  • Towards an instrument targeting mobility-related participation: Nordic cross-national reliability
  • 2008

    • Objective: To investigate test-retest reliability and internal consistency of a new instrument for evaluation of mobility device interventions. Material and methods: The instrument comprised 4 scales and one summed index. Two test-retest interviews involved 147 mobility device users (mean age 60 years) with a broad range of functional limitations, living at home. Results: For 2 scales and the summed index the reliability was substantial or almost perfect (K 0.71/ K-W 0.76/intraclass correlation coefficient = 0.93; confidence interval = 0.90-0.95). The reliability of one scale was moderate (K-w 0.4 1), but after reduction of grades and combination with another scale, it was substantial (K-w 0.66). The reliability of the fourth scale was moderate (K-w 0.55). The internal consistency of 3 scales varied from a 0.63 to 0.76. Conclusion: Even thou,,h the test-retest reliability of all but one of the scales of the new instrument was substantial to almost perfect, this study demonstrated that revision is required. The challenges identified were probably due to the highly complex relationship between outdoor participation while using mobility devices and accessibility to the outdoor physical environment. Thus. based on the results of this study the instrument will be revised and subsequently launched as the "Nordic mobility-related participation outcome evaluation of assistive device intervention" (NOMO instrument). More research on the concept of mobility-related participation and the psychometric qualities of the instrument is required.

  • Documentation of and satisfaction with the service delivery process of electric powered scooters among adult users in different national contexts
  • 2013
  • Ingår i: Disability and Rehabilitation: Assistive Technology. - Taylor & Francis. - 1748-3115. ; 8, s. 151-160
  • Tidskriftsartikel (refereegranskat)abstract
    • The purpose of this study was to investigate how different service delivery systems for assistive devices were associated with the service delivery process (SDP) and user satisfaction in two national contexts when electric powered scooters were provided. Method: The study had a follow-up design based on a consecutive inclusion of 50 Danish and 86 Norwegian adults as they were about to be provided a scooter. A study-specific structured questionnaire for documentation of the SDP was administered. The Satisfaction with Assistive Technology Services was used for documenting user satisfaction with the SDP. Besides descriptive statistics, regression analysis was used to identify contributors of variance and predictors of user satisfaction. Results: The various steps of the SDP were carried out to a various degree. Significantly more total time was spent in the SDP in the Danish sample (p < 0.001). About 80% of the informants were satisfied/very satisfied with different aspects of the SDP. Time spent in the different steps was not associated with user satisfaction with the SDP. Conclusion: This study supports the assumption that structure of the service impacts on the SDP, but not that the process impacts on outcomes in terms of user satisfaction with the SDP. It may, however, be questioned whether this actually is an outcome.

  • Psychometric properties of the NOMO 1.0 tested among adult powered-mobility users
  • 2017
  • Ingår i: Canadian Journal of Occupational Therapy. - Canadian Association of Occupational Therapists. - 0008-4174. ; 84:1, s. 34-46
  • Tidskriftsartikel (refereegranskat)abstract
    • Background. The Nordic Mobility Related Outcome Evaluation of Assistive Device Intervention (NOMO 1.0) instrument evaluates the effectiveness of mobility devices in assessing mobility-related participation, captured by three scales (Need for Assistance, Frequency, and Ease/Difficulty) and one index (Participation Repertoire). Purpose. This study aimed to investigate a range of psychometric properties of the NOMO 1.0 in a sample of adult powered mobility device (PMD) users. Method. Data collected from PMD users (N = 248) in Denmark, Finland, and Norway as part of a larger study were analyzed using state-of-the-art statistical methods. Findings. The acceptability and applicability of the NOMO 1.0 items were generally within recommended values. Some floor/ceiling effects were found and the reliability was acceptable for only the Frequency scale. The factor analysis identified one component for the Need for Assistance scale and six components of the Frequency scale. Implications. The NOMO 1.0 should be used for research purposes and not for clinical practice. Better reliability should be established for the Need for Assistance and Ease/Difficulty scales prior to further psychometric testing to establish the validity of the NOMO 1.0.

  • Test-retest reliability and agreement of the Satisfaction with the Assistive Technology Services (SATS) instrument in two Nordic countries
  • 2014
  • Ingår i: Physiotherapy Theory and Practice. - Informa Healthcare. - 0959-3985. ; 30:5, s. 367-374
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: The purpose of this study was to investigate test-retest reliability, agreement, internal consistency, and floor- and ceiling effects of the Danish and Finnish versions of the Satisfaction with the Assistive Technology Services (SATS) instrument among adult users of powered wheelchairs (PWCs) or powered scooters (scooters). Method: Test-retest design, two telephone interviews 7-18 days apart of 40 informants, with mean age of 67.5 (SD 13.09) years in the Danish; and 54 informants with mean age of 55.6 (SD 12.09) years in the Finnish sample. Results: The intra-class correlation coefficient varied between 0.57 and 0.93 for items in the Danish and between 0.41 and 0.93 in the Finnish sample. The percentage agreement varied between 54.2 and 79.5 for items in the Danish and between 69.2 and 81.1 in the Finnish sample, while the Cronbach's alpha values varied between 0.87 and 0.96 in the two samples. A ceiling effect was found in all items of both samples. Conclusions: This study indicates that the SATS may be reliably administered for telephone interviews among adult PWC and scooter users, and give information about aspects of the service delivery process for quality development improvement purposes. Further psychometric testing of the SATS is required.
