The meta-analysis of SF-36 and LupusPRO studies revealed mild to moderate negative correlations between disease activity and domains of these HRQoL measurements (correlation coefficient r ranging from -0.27 to -0.07). Likewise, negative correlations were found between organ damage and domains of SF-36 and LupusPRO (r ranging from -0.25 to -0.08). The pooled correlation coefficient is relatively higher in physical functioning related domains than mental health. In the region subgroup analysis, disease activity had strong negative correlations with SF-36 domains in African and European SLE patients, while organ damage had the strongest negative correlation with SF-36 domains in Asian SLE patients (p < 0.010). CONCLUSION This study provides the first comprehensive assessment of the relationship between disease activity, organ damage, and four popular HRQoL instruments, which provides useful insight into the target therapy in SLE management.

Abstract
OBJECTIVE To translate and cross-culturally adapt the Arabic version of LupusPRO v.1.8 and to test its reliability and validity. METHODS LupusPRO was translated into the Arabic language following a standard procedure with forward-backward translation and was tested in patients with systemic lupus erythematosus (SLE) before use. The Arabic version was administered to 107 Egyptian SLE patients, along with a validated Arabic version of RAND 36-Item Health Survey 1.0 (SF-36). The internal consistency and test-retest reliability were determined. Validity was assessed by correlating LupusPRO scores with SF-36, Safety of Estrogens in Lupus Erythematosus National Assessment-Systemic Lupus Erythematosus Disease Activity Index (SELENA-SLEDAI) and Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI). The conceptual framework of the Arabic LupusPRO was evaluated using confirmatory factor analysis (CFA). RESULTS Among the 107 SLE patients, 95% were women with a median (range) age of 32 (18-55) years, median (range) SELENA-SLEDAI of 6 (0-23) and median (range) SDI of 0 (0-6). The Cronbach's alpha for the Arabic LupusPRO ranged from 0.71 to 0.98, except for the social support domain (0.65). Test-retest reliability ranged from 0.95 to 0.99. Convergent validity with corresponding domains of SF 36 was satisfactory. For criterion validity, there was a weak but significant correlation between several LupusPRO domains with SELENA-SLEDAI. CFA showed a good model fit. CONCLUSION The Arabic version of LupusPRO v1.8 is a reliable and valid tool for measuring quality of life among Arabic speaking SLE patients.

Abstract
Background LupusPRO is a SLE specific patient reported outcomes measure developed and validated in the USA. This study aimed to validate the Hindi version of LupusPRO in systemic lupus erythematosus (SLE) patients in India. Methods Disease activity and damage were assessed using SELENA–SLEDAI and SLICC/ACR damage Index respectively. Demographic and clinical features were recorded. The Hindi Version of LupusPRO and 36-Item Short Form Health Survey (SF-36) were administered for assessment of quality of life. Depression, anxiety and fatigue were assessed using Patient Health Questionnaire 9 (PHQ9), Generalized Anxiety Disorder 7 (GAD7) and Fatigue Severity Scale (FSS) respectively. Internal consistency reliability, test-retest reliability, convergent and discriminant validity (against corresponding domains of the SF-36, fatigue, depression and anxiety), criterion validity (against disease activity and damage) and known group validity were tested. Results A total of 144 (140 females) patients with SLE with a mean age of 32.48 ± 7.26 years participated in the study. The median (interquartile range) SELENA SLEDAI was 2 (5.5). The internal consistency reliability of the LupusPRO domains was >0.7 for most domains (except for lupus symptoms, lupus medication, procreation and social support).We noted good convergent validity of LupusPRO domains with corresponding domains of SF-36, pain vitality with fatigue (FSS) and emotional health domain with depression (PHQ9) and anxiety (GAD7). Criterion validity of lupus symptoms with disease activity was observed. Known group validity of the LupusPRO domains with patient reported health status was observed. Confirmatory factor analysis showed a good fit. Conclusion The Hindi LupusPRO has fair psychometric properties among Indian patients with SLE.

Abstract
OBJECTIVE Systemic lupus erythematosus (SLE) predominantly affects women. Clinical phenotype and outcomes in SLE may vary by sex and are further complicated by unique concerns that are dependent upon sex-defined roles. We aimed to describe sex differences in disease-specific quality of life (QoL) assessment scores using the Lupus Patient-Reported Outcome (LupusPRO) tool in a large international study. METHODS Cross-sectional data from 1,803 patients with SLE on demographics, self-identified sex status, LupusPRO, and disease activity were analyzed. The LupusPRO tool has 2 constructs: health-related QoL (HRQoL) and non-HRQoL. Disease activity and damage were evaluated using the Safety of Estrogens in Lupus Erythematosus National Assessment version of the Systemic Lupus Erythematosus Disease Activity Index and the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index, respectively. Nonparametric tests were used to compare QoL and disease activity by sex. RESULTS A total of 122 men and 1,681 women with SLE participated. The mean age was similar by sex, but the damage scores were greater among men. Men fared worse on the non-HRQoL social support domain than women (P = 0.02). When comparing disease and QoL among men and women ages ≤45 years, men were found to have greater damage and worse social support than women. However, women fared significantly worse on lupus symptoms, cognition, and procreation domains with trends for worse functioning on physical health and pain-vitality domains. CONCLUSION In the largest study of a diverse group of SLE patients, utilizing a disease-specific QoL tool, sex differences in QoL were observed on both HRQoL and non-HRQoL constructs. Although men performed worse in the social support domain, women (especially those in the reproductive age group) fared worse in other domains. These observations may assist physicians in appropriately addressing QoL issues in a sex-focused manner.

Abstract
OBJECTIVE The soluble triggering receptor expressed on myeloid cells (TREM-1)-like transcript 1 (sTLT-1) has a modulatory effect on the activation of TREM-1. We compared plasma sTLT-1 levels between patients with systemic lupus erythematosus (SLE) and healthy individuals and determined the association between sTLT-1 levels and clinical features and patient-reported outcomes (PROs) among patients with lupus. METHODS An unmatched case-control study was conducted in 46 patients with SLE and 28 healthy subjects. sTLT-1 plasma levels were determined using enzyme-linked immunosorbent assay. Demographic factors, SLE manifestations, comorbidities, pharmacologic profile, disease activity (per SLAM-R), damage accrual, and PROs (as per Lupus Patient-Reported Outcome [LupusPRO]) were studied. RESULTS Patients with SLE were found to have lower sTLT-1 levels compared with healthy individuals (9.0±7.2 vs. 18.6±22.3 pg/mL, p=0.008). Among patients with SLE, higher sTLT-1 levels were found in those taking corticosteroids (11.1±8.8 vs. 6.9±4.6 pg/mL, p=0.014). Significant correlations were found for the cognition (r=-0.442, p=0.027) and desires/goals (r=0.435, p=0.030) domains of LupusPRO. A tendency was observed between sTLT-1 levels and the SLAM-R (r=-0.278, p=0.064) and the lupus symptoms (r=-0.388, p=0.055) and physical health (r=-0.382, p=0.060) domains of LupusPRO. CONCLUSION Compared with healthy individuals, sTLT-1 levels were significantly lower in patients with SLE. Among patients with SLE, correlations were observed for some domains of LupusPRO. Given that sTLT-1 has anti-inflammatory properties, the deficiency of this protein could play an important role in the pathogenesis of SLE.

Abstract
Inclusion of patient-reported outcomes is important in SLE clinical trials as they allow capture of the benefits of a proposed intervention in areas deemed pertinent by patients. We aimed to compare the measurement properties of health-related quality of life (HRQoL) measures used in adults with SLE and to evaluate their responsiveness to interventions in randomised controlled trials (RCTs). A systematic review was undertaken using full original papers in English identified from three databases: MEDLINE, EMBASE and PubMed. Studies describing the validation of HRQoL measures in English-speaking adult patients with SLE and SLE drug RCTs that used an HRQoL measure were retrieved. Twenty-five validation papers and 26 RCTs were included in the indepth review evaluating the measurement properties of 4 generic (Medical Outcomes Study Short-Form 36 (SF36), Patient Reported Outcomes Measurement Information System (PROMIS) item-bank, EuroQol-5D, and Functional Assessment of Chronic Illness Therapy-Fatigue) and 3 disease-specific (Lupus Quality of Life (LupusQoL), Lupus Patient Reported Outcomes, Lupus Impact Tracker (LIT)) instruments. All measures had good convergent and discriminant validity. PROMIS provided the strongest evidence for known-group validity and reliability among generic instruments; however, data on its responsiveness have not been published. Across measures, standardised response means were generally indicative of poor-moderate sensitivity to longitudinal change. In RCTs, clinically important improvements were reported in SF36 scores from baseline; however, between-arm differences were frequently non-significant and non-important. SF36, PROMIS, LupusQoL and LIT had the strongest evidence for acceptable measurement properties, but few measures aside from the SF36 have been incorporated into clinical trials. This review highlights the importance of incorporating a broader range of SLE-specific HRQoL measures in RCTs and warrants further research that focuses on longitudinal responsiveness of newer instruments.

Abstract
Objectives LupusPRO has shown good measurement properties as a disease-specific patient-reported outcome tool in systemic lupus erythematosus (SLE). For the purpose of clinical trials, the version 1.7 (v1.7) domain of Pain-Vitality was separated into distinct Pain, Vitality and Sleep domains in v1.8, and the psychometric properties examined. Methods A total of 131 consecutive SLE patients were self-administered surveys assessing fatigue (FACIT, SF-36), pain (Pain Inventory, SF-36), insomnia (Insomnia Severity Index), emotional health (PHQ-9, SF-36) and quality of life (SF-36, LupusPRO) at routine care visits. Internal consistency reliability (ICR) for each domain was obtained using Cronbach's alpha. The convergent construct validity of LupusPRO domains with corresponding SF-36 domains or tools were tested using Spearman correlation. Varimax rotations were conducted to assess factor structures of the LupusPRO v1.8. Results Mean (SD) age was 40.04 (14.10) years. Scores from the LupusPRO-Sleep domain strongly correlated with insomnia scores, while LupusPRO-Vitality correlated strongly with fatigue (FACIT) and SF-36 vitality. The LupusPRO-Pain domain correlated strongly with pain (SF36 Bodily-Pain, Pain Inventory) scores. Similarly, the LupusPRO domains of Physical and Emotional Health had significant correlations with corresponding SF-36 domains. The ICR for HRQoL and non-HRQoL were 0.96 and 0.81. LupusPRO (domains HRQoL and QoL) scores correlated with disease activity. Principal component analysis included seven factor loadings presenting for the HRQOL subscales (combined Sleep, Vitality, and Pain), and three factors for the NHRQoL (Combined Coping and Social Support). Conclusions LupusPRO v1.8 (including its Sleep, Vitality, and Pain domains) has acceptable reliability and validity. Use of LupusPRO as an outcome measure in clinical trials would facilitate responsiveness assessment.

Abstract
Introduction Systemic lupus erythematosus (SLE) leads to a range of biopsychosocial health outcomes through an unpredictable and complex disease path. The LupusPRO is a comprehensive, self-report measure developed specifically for populations with SLE, which assesses both health-related quality of life and non-health related quality of life. Given its increasingly widespread use, additional research is needed to evaluate the psychometric integrity of the LupusPRO across diverse populations. The objectives of this study were to evaluate the performance of the LupusPRO in two divergent patient samples and the model fit between both samples. Methods Two diverse samples with SLE included 136 patients from an ethnically-diverse, urban region in southern California and 100 from an ethnically-homogenous, rural region in Manila, Philippines. All patients met the ACR classification criteria for SLE. Confirmatory factor analysis (CFAs) were conducted in each sample separately and combined to provide evidence of the factorial integrity of the 12 subscales in the LupusPRO. Results Demographic analyses indicated significant differences in age, disease activity and duration, education, income, insurance, and medication use between groups. Results of the separate CFAs indicated moderate fit to the data for the hypothesized 12-factor model for both the Manila and southern California groups, respectively [χ2 (794) = 1283.32, p < 0.001, Comparative Fit Index (CFI) = 0.793; χ2 (794) =1398.44, p < 0.001, CFI = 0.858]. When the factor structures of the LupusPRO in the southern California and Manila groups were constrained to be equal between the two groups, findings revealed that the factor structures of measured variables fit the two groups reasonably well [χ2 (1697) = 2950.413, df = 1697, p < 0.000; CFI = 0.811]. After removing seven constraints and eight correlations suggested by the Lagrange multiplier test, the model fit improved significantly [χ2 (15) = 147.165, p < 0.000]. Conclusions This research provides significant support for the subscale structure of the LupusPRO in two disparate cultural samples of SLE patients. Despite significant sociodemographic and clinical differences between the two samples, for the most part, the LupusPRO performed similarly in both samples.

Abstract
Objective This study aimed to validate the Japanese version of the LupusPRO questionnaire for use with systemic lupus erythematosus patients. Methods Participants were 205 lupus patients recruited from three rheumatology centers in Japan. Demographic data were collected and quality of life was assessed using the LupusPRO and the Short Form Health Survey-12. Disease activity was evaluated by physicians using the Systemic Lupus Erythematosus Activity Index. Some participants completed questionnaires 10-14 days after the first survey. Internal consistency reliability, test-retest reliability, content validity and convergent validity were examined, and confirmatory factor analysis was performed. Results Participants' mean age was 47.8 ± 13.6 years. Older participants scored lower on physical quality of life and higher on coping than younger participants. The LupusPRO showed satisfactory test-retest reliability ( n = 111). Test-retest reliability was lower for the mental and social aspects of quality of life, indicating fluctuations in quality of life during the two-week interval. Internal consistency reliability was good and convergent validity with the corresponding domains of the Short Form Health Survey-12 was satisfactory. Confirmatory factor analysis showed a good model fit. Conclusion The Japanese LupusPRO is a reliable and valid measure to evaluate treatment interventions for systemic lupus erythematosus.

Abstract
Objective: To determine patient-reported outcomes measures in indigent patients with systemic lupus erythematosus receiving their healthcare through the Puerto Rico government managed care system and compare these measures with non-indigent patients treated in a private fee-for-service setting. Methods: A cross-sectional study was conducted in a cohort of 98 Puerto Ricans with systemic lupus erythematosus. Patients from the public group (n = 40) were treated in a university-based specialized systemic lupus erythematosus clinic and the private group (n = 58) in a community-based rheumatology practice. Demographic and clinical features and patient-reported outcomes measures per LupusPRO instrument were determined. LupusPRO captures quality-of-life measures in 12 domains. Differences among study groups were examined using chi-square, Fisher’s exact, t-tests, and the Wilcoxon signed-rank test. Results: The mean (standard deviation) age of the study population was 44.9 (12.0) years; 94 (95.9%) were women. Patients in the public setting were younger and were more likely to have renal disease and elevated anti-double-stranded DNA antibodies, and being treated with azathioprine and cyclophosphamide. Patients from the public sector were more likely to have better quality-of-life measures in the LupusPRO domains of pain/vitality and coping. No significant differences were observed for the domains of lupus symptoms, physical health, emotional health, body image, cognition, procreation, lupus medications, desires/goals, social support, and satisfaction with medical care. Conclusion: Despite having a lower socioeconomic status and worse clinical status, systemic lupus erythematosus patients from the public sector had equal or better patient-reported outcomes measures than those treated in the private setting. This favorable outcome may be associated with the comprehensive healthcare received by these patients in a specialized lupus clinic.

Abstract
OBJECTIVES The objective of this article is to validate the Lupus Impact Tracker (LIT), a disease-specific patient-reported outcome (PRO) tool, in systemic lupus erythematosus (SLE) patients in a multi-ethnic Australian cohort. METHODS Patients attending the Monash Lupus Clinic were asked to complete the LIT, a 10-item PRO. Psychometric testing assessing criterion validity, construct validity, test-retest reliability (TRT) and internal consistency reliability (ICR) were performed. We compared the LIT scores across patient characteristics, and correlations between LIT scores and SLEDAI-2k, PGA, and SLICC-SDI were examined. RESULTS LIT data were obtained from 73 patients. Patients were 84% female with a median age of 41 years, and 34% were Asian. The cohort had mild-moderate disease activity with a median (IQR) Systemic Lupus Erythematosus Disease Activity Index-2000 (SLEDAI-2k) of 4 (IQR 2-6). The median LIT score was 32.5 (IQR 17.5-50). LIT demonstrated criterion validity against SLEDAI-2k and SDI. Construct validity assessed by confirmatory factor analysis demonstrated an excellent fit (Goodness of fit index 0.95, Comparative Fit Index 1, Root Mean Square Error of Approximation <0.0001). The LIT demonstrated TRT with an overall intraclass correlation coefficient of 0.986 (95% CI 0.968-0.995). ICR was demonstrated with a Cronbach's alpha of 0.838. Patients with disability, low socioeconomic status, or higher disease activity had significantly worse LIT scores. CONCLUSION The LIT demonstrated properties consistent with its being valid in this population. Lower socioeconomic status appears to have a significant impact on patient-reported health-related quality of life in SLE.

Abstract
Successful management of complex conditions such as systemic lupus erythematosus (SLE) and comorbid conditions benefit from patient-reported outcomes (PRO). Measuring health-related quality of life with PROs provides SLE patients with an opportunity to participate in their treatment and to facilitate better communication with the multidisciplinary team involved in their care. Health outcomes research has produced well-validated instruments that can be used across diseases; others have been specifically developed for SLE. The use of generic and SLE-specific PROs depends on needs, including population monitoring, treatment decision making, clinical trials research, and for evaluating and comparing the effect of therapies.

Abstract
OBJECTIVE To evaluate the responsiveness of Lupus Impact Tracker (LIT) to changes in physician and patient disease activity assessments over time. METHODS Available longitudinal data from routine patient care visits on LIT, physician assessed disease activity (physician global assessment (PGA), SELENA-SLEDAI score, SELENA Flare Index (SFI)), and patient-reported changes in systemic lupus erythematosus (SLE) health status were analyzed. Significant, clinically important change (worsening or improvement) in physician disease activity assessment or patient-reported SLE health status were judged using the following criteria: change of 0.3 on PGA, 4 on SELENA-SLEDAI, change in SFI status over time, and change of 2 in either direction in patient-reported SLE health status. Mixed model regression analysis was used to compare changes in LIT using the above criteria. RESULTS There were 1184 observations with significant changes in physician disease activity or patient-reported measure for 182 patients' data across 1364 visits. Patients' mean (SD) age and SELENA-SLEDAI were 43.5 (13.2) years and 6.4 (7.3) respectively. LIT mean scores decreased by more than 3 with improvement in PGA (standardized response mean -0.26, p < 0.05), while it increased by more than 5 with worsening in SELENA-SLEDAI (standardized response mean 0.42, p = 0.01). Mean change in LIT of greater than ±3 was noted with change in SFI status (p < 0.05). Mean LIT score decreased by greater than 4 and increased by greater than 2 with patient-reported improvement and worsening in SLE health status respectively (p < 0.05). CONCLUSIONS LIT is responsive to physician-assessed and patient-assessed changes in disease status. A mean LIT change of 2-4 may represent a significant clinical change in LIT. It is an effective tool that may be used by patients and physicians in tracking disease impact in SLE patients.

Abstract
OBJECTIVE LupusPRO is a disease-targeted, patient-reported outcome (PRO) measure that was developed and validated for assessment of quality of life in US patients with systemic lupus erythematosus (SLE). We present results of adapting the LupusPRO into Chinese and testing its psychometric properties in Chinese patients with SLE. METHODS LupusPRO was translated into "traditional" Chinese, followed by pretesting among native Cantonese Chinese speakers. The translation version was revised based on the feedback obtained. The Chinese language LupusPRO tool was administered along with a generic PRO tool (the Short Form 36 health survey [SF-36]) to ethnic Chinese SLE patients. At the same time, demographic information, clinical data, disease activity (Safety of Estrogens in Lupus Erythematosus National Assessment [SELENA] version of the Systemic Lupus Erythematosus Disease Activity Index [SLEDAI]), and damage (Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index [SDI]) were obtained. We performed confirmatory factor analysis of the Chinese LupusPRO and evaluated internal consistency reliability, as well as convergent and criterion validity. RESULTS Among the 463 SLE patients (95% women) with a mean ± SD age of 42.3 ± 13.5 years, the mean ± SD physician global assessment score was 0.48 ± 0.45, the mean ± SD SELENA-SLEDAI score was 2.9 ± 3.0, and the mean ± SD SDI score was 0.7 ± 1.2. Results of factor analysis conformed to the original LupusPRO model with only minor modifications. The reliability of the LupusPRO domains ranged from 0.60-0.94. LupusPRO domains had correlations as expected with the corresponding SF-36 domains. A significant but weak correlation with disease activity was noted for criterion validity as expected. CONCLUSION The Chinese language LupusPRO has fair psychometric properties and may be used in SLE clinical trials.

Abstract
OBJECTIVES The objective of this paper is to perform the cross-cultural validation of the French version of the LupusPRO, a disease-targeted patient-reported outcome measure, among systemic lupus erythematosus (SLE) patients in Canada. METHODS The French version of the LupusPRO and the MOS SF-36 were administered; demographic, clinical and serological characteristics were obtained. Disease activity (SELENA-SLEDAI and the Lupus Foundation of America definition of flare) and damage (SLICC/ACR SDI) were assessed. Physician disease activity and damage assessments were ascertained using visual analog scales. Internal consistency reliability (ICR), test-retest reliability (TRT), convergent and discriminant validity (against corresponding domains of the SF-36), criterion validity (against disease activity, damage or health status) and known group validity were tested. RESULTS A total of 99 French-Canadian SLE patients participated (97% women, mean (SD) age 45.2 (14.5) years). The median (IQR) SELENA-SLEDAI and SDI were 3.5 (6.0) and 1.0 (2.0), respectively. The ICR of the LupusPRO domains ranged from 0.81 to 0.93 (except for lupus symptoms, procreation and coping), while TRT ranged from 0.72 to 0.95. Convergent and discriminant validity, criterion validity and known group validity against disease activity, damage and health status measures were observed. Confirmatory factor analysis showed a good fit. CONCLUSION The LupusPRO has fair psychometric properties among French-Canadian patients with SLE.
