Comparing measurement properties of EQ-5D-Y-3L and EQ-5D-Y-5L in paediatric patients

Abstract Background The adult versions EQ-5D-3L and EQ-5D-5L have been extensive compared. This is not the case for the EQ-5D youth versions. The study aim was to compare the measurement properties and responsiveness of EQ-5D-Y-3L and EQ-5D-Y-5L in paediatric patients. Methods A sample of patients 8–16 years old with different diseases and a wide range of disease severity was asked to complete EQ-5D-Y-3L, EQ-5D-Y-5L, PedsQL Generic Core Scale, and selected, appropriate disease-specific instruments, three times. EQ-5D-Y-3L and EQ-5D-Y-5L were compared in terms of: feasibility, (re-)distribution properties, discriminatory power, convergent validity, test–retest reliability, and responsiveness. Results 286 participating patients suffered from one of the following diseases: major beta-thalassemia, haemophilia, acute lymphoblastic leukaemia, acute illness. Missing responses were comparable between versions of the EQ-5D-Y, suggesting comparable feasibility. The number of patients in the best health state (level profile 11111) was equal in both EQ-5D-Y versions. The projection of EQ-5D-Y-3L scores onto EQ-5D-Y-5L for all dimensions showed that the two additional levels in EQ-5D-Y-5L slightly improved the accuracy of patients in reporting their problems, especially if severe. Convergent validity with PedsQL and disease-specific measures showed that the two EQ-5D-Y versions performed about equally. Test–retest reliability (EQ-5D-Y-3L 0.78 vs EQ-5D-Y-5L 0.84), and sensitivity for detecting health changes, were both better in EQ-5D-Y-5L. Conclusions Extending the number of levels did not give clear superiority to EQ-5D-Y-5L over EQ-5D-Y-3L based on the criteria assessed in this study. However, increasing the number of levels benefitted EQ-5D-Y performance in the measurement of moderate to severe problems and especially in longitudinal study designs.

Background The Patient-Rated Tennis Elbow Evaluation (PRTEE) questionnaire is a tool designed for self-assessment of forearm pain and disability in patients with lateral elbow tendinopathy (LET). However, an Italian version of this questionnaire has not been available. Objective The aims of this study were: (1) to translate and cross-culturally adapt the PRTEE questionnaire into Italian and (2) to evaluate its measurement properties. Design This was a longitudinal, observational measurement study. Methods The PRTEE questionnaire was cross-culturally adapted to Italian according to established guidelines. Ninety-five individuals (41 women, 54 men) with unilateral, imaging-confirmed, chronic LET were selected consecutively to assess the measurement properties of the PRTEE questionnaire. Internal consistency, test-retest reliability, construct validity, and responsiveness were estimated. Results The Italian version of the PRTEE displayed a high degree of internal consistency, with a Cronbach alpha of .95. The test-retest reliability was high for both short-term and medium-term, with intraclass correlation coefficients (2,1) of .95 and .93, respectively. The PRTEE exhibited a strong correlation (r=.77–.91, P<.0001) with the Disabilities of the Arm, Shoulder and Hand (DASH) at the baseline and a moderate correlation (r=.58–.74, P<.0001) at discharge. The responsiveness was higher for the PRTEE than for the DASH. Limitations A methodological limitation of the study is that due to the small sample size, a factor analysis was not performed to assess convergent validity. Conclusions The Italian version of the PRTEE questionnaire is internally consistent, demonstrates expected correlations with other measures, and is more responsive than the DASH in Italian patients with chronic LET.

Abstract Purpose Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease that affects up to 1% of the population in Europe. The EQ-5D is the most commonly used generic instrument for measuring health-related quality of life among HS patients. This study aims to compare the measurement properties of the two adult versions of EQ-5D (EQ-5D-3L and EQ-5D-5L) in patients with HS. Methods We recruited 200 consecutive patients with HS (mean age 37 years, 38% severe or very severe HS) to participate in a multicentre cross-sectional survey. Patients completed the EQ-5D-3L, EQ-5D-5L, Dermatology Life Quality Index (DLQI) and Skindex-16 questionnaires. Results More than twice as many different health state profiles occurred in the EQ-5D-5L compared to the EQ-5D-3L (101 vs. 43). A significant reduction in ceiling effect was found for the mobility, self-care and usual activities dimensions. A good agreement was established between the EQ-5D-3L and EQ-5D-5L with an intraclass correlation coefficient of 0.872 (95% CI 0.830–0.903; p < 0.001) that was confirmed by a Bland-Altman plot. EQ-5D-5L improved both the absolute and relative informativity in all dimensions except for anxiety/depression. EQ-5D-3L and EQ-5D-5L demonstrated similar convergent validity with DLQI and Skindex-16. EQ-5D-5L was able to better discriminate between known groups of patients based on the number of comorbidities and disease severity (HS-Physician's Global Assessment). Conclusion In patients with HS, the EQ-5D-5L outperformed the EQ-5D-3L in feasibility, ceiling effects, informativity and known-groups validity for many important clinical characteristics. We recommend using the EQ-5D-5L in HS patients across various settings, including clinical care, research and economic evaluations.

Abstract Background To evaluate the psychometric and measurement properties of two patient-reported outcome instruments, the menstrual pictogram superabsorbent polymer-containing version 3 (MP SAP-c v3) and Uterine Fibroid Daily Bleeding Diary (UF-DBD). Test-retest reliability, criterion, construct validity, responsiveness, missingness and comparability of the MP SAP-c v3 and UF-DBD versus the alkaline hematin (AH) method and a patient global impression of severity (PGI-S) were analyzed in post hoc trial analyses. Results Analyses were based on data from up to 756 patients. The full range of MP SAP-c v3 and UF-DBD response options were used, with score distributions reflecting the cyclic character of the disease. Test-retest reliability of MP SAP-c v3 and UF-DBD scores was supported by acceptable intraclass correlation coefficients when stability was defined by the AH method and Patient Global Impression of Severity (PGI-S) scores (0.80–0.96 and 0.42–0.94, respectively). MP SAP-c v3 and UF-DBD scores demonstrated strong and moderate-to-strong correlations with menstrual blood loss assessed by the AH method. Scores increased in monotonic fashion, with greater disease severities, defined by the AH method and PGI-S scores; differences between groups were mostly statistically significant (P < 0.05). MP SAP-c v3 and UF-DBD were sensitive to changes in disease severity, defined by the AH method and PGI-S. MP SAP-c v3 and UF-DBD showed a lower frequency of missing patient data versus the AH method, and good agreement with the AH method. Conclusions This evidence supports the use of the MP SAP-c v3 and UF-DBD to assess clinical efficacy endpoints in UF phase III studies replacing the AH method.

Abstract Background Fluid intelligence deficits affect executive functioning and social behaviors in patients with schizophrenia. To help clinicians manage fluid intelligence deficits, a psychometrically sound measure is needed. The purposes of this study were to examine the test–retest reliability and convergent validity of the Test of Nonverbal Intelligence-Fourth Edition (TONI-4) assessing fluid intelligence in patients with schizophrenia. Methods A total of 103 patients with stable condition were assessed with the TONI-4 twice with a 4-week interval to examine the test–retest reliability. We further used the Montreal Cognitive Assessment (MoCA) and the Tablet-Based Symbol Digit Modalities Test (T-SDMT) to examine the convergent validity of the TONI-4. Results The intra-class correlation coefficient was 0.73 for the TONI-4. The percentages of standard error of measurement and minimal detectable change for the TONI-4 were 5.1 and 14.2%, respectively. The practice effect of the TONI-4 was small (Cohen’s d = − 0.03). Convergent validity showed small to moderate significant correlations between the TONI-4 and the MoCA as well as the T-SDMT (r = 0.35, p = .011 with the T-SDMT and r = 0.61, p < .001 with the MoCA). The results demonstrated that the TONI-4 had good test–retest reliability, limited random measurement error, and a trivial practice effect. The convergent validity of the TONI-4 was good. Conclusions These findings indicate that the TONI-4 has potential to be a reliable and valid assessment of fluid intelligence in patients with schizophrenia.

Abstract Objectives To examine the validity and reliability of the Mandarin version of the Treatment Burden Questionnaire (TBQ) among stroke patients. Background Stroke patients need long-term management of symptoms and life situation, and treatment burden has recently emerged as a new concept that can influence the health outcomes during the rehabilitation process. Methods The convenience sampling method was used to recruit 187 cases of stroke patients in a tertiary grade hospital in Tianjin for a formal investigation. Item analysis, reliability and validity tests were carried out. The reliability test included internal consistency and test–retest reliability. And as well as content, structure and convergent validity were performed for the validity test. Results Of the 187 completed questionnaires, only 180 (96.3%) were suitable for analysis. According to the experts’ evaluation, the I-CVI of each item was from 0.833 to 1.000, and the S-CVI was 0.967. The exploratory factor analysis yielded three-factor components with a cumulative variation of 53.054%. Convergent validity was demonstrated using measures of Morisky’s Medication Adherence Scale 8 (r = –0.450, P < 0.01). All correlations between items and global scores ranged from 0.403 to 0.638. Internal consistency reliability and test–retest reliability were found to be acceptable, as indicated by a Cronbach’s α of 0.824 and an intraclass correlation coefficient of 0.846, respectively. Conclusions The Mandarin TBQ had acceptable validity and reliability. The use of TBQ in the assessment of treatment burden of stroke survivor may benefit health resources allocation and provide tailor therapeutic interventions to construct minimally disruptive care.

The North American Research Committee on Multiple Sclerosis (NARCOMS) Registry is a multiple sclerosis (MS) self-report registry with more than 24 000 participants. Participants report disability status upon enrolment, and semi-annually using Performance Scales (PS), Patient Determined Disease Steps (PDDS) and a pain question. In November 2000 and 2001, we also collected the Pain Effects Scale (PES). Our aim was to validate the NARCOMS pain question using the PES as our criterion measure. We measured correlations between the pain question and age, disease duration, various PS subscales and PDDS to assess construct validity. We correlated pain question responses in participants who reported no change in PDSS or the PS subscales between questionnaires to determine test—retest reliability. We measured responsiveness in participants who reported a substantial change in the sensory, spasticity PS subscales. The correlation between the pain question and PES was r=0.61 in November 2000, and r=0.64 in November 2001 (both P<0.0001). Correlations between the pain question and age, and disease duration were low, indicating divergent validity. Correlations between the pain question and spasticity, sensory PS subscales and PDSS were moderate, indicating convergent validity. Test—retest reliability was r=0.84 (P<0.0001). Responsiveness was 70.7%. The pain question is a valid self-report measure of pain in MS.

Objectives: This study conducted a linguistic and psychometric evaluation of the Chinese Counseling Competencies Scale-Revised (CCS-R).Methods: The Chinese CCS-R was created from the original English version using a standard forward-backward translation process. The psychometric properties of the Chinese CCS-R were examined in a cohort of 208 counselors-in-training by two independent raters. Fifty-three counselors-in-training were asked to undergo another counseling performance evaluation for the test-retest. The confirmatory factor analysis (CFA) was conducted for the Chinese CCS-R, followed by internal consistency, test-retest reliability, inter-rater reliability, convergent validity, and concurrent validity.Results: The results of the CFA supported the factorial validity of the Chinese CCS-R, with adequate construct replicability. The scale had a McDonald's omega of 0.876, and intraclass correlation coefficients of 0.63 and 0.90 for test-retest reliability and inter-rater reliability, respectively. Significantly positive correlations were observed between the Chinese CCS-R score and scores of performance checklist (Pearson's γ = 0.781), indicating a large convergent validity, and knowledge on drug abuse (Pearson's γ = 0.833), indicating a moderate concurrent validity.Conclusion: The results support that the Chinese CCS-R is a valid and reliable measure of the counseling competencies.Practice implication: The CCS-R provides trainers with a reliable tool to evaluate counseling students' competencies and to facilitate discussions with trainees about their areas for growth.

Background. Sleep disorders are common in perinatal women and may underlie or trigger anxiety and depression. We aimed to translate and validate and evaluate the psychometric properties of the Italian version of the Insomnia Symptom Questionnaire (ISQ), in a sample of women during late pregnancy and 6-months postpartum according to the DSM-5 criteria. Methods. The ISQ was administered to 292 women prenatally along with other measures of sleep quality, depression, and anxiety, to examine its construct and convergent validity. Women were readministered the ISQ six months postdelivery to assess test–retest reliability. Women were divided into DSM-5 No-Insomnia (N = 253) and Insomnia (N = 39) groups. Results. The insomnia group had received more psychopharmacotherapy, had more psychiatric family history, increased rates of medically assisted reproduction, of past perinatal psychiatric disorders, and scored higher on almost all TEMPS-A dimensions, on the EPDS, HCL-32, PSQI, and on ISQ prenatally and postnatally. ISQ scores correlated with all scales, indicating adequate convergent and discriminant validity; furthermore, it showed antenatal–postnatal test–retest reliability, 97.5% diagnostic accuracy, 79.5% sensitivity, 94.9% specificity, 70.5% positive predictive power, and 92.8% negative predictive power. Conclusions. The ISQ is useful, valid, and reliable for assessing perinatal insomnia in Italian women. The Italian version showed equivalent properties to the original version.

Introduction: This study aims to describe the translation and adaptation of the European Portuguese Clinical Frailty Scale and assess its convergent validity and test-retest reliability.Material and Methods: This validation study included a sample of elderly people admitted in two convalescence units from the National Network of Integrated Continuous Care in Northern Portugal and followed in two outpatient clinics of social solidarity institutions. Convergent validity of the scale was evaluated, against Tilburg Frailty Indicator. Test-retest reliability, sensitivity and specificity were assessed.Results: Overall, 51 patients were included (mean age = 78 years old). The Clinical Frailty Scale identified 43.1% patients with frailty. Kappa values for test-retest reliability (non-frail/frail) was 1.00. The intraclass correlation coefficient for the 9-point total scale was 0.999. A correlation between Clinical Frailty Scale and Tilburg Frailty Indicator was also found (rs = 0.683; p < 0.001). The Cohen’s kappa coefficient was 0.423 in the agreement analysis between these scales. The results for sensitivity and specificity defined that 62.0% of patients were true positives and 81.8% true negatives. The scale accuracy determined by the receiver operating characteristics curve analysis was 0.782.Discussion: This scale showed an excellent test-retest reliability. Robust results on convergent validity were also achieved, with a moderate correlation and agreement with the Tilburg Frailty Indicator, showing good sensitivity and accuracy, as well as high specificity.Conclusion: This version has an excellent test-retest reliability and good convergent validity, and is both a reliable and valid test for application in clinical practice for assessing Portuguese elderly population admitted in convalescence units and outpatient clinics.
