Validation of the Activities-Specific Balance Confidence Scale With 5-Option Response Format in Slovene Lower-Limb Prosthetic Users

ObjectiveTo examine the psychometric properties of the Activities-specific Balance Confidence (ABC) scale administered in the Slovene version with a simplified 5-option response format (ABC-5/SLO) using Rasch analysis.DesignMethodological research on data gathered in a cross-sectional study.SettingOutpatient university rehabilitation clinic.ParticipantsA convenience sample of adults with unilateral lower-limb amputation (N=138; 75% men) longer than 6 months who regularly wear a prosthesis.InterventionNot applicable.Main Outcome MeasuresWe evaluated functioning of rating scale categories, internal construct validity, reliability indices, and dimensionality using the ABC-5/SLO (0=no confidence to 4=complete confidence).ResultsThe ABC-5/SLO rating scale fulfilled the category functioning criteria. All items fit the underlying scale construct (balance confidence) except item 8 (“walk outside the house to a car parked in the driveway”), which was overfitting. The person abilities-item difficulty matching (targeting) was good. The person separation reliability was .92, and the item separation reliability was .99. Analysis of the standardized Rasch residuals showed the scale’s unidimensionality and absence of high item dependency (residual correlations, <.30). The correlation between the ABC-5/SLO and the Prosthetic Mobility Questionnaire (Rasch measures) was high (ρ=.84), as expected. Minor signs of item redundancy were found.ConclusionsThe simplified ABC-5/SLO scale is a valid and reliable measure of balance confidence for individuals with lower-limb amputation. It is possible to transform the ordinal summed raw scores of the ABC-5/SLO into interval-level measurements using a nomogram.     

Inpatient Rehabilitation Quality of Care From the Patient’s Perspective: Effect of Data Collection Timing and Patient Characteristics

ObjectiveTo compare, by collection time and patient characteristics, inpatient rehabilitation quality measure scores calculated using patient-reported data.DesignCohort study of rehabilitation inpatients with neurologic conditions who reported their experience of care and pain status at discharge and 1month after discharge.SettingTwo inpatient rehabilitation facilities (IRFs).ParticipantsPatients with neurologic conditions (N=391).InterventionsNot applicable.Main Outcome MeasuresWe calculated 18 quality measure scores using participants’ responses to 55 experience of care and health status questions addressing communication, support and encouragement, care coordination, discharge information, goals, new medications, responsiveness of staff, cleanliness, quietness, pain management, care transitions, overall hospital rating, willingness to recommend, and pain.ResultsOf the 391 participants reporting at discharge, 277 (71%) also reported postdischarge after multiple attempts by e-mail, mail, and telephone. Discharge experience of care quality scores ranged from 25% (responsiveness of hospital staff) to 75% (willingness to recommend hospital); corresponding postdischarge scores were 32% to 87%, respectively. Five of the 16 experience of care quality scores increased significantly between discharge and postdischarge. The percentage of participants reporting high pain levels at discharge did not change across time periods. Patients with less education, older age, higher motor and cognitive function, and those who were not Hispanic or black had more favorable quality measure scores.ConclusionPatients’ experience of care responses tended to be more favorable after discharge compared to discharge, suggesting that survey timing is important. Responses were more favorable for patients with selected characteristics, suggesting the possible need for risk adjustment if patient-reported quality measure scores are compared across IRFs.     

Brain Injury Functional Outcome Measure (BI-FOM): A Single Instrument Capturing the Range of Recovery in Moderate-Severe Traumatic Brain Injury

ObjectiveTo develop a measure of global functioning after moderate-severe TBI with similar measurement precision but a longer measurement range than the FIM.DesignPhase 1: retrospective analysis of 5 data sets containing FIM, Disability Rating Scale, and other assessment items to identify candidate items for extending the measurement range of the FIM; Phase 2: prospective administration of 49 candidate items from phase 1, with Rasch analysis to identify a unidimensional scale with an extended range.SettingSix TBI Model System rehabilitation hospitals.ParticipantsIndividuals (N=184) with moderate-severe injury recruited during inpatient rehabilitation or at 1-year telephone follow-up.InterventionsParticipants were administered the 49 assessment items in person or via telephone.Main Outcome MeasuresItem response theory parameters: item monotonicity, infit/outfit statistics, and Factor 1 variance.ResultsAfter collapsing misordered rating categories and removing misfitting items, we derived the Brain Injury Functional Outcome Measure (BI-FOM), a 31-item assessment instrument with high reliability, greatly extended measurement range, and improved unidimensionality compared with the FIM.ConclusionsThe BI-FOM improves global measurement of function after moderate-severe brain injury. Its high precision, relative lack of floor and ceiling effects, and feasibility for telephone follow-up, if replicated in an independent sample, are substantial advantages.     

Reliability and Validity of the Lower Extremity Motor Activity Log for Measuring Real-World Leg Use in Adults With Multiple Sclerosis

ObjectivesTo determine the test-retest reliability and validity of the Lower Extremity Motor Activity Log (LE-MAL) for assessing LE use in the community in adults with multiple sclerosis (MS).DesignProspective analysis of measures conducted by trained examiners.SettingParticipants were evaluated by telephone on several measures of LE use.ParticipantsAdults with MS (N=43).InterventionsNot applicable.Main Outcome MeasuresThe LE-MAL has 3 subscales (Assistance, Functional Performance, and Confidence). It was administered twice, at least 2 weeks apart. The Multiple Sclerosis Walking Scale (MSWS-12), Patient Determined Disease Steps (PDDS), and Mobility Scale were only administered during the first call.ResultsThe test-retest reliability of the composite and the 3 subscale LE-MAL scores were high (intraclass correlation, >0.94). The composite and subscale LE-MAL scores were strongly correlated with the MSWS-12, PDDS, and Mobility Scale scores (r=–0.56 to –0.77; P<.001).ConclusionThis initial study suggests that the LE-MAL reliably and validly measures LE use in the community in adults with MS.     

Prospective Blinded Evaluation of Patient-Physician Agreement Using the Summary Outcome Determination (SOD) Score

ObjectiveTo determine whether the Summary Outcome Determination (SOD) score demonstrates a high level of physician-patient agreement in a prospective setting with multiple raters.Patients and MethodsFor this study, 100 patients who were being evaluated at various intervals following shoulder or elbow surgery were prospectively enrolled from May 30, 2017, through August 31, 2017. The patients’ attending physicians and a member of their team (physician assistant, resident, fellow, medical student) assigned categorical and numerical SOD scores while blinded to the scores given by each other. All scores were analyzed among raters, assessing internal consistencies, agreement, and reliability.ResultsThe mean follow-up (interval between surgery and completion of the survey) was 31 months, with a range of 1 to 220 months. The intraclass correlation coefficient for patient and physician numerical scores was excellent at 0.82. The weighted κ value for categorical scores was 0.64. Bland-Altman analysis revealed low average discrepancy at 0.6 with a 95% CI of −3.3 to 4.5. The Cronbach α value was 0.94, indicating strong internal validity. The categorical physician-patient agreement occurred within one category 96% of the time.ConclusionThis study found that the SOD score has strong agreement with excellent intraclass correlation coefficient and weighted κ values, indicating substantial agreement, reproducibility (shown by low average error), and strong internal validity. With promising results in the prospective setting, the SOD score was found to be an easy to use outcome measure with reliable agreement between patient and physician. This score has potential to be a metric revealing the “value” of a specific surgical intervention.

Validation of the Spinal Cord Injury–Functional Index for Use in Community-Dwelling Individuals With SCI

ObjectiveTo evaluate the psychometric properties of the Spinal Cord Injury–Functional Index (SCI-FI) instruments in a community-dwelling sample.DesignCross-sectional study.SettingCommunity setting.ParticipantsIndividuals (N=269) recruited from 6 SCI Model Systems sites.InterventionsNot applicable.Main Outcome MeasuresParticipants completed computer adaptive test and short form versions of 4 SCI-FI/Capacity (C) banks (ie, Ambulation, Basic Mobility, Fine Motor, Self-Care) and 1 SCI-FI/Assistive Technology (AT) bank (Wheelchair Mobility) at baseline and after 2 weeks. The Self-Report Functional Measure (SRFM) and the clinician-rated motor FIM were used to evaluate evidence of convergent validity.ResultsPearson correlations, intraclass correlation coefficients, minimal detectable change, and Bland-Altman plots supported the test-retest reliability of the SCI-FI instruments. Correlations were large with the SRFM (.69-.89) and moderate-to-large for the FIM instrument (.44-.64), supporting convergent validity. Known-groups validity was demonstrated by a significant main effect of injury level on all instruments and a main effect of injury completeness on the SCI-FI/C instruments. A ceiling effect was detected for individuals with incomplete paraplegia on the Fine Motor/C and Self-Care/C Short Forms.ConclusionFindings support the test-retest reliability, convergent validity, and known-groups validity of the SCI-FI/C instruments and the SCI-FI/AT Wheelchair Mobility instruments for use by community-dwelling individuals.     

The Gait Disorientation Test: A New Method for Screening Adults With Dizziness and Imbalance

ObjectiveTo develop and evaluate a new method for identifying gait disorientation due to vestibular dysfunction.DesignThe gait disorientation test (GDT) involves a timed comparison of the ability to walk 6.096 m with eyes open versus eyes closed. In this prospective study, participants were grouped based on vestibular function. All participants completed a clinical examination, self-report- and performance-based measures relevant to vestibular rehabilitation, and the tasks for the GDT. Vestibular-impaired participants underwent the criterion standard, videonystagmography and/or rotational chair testing.SettingAmbulatory clinic, tertiary referral center.ParticipantsParticipants (N=40) (20 vestibular-impaired, 30 women, 49.9±16.1years old) were enrolled from a convenience/referral sample of 52 adults.Main Outcome and Measure(s)We determined test-retest reliability using the intraclass correlation coefficient model 3,1; calculated the minimal detectable change (MDC); examined concurrent validity through Spearman correlation coefficients; assessed criterion validity with the area under the curve (AUC) from receiver operator characteristic analysis; and computed the sensitivity, specificity, diagnostic odds ratio (DOR), likelihood ratios for positive (LR+) and negative (LR?) tests, and posttest probabilities of a diagnosis of vestibulopathy. The 95% confidence interval demonstrates measurement uncertainty.ResultsTest-retest reliability was 0.887 (0.815, 0.932). The MDC was 3.7 seconds. Correlations with other measures ranged from 0.59 (0.34, 0.76) to ?0.85 (?0.92, ?0.74). The AUC was 0.910 (0.822, 0.998), using a threshold of 4.5 seconds. The sensitivity and specificity were 0.75 (0.51, 0.91) and 0.95 (0.75, 1), respectively. The DOR=57 (6, 541.47), LR+ =15 (2.18, 103.0), and LR? =0.26 (0.12, 0.9). Positive posttest probabilities were 89%-94%.Conclusions and RelevanceThe GDT has good reliability, excellent discriminative ability, strong convergent validity, and promising clinical utility.     

Rasch Analysis of Postconcussive Symptoms: Development of Crosswalks and the Brain Injury Symptom Scale

ObjectiveThe first aim of this study was to develop a Rasch-based crosswalk between 2 postconcussive symptom measures, the Neurobehavioral Symptom Inventory (NSI) and the Rivermead Postconcussive Symptom Questionnaire (RPQ). The second goal was to utilize Rasch analysis to formulate a new proposed scale containing the best theoretical and psychometric items.DesignProspective cohort observational study.SettingThree acute inpatient rehabilitation hospitals in the United States.ParticipantsCommunity-dwelling persons (N=497) who were previously hospitalized and were diagnosed with mild to severe traumatic brain injury. Participants were (1) 18-64 years old; (2) could give informed consent; (3) able to complete study measures in English; (4) did not have an interfering medical or psychiatric condition.InterventionsNot applicable.Main Outcome MeasuresNSI, RPQ.ResultsRasch analysis revealed 4 subdimensions across the 2 scales: cognitive, affective, physical, and visual. Crosswalk tables were generated for the first 3. Visual items were too few to generate a crosswalk. Iterative Rasch analysis produced a new scale with items rated from none to severe including the best items in each of these dimensions.ConclusionsThe NSI and RPQ have considerable overlap and measure the same overarching constructs. Crosswalk tables may be helpful for clinicians and researchers to convert scores from 1 measure to the other. A more psychometrically sound scale, the Brain Injury Symptom Scale, composed of items from the NSI and RPQ, is proposed and will need further validation.     

Using the ICF to Identify Contextual Factors That Influence Participation of Persons With Deafblindness

ObjectiveTo identify and describe the contextual factors that influence the participation of people with deafblindness in India.DesignQualitative study, using directed content analysis approach and the International Classification of Functioning, Disability and Health (ICF) as a framework to analyze the data.SettingCommunity and social participation settings.ParticipantsCommunity-dwelling individuals with deafblindness (N=16). Age ranges from 18-45 years.InterventionsNot applicable.Main Outcome MeasuresPersonal and environmental factors that influence the participation of individuals with deafblindness using the ICF framework.ResultsResults indicate that the age of onset and nature of impairment (deafblindness) and willingness to explain the condition (functional consequences of deafblindness) emerged as important personal factors. Access to resources such as assistive technology, social support, and deafblind-specific services were found to be enablers of participation. Lack of services, systems, and policies specific to deafblindness along with negative societal attitude toward disability were highly perceived environmental barriers that influence participation of people with deafblindness in India.ConclusionsProfessionals must acknowledge aspects of the environment in conducting assessments and delivering interventions and understand the dynamic interactions between environment of the individual and his/her concurrent vision and hearing impairments. Approaches to enable participation require rehabilitation professionals to work with those with deafblindness to advocate for removal of environmental barriers and ensure provision of appropriate resources from the government to facilitate their participation. Social policy and government must ensure emphasis on awareness about deafblindness, access to deafblind-specific services, positive societal attitude, and opportunities for full participation for people with deafblindness in society.     

Comorbidities in Patients With End-Stage Knee OA: Prevalence and Effect on Physical Function

ObjectiveTo investigate the prevalence of comorbidities and their effect on physical function, quality of life (QOL), and pain, in patients with end-stage knee osteoarthritis (OA).DesignA cross-sectional study.SettingA rehabilitation facility at university hospital.ParticipantsPatients (N=577; 503 women and 74 men) diagnosed with end-stage knee OA between October 2013 and June 2018.InterventionNot applicable.Main Outcome MeasuresComorbidities were as follows: osteoporosis, presarcopenia, degenerative spine disease, diabetes, and hypertension. All patients completed the following performance-based physical function tests: stair-climbing test (SCT), 6-minute walk test (6MWT), timed Up and Go (TUG) test, and gait analysis. Self-reported physical function and pain were measured using Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) and a visual analog scale (VAS), respectively, and self-reported QOL was measured using EuroQoL 5 dimensions (EQ-5D) questionnaire.ResultsUnivariate analyses revealed that patients with osteoporosis had significantly higher scores in SCT ascent, SCT descent, TUG, WOMAC pain tests, and lower scores in 6MWT, gait speed, and cadence tests than those without osteoporosis. Patients with presarcopenia recorded higher scores in SCT ascent, TUG, EQ-5D, and lower scores in 6MWT and gait speed tests than those without presarcopenia. Patients with degenerative spine disease showed higher scores in WOMAC pain and lower scores in gait speeds than those without degenerative spine disease. Patients with diabetes showed higher scores in SCT ascent than those without diabetes, and patients with hypertension showed lower scores in 6MWT than those without hypertension. After adjusting age, sex, and body mass index, SCT descent retained significant association with osteoporosis, SCT ascent showed independent association with presarcopenia and diabetes, and WOMAC pain revealed significant association with degenerative spine disease.ConclusionThe results confirm associations between comorbidities, performance-based and self-reported physical functions, and QOL in patients with end-stage knee OA.     

Content and Effectiveness of Interventions Focusing on Community Participation Poststroke: A Systematic Review

ObjectiveTo investigate the content and effectiveness of interventions that address poststroke community participation.Data SourcesEMBASE, PsycINFO, PubMed, and Cumulative Index to Nursing and Allied Health (CINAHL) were searched using 3 indexing terms and respective thesaurus: stroke, social participation, and clinical trials. Filters for English, publication dates (January 2001-May 2017), and publication types were used. The search also included checking references from relevant systematic reviews.Study SelectionStudies conducted with adults with stroke, evaluating interventions addressing community participation, having a comparison group, and reporting at least 1 of 3 outcomes (participation, depression, and health-related quality of life) were selected. Retrieved articles were screened by 2 reviewers. After substantial agreement was achieved using interrater reliability, reviewers screened articles independently. Eighteen of 1130 articles were included.Data ExtractionCharacteristics of participants, key elements of intervention, comparator, and results were independently extracted by 2 reviewers. Intervention content was categorized based on 9 categories from the International Classification of Functioning, Disability, and Health Activities and Participation domains. Risk of selection, performance, attrition, and reporting bias were evaluated.Data SynthesisTwo intervention categories were identified: leisure participation and community integration. Three leisure and 4 community integration interventions showed significant group differences favoring the intervention group in the target outcomes. The majority of interventions addressed the leisure, interpersonal relations, and community life categories of International Classification of Functioning, Disability, and Health with few focusing on political life, education, assisting others, and religion.ConclusionsA limited number of studies showed an effect on participation, depression, and health-related quality of life outcomes. There were gaps in intervention content indicating that current community participation interventions fall short in addressing full inclusion and citizenship of people with stroke. Future interventions should focus on civic- and societal-level participation and community activities beyond leisure.     

Validation of the WHOQOL-BREF and Shorter Versions Using Rasch Analysis in Traumatic Brain Injury and Orthopedic Populations

ObjectiveTo use Rasch analysis to validate the World Health Organization Quality of Life-BREF (WHOQOL-BREF) and existing short versions in individuals with traumatic brain injury and orthopedic injuries, with comparisons to a general population group.DesignThe Partial Credit Rasch model was applied to evaluate the WHOQOL-BREF as well as shortened versions using a cross-sectional study design.SettingRegional hospital, and national electoral sample in New Zealand.ParticipantsIndividuals with traumatic brain injury (n=74), individuals with orthopedic injuries (n=114), general population (n=140).InterventionsNone.Main Outcome MeasureWHOQOL-BREF.ResultsThe WHOQOL-BREF met expectations of the unidimensional Rasch model and demonstrated good reliability (person separation index [PSI] =0.82) when domain items were combined into physical-psychological, social, and environmental superitems. Analysis of shorter versions, the EUROHIS-QOL-8 and World Health Organization Quality of Life-5 (WHOQOL-5), indicated overall acceptable fit to the Rasch model and evidence of unidimensionality. The EUROHIS-QOL-8 showed good reliability (PSI=0.81); however, reliability of the WHOQOL-5 (PSI=0.68) was below acceptable standards for group comparisons, in addition to demonstrating poor person-item targeting.ConclusionsThe WHOQOL-BREF and the 8-item EUROHIS-QOL-8 version are both reliable and valid in the assessment of quality of life in both injury and general populations. Ordinal-interval conversion tables published for these validated scales as well as for the WHOQOL-5 can be used to improve precision of assessment. The transformation of ordinal scale scores into an interval measure of health-related quality of life also permits the calculation of a single summary score for the WHOQOL-BREF, which will be useful in a wide range of clinical and research contexts. Further validation work of the WHOQOL-5 is needed to ascertain its psychometric properties.     

Gait Function in Adults Aged 50 Years and Older With Spina Bifida

ObjectiveTo study gait function among individuals with spina bifida (SB) aged 50 years or older.DesignA cross-sectional study conducted in 2017.SettingHome-dwelling participants from all regions in Norway.ParticipantsIndividuals between the ages of 51 and 76 years (N=26; 16 women) categorized as independent walkers (n=9), walkers with aids (n=10) and nonwalkers (n=7).InterventionsNot applicable.Main Outcome MeasuresQuestionnaire, pain assessment, anthropometry, Falls Efficacy Scale International (FES-I), objective gait analysis, 6-minute walk test (6MWT), and timed Up and Go (TUG).ResultsWalking speed correlated with SB severity (ρ=–.59; P=.008). Individuals who walked slower than 0.81 m/s had a higher body mass index (BMI) than those who walked faster (P=.008). Independent walkers walked slower than healthy age-matched walkers (P=.046); spatiotemporal variables showed that this was owing to shorter steps rather than cadence. The mean TUG was 10.6±2.6 seconds in independent walkers and 20.2±6.5 in walkers with aids (P<.01). The mean 6MWT was 504±126 meters in independent walkers and 316±88 in walkers with aids (P<.01). The mean pain intensity (numeric rating scale) was 4.9±2.2 in independent walkers and 4.2±1.6 in walkers with aids, but the difference was not statistically significant. FES-I was significantly lower among independent walkers (mean, 23.6±3.9) than walkers with aids (mean, 31.4±10.0) (P=.042).ConclusionsParticipants commonly experienced an early onset deterioration in gait function, and walking speed was influenced by SB severity and BMI. This highlights the importance of early monitoring and weight management during follow-up for SB.     

Physical Therapy Use,Costs, and Value for Latent Classes of Good vs Poor Outcome in Patients Who Catastrophize About Their Pain Prior to Knee Arthroplasty

ObjectiveTo examine use, costs, and value of physical therapy (PT) among subgroups.DesignWe conducted an observational study of data from a randomized trial of a pain coping skills intervention. Good and poor outcome subgroups were determined based on Western Ontario and McMasters Universities Osteoarthritis Index (WOMAC) Pain and Physical Function scores. The use and costs of PT care as well as changes in WOMAC Pain and Physical Function scores over 4 time periods during a 1-year follow-up were reported. We compared the number of PT visits, total PT costs, and cost per 1-unit improvement in WOMAC scores for the 2 latent subgroups.SettingFive academic medical centers.ParticipantsPatients who catastrophized about their pain prior to knee arthroplasty (N=384).InterventionsPain coping skills training, arthritis education, and usual care.Main Outcome MeasuresThe WOMAC Pain Scale was the primary outcome.ResultsThe value of PT was lower and the cost of PT was higher for poor vs good outcome subgroups beginning 2 months after knee arthroplasty. For example, during the 2- to 6-month period, participants in the poor outcome subgroup incurred a PT cost of $5181.22 per 1-unit improvement in WOMAC Pain compared with $437.87 per 1-unit improvement in WOMAC Pain for the good outcome subgroup (P<.001). From the 6- to 12-month period, WOMAC scores worsened for the poor outcome subgroup, indicating no benefit from PT.ConclusionsPatients in 2 latent classes demonstrated clinically important differences in value of PT. Future research should identify rehabilitation-based interventions that reduce utilization and enhance effectiveness for patients at high risk for poor outcome.     

Association of Therapy Time Per Day With Functional Outcomes and Rate of Recovery in Older Adults After Elective Joint Replacement Surgery

ObjectivesTo explore the association between therapy minutes per length of stay (LOS) day (TMLD), functional outcomes, and rate of functional recovery among older adults after elective hip or knee replacement surgery across postacute (PAC) settings.DesignSecondary analysis of data collected for an observational cohort study from 2005 to 2010.SettingFour inpatient rehabilitation facilities (IRF) and 7 skilled nursing facilities (SNF).ParticipantsAdults aged 65 years or older (N=162) with Medicare fee-for-service insurance and a primary diagnosis of elective hip or knee replacement.InterventionsNot applicable.Main Outcome MeasuresFIM mobility and self-care measures at discharge.ResultsThe TMLD was divided into high, medium, and low categories. Participants were grouped into low, medium, and high gain rate groups based on their average change in mobility and self-care FIM measures per LOS day. Gain rate and TMLD groups were crossmapped to create 9 gain-TMLD groups separately for mobility and self-care. There were no significant differences in admission mobility or self-care measures by gain rate and TMLD trajectory or by facility type (IRF or SNF). TMLD was not significantly associated with discharge mobility measures. Participants in high gain trajectories attained independence with mobility and self-care tasks at discharge regardless of TMLD. Those in low gain trajectories needed supervision or assistance on all mobility tasks. Older age and greater pain at discharge were significantly associated with lower odds of being in the medium or high gain rate groups.ConclusionsFor clinicians and facility managers who must care for patients with constrained resources, the shift to value-based reimbursement for rehabilitation services in PAC settings has reinvigorated the question of whether the duration of therapy provided influences patient outcomes. Three hours of daily therapy after joint replacement surgery may exceed what is necessary for recovery. Postsurgical pain management remains a significant challenge in older adults.     

Positive Beliefs and the Likelihood of Successful Community Discharge From Skilled Nursing Facilities

ObjectivesTo examine the association of patient and direct-care staff beliefs about patients’ capability to increase independence with activities of daily living (ADL) and the probability of successful discharge to the community after a skilled nursing facility (SNF) stay.DesignRetrospective cohort study of SNF patients using 100% Medicare inpatient claims and Minimum Data Set resident assessment data. Linear probability models were used to estimate the probability of successful discharge based on patient and staff beliefs about the patient’s ability to improve in function, as well as patient and staff beliefs together. Estimates were adjusted for demographics, health status, functional characteristics, and SNF fixed effects.ParticipantsFee-for-service Medicare beneficiaries (N=526,432) aged 66 years or older who were discharged to an SNF after hospitalization for stroke, hip fracture, or traumatic brain injury.InterventionsNot applicable.Main Outcome MeasuresSuccessful community discharge (discharged alive within 90d of SNF admission and remaining in the community for ≥30d without dying or health care facility readmission).ResultsPatients with positive beliefs about their capability to increase independence with ADLs had a higher adjusted probability of successful discharge than patients with negative beliefs (positive, 63.8%; negative, 57.8%; difference, 6.0%, 95% confidence interval [CI], 5.4-6.6). This remained true regardless of staff beliefs, but the difference in successful discharge probability between patients with positive and negative beliefs was larger when staff had positive beliefs. Conversely, the association between staff beliefs and successful discharge varied based on patient beliefs. If patients had positive beliefs, the difference in the probability of successful discharge between positive and negative staff beliefs was 2.5% (95% CI, 1.0-4.0). If patients had negative beliefs, the difference between positive and negative staff beliefs was –4.6% (95% CI, –6.0 to –3.2).ConclusionsPatients’ beliefs have a significant association with the probability of successful discharge. Understanding patients’ beliefs is critical to appropriate goal-setting, discharge planning, and quality SNF care.     

Comparison Between Common Performance-Based Tests and Self-Reports of Physical Function in People With Multiple Sclerosis: Does Sex or Gender Matter?

ObjectiveTo estimate the extent to which sex or gender differences affect the relations between tests of physical performance and self-reports about function in everyday life activities. Ecological validity is an important psychometric property when choosing tests of physical function, because they need to relate to everyday function. In multiple sclerosis (MS), the EQUI scale, modified Canadian Aerobic Fitness Test, grip strength, vertical jump, push-up, partial curl-up, gait speed (comfortable or fast), 6-minute walk test, and 9-hole peg test are commonly used but the extent to which they relate to everyday function is understudied and the extent to which ecological validity of these tests differ between women and men is unknown.DesignA cross-sectional analysis was conducted on a random sample of men and women recruited for a study on the life effect of MS. Correlations between pairs of performance outcome (PerfO) and self-reported outcome (SRO) items pairs of variables with theoretical coherence were calculated and gender effects identified using linear regression.SettingParticipants were recruited from MS clinic at Montreal Neurological Hospital.ParticipantsThe sample (N=188) consisted of 140 women and 48 men with MS.InterventionsNot applicable.ResultsThe mean age ± SD of the participants was 43±10. Sixty PerfO and SRO items yielded 165 theoretically linked pairs separately for women and men. Of these 330 possible pairs, 77 pairs (23%) had correlations ≥0.8, showing strong support for the link between performance tests and everyday function; 203 pairs provided moderate support (r≥0.5). Thirty-one pairs had a statistically significant interaction with gender with men having higher correlations than women (n=27/31).ConclusionThe results support the ecological validity for physical performance tests, particularly balance tests and particularly for men. The observation that many indicators of everyday function derived from SROs were related to physical performance supports the routine use of SROs in clinical practice to guide therapy to meet the needs of clients with MS.     

National Institutes of Health Toolbox Emotion Battery: Application of Summary Scores to Adults With Spinal Cord Injury,Traumatic Brain Injury,and Stroke

ObjectiveTo examine the validity of factor analytically based summary scores that were developed using the National Institutes of Health Toolbox Emotion Battery (NIHTB-EB); (ie, psychological well-being, social satisfaction, negative affect) normative sample in individuals with neurologic conditions.DesignCross-sectional, observational cohort.SettingCommunity.ParticipantsA total of 1036 English-speaking adults from the National Institutes of Health Toolbox (NIHTB) normative project and 604 community-dwelling adults with neurologic conditions including spinal cord injury (SCI n=209), traumatic brain injury (TBI n=184), and stroke (cerebrovascular accident [CVA] n=211) (N=1640).InterventionNot applicable.Main Outcome MeasuresThe NIHTB-EB.ResultsA series of univariate analyses comparing summary scores across the 4 groups (SCI, TBI, CVA, normative group) were conducted to identify group differences. Base rates (defined as >1 SD toward the problematic direction) were also identified. The normative group demonstrated better emotional functioning characterized by greater social satisfaction and psychological well-being (normative group > SCI, TBI, CVA; P’s <.0001), and less negative affect (normative group < SCI, P=.016; normative group < TBI, P<.001; normative group < CVA; P=.034) compared with each neurologic group. Using base rates to identify problematic emotions for the 3 summary scores, there were higher rates of problematic emotions on all 3 summary scores for the neurologic groups compared with the normative group.ConclusionsThe NIHTB-EB summary scores demonstrate an increased prevalence of problematic emotions among individuals with 3 neurologic conditions, and might be useful for identifying individuals with similar conditions and potentially in need of psychological support.
