Validation of Persian Version of Patient-Rated Wrist and Hand Evaluation: Confirmatory Factor Analysis and Rasch Analysis

Measurement properties of the Dutch versions of QuickDASH and PRWHE in patients with complaints of hand, wrist, forearm and elbow

BACKGROUND

The shortened version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) and Patient Rated Wrist/Hand Evaluation (PRWHE) are commonly used questionnaires to assess patient-reported hand function. Information about the measurement properties of the Dutch versions is scarce.

OBJECTIVE

To gain insight into the measurement properties of the Dutch language versions of the QuickDASH and the PRWHE in patients with (non)specific complaints of the hand, wrist, forearm and elbow.

METHODS

Internal consistency, construct validity, test-retest reliability, responsiveness, and floor and ceiling effects were assessed according to COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) recommendations.

RESULTS

Questionnaires were filled out by 132 patients. Internal consistency of QuickDASH (Cronbach's α= 0.92) and PRWHE (Cronbach's α= 0.97) was high. Predefined hypotheses for construct validity were not confirmed for 75% for both QuickDASH and PRWHE (accordance with 62% of predefined hypotheses for both questionnaires). Test-retest reliability of QuickDASH (ICC = 0.90) and PRWHE (ICC = 0.87) was good. Both QuickDASH (AUC = 0.84) and PRWHE (AUC = 0.80) showed good responsiveness. No floor or ceiling effects were present.

CONCLUSIONS

Measurement properties of the Dutch language versions of the QuickDASH and the PRWHE, applied to patients with (non)specific complaints of the hand, wrist, forearm and elbow, were very similar. Test-retest reliability and responsiveness were good for both QuickDASH and PRWHE. Construct validity could not be demonstrated sufficiently.

Occupational Performance 1 Year After a Distal Radius Fracture From the Perspective of the International Classification of Functioning, Disability and Health

IMPORTANCE

Distal radius fractures (DRFs) frequently compromise independent functioning.

OBJECTIVE

To analyze occupational performance post-DRF using the Canadian Occupational Performance Measure (COPM) and related interviews, guided by the International Classification of Functioning, Disability and Health (ICF). COPM score was compared with standard metrics: Patient-Reported Wrist Evaluation (PRWE) and Participation Behavior Questionnaire (PBQ).

METHOD

Through a semistructured COPM interview, participants highlighted self-care, productivity, and leisure. They completed the PRWE and PBQ, linking results to ICF sets.

DESIGN

Prospective cohort.

SETTING

Outpatient hand surgery clinic at a trauma center.

PARTICIPANTS

Patients (N = 120), 1 yr post-DRF.

OUTCOMES AND MEASURES

Incorporated COPM, PRWE, and PBQ, linked to ICF.

RESULTS

Analysis identified 73 codes, aligning with 30 ICF Hand Conditions codes. Main concerns related to self-care (15.21%), leisure (12.16%), and productivity (16.22%). Major challenges pertained to domestic (67.00%) and civic life (64.53%) within ICF. Occupational performance was positively correlated with participation (r = .62) and inversely with disability (r = -.62).

CONCLUSIONS AND RELEVANCE

DRFs result in varied occupational challenges that are not always reflected in standard measures. The COPM offers a comprehensive insight into post-DRF patient challenges, emphasizing the value of diverse clinical assessment approaches. What This Article Adds: This study highlights the importance of a holistic approach in occupational therapy for DRF patients, revealing that standard measurements might overlook key challenges that they face. By adopting broader evaluative methods, occupational therapists can better address patient-specific needs and enhance their rehabilitation outcomes.

Factor structure of Participation Behavioural Questionnaire (PBQ) in patients with hand injuries

BACKGROUND

Participation is considered a critical outcome of successful rehabilitation and should be evaluated.

OBJECTIVE

We aimed to evaluate the structural validity of the Participation Behaviour Questionnaire (PBQ) in people with hand injuries.

METHODOLOGY

The PBQ contains 30 items that measure participation as conceptualized in the ICF. PBQ was developed with Rasch analysis to measure participation in hand injured. A sample of 404 patients with hand injuries and a mean age of 37 (16.0) participated and was randomly split for exploratory and confirmatory factor analysis (EFA/CFA).

RESULTS

Both EFA and CFA confirmed a four factor-solution. These factors were named: Social Participation and Interpersonal Relationships, Autonomy and Role, Subjective Satisfaction with Participation, Recreational, Sport, and Leisure Time. The value of Cronbach's alpha was 0.96 for the total scale and >0.85 for each subscale.

CONCLUSIONS

The structural validity of the PBQ was confirmed using both EFA and CFA. The PBQ measures four dimensions of participation.

A systematic review and meta-analysis of Patient-Rated Wrist (and Hand) Evaluation (PRWE/PRWHE) measurement properties, translation, and/ or cross-cultural adaptation

PURPOSE

To critically appraise, summarize, and synthesize the evidence on the psychometric, translation and/or cross-cultural adaptation properties of the Patient-Rated Wrist (and Hand) Evaluation (PRWE/PRWHE).

MATERIALS AND METHODS

Four electronic databases were searched from 1998 to February 2021. Studies addressing psychometric, translation and/or cross-cultural adaptation properties were included. Two independent reviewers extracted data and assessed methodological quality of the studies using the COSMIN checklist. Where possible, meta-analysis was conducted to pool the estimates of each measurement property. Otherwise, qualitative synthesis was conducted. The overall quality of evidence on each measurement property was provided using GRADE principles.

RESULTS

Forty-four studies were eligible for data extraction. The PRWE/PRWHE has been translated into 21 languages. The best factor structure was a one-dimensional construct with three unidimensional subscales. High-quality evidence supports very good structural and cross-cultural validity, internal consistency, test-retest reliability, measurement error, and hypothesis testing for construct validity against DASH in wrist and hand injuries. However, low-quality evidence supports acceptable responsiveness property. The minimal clinically important difference for the PRWE/PRWHE was 24 points for patient-level comparisons and 17 for groups.

CONCLUSION

High-quality evidence supports the use of PRWE/PRWHE as a reliable, valid, and structurally sound questionnaire to assess pain and disability in patients with various wrist and hand injuries. Registration code: CRD42020180250IMPLICATION FOR REHABILITATIONSThe PRWE/PRWHE is a reliable and valid anatomical region-specific measure to assess pain and disability in patients with wrist and hand injuries.Each individual subscale of the PRWE/PRHWE (pain, specific activities, and usual activities) can be used separately as a measure of pain and disability.Change scores less than 9/100 in the total score, should be considered as measurement error, not ‎real change. Changes in the total score between 17 and 24/100 could be assumed as the minimal ‎clinically important change in the condition of patients over time. ‎The PRWE/PRWHE is available in 21 different languages and has been successfully adapted into highly diverse cultures. This point could be considered as one of the merits of using PRWE/PRWHE in clinical settings in multi-lingual and multi-cultural countries, when clinicians need a psychometrically sound ‎patient reported wrist/hand measure.‎.

Measurement properties of the Michigan hand outcomes questionnaire: Rasch analysis of responses from a traumatic hand injury population

PURPOSE

This study aimed to use Rasch analysis to test the content, scoring, and measurement properties of the Michigan Hand Outcomes Questionnaire (MHQ).

METHODS

MHQ scores from 196 patients with hand and wrist conditions were collected in an outpatient hand rehabilitation facility. Rasch analysis was conducted to assess the fit statistics of MHQ to confirm the scaling structure of disability subscales, and to identify differential item functioning.

RESULTS

The MHQ did not fit with the Rasch model (χ² = 2376.78, df = 74, p < 0.001), and most thresholds of item responses were disordered. The original scoring algorithm derived from 5-point Likert response options was adjusted to 3-point Likert (10 items) and 4-point Likert (11 items) based on the visual inspection of the thresholds map. Differential item functioning was present in the revised scale based on the age, sex, and dominant hand. Only 3 revised subscales of the MHQ including activities daily living (one hand), aesthetics, and satisfaction showed acceptable fit to the Rasch model. Unidimensionality was achieved in all revised subscales.

CONCLUSIONS

The overall MHQ had a substantial misfit from the Rasch model. Despite efforts of item reduction and rescoring, we did not reach a satisfactory solution. This calls into question the validity of the statistical evaluations performed on this scale using the traditional scoring.Implications for rehabilitationThe MHQ was designed to measure different dimensions of pain and disability but demonstrates multiple measurement problems that undermine it use in present form.It is not appropriate to sum all 37 items of the MHQ into a single score.Three subscales of activities daily living (one hand), aesthetics, and satisfaction can provide unidimensional subscales scores with interval level scaling if scored with our proposed Rasch-based revised scoring.The 27-item version of the MHQ is shown to have strong psychometric properties for administration with patients with hand injuries; however, it requires further validation.
