Abstract The purpose of this article was to introduce the reader nature patient‐reported outcome measures (PROMs) and pitfalls in their use. PROMs collect subjective information directly from patient regarding specific or general conditions add clinical functional outcomes, turn unmeasurable qualities into quantitative measures. are questionnaires consisting items: questions statements with predefined response options. items an adequate PROM have been developed by involvement patients...

The knee injury and Osteoarthritis Outcome Score (KOOS), based on the Western Ontario McMaster Universities Index (WOMAC), is widely used to evaluate subjective outcome in anterior cruciate ligament (ACL) reconstructed patients. However, validity of KOOS has not been assessed using Rasch analysis. objective this study was viability as an measure for ACL reconstruction partial credit model. analysis applied 200 questionnaires completed by patients consecutively tested 20 weeks after...

The aim was to provide an overview of the different statistical methods for validation patient‐reported outcome measures, ranging from simple available in all software packages advanced models that require specialized software. A non‐technical summary classical test theory (CTT) and modern (MTT) is provided. Specifically, confirmatory factor analysis, item response theory, Rasch analysis outlined. One CTT three MTT were used validate two subscales (Symptoms Quality Life) Knee Injury...

Translating patient‐reported outcome measures (PROMs) can alter the meaning of items and undermine PROM's psychometric properties (quantified as cross‐cultural differential item functioning [DIF]). The aim this paper was to present theoretical background for PROM translation, adaptation, validation, assess how PROMs used in sports medicine research have been translated adapted. We also assessed DIF Knee Injury Osteoarthritis Outcome Score (KOOS) across Danish, Norwegian, Swedish versions....

Developing new patient‐reported outcome measures (PROMs) for application in clinical studies can be necessary if an adequate PROM does not exist. For measurement, it is essential that the has face validity (ie, perceived to relevant by clinicians and researchers) high content relevance coverage targeted patient group). The steps needed create PROMs possess a specific condition are described this paper. Face achieved item identification generation through literature review. Content confirmed...

Choosing the most adequate PROM for a study is non‐trivial process. The aim of this was to provide catalogue with analyses content and construct validity PROMs relevant research in sports science, including all published local translations. commonly used were selected from PubMed search “patient reported outcome measures sports”, identifying 439 articles 194 different PROMs. Articles describing development 61 assessed validity, regarding each translations (in total 622 articles) analyzed. A...

A recent COSMIN review found that the Victorian Institute of Sports Assessment–Achilles tendinopathy questionnaire (VISA-A) has flawed construct validity. The objective current study was to assess specifically process how VISA-A constructed and validated, whether Danish version is a valid patient-reported outcome measure (PROM) for measuring perceived impact Achilles tendinopathy. original item generation strategy content validity confirming scaling properties (construct validity) were...

Abstract Results by patient‐reported outcome measures (PROMs) from randomized controlled trials (RCTs) in musculoskeletal research often influence healthcare strategies. We aimed to evaluate which extent these RCTs use adequate PROMs, and how this influences the results conclusions. identified of sports relevance with PROMs as primary outcomes published 13 preselected journals between January 1, 2008, November 2019; all regularly publish research. Five have a high impact factor (>15),...

The benefit of anterior cruciate ligament ( ACL ) reconstruction has been questioned based on patient‐reported outcome measures PROMs ). Valid interpretation such results requires confirmation the psychometric properties PROM . R asch analysis is gold standard for validation , yet used have not validated using analysis.

In Brief The objective of the study was to investigate gait symmetry in transfemoral amputees using a hydraulic- and microprocessor-controlled knee prosthesis. An A-B design with repeated measurements chosen, were carried out at prosthetics/orthotics rehabilitation center. Nine unilateral C-Leg bearing participated study, whom five subjects completed study. Three-dimensional inverse dynamic analysis performed on each subject. Each subject then fitted 3R60 After 1-week acclimation period,...

Patient-related outcome measures (PROMs) are commonly used to gauge treatment effects in patients with anterior cruciate ligament (ACL) deficiency. Valid of specific conditions depend on relevant item content. While content can be derived either from clinicians (face validity) or patients, relevance and comprehensiveness only confirmed by the patient (content validity). Focus group single interviews were conducted patients' pre- post-ACL reconstruction order construct a condition-specific...

To use an inadequate patient reported outcome measure (PROM) or a PROM in inappropriate way potentially influences the quality of measurement. The objectives this study were to define potential uses PROMs sports research studies and estimate how often they occur. A consensus group consisting medical researchers, statisticians, psychometricians identified defined irregular applications PROMs. Occurrence these 349 consecutive articles medicine which used as primary outcomes was reviewed. In...

Abstract Aims/hypothesis Valid and reliable patient-reported outcome measures are vital for assessing disease impact, responsiveness to healthcare the cost-effectiveness of interventions. A recent review has questioned ability existing assess hypoglycaemia-related impacts on health-related quality life people with diabetes. This mixed-methods project was designed produce a novel measure in hypoglycaemia: Hypo-RESOLVE QoL. Methods Three studies were conducted diabetes who experience...

Several terms are used to describe changes in PROM scores relation treatments. Whether the change is small, large, or relevant defined different ways, yet these recommend oppose They also calculate necessary number of patients for a study. This article offers theoretical explanation behind responsiveness, minimal important difference (MID), (MIC), (MIREDIF), and threshold clinical importance. It gives instructions on how optimal study calculated. Responses two domains Knee Injury...

Deviations from adequate use and reporting of PROMs may be problematic misleading. The aim this study was to investigate the extent such problems in randomized clinical trials (RCTs). RCTs involving sports medicine research that used as primary outcomes were identified 13 preselected journals. articles reviewed for nine potential related how PROM data had been reported. follows: aggregating subscale scores; combining patient‐reported scores with physical, clinical, or para‐clinical measures;...

The goal was to use classical and modern methods assess measurement properties minimally clinical important difference (MCID) ODI in a cohort patients with chronic low back pain being treated spinal surgery. Summary Background Data. Scores for ODI, EQ-5D, SF-36, leg pain, general rating item from 800 were extracted National Spine Registry (DaneSpine) at baseline...

Health inequality is on the rise due to various social and individual factors. While preventive health checks (PHC) aim counteract inequality, there robust evidence against use of PHC in general practice. It unknown which factors can identify persons who will benefit from interventions that are more beneficial than harmful. Hence, valid screening instruments needed.The this study was assess psychometric properties a questionnaire (SQ-33), targets vulnerable primary care practice...

Choosing the most appropriate patient‐reported outcome measure (PROM) for a clinical study is essential in order to achieve trustworthy results. This choice will depend on (a) objective of and hence research question; (b) theoretical framework, such as World Health Organization's International Classification Functioning, Disability, (ICF); (c) whether there currently PROM that possesses high content validity construct specific patient group objective, if not; (d) decision use suboptimal or...
