“…The relationship among wheelchair confidence, wheelchair skills and life-space mobility is not unexpected, because self-efficacy has been hypothesized to moderate the relationship between capacity and performance (26). A similar relationship among wheelchair skills, lifespace mobility and frequency of participation has been found among facility residents who use wheelchairs as their primary means of mobility (20,39).…”

OBJECTIVES-To evaluate the relationship among the measures in a power wheelchair outcomes toolkit. DESIGN-We performed path analysis of cross-sectional data from self-report questionnaires and one objective measure. SETTING-Data were collected in six Canadian sites.PARTICIPANTS-A convenience sample of 128 power wheelchair users. The majority, 69 (53.9%), were female. Multiple sclerosis and spinal cord injury/disease were the most common diagnoses. RESULTS-Wheelchair confidence was independently associated with less difficulty with activity (β =0.08, 0.01

0.05) and participation (β=0.39, p<0.01), increased life space (β=0.09, p<0.03) and greater wheelchair skills (β=0.37, p<0.01) Less perceived difficulty with activity was independently associated with increased frequency of participation (β=0.30, p<0.01). Life space mobility was independently associated with increased frequency of participation ((β=0.31, p<0.01). Less difficulty with participation was independently associated with greater life-space mobility (β=0.32, p<0.01) and greater frequency of participation (β=0.13, p<0.01). INTERVENTIONS-NotCONCLUSION-This study provides empirical support for the measures included as part of the power wheelchair outcomes toolkit. They appear to provide complementary information on a variety of constructs related to power wheelchair use.

“…Evidence using Classical Test Theory methods indicates that the WheelCon measurements are both reliable and valid in manual wheelchair-users. 2 Furthermore, research using the WheelCon has shown that lower self-efficacy is associated with lower levels of participation frequency 3,4 and life-space mobility 5 in wheelchair-users aged 50 and older.…”

“…Despite foundational research supporting the WheelCon's measurement properties, and the scale's effective use in research and clinical settings, [2][3][4][5][6][7][8][9] further evaluation of the WheelCon's measurement properties using contemporary measurement methods (i.e., Rasch analyses) may address current limitations with the existing scale. For example, during the development of the WheelCon, 1 items were created that inquire about beliefs pertaining to both physical (e.g.…”

Objective-To compare the functioning of the Wheelchair Use Confidence Scale's 101-point response format with shortened 11-point formats, and to evaluate the scale's measurement properties using principal components and Rasch analyses.Design-Secondary analysis of cross-sectional data. Setting-Community.Participants-Volunteer participants from British Columbia, Ontario, Quebec, and Nova Scotia, Canada were manual wheelchair-users (n=220), ≥19 years of age, with ≥6 months experience with daily wheelchair-use, and no cognitive impairment. Intervention-None. Measurements-65-item Wheelchair Use Confidence Scale (WheelCon).Results-The 11-point response format outperformed the original 101-point format. Principal components analyses confirmed the presence of two dimensions: 1) Mobility efficacy; and 2) Selfmanagement efficacy. Thirteen items in the Mobility efficacy subscale, and eight items in the Selfmanagement efficacy subscale fit the Rasch Rating Scale model. Five items misfit the model developed using the 21-items from both subscales. In each of the 13-and 8-item subscales, and the 21-item short form, the two lowest and highest scores had internal consistency reliability estimates below 0.70; all other scores had reliability estimates above 0.70. Conclusion-TheWheelCon is comprised of two dimensions. The recoded measurements using a 0 to 10 response scale from the 13-item mobility and 8-item self-management efficacy subscales have good reliability as do the measurements from the 21-item WheelCon Short Form. The use of CIHR Author ManuscriptCIHR Author Manuscript CIHR Author Manuscript the subscales and/or the short form depends on the context in which they are being considered. Research to establish the reliability and validity of the measurements using the 0 to 10 response format is warranted. Keywordsself-efficacy; wheelchairs; measurement; Rasch analyses; principal components analysesThe Wheelchair Use Confidence Scale (WheelCon) 1 is a newly developed measurement scale that assesses self-efficacy with manual wheelchair-use in six conceptual areas including: 1) the physical environment (34 items); 2) activities performed (11 items); 3) knowledge and problem solving (8 items); 4) advocacy (4 items); 5) social situations (7 items); 6) and emotions (1 item). 1 For each item, individuals are asked, "As of now, how confident are you …" Each item is rated on a 0 (not confident) to 100 (completely confident) point response scale. A mean score is calculated with higher scores indicating higher selfefficacy. Evidence using Classical Test Theory methods indicates that the WheelCon measurements are both reliable and valid in manual wheelchair-users. 2 Furthermore, research using the WheelCon has shown that lower self-efficacy is associated with lower levels of participation frequency 3,4 and life-space mobility 5 in wheelchair-users aged 50 and older.Despite foundational research supporting the WheelCon's measurement properties, and the scale's effective use in research and clinical settings, 2-9 further evaluati...
