Computerized Adaptive Testing for the Berg Balance Scale Improves Measurement Efficiency Without Compromising Precision in People With Stroke.

Objective: The objectives of this study were to confirm the Berg Balance Scale's (BBS) measurement properties and unidimensionality with an item response theory analysis in persons with subacute and chronic stroke and to examine the precision and efficiency of computerized adaptive testing (CAT).

Methods: Data were obtained from 519 ambulatory persons with subacute and chronic stroke in 2 retrospective databases. A principal component analysis (PCA) of residuals was used to evaluate unidimensionality.

Defining a universal measurement unit and scale for gross motor development.

Introduction: The ability of children to accomplish progressively more difficult gross motor tasks follows a predictable sequence that has been well documented as part of development. Current existing instruments were developed independently using classical test theory methods which led to the lack of a universal measurement scale and unit. The purpose of this study was to test a specification equation, anchored to commonly accepted and reproducible tasks in gross motor development, to generate a universal measurement scale and unit of measurement, called the Gross Motor (GM) unit.

The Functional Balance Ability Measure: A Measure of Balance Across the Spectrum of Functional Mobility in Persons Post-Stroke.

Objective: To determine whether the measurement properties of an instrument that combines items from the Berg Balance Scale (BBS) and the Functional Gait Assessment (FGA) called the supports measuring balance across the functional mobility spectrum

Design: Retrospective cohort.

Setting: Item-level data were from an archival research database.

Participants: Ambulatory individuals (N=93, BBS=50 [29-56], FGA=16 [0-30], Fugl-Meyer Assessment of Lower Extremities=27 [14-34], self-selected walking speed=0.

Background: The Neonatal Eating Outcome Assessment determines feeding performance based on the infant's postmenstrual age (PMA).

Objective: To examine item-level measurement properties of this assessment's rating scale.

Methodology: In this retrospective study, Rasch analysis was completed on clinical data from the Neonatal Eating Outcome Assessment for 100 infants (52 preterm and 48 full-term) using Winsteps version 3.

Conditional Minimal Detectable Change for the Cochlear Implant Quality of Life-35 Profile Associated With Improved Functional Abilities 12 Months After Cochlear Implantation.

Importance: It is essential to measure an individual patient's baseline and follow-up abilities to demonstrate changes in clinical outcomes over time. Inherent in this strategy is interpreting whether the measured change is clinically significant and beyond measurement error. Conditional minimal detectable change (cMDC) values are widely used in many disciplines but have rarely been established for outcome measures in otolaryngology or hearing research, and never in cochlear implantation.

Development and Implementation of the Cochlear Implant Quality of Life (CIQOL) Functional Staging System.

Objectives: The purpose of this study is to develop and implement a functional staging system using the Cochlear Implant Quality of Life (CIQOL) framework. The CIQOL-35 Profile was developed and validated following a rigorous research design and found to be more comprehensive and psychometrically sound than previous patient-reported outcome measures (PROMs) applied to adult CI users. However, interpreting the CIQOL-35 Profile (and all PROMs) relative to real-world functioning remains difficult for patients and clinicians, which limits the capacity of PROMs to direct clinical care.

Normative Cochlear Implant Quality of Life (CIQOL)-35 Profile and CIQOL-10 Global Scores for Experienced Cochlear Implant Users from a Multi-Institutional Study.

Objective: Although adult cochlear implant (CI) outcomes have primarily focused on speech recognition scores, the rigorous development of a CI-specific patient-reported outcome measure provides an opportunity for a more comprehensive and ecologically valid approach to measure the real-world functional abilities of adult CI users. Here, we report for the first time normative Cochlear Implant Quality of Life (CIQOL)-35 Profile and global scores and variance for a large, multi-institutional sample of adult CI users.

Study Design: Cross-sectional study design.

Revisiting the Concept of Minimal Detectable Change for Patient-Reported Outcome Measures.

Interpreting change is a requisite component of clinical decision making for physical therapists. Physical therapists often interpret change using minimal detectable change (MDC) values. Current MDC formulas are informed by classical test theory and calculated with group-level error data.

Examining the Clinical Utility of the Brief Interview for Mental Status.

The Brief Interview for Mental Status (BIMS) is used to identify delirium and needed supports in patients living in skilled nursing facilities (SNFs) and long-term care facilities (LTCFs). We analyzed 3,537,404 patients discharged from acute hospitals to SNFs or LTCFs with factor and Rasch analyses to examine the clinical utility of the BIMS. More than 40% of the sample had maximum scores, indicating a ceiling effect.

Effect of novel training to normalize altered finger force direction post-stroke: study protocol for a double-blind randomized controlled trial.

Background: Functional task performance requires proper control of both movement and force generation in three-dimensional space, especially for the hand. Control of force in three dimensions, however, is not explicitly treated in current physical rehabilitation. To address this gap in treatment, we have developed a tool to provide visual feedback on three-dimensional finger force.

Concomitant sensory stimulation during therapy to enhance hand functional recovery post stroke.

Background: Post-stroke hand impairment is prevalent and persistent even after a full course of rehabilitation. Hand diminishes stroke survivors' abilities for activities of daily living and independence. One way to improve treatment efficacy is to augment therapy with peripheral sensory stimulation.

Using Measurement to Highlight Occupational Therapy's Distinct Value.

Traditional measurement approaches in health care focus on group data, virtually ignoring the individual client. To demonstrate the distinct value of occupational therapy, we need a measurement model that focuses on the person and generates outputs to inform daily practice. Traditional methods of establishing norms and predictive validity do not inform the development of interventions and goal setting.

Validity and reliability of the Cochlear Implant Quality of Life (CIQOL)-35 Profile and CIQOL-10 Global instruments in comparison to legacy instruments.

Objective: Validated and reliable patient-reported outcome measures (PROMs) may provide a comprehensive and accurate assessment of the real-world experiences of cochlear implant (CI) users and complement information obtained from speech recognition outcomes. To address this unmet clinical need, the Cochlear Implant Quality of Life (CIQOL)-35 Profile instrument and CIQOL-10 Global measure were developed according to the Patient-Reported Outcomes Information System (PROMIS) and COnsensus-based Standards for the Selection of health status Measurement INstruments (COSMIN) guidelines. The CIQOL-35 Profile consists of 35 items in six domain constructs (communication, emotional, entertainment, environment, listening effort, and social) and the CIQOL-10 Global contains 10 items that provide an overall CIQOL score.

Measurement Precision and Efficiency of Computerized Adaptive Testing for the Activities-specific Balance Confidence Scale in People With Stroke.

Objective: Administrative burden often prevents clinical assessment of balance confidence in people with stroke. A computerized adaptive test (CAT) version of the Activities-specific Balance Confidence Scale (ABC CAT) can dramatically reduce this burden. The objective of this study was to test balance confidence measurement precision and efficiency in people with stroke with an ABC CAT.

Rasch Analysis of the Activities-Specific Balance Confidence Scale in Individuals Poststroke.

Objective: To examine the psychometric properties of the Activities-specific Balance Confidence (ABC) scale using Rasch analysis for individuals poststroke.

Design: Retrospective cohort.

Setting: Data was extracted from the Locomotor Experience Applied Post-Stroke phase 3, multisite, randomized controlled clinical trial.

Piloting an empirical approach to link the international classification of functioning, disability, and health to job demand classification.

Background: The Social Security Administration has a thorough disability claims process, though one goal is to process claims more efficiently. This pilot described the creation and trial of a web-based tool to assist this process.

Objective: To empirically link the International Classification of Functioning, Disability and Health (ICF) model to the Occupational Information Network (O*NET) with a self-reported activity measure (physical domain).

Cochlear Implant Quality of Life (CIQOL): Development of a Profile Instrument (CIQOL-35 Profile) and a Global Measure (CIQOL-10 Global).

Purpose Valid, reliable, and efficient patient-reported outcome measures are needed to quantify quality of life (QOL) outcomes after cochlear implantation to supplement information obtained from performance-based outcomes. We previously developed the Cochlear Implant Quality of Life (CIQOL) item bank to serve as the source of items for subsequent instruments. This study reports the development and psychometric properties for 2 of these new instruments, the CIQOL-35 Profile and the CIQOL-10 Global.

Association of Demographic and Hearing-Related Factors With Cochlear Implant-Related Quality of Life.

Importance: Only limited evidence is available describing the contribution of patient-related factors to quality of life in adults with cochlear implants.

Objective: Assess the association between demographic, hearing-related, and cochlear implant-related factors and quality of life by using a new Cochlear Implant Quality of Life (CIQOL) item bank, which was developed to meet rigorous psychometric standards.

Design, Setting, And Participants: Multicenter cross-sectional study of adults 18 to 89 years of age who had at least 1 year of cochlear implant use and who were recruited through a consortium of 20 cochlear implant centers in the United States.

Multidimensionality of the PROMIS self-efficacy measure for managing chronic conditions.

Purpose: This study investigated the PROMIS Self-Efficacy Measure for Managing Chronic Conditions (PROMIS-SE) domain distributions and examined the factor structure of the PROMIS-SE.

Methods: A total of 1087 individuals with chronic conditions participated in this study. PROMIS-SE's item banks and two short forms (eight-item and four-item) measuring five behavioral domains (daily activities(DA), Emotions(EM), medications and treatments(MT), social interactions(SS), and Symptoms(SX)) were examined.

Development of the Cochlear Implant Quality of Life Item Bank.

Objectives: Functional outcomes following cochlear implantation have traditionally been focused on word and sentence recognition, which, although important, do not capture the varied communication and other experiences of adult cochlear implant (CI) users. Although the inadequacies of speech recognition to quantify CI user benefits are widely acknowledged, rarely have adult CI user outcomes been comprehensively assessed beyond these conventional measures. An important limitation in addressing this knowledge gap is that patient-reported outcome measures have not been developed and validated in adult CI patients using rigorous scientific methods.

KOOS-JR Demonstrates Psychometric Limitations in Measuring Knee Health in Individuals After ACL Reconstruction.

Background: Measurement properties of the short form of the Knee injury and Osteoarthritis Outcome Score (KOOS-JR) are not established in individuals after anterior cruciate ligament reconstruction (ACLR). The purpose of this study was to determine the extent to which the KOOS-JR measures the construct of knee health in individuals post-ACLR using Rasch analysis.

Hypothesis: The KOOS-JR will fit the Rasch model, but significant ceiling effects will be present.

Measuring the interference of pain on daily life in persons with spinal cord injury: A Rasch-validated subset of items from the Brief Pain Inventory interference scale.

Background/aim: Up to 60% of individuals report chronic pain after traumatic spinal cord injury (SCI). Measurement of the degree to which pain interferes with activities and emotions can provide valuable clinical insights with implications for pain management interventions. One questionnaire that can be used to quantify the impact of pain is the Brief Pain Inventory (BPI) interference scale, a seven-item self-report assessment.

Comparing Disability Levels for Community-dwelling Adults in the United States and the Republic of Korea using the Rasch Model.

This study compared disability levels between community-dwelling adults in the United States and South Korea using two national surveys of the United States and Korean National Health and Examination Survey (NHANES and KNHANES). The Rasch common-item equating method was used to create the same measurement framework and compared average disability levels. The disability levels between the two countries were estimated using the current disability estimation method (percentage of people having disability based on a single question).
