Item bank development, calibration and validation for patient-reported outcomes in female urinary incontinence.

ABSTRACT: PURPOSE:Current patient-reported outcomes for female urinary incontinence (UI) are limited by their inability to be tailored. Our objective is to describe the development and field testing of seven item banks designed to measure domains identified as important UI in females (UIf). We also describe the calibration and validation properties of the UIf-item banks, which allow for more efficient computerized adaptive testing (CAT) in the future. METHODS:The UIf-measures included 168 items covering seven domains: Stress UI (SUI), overactive bladder (OAB), urinary frequency, physical, social and emotional health impact and adaptation. Items underwent rigorous qualitative development and psychometric testing across two sites. Items were calibrated using item response theory and evaluated for internal consistency, construct validity and responsiveness. RESULTS:A total of 750 women (249 SUI, 249 OAB and 252 mixed UI) participated. Mean age was 55 ± 14 years, and 23 % were Hispanic and 80 % white. In addition to face and content validity, the measures demonstrated good internal consistency (coefficient alpha 0.92-0.98) and unidimensionality. There was evidence for construct validity with moderate-to-strong correlations with the UDI (r's ? 0.6) and IIQ (r's = ?0.6) scales. The measures were responsive to change for SUI treatment (paired t test p < .001, ES range 1.3-2.9; SRM range 1.3-2.5) and OAB treatment (paired t test p < .05 for all domains except social health impact and adaptation, ES range 0.3-1.5, SRM range 0.4-1.0). The measures were responsive based on concurrent changes with the UDI and IIQ (p < 0.05). CAT versions were developed and pilot-tested. CONCLUSIONS:The UIf-item banks demonstrate good psychometric characteristics and are a sufficiently valid set of customizable tools for measuring UI symptoms and life impact.

Project description:Lower limb orthoses (LLOs) are externally-applied leg braces that are designed to improve or maintain mobility in people with a variety of health conditions that affect lower limb function. Clinicians and researchers are therefore often motivated to measure LLO users' mobility to select or assess the effectiveness of these devices. Patient-reported outcome measures (PROMs) can provide insights into important aspects of a LLO user's mobility for these purposes. However, few PROMs are available to measure mobility of LLO users. Those few that exist have issues that may limit their clinical or scientific utility. The objective of this study was to create a population-specific item bank for measuring mobility of LLO users. Previously-developed candidate items were administered in a cross-sectional study to a large national sample of LLO users. Responses from study participants (n = 1036) were calibrated to a graded response statistical model using Item Response Theory methods. A set of 39 items was found to be unidimensional, locally independent, and function without bias due to characteristics unrelated to mobility. The set of final calibrated items, termed the Orthotic Patient-Reported Outcomes-Mobility (OPRO-M) item bank, was evaluated for initial evidence of convergent, divergent, and known groups construct validity. OPRO-M was strongly correlated with existing PROMs designed to measure aspects of physical function. Conversely, OPRO-M was weakly correlated with PROMs that measured unrelated constructs, like sleep disturbance and depression. OPRO-M also showed an ability to differentiate groups with expected mobility differences. Two fixed-length short forms were created from the OPRO-M item bank. Items on the short forms were selected based on statistical and clinical criteria. Collectively, results from this study indicate that OPRO-M can effectively measure mobility of LLO users, and OPRO-M short forms can now be recommended for use in routine clinical practice and research studies.

Project description:BackgroundLimitations in physical functioning are a big concern especially for patients with chronic or musculoskeletal diseases. Therefore, physical functioning is often used as a core outcome of treatments. The generic patient-reported outcomes information system (PROMIS) physical function (PF) item bank has shown potential to measure PF with better precision, interpretability and lower respondent burden compared with traditional patient-reported outcome measures. This study provides an overview of the current evidence on the quality of the measurement properties of the translated Dutch-Flemish PROMIS-PF item bank and its subdomains, and their derived short forms and computer adaptive tests (CATs).MethodsPubMed was searched up to June 17th 2020 for validation studies of Dutch-Flemish PROMIS-PF in Dutch and Flemish adults. Quality assessment of the included studies was conducted using the COSMIN Risk of bias checklist. The COSMIN criteria for good measurement properties were used to judge the results of the studies, which were adjusted and added to where needed for this review, in the context of IRT instruments and item banks. The quality of evidence was summarized for each measurement property based on the Grading of Recommendation Assessment, Development, and Evaluation (GRADE) approach.ResultsEleven studies were included, evaluating the PROMIS-PF item bank, the Upper Extremity (UE) subdomain, and/or their derived short forms and CATs in different clinical populations. There is evidence for sufficient structural validity, measurement precision, construct validity, and cross-cultural validity of the Dutch-Flemish PROMIS-PF item bank. The upper extremity subdomain item bank shows high quality evidence for structural validity and measurement precision. Content validity of these item banks has not been thoroughly demonstrated in a Dutch-Flemish population. Furthermore, the derived instruments have far less robust evidence: there are fewer validation studies available and none examined their performance as stand-alone administered instruments.ConclusionsThe first studies into the Dutch-Flemish PROMIS-PF item bank and the UE subdomain show promising results, with especially high quality evidence for sufficient structural validity and measurement precision. However, more studies, and with higher methodological quality, are needed to study the instruments derived from these item banks. These studies should also evaluate content validity, reliability and responsiveness.

Project description:PurposeThis study aimed to validate the PROMIS Pediatric item bank v2.0 Peer Relationships and compare reliability of the full item bank to its short form, computerized adaptive test (CAT) and the social functioning (SF) subscale of the Pediatric Quality of Life Inventory (PedsQL™).MethodsChildren aged 8-18 (n = 1327), representative of the Dutch population completed the Peer Relationships item bank. A graded response model (GRM) was fit to the data. Structural validity was assessed by checking item-fit statistics (S-X2, p < 0.001 = misfit). For construct validity, a moderately strong correlation (> 0.50) was expected between Peer Relationships and the PedsQL SF subscale. Cross-cultural DIF between U.S. and NL was assessed using logistic regression, where an item with McFadden's pseudo R2 > 0.02 was considered to have DIF. Percentage of participants reliably measured was assessed using the standard error of measurement (SEM) < 0.32 as a criterion (reliability of 0.90). Relative efficiency ((1-SEM2)/nitems) was calculated to compare how well the instruments performed relative to the amount of items administered.ResultsIn total, 527 (response rate: 39.7%) children completed the PROMIS v2.0 Peer Relationships item bank (nitems = 15) and the PedsQL™ (nitems = 23). Structural validity of the Peer Relationships item bank was sufficient, but one item displayed misfit in the GRM model (S-X2 < 0.001); 5152R1r ("I played alone and kept to myself"). The item 733R1r ("I was a good friend") was the only item that displayed cross-cultural DIF (R2 = 0.0253). The item bank correlated moderately high (r = 0.61) with the PedsQL SF subscale Reliable measurements were obtained at the population mean and > 2SD in the clinically relevant direction. CAT outperformed all other measures in efficiency. Mean T-score of the Dutch general population was 46.9(SD 9.5).ConclusionThe pediatric PROMIS Peer Relationships item bank was successfully validated for use within the Dutch population and reference data are now available.
