Objective
To document in adults affected by autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) the intra- and interrater reliability, standard error of measurement, agreement, minimal detectable change, and construct validity of the 9-Hole Peg Test (NHPT), the Standardized Finger-to-Nose Test (SFNT), and grip strength.Design
Metrologic study.Setting
Neuromuscular rehabilitation clinic.Participants
Genetically confirmed adult patients with ARSACS (N=42; 21 women; mean age, 38.6y).Interventions
Not applicable.Main Outcome Measures
Intra- and interrater reliability was determined using the intraclass correlation coefficient (ICC). Construct validity was determined by assessing the capacity of the NHPT, the SFNT, and grip strength to distinguish between participants based on sex, mobility stages, and age groups, and on performance on the Archimedes spiral and fast alternating hand movements tests.Results
All 3 tests have shown excellent reliability (ICC=.90–.98). However, the limit of agreement was influenced by the participant’s performance on the NHPT, and the minimal detectable change was very different for both hands (right=9.7 vs left=28.0). Construct validity was confirmed for the SFNT and NHPT, but it was not demonstrated for grip strength.Conclusions
Given the metrologic properties assessed in this study, the SFNT is an excellent measure to assess upper limb coordination, whereas the NHPT must be used with caution. The grip strength is reliable but does not seem to reflect disease severity. 相似文献2.
Background
A variety of tests have been proposed to measure the performance of neck flexor muscles, but head-to-head comparisons hardly have been documented.Objective
To compare reliability indexes, construct validity, and ability to discriminate between individuals with and without neck pain of 4 muscle tests (deep neck flexors endurance test [DNFET]; 2 variations of the craniocervical flexion test [CCFT1 and CCFT2]; and dynamometry).Design
Reliability and validity study.Setting
General community.Participants
A total of 66 participants, 33 with chronic idiopathic neck pain (mean ± standard deviation pain intensity: 3.2 ± 1.9) and 33 without neck pain, from the general population.Methods/Main Outcome
Neck muscle functioning was assessed with the CCFT1, the CCFT2, the DNFET, and dynamometry on 2 separate sessions. Participants with neck pain also were assessed for pain intensity, disability, pain catastrophizing, and fear of movement.Results
Relative reliability of all tests was at least moderate (intraclass correlation coefficient ≥ 0.62), whereas measurement error was high, particularly for the DNFET (95% minimum detectable change ≥ 23.00 seconds). All tests showed moderate correlation (r ≥ 0.3) with at least 2 pain-related measures and moderate-to-strong correlations with each other. Principal component analysis retained 2 factors explaining 68%-73% of the variance of the 4 muscle tests. Significant differences between groups were found for the DNFET and dynamometry (P < .05).Conclusion
The reliability indexes suggest that the DNFET and the CCFT may be more appropriate for group comparisons than for individual comparisons. The 4 tests seem to have construct validity, but they also seem to measure slightly different constructs.Level of Evidence

Context
Spirituality plays an important role in coping with chronic diseases for patients and they often report unmet spiritual and existential needs, which should be considered for a holistic view of their health. Studying spiritual needs in this generation requires culturally appropriate and valid instruments. The aim of this study was to determine the psychometric properties, such as validity, reliability, and factor structure of the Persian version of Spiritual Needs Questionnaire (SpNQ).Objectives
The aim of this study was to determine the psychometric properties, such as validity, reliability, and factor structure of the Persian version of Spiritual Needs Questionnaire (SpNQ).Methods
The “forward-backward” procedure was applied to translate the SpNQ from English into Persian. The SpNQ-Persian Version (SpNQ-PV) was checked in terms of validity and reliability with a convenience sample of 100 elders with chronic diseases who were recruited from the inpatient wards at two university hospitals in Qom, Iran. The validity was assessed using content, face, and construct validity. The Cronbach alpha and test-retest were used to assess the reliability of the questionnaire.Results
The results of the exploratory factor analysis indicated a five-factor solution for the questionnaire, which included religious needs, existential needs, forgiveness/generativity needs, need for inner peace, and emotional needs. These accounted for 60.1% of the total observed variance. One item was removed (factor loading <0.4). Convergent validity was supported mostly by the pattern of association between SpNQ-PV and the Spiritual Well-being Scale. Cronbach alpha of the subscales ranged from 0.56 to 0.78 and the test-retest reliability ranged from 0.72 to 0.91, which indicated an acceptable range of reliability.Conclusion
The SpNQ-PV showed a minor difference in structuring and indicated good psychometric properties, which can be used to assess the spiritual needs of Iranian elders suffering from chronic diseases. 相似文献4.

Context
The Memorial Symptom Assessment Scale (MSAS) is a self-rating instrument for the assessment of symptom distress in cancer patients. The Spanish version of the MSAS has recently been validated. However, we lack evidence of the internal construct validity of the shorter versions (short form [MSAS-SF] and condensed form [CMSAS]). In addition, rigorous testing of these scales with modern psychometric methods is needed.Objectives
The aim of this study was to evaluate the internal construct validity and reliability of the Spanish versions of the MSAS-SF and CMSAS in oncology outpatients using Rasch analysis.Methods
Data from a convenience sample of oncology outpatients receiving chemotherapy (n = 306; mean age 60 years; 63% women) at a university hospital were analyzed. The Rasch unidimensional measurement model was used to examine response category functioning, item hierarchy, targeting, unidimensionality, reliability, and differential item functioning by age, gender, and marital status.Results
The response category structure of the symptom distress items was improved by collapsing two categories. The scales were adequately targeted to the study patients, showed overall Rasch model fit (mean Infit MnSq ranged from 0.98 to 1.05), met criteria for unidimensionality, and the reliability of scores was good (person reliability > 0.80), except for the CMSAS prevalence scale. Only four items showed differential item functioning.Conclusion
The present study demonstrated that the Spanish versions of the MSAS-SF and CMSAS have adequate psychometric properties to evaluate symptom distress in oncology outpatients. Additional studies of the CMSAS are recommended. 相似文献5.
Is Going Beyond Rasch Analysis Necessary to Assess the Construct Validity of a Motor Function Scale?

Objective
To examine whether a Rasch analysis is sufficient to establish the construct validity of the Motor Function Measure (MFM) and discuss whether weighting the MFM item scores would improve the MFM construct validity.Design
Observational cross-sectional multicenter study.Setting
Twenty-three physical medicine departments, neurology departments, or reference centers for neuromuscular diseases.Participants
Patients (N=911) aged 6 to 60 years with Charcot-Marie-Tooth disease (CMT), facioscapulohumeral dystrophy (FSHD), or myotonic dystrophy type 1 (DM1).Interventions
None.Main Outcome Measure(s)
Comparison of the goodness-of-fit of the confirmatory factor analysis (CFA) model vs that of a modified multidimensional Rasch model on MFM item scores in each considered disease.Results
The CFA model showed good fit to the data and significantly better goodness of fit than the modified multidimensional Rasch model regardless of the disease (P<.001). Statistically significant differences in item standardized factor loadings were found between DM1, CMT, and FSHD in only 6 of 32 items (items 6, 27, 2, 7, 9 and 17).Conclusions
For multidimensional scales designed to measure patient abilities in various diseases, a Rasch analysis might not be the most convenient, whereas a CFA is able to establish the scale construct validity and provide weights to adapt the item scores to a specific disease. 相似文献6.

Objective
To assess consensual validity, interrater reliability, and criterion validity of the International Dysphagia Diet Standardisation Initiative Functional Diet Scale, a new functional outcome scale intended to capture the severity of oropharyngeal dysphagia, as represented by the degree of diet texture restriction recommended for the patient.Design
Participants assigned International Dysphagia Diet Standardisation Initiative Functional Diet Scale scores to 16 clinical cases. Consensual validity was measured against reference scores determined by an author reference panel. Interrater reliability was measured overall and across quartile subsets of the dataset. Criterion validity was evaluated versus Functional Oral Intake Scale (FOIS) scores assigned by survey respondents to the same case scenarios. Feedback was requested regarding ease and likelihood of use.Setting
Web-based survey.Participants
Respondents (N=170) from 29 countries.Interventions
Not applicable.Main Outcome Measures
Consensual validity (percent agreement and Kendall τ), criterion validity (Spearman rank correlation), and interrater reliability (Kendall concordance and intraclass coefficients).Results
The International Dysphagia Diet Standardisation Initiative Functional Diet Scale showed strong consensual validity, criterion validity, and interrater reliability. Scenarios involving liquid-only diets, transition from nonoral feeding, or trial diet advances in therapy showed the poorest consensus, indicating a need for clear instructions on how to score these situations. The International Dysphagia Diet Standardisation Initiative Functional Diet Scale showed greater sensitivity than the FOIS to specific changes in diet. Most (>70%) respondents indicated enthusiasm for implementing the International Dysphagia Diet Standardisation Initiative Functional Diet Scale.Conclusions
This initial validation study suggests that the International Dysphagia Diet Standardisation Initiative Functional Diet Scale has strong consensual and criterion validity and can be used reliably by clinicians to capture diet texture restriction and progression in people with dysphagia. 相似文献7.

Objective
To evaluate the content, construct, and discriminant validity of the Narrowing Beam Walking Test (NBWT), a performance-based balance test for lower limb prosthesis users.Design
Cross-sectional study.Setting
Research laboratory and prosthetics clinic.Participants
Unilateral transtibial and transfemoral prosthesis users (N=40).Interventions
Not applicable.Main Outcome Measures
Content validity was examined by quantifying the percentage of participants receiving maximum or minimum scores (ie, ceiling and floor effects). Convergent construct validity was examined using correlations between participants’ NBWT scores and scores or times on existing clinical balance tests regularly administered to lower limb prosthesis users. Known-groups construct validity was examined by comparing NBWT scores between groups of participants with different fall histories, amputation levels, amputation etiologies, and functional levels. Discriminant validity was evaluated by analyzing the area under each test’s receiver operating characteristic (ROC) curve.Results
No minimum or maximum scores were recorded on the NBWT. NBWT scores demonstrated strong correlations (ρ=.70?.85) with scores/times on performance-based balance tests (timed Up and Go test, Four Square Step Test, and Berg Balance Scale) and a moderate correlation (ρ=.49) with the self-report Activities-specific Balance Confidence scale. NBWT performance was significantly lower among participants with a history of falls (P=.003), transfemoral amputation (P=.011), and a lower mobility level (P<.001). The NBWT also had the largest area under the ROC curve (.81) and was the only test to exhibit an area that was statistically significantly >.50 (ie, chance).Conclusions
The results provide strong evidence of content, construct, and discriminant validity for the NBWT as a performance-based test of balance ability. The evidence supports its use to assess balance impairments and fall risk in unilateral transtibial and transfemoral prosthesis users. 相似文献8.

Online version of the Ohio State University Traumatic Brain Injury Identification Method, Rivermead Postconcussion Symptoms Questionnaire (RPQ), Patient-Reported Outcomes Measurement Information System Cognitive Concerns Scale.Results
The measure was completed by 89.4% of the sample with most participants completing the measure in <8 minutes. After controlling for age, sex, psychiatric history, drug or alcohol history, and history of developmental disability, worst TBI severity was significantly associated with scores on the RPQ, F(2,230)=4.56, P=.011, and having a TBI within the past 2 years was associated with higher scores on the cognitive factor subscale of the RPQ, F(1,75)=7.7, P=.007.Conclusions
The online administration of the Ohio State University Traumatic Brain Injury Identification Method appears to be feasible in the general population. Preliminary validity was demonstrated for the indices of worst TBI severity and time since most recent TBI. 相似文献9.

Objective
To systematically synthesize and appraise research regarding test-retest reliability or criterion validity of subjective measures for assessing aerobic exercise intensity in adults with spinal cord injury (SCI).Data Sources
Electronic databases (Pubmed, PsychINFO, SPORTDiscus, EMBASE, and CINAHL) were searched from inception to January 1, 2016.Study Selection
Studies involving at least 50% of participants with SCI who performed an aerobic exercise test that included measurement of subjective and objective intensity based on test-retest reliability or criterion validity protocols.Data Extraction
Characteristics were extracted on study design, measures, participants, protocols, and results. Each study was evaluated for risk of bias based on strength of the study design and a quality checklist score (COnsensus-based Standards for the selection of health Measurement INstruments [COSMIN]).Data Synthesis
The 7 eligible studies (1 for reliability, 6 for validity) evaluated overall, peripheral and/or central ratings of perceived exertion (RPE) on a scale of 6-20 (RPE 6-20). No eligible studies were identified for other subjective intensity measures. The evidence for reliability and validity were synthesized separately for each measure and were assessed using Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Overall, very low GRADE confidence ratings were established for reliability and validity evidence generalizable to the entire population with SCI and various upper-body and lower-body modalities. There was low confidence for the evidence showing that overall RPE 6-20 has acceptable validity for adults with SCI and high fitness levels performing moderate to vigorous-intensity upper-body aerobic exercise.Conclusions
Health care professionals and scientists need to be aware of the very low to low confidence in the evidence, which currently prohibits a strong clinical recommendation for the use of subjective measures for assessing aerobic exercise intensity in adults with SCI. However, a tentative, conditional recommendation regarding overall RPE 6-20 seems applicable, depending on participants’ fitness level as well as the exercise intensity and modality used.Level of Evidence

59-Item WheelCon-P.Results
Principal component analyses confirmed the presence of 2 self-efficacy dimensions: mobility and social situation. Eleven mobility items and 5 social situation items fit the Rasch rating scale model. Three items misfit the model using all 16 items (ie, WheelCon-P short form). In each of the mobility, social situation, and WheelCon-P short form range of measurements, the 2 lowest and 2 highest measures had internal consistency reliability estimates below .70; all other measures had reliability estimates above .70.Conclusions
The WheelCon-P is composed of 2 self-efficacy dimensions related to mobility and social situations. The scores from the WheelCon-P short form and the 11-item mobility and 5-item social situation dimensions using a 0 to 10 response scale have good reliability. 相似文献11.

Objective
To evaluate the internal consistency and test-retest reliability, construct validity, and feasibility of the WatLX, a measure of the experience of patients in rehabilitative care.Design
Multisite, cross-sectional, and test-retest self-report study.Setting
Outpatient rehabilitative care settings.Participants
The WatLX was administered to English-speaking, cognitively intact outpatients (N=1174) over 18 years old who had completed a program of cardiac, musculoskeletal, neurologic, stroke, pulmonary, or speech language rehabilitative care, at 2 separate time points: (1) immediately following completion of their rehabilitation program, and (2) 2 weeks later (n=29). A subsequent feasibility study was conducted with 1013 patients from 19 clinics.Interventions
Not applicable.Main Outcome Measures
The WatLX measures 6 concepts, previously identified as key to outpatient rehabilitative care patients’ experience: (1) ecosystem issues, (2) client and informal caregiver engagement, (3) patient and health care provider relations, (4) pain and functional status, (5) group and individual identity, and (6) open-ended feedback.Results
Reliability analyses were conducted on 2 versions of the WatLX. Using a 7-point versus a 5-point Likert scale resulted in higher internal consistency and reliability scores. Cronbach’s alpha coefficients were .863 and .957 for the 5- and 7-point scale, respectively, and the ICC scores were .827 and .880, respectively. The proof of concept study recruited 1013 patients with little interruption of workflow; results displayed strong internal consistency (Cronbach’s alpha coefficient =.906). There is evidence of ceiling effects.Conclusions
The WatLX is a parsimonious question set that is feasible for administration in ambulatory rehabilitative care settings, and which shows promising psychometric properties. 相似文献12.

Purpose
The prevalence of dementia has increased rapidly with an aging Korean population. Compared to those without dementia, individuals with dementia have more and complex needs. In this study, the Korean version of the Camberwell Assessment of Need for the Elderly (CANE-K) was evaluated to determine its suitability for individuals with dementia in Korea.Methods
The CANE-K was developed following linguistic validation. The reliability of the measurement was examined with Cronbach α coefficient. The factor structure and construct validity were evaluated by performing exploratory factor analysis and confirmatory factor analyses. Pearson's correlation coefficients with related measures were used to ensure concurrent validity.Results
Four factors extracted with exploratory factor analysis and confirmatory factor analyses validated the model structure (χ2 = 367.25, p < .001, goodness-of-fit index = .84, adjusted goodness-of-fit index = .80, root mean square error of approximation = .07, and comparative fit index = .83). Items on the CANE-K loaded on the four factors in a range between .40 and .80. The output of Pearson's correlation coefficient with cognitive impairment, behavioral problems, activities of daily living, and caregiver burden showed acceptable concurrent validity.Conclusion
The CANE-K showed a reasonable degree of reliability and validity. Therefore, it has good potential to appropriately measure the needs and unmet needs of those with dementia. 相似文献13.

Not applicable.Main Outcomes Measures
The Mobility Device Impact Scale, Patient-Reported Outcomes Measurement Information System Social Function (version 2.0) scale, including Ability to Participate in Social Roles and Activities and Satisfaction with Social Roles and Activities, and the 2 Community Participation Indicators' enfranchisement scales. Details about device quality (reparability, reliability, ease of maintenance) and device type were also collected.Results
Respondents used ambulation aids (30%), manual (34%), and power wheelchairs (30%). Indicators of device quality had a moderating effect on participation outcomes, with 3 device quality variables (repairability, ease of maintenance, device reliability) accounting for 20% of the variance in participation. Wheelchair users reported lower participation enfranchisement than did ambulation aid users.Conclusions
Mobility device quality plays an important role in participation outcomes. It is critical that people have access to mobility devices and that these devices be reliable. 相似文献14.

Objective
To investigate interrater and intrarater reliability, measurement error, and convergent and discriminative validity of the Adult Assisting Hand Assessment Stroke (Ad-AHA Stroke).Design
Cross-sectional observational study.Setting
A total of 7 stroke rehabilitation centers.Participants
Stroke survivors (reliability sample: n=30; validity sample: N=118) were included (median age 67y; interquartile range [IQR], 59-76); median time poststroke 81 days (IQR 57-117).Interventions
N/A.Main Outcome Measures
Ad-AHA Stroke, Action Research Arm Test (ARAT), upper extremity Fugl-Meyer Assessment (UE-FMA). The Ad-AHA Stroke is an observation-based instrument assessing the effectiveness of the spontaneous use of the affected hand when performing bimanual activities in adults poststroke. Reliability of Ad-AHA Stroke was examined using intraclass correlation coefficients (ICCs), Bland–Altman plots, and weighted kappa statistics for reliability on item level. SEM was calculated based on Ad-AHA units. Convergent validity was assessed by calculating Spearman rank correlation coefficients between Ad-AHA Stroke and ARA test and UE-FMA. Comparison of Ad-AHA Stroke scores between subgroups of patients according to hand dominance, neglect, and age evaluated discriminative validity.Results
Intrarater and interrater agreement showed an ICC of 0.99 (95% confidence interval, 0.99-0.99), an SEM of 2.15 and 1.64 out of 100, respectively, and weighted kappa for item scores were all above 0.79. The relation between Ad-AHA and other clinical assessments was strong (ρ=0.9). Patients with neglect had significantly lower Ad-AHA scores compared to patients without neglect (P=.004).Conclusions
The Ad-AHA Stroke captures actual bimanual performance. Therefore, it provides an additional aspect of upper limb assessment with good to excellent reliability and low SEM for patients with subacute stroke. High convergent validity with the ARA test and UE-FMA and discriminative validity were supported. 相似文献15.

Objectives
To critically appraise the measurement property evidence (ie, psychometric) for 8 observation-based financial management assessment instruments.Data sources
Seven databases were searched in May 2015.Study selection
Two reviewers used an independent decision-agreement process to select studies of measurement property evidence relevant to populations with adulthood acquired cognitive impairment, appraise the quality of the evidence, and extract data. Twenty-one articles were selected.Data extraction
This review used the COnsensus-based Standards for the selection of health Measurement Instruments review guidelines and 4-point tool to appraise evidence. After appraising the methodologic quality, the adequacy of results and volume of evidence per instrument were synthesized. Measurement property evidence with high risk of bias was excluded from the synthesis.Data synthesis
The volume of measurement property evidence per instrument is low; most instruments had 1 to 3 included studies. Many included studies had poor methodologic quality per measurement property evidence area examined. Six of the 8 instruments reviewed had supporting construct validity/hypothesis-testing evidence of fair methodologic quality. There is a dearth of acceptable quality content validity, reliability, and responsiveness evidence for all 8 instruments.Conclusions
Rehabilitation practitioners assess financial management functions in adults with acquired cognitive impairments. However, there is limited published evidence to support using any of the reviewed instruments. Practitioners should exercise caution when interpreting the results of these instruments. This review highlights the importance of appraising the quality of measurement property evidence before examining the adequacy of the results and synthesizing the evidence. 相似文献16.

To evaluate reproducibility (reliability and agreement) of the Brachial Assessment Tool (BrAT), a new patient-reported outcome measure for adults with traumatic brachial plexus injury (BPI).Design
Prospective repeated-measure design.Setting
Outpatient clinics.Participants
Adults with confirmed traumatic BPI (N=43; age range, 19–82y).Interventions
People with BPI completed the 31-item 4-response BrAT twice, 2 weeks apart. Results for the 3 subscales and summed score were compared at time 1 and time 2 to determine reliability, including systematic differences using paired t tests, test retest using intraclass correlation coefficient model 1,1 (ICC1,1), and internal consistency using Cronbach α. Agreement parameters included standard error of measurement, minimal detectable change, and limits of agreement.Main Outcome Measure
BrAT.Results
Test-retest reliability was excellent (ICC1,1=.90–.97). Internal consistency was high (Cronbach α=.90–.98). Measurement error was relatively low (standard error of measurement range, 3.1–8.8). A change of >4 for subscale 1, >6 for subscale 2, >4 for subscale 3, and >10 for the summed score is indicative of change over and above measurement error. Limits of agreement ranged from ±4.4 (subscale 3) to 11.61 (summed score).Conclusions
These findings support the use of the BrAT as a reproducible patient-reported outcome measure for adults with traumatic BPI with evidence of appropriate reliability and agreement for both individual and group comparisons. Further psychometric testing is required to establish the construct validity and responsiveness of the BrAT. 相似文献17.

Objectives
To evaluate construct validity and responsiveness of the Brachial Assessment Tool (BrAT), a new patient-reported outcome measure for people with traumatic brachial plexus injury (BPI), and to compare it to the Disabilities of the Arm, Shoulder and Hand (DASH) and the Upper Extremity Functional Index (UEFI).Design
Cross-sectional study.Setting
Outpatient clinics.Participants
Adults (N=29; age range, 20–69y) with confirmed traumatic BPI.Interventions
Participants completed the BrAT 3 times over an 18-month period together with 16 DASH activity items and the UEFI. Evaluations were undertaken of construct validity, known-groups validity, 1-way repeated analysis of variance, and effect size.Main Outcome Measures
BrAT, DASH, and UEFI.Results
The BrAT demonstrated a moderate to low correlation with the DASH activity items (<0.7) and a large correlation with the UEFI (>0.7). According to known-groups validity, only the BrAT was able to discriminate between people who stated they could use their hand versus those who were unable to use their hand to perform activities. All measures indicated a significant effect for time with the exception of BrAT subscale 1. The effect size was highest for the BrAT but lower than expected (BrAT, .52–.40; DASH, .15; UEFI, .36).Conclusions
These preliminary findings support the BrAT as a valid and responsive patient-reported outcome measure for adults with traumatic BPI. The BrAT activity items appear to be more targeted than the DASH or UEFI particularly for people with more severe BPI. The BrAT also appears to be measuring a different activity construct than the DASH and the UEFI. Further work is required to confirm these results with larger sample sizes. 相似文献18.

Objectives
(1) To develop a performance-based measure for adult upper limb (UL) prosthetic functioning through broad (ie, overall performance) and functional domain-specific (eg, control skills) assessment of commonplace activities; (2) to conduct initial psychometric evaluation of the Capacity Assessment of Prosthetic Performance for the Upper Limb (CAPPFUL).Design
Internal consistency of CAPPFUL and interrater reliability for task, functional domain, and full-scale (sub)scores among 3 independent raters were estimated. Known-group validity was examined comparing scores by amputation level. Convergent validity was assessed between CAPPFUL and 2 hand dexterity or function tests; discriminant validity was assessed against self-reported disability.Setting

Not applicable.Results
Interrater reliability was excellent for scoring on the task, domain, and full-scale scores (intraclass correlation coefficients=.88-.99). Internal consistency was good (α=.79-.82). Generally, subjects with higher UL amputation levels scored lower (worse) than subjects with lower UL amputation levels. CAPPFUL demonstrated strong correlations with measures of hand dexterity or functioning (rs=?.58 to .72) and moderate correlation with self-reported disability (r=?.35).Conclusions
CAPPFUL was designed as a versatile, low-burden measure of prosthesis performance for any UL functional prosthetic device type and any UL amputation level. CAPPFUL assesses overall performance and 5 functional performance domains during completion of 11 tasks that require movement in all planes while manipulating everyday objects requiring multiple grasp patterns. Psychometric evaluation indicates good interrater reliability, internal consistency, known-group validity, and convergent and discriminant validity. 相似文献19.

Patients completed the PWPE and the WD-FAB physical function scales including Changing and Maintaining Body Position, Whole Body Mobility, Upper Body Function, and Upper Extremity Fine Motor. The physical therapist also answered the WD-FAB questions on the patient’s physical functioning. The WD-FAB computer-adaptive test version administered up to 10 items for each scale. The PWPE produces ratings from 0 to 5 indicating overall Level of Work ability: 0 (unable to work); 1 (sedentary); 2 (light); 3 (medium); 4 (heavy); 5 (very heavy). The PWPE also produces Level of Work ability ratings in the Dynamic Strength, Position Tolerance, and Mobility subsections.Results
Participating in the study were 50 patients with 1 or more conditions (shoulder, n=21; knee, n=16; low back, n=13; ankle/foot, n=10; neck, n=8; hip, n=7). The patient-based WD-FAB scores demonstrated moderate, statistically significant correlations with the provider proxy WD-FAB report (R=.49-.65). The WD-FAB Upper Body Function scale scores demonstrated moderate strength relationships with the PWPE overall ratings. The Whole Body Mobility and Changing and Maintaining Body Position scales did not demonstrate statistically significant relationships with the PWPE overall ratings.Conclusions
We found moderate evidence for validity for the WD-FAB Upper Body Function, Whole Body Mobility, and Changing and Maintaining Body Position scales relative to clinician report and varied evidence relative to the PWPE in this clinical sample. 相似文献20.
