Validation of the Greek version of the device subscale of the Quebec User Evaluation of Satisfaction with Assistive Technology 2.0 (QUEST 2.0)

A systematic review of the psychometric properties of Quebec user evaluation of satisfaction with assistive technology (QUEST)

PURPOSE

The aim of this systematic review was to evaluate the psychometric properties of the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST).

MATERIALS AND METHODS

Searches were conducted in August 2021 on four electronic databases: MEDLINE, CINAHL, Scopus, and Web of Science. Eligible papers included cross-sectional validation studies evaluating the psychometric properties of all QUEST versions. Cronbach's alpha, intraclass correlation coefficient, and comparison tools were reported. Study quality and risk of bias were assessed using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist.

RESULTS

Nineteen studies were included in this systematic review. Results showed that the QUEST and QUEST 2.0 were available in 10 languages, and most validation studies analysed this tool in patients using mobility devices in various clinical conditions. One article analysed the child version (QUEST 2.1) in English. The most analysed psychometric property was Cronbach's alpha for internal consistency in 14 out of 19 studies, with values ranging between 0.74 and 0.79. Overall, 17 out of 19 studies were of adequate quality, though responsiveness was never studied.

CONCLUSION

Our systematic review showed that the QUEST and its subsequent versions are reliable and valid measurement instruments to evaluate satisfaction in patients with different disabilities using various assistive technologies. This study provides useful information on the instrument's psychometric properties in different populations and cultures.

Iranian translation and psychometric of the Quebec user evaluation of satisfaction with Assistive technology (QUEST2.0) on wheelchair users

PURPOSE

QUEST2.0 is a practical tool specifically applied to assessing the satisfaction for awide array of assistive technology in a standard manner. Therefore, this study set to translate and evaluate the validity and reliability of the Iranian version of the QUEST2.0in Persian-speaking users of manual and electronic wheelchairs in Iran.

METHODS

The present study recruited 130 users of manual and electric wheelchairs. Psychometric properties, including; content validity and construct validity and internal consistency and test-retest reliability, were testified.

RESULTS

The content validity index of the questionnaire was 92%. The internal consistency was determined to be 0.89,0.88 and 0.74, respectively, for the whole questionnaire and dimensions of the device, and services. The test-retest reliability was 0.85, 0.80, and 0.94, respectively, for the whole questionnaire and dimensions of the device and services. Factor analysis confirmed the two-factor structure of the questionnaire. In the two-factor model, 57.75% of the total variance was explained by these two factors, of which 45.8% pertained to the first factor (device) and 11.95% to the second factor (service).

CONCLUSIONS

The results showed that QUEST2.0 had both valid and reliable for measuring satisfaction with assistive technology among wheelchair users. The assessment will also help facilitate the quality improvement processes in using assistive technology devices.

Psychometric evaluation of the Arabic version of the Quebec user evaluation of satisfaction with assistive technology (A-QUEST 2.0) in prosthesis users

BACKGROUND

The evaluation of patient satisfaction and perceptions plays a vital role in determining the quality of prosthesis users' devices and the competency of healthcare services.

AIM

To evaluate the psychometric properties of the Arabic Quebec User Evaluation of Satisfaction with Assistive Technology (A-QUEST 2.0) with prosthetics users.

DESIGN

A methodological study.

SETTING

Saudi Arabia, Turkey.

POPULATION

A convenience sample of outpatient prosthesis users (N.=183).

METHODS

The A-QUEST 2.0 includes two subscales respectively evaluating the user's satisfaction with the device and the services provided. The data for each subscale were investigated using Rasch analysis to evaluate the item fit, reliability indices, item difficulty, local item dependency, and differential item functioning (DIF).

RESULTS

Both subscales met the Rasch criteria for the functioning of rating scale categories. All items showed an acceptable fit to the Rasch model. The person separation indices for the Device and Services subscales were 2.21 (Cronbach's α=0.90) and 1.72 (Cronbach's α=0.85), respectively. Therefore, the two subscales are sensitive enough to distinguish between at least three different levels of satisfaction. The unidimensionality of each subscale was confirmed, and none of the items displayed differential item functioning across age, gender, location of amputation, country, and duration of use.

CONCLUSIONS

Overall, the findings indicate the psychometric evaluation of A-QUEST 2.0 is effective with prosthesis users across different clinical contexts and cultures. Thus, the A-QUEST 2.0 allows for a comprehensive understanding of users' perceptions of prosthesis characteristics, particularly among subjects with lower limb amputations caused by traumatic injuries.

CLINICAL REHABILITATION IMPACT

Our paper provides clinicians dealing with Arabic patients a validated outcome measure for satisfaction with prosthesis. Besides providing information in the development of new products and service delivery. Further studies are necessary to improve the measure's metric quality in different contexts and for different prosthesis devices.

Athletes with disability' satisfaction with sport wheelchairs: an Italian cross sectional study

PURPOSE

Physical activity is essential for health and well-being. People with physical disability often experience barriers in performing sports due to the lack of appropriate assistive technologies. The present research aimed to investigate athletes with disability satisfaction when using sports wheelchairs and to explore clinometric properties of the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST).

MATERIALS AND METHODS

One hundred and twenty-eight athletes were involved in the present study. Data on sport discipline and wheelchair provision were collected with qualitative approach. Internal consistency and reliability of QUEST were respectively analyzed with Cronbach's Alpha and Intraclass Correlation Coefficient. Validity was investigated with the correlation of the Wheelchair Use Confidence Scale for Manual users.

RESULTS

Results revealed good internal consistency (.858) and moderate inter-rater reliability for service subscale (.664) and for the total score (.675), while for device subscale (.802) reliability was high. Validity revealed moderate correlation (.300) with a p < 0.05. Qualitative analysis highlighted economic barriers as primary social determinant who affect participation in sport activities.

CONCLUSIONS

The present study confirms preliminary evidence of the QUEST for athletes with disability. The research group also recommends an international effort to promote a comprehensive evaluation of sports wheelchair involving rehabilitation professionals, sport technicians and people with disability.Implications for rehabilitationEconomic factors linked to the purchase of a wheelchair seem being the main barrier for practising sportThe Quebec User Evaluation of Satisfaction with Assistive Technology is a useful tool to measure athletes' satisfaction using a wheelchairRehabilitation professionals and sport technicians should collaborate together with people with disability in determining how choose appropriate sport wheelchairs.

Evaluation of satisfaction with geospatial assistive technology (ESGAT): a methodological and usability study

Purpose: Manual wheelchair users are more vulnerable, in situations such as road crossings, hazardous sidewalks or curbs and crossing of buildings and facilities threshold. Geospatial assistive technology (GAT) can help with route planning. However, it is important to ensure the usability of such products, as well as the satisfaction of persons with reduced mobility. The study's aim was (1) to develop and validate a questionnaire on the satisfaction of GAT, in English and French, and to (2) assess satisfaction, efficacy and efficiency of a GAT with manual wheelchair users following a filmed trial in a dense urban area.Method: A methodological study was conducted (development of the questionnaire, assessment of its content validity, feasibility and practicability) followed by a trial and post-observations with the videos. Two questionnaires (English, French) were concurrently validated by two groups of experts (n = 8), and then field-tested by wheelchair users (n = 8), using Google Maps Pedestrian routeing tool.Results: The Evaluation of satisfaction with geospatial assistive technology (ESGAT) consists in a user profile and their experience with the technology, followed by 12 satisfaction criteria rated from 1-not satisfied to 5-very satisfied. Both questionnaires were rated as feasible and practicable to complete. The usability of Google Maps Pedestrian routeing tool was measured as "moderate" by manual wheelchairs since the total satisfaction score at the ESGAT was 3.9/5 (quite satisfied). The items with the lowest score were navigation assistance, hands-free function and security. The GAT was effective (87.5% have completed their destination) but not efficient (37.5% needed help).IMPLICATIONS FOR REHABILITATIONFor manual wheelchair users paired with geospatial assistive technology:• A 10 minutes questionnaire was developed and validated to assess their satisfaction after testing aid in an urban area.• Satisfaction criteria to address are ease of access (service), learnability, hands-free function, ease of use for planning as well for navigating, transportability/ appearance, content, geographic information, effectiveness, efficiency, navigation assistance and security• A field test is necessary to ensure the effectiveness of the technology in avoiding or announcing potential obstacles such as sidewalk crossing ramp, damaged and congested sidewalk; sidewalk tilt (side slopes); thresholds at destination; verbal indication too soon or too late; incorrect indication; the arrow does not indicate the right direction; readjustment of the route needed; a lack of indication; and human intervention needed.

Conceptualization of Hand-TaPS to measure the subjective experience of dynamic hand orthoses in promoting functional recovery at home after stroke

BACKGROUND

Dynamic exoskeleton orthoses provide assistance needed to complete movements that would otherwise be impossible after stroke. Beyond the demonstration of their effectiveness, the subjective experience of dynamic orthoses also needs to be considered.

OBJECTIVE

To support functional recovery after stroke through the development of Hand-TaPS (Task Practice after Stroke), an instrument to evaluate dynamic hand orthoses in home therapy.

METHODS

Dynamic hand orthosis subject matter experts (N = 14), professionals and consumers, considered the items of PYTHEIA, a valid and reliable instrument merging well-tested, assistive technology (AT) assessment items with those tuned to the greater complexity of emerging technologies. Experts reflected on how each item aligned with their personal experience of dynamic orthosis use. Interpretative Phenomenological Analysis guided identification of themes.

RESULTS

Four themes (5/20 items) appraised highly relevant for Hand-TaPS. The remaining eight themes (15/20 items) were deemed in need of modification.

CONCLUSIONS

Dynamic hand orthoses constitute a special case of AT; the assistance they provide targets therapy, not ADLs. Our work to develop Hand-TaPS provides a clear example of the theoretical difference between rehabilitative and assistive technology and underscores the importance of consideration of how a device is used in its assessment.

Exploring Validity, Reliability, and Factor Analysis of the Quebec User Evaluation of Satisfaction with Assistive Technology in an Italian Population: A Cross-Sectional Study

This study explores validity, reliability, and factor analysis of the Quebec User Evaluation of Satisfaction with Assistive Technology (IT-QUEST) for users of assistive technology devices in an Italian population. It was administered to 75 people to determine which of the 24 original items were relevant to the Italian context using exploratory and confirmatory factor analyses (EFAs and CFAs) were conducted with internal consistency and test-retest reproducibility also evaluated. The EFA and CFA showed that the 24-item survey may have limited relevance to the Italian context. We individuated 12 significative items, divided into two subscales, as well as the original validation. The test-retest showed high values of the Intraclass Correlation Coefficient (ICC) (0.7-0.9), with a 0.812 ICC for the total scale providing support and evidence for Italian professionals to evaluate user satisfaction with assistive technology devices. This research also lays the foundation for developing a validation study of the IT-QUEST 2.0 that is relevant to the Italian culture. Further research may investigate psychometric properties involving more participants and different users of assistive technology devices.

A Systematic Review on Existing Measures for the Subjective Assessment of Rehabilitation and Assistive Robot Devices

The objective of the current study is to identify and classify outcome measures currently used for the assessment of rehabilitation or assistive robot devices. We conducted a systematic review of the literature using PubMed, MEDLINE, CIRRIE, and Scopus databases for studies that assessed rehabilitation or assistive robot devices from 1980 through January 2016. In all, 31 articles met all inclusion criteria. Tailor-made questionnaires were the most commonly used tool at 66.7%, while the great majority (93.9%) of the studies used nonvalidated instruments. The study reveals the absence of a standard scale which makes it difficult to compare the results from different researchers. There is a great need, therefore, for a valid and reliable instrument to be available for use by the intended end users for the subjective assessment of robot devices. The study concludes by identifying two scales that have been validated in general assistive technology devices and could support the scope of subjective assessment in rehabilitation or assistive robots (however, with limited coverage) and a new one called PYTHEIA, recently published. The latter intends to close the gap and help researchers and developers to evaluate, assess, and produce products that satisfy the real needs of the end users.

Translation and validation of the assistive technology device predisposition assessment in Greek in order to assess satisfaction with use of the selected assistive device

PURPOSE

To examine the Assistive Technology Device Predisposition Assessment scale and provide evidence of validity and reliability of the Greek version.

METHODS

We translated and adapted the original instrument in Greek according to the most well-known guidelines recommendations. Field test studies were conducted in a rehabilitation hospital to validate the appropriateness of the final results. Ratings of the different items were statistically analyzed. We recruited 115 subjects who were administered the Form E of the original questionnaire.

RESULTS

The experimental analysis conducted revealed a three subscales structure: (i) Adaptability, (ii) Fit to Use, and (iii) Socializing. According to the results of our study the three subscales measure different constructs. Reliability measures (ICC = 0.981, Pearson's correlation = 0.963, Cronbach's α = 0.701) yielded high values. Test-retest outcome showed great stability.

CONCLUSIONS

This is the first study, at least to the knowledge of the authors, which focuses merely on measuring the satisfaction of the users from the used assistive device, while exploring the Assistive Technology Device Predisposition Assessment - Device Form in such depth. According to the results, it is a stable, valid and reliable instrument and applicable to the Greek population. Thus, it can be used to measure the satisfaction of patients with assistive devices. Implications for Rehabilitation The paper explores the cultural adaptability and applicability of ATD PA - Device Form. ATD PA - Device Form can be used to assess user satisfaction by the selected assistive device. ATD PA - Device Form is a valid and reliable instrument in measuring users' satisfaction in Greekreality.
