Evaluation of measurement properties of health-related quality of life instruments for burns: A systematic review

BACKGROUND: Health-related quality of life (HRQL) is a key outcome in the evaluation of burn treatment. Health-related quality of life instruments with robust measurement properties are required to provide high-quality evidence to improve patient care. The aim of this review was to critically appraise the measurement properties of HRQL instruments used in burns. METHODS: A systematic search was conducted in Embase, MEDLINE, CINAHL, Cochrane, Web of Science, and Google scholar to reveal articles on the development and/or validation of HRQL instruments in burns. Measurement properties were assessed using the Consensus-based Standards for the selection of health Measurement Instruments methodology. A modified Grading of Recommendations, Assessment, Development, and Evaluation analysis was used to assess risk of bias (prospero ID, CRD42016048065). RESULTS: Forty-three articles covering 15 HRQL instruments (12 disease-specific and 3 generic instruments) were included. Methodological quality and evidence on measurement properties varied widely. None of the instruments provided enough evidence on their measurement properties to be highly recommended for routine use; however, two instruments had somewhat more favorable measurement properties. The Burn-Specific Health Scale-Brief (BSHS-B) is easy to use, widely accessible, and demonstrated sufficient evidence for most measurement properties. The Brisbane Burn Scar Impact Profiles were the only instruments with high-quality evidence for content validity. CONCLUSION: The Burn Specific Health Scale-Brief (burn-specific HRQL) and the Brisbane Burn Scar Impact Profile (burn scar HRQL) instruments have the best measurement properties. There is only weak evidence on the measurement properties of generic HRQL instruments in burn patients. Results of this study form important input to reach consensus on a universally used instrument to assess HRQL in burn patients. LEVEL OF EVIDENCE: Systematic review, level III

Measuring vincristine-induced peripheral neuropathy in children with cancer: validation of the Dutch pediatric–modified Total Neuropathy Score

Purpose: The aims were to evaluate the construct validity and reliability of the Dutch version of the pediatric-modified Total Neuropathy Score (ped-mTNS) for assessing vincristine-induced peripheral neuropathy (VIPN) in Dutch pediatric oncology patients aged 5–18 years. Methods: Construct validity (primary aim) of the ped-mTNS was determined by testing hypotheses about expected correlation between scores of the ped-mTNS (range: 0–32) and the Common Terminology Criteria for Adverse Events (CTCAE) (range: 0–18) for patients and healthy controls and by comparing patients and controls regarding their total ped-mTNS scores and the proportion of children identified with VIPN. Inter-rater and intra-rater reliability and measurement error (secondary aims) were assessed in a subgroup of study participants. Results: Among the 112 children (56 patients and 56 age- and gender-matched healthy controls) evaluated, correlation between CTCAE and ped-mTNS scores was as expected (moderate (r = 0.60)). Moreover, as expected, patients had significantly higher ped-mTNS scores and more frequent symptoms of VIPN compared with controls (both p <.001). Reliability as measured within the intra-rater group (n = 10) (intra-class correlation coefficient (ICCagreement) = 0.64, standard error of measurement (SEMagreement) = 2.92, and smallest detectable change (SDCagreement) = 8.1) and within the inter-rater subgroup (n = 10) (ICCagreement = 0.63, SEMagreement = 3.7, and SDCagreement = 10.26) indicates insuffi

Factor structure of Guy's Neurological Disability Scale in a sample of Dutch patients with multiple sclerosis

Background: Guy's Neurological Disability Scale (GNDS) is designed to assess disability (i.e. activity limitations) in patients with multiple sclerosis. It contains 12 functional domains, each indicating a level of disability. Four domain scores and a total score can be calculated.Objective: The aim of this study was to evaluate the structural validity of the GNDS in a Dutch population who were definitely diagnosed as having multiple sclerosis.Methods: Data of 974 patients were available. The structural validity of the GNDS was evaluated by confirmatory item factor analysis (CIFA). Two first-order models and two bifactor models were investigated.Results: The best fitted model was a bifactor model with a general factor underlying all items, and 10 items loading on 3 group factors. Cronbach's alpha on the general factor (0.78) and on the group factor spinal-plus (0.74) were satisfying. Cronbach's alpha on the group factors mental (0.56) and bulbar (0.48) were low. Reliability based on CIFA was 0.85.Conclusion: Results showed a clear factor structure of the GNDS. It justifies the use of the total score of the GNDS. In addition, three sub-scale scores could be used. © SAGE Publications 2011

A Scoping Review on Outcomes and Outcome Measurement Instruments in Rehabilitative Interventions for Patients with Haematological Malignancies Treated with Allogeneic Stem Cell Transplantation

Rationale: Allogeneic hematopoietic stem cell transplantation (HSCT) is associated with increased treatment-related mortality, loss of physical vitality, and impaired quality of life. Future research will investigate the effects of multidisciplinary rehabilitative interventions in alleviating these problems. Nevertheless, published studies in this field show considerable heterogeneity in selected outcomes and the outcome measurement instruments used. The purpose of this scoping review is to provide an overview of the outcomes and outcome measurement instruments used in studies examining the effects of rehabilitative interventions for patients treated with allogeneic HSCT. Methods: We conducted a scoping review that included randomized controlled trials, pilot studies, and feasibility studies published up to 28 February 2022. Results: We included n = 39 studies, in which n = 84 different outcomes were used 227 times and n = 125 different instruments were used for the measurements. Conclusions: Research in the field of rehabilitation for patients with haematological malignancies treated with allogeneic HSCT is hampered by the excess outcomes used, the inconsistent outcome terminology, and the inconsistent use of measurement instruments in terms of setting and timing. Researchers in this field should reach a consensus with regard to the use of a common terminology for the outcomes of interest and a homogeneity when selecting measurement instruments and measurement timing methods. © 2022 by the authors

Improving the quality and applicability of the Dutch scales of the communication profile for the hearing impaired using item response theory

Purpose: The aim of this study was to improve the quality and applicability of the 6 Dutch scales of the Communication Profile for the Hearing Impaired (CPHI; Demorest & Erdman, 1986, 1987, 1988) using item response theory (IRT). IRT modeling can produce precise, valid, and relatively brief instruments, resulting in minimal response burden (Edelen & Reeve, 2007). Method: We investigated (a) whether items fit to the graded response model (GRM; Samejima, 1969) using Stone and Zhang's (2003) procedure to test goodness of fit and (b) whether items showed differential item functioning (DIF) with the IRT log-likelihood ratio approach for 5 group variables: gender, age, living arrangement, use of hearing aids, and degree of hearing impairment. We investigated the magnitude of DIF by calculating the maximum difference between expected item scores for subgroups of the group variables of items showing DIF. Results: In a cross-sectional study, 408 consecutive individuals with hearing impairment completed the Dutch CPHI scales. Twelve items were deleted because of misfit to GRMs, 14 items showed uniform DIF, and 2 showed nonuniform DIF. Five items showing DIF were deleted due to large magnitude of DIF. The short form of the Dutch CPHI scales contains 35 items. Conclusions: DIF analyses showed that the short form was relatively free of DIF with respect to the 5 group variables. Hence, there is no need to make adjustments for the calculation of subgroup scores. © American Speech-Language-Hearing Association
