“…The LSA has been characterized as a participation measure in the literature 13,27,28 and could fulfill a need for outcome measures appropriate for persons with SCI regardless of their means of mobility. 29 Life wheeled mobility, either manual (LSA = 46.99) 16 or power (LSA = 33), 14 but smaller than that reported for a population-based study of persons aged 15 to 90 years (LSA = 98.3). 30 Despite the younger age of our sample, their LSA scores were comparable to the average reported for community-dwelling older adults with a mean age of 75 years (64.1 ± 24.9).…”

Objectives: To examine the Life Space Assessment (LSA) in persons with spinal cord injury (SCI), exploring its psychometric properties, differences between persons with cervical versus thoracolumbar injuries, and cutoff score differentiating a restricted from an unrestricted life space. Method: We conducted a test-retest reliability study in a community setting involving 50 persons with SCI (25 injured above C7, 25 injured below T1). Data were collected in 2 phone interviews approximately 9 days apart using the LSA. Results: Mean LSA scores were 66 ± 25 (n = 50): 62 ± 23 for the cervical group, and 70 ± 25 for the thoracolumbar group. Scores were not significantly different between phone interviews [t (49) = 0.379, p = .706] or between groups [t (48) = -1.214, p = .231]. Test-retest reliability intraclass correlation coefficient (ICC) was 0.876 (95% CI, 0.792-0.928). Spearman's rho correlations between the LSA and Reintegration to Normal Living Index total and subscores ranged from .509 to .538 (p < .001). LSA scores were normally distributed. The minimum detectable change was approximately 23 points. A cutoff score of 78.5 (sensitivity 76.9%, specificity 81.1%) differentiated between persons with a restricted from an unrestricted life space if equipment and personal assistance were not needed for mobility. If equipment was needed, the cutoff score was found to be 49 (sensitivity of 90%, specificity of 90%). Conclusions: The LSA is a reliable and valid measure of life space in persons with SCI and can be used to identify persons with a restricted life space who may be at increased risk of mobility disability.

“…[11][12][13][14] Persons with SCI are certainly at risk for mobility disability. Although the LSA has been examined in populations that included persons with SCI, 15,16 to our knowledge no investigations have examined the LSA in a population limited to SCI. Such studies are important to ensure the appropriateness of outcome tool application.…”

“…Specifically, we now know that: there is a high prevalence of low wheelchair confidence among adult manual wheelchair users; 16 wheelchair confidence influences life-space mobility 17 and participation 18,19 among community-dwelling manual wheelchair users; wheelchair confidence is a modifiable barrier to wheelchair use among both older adults 20 and occupational therapy students; 21 and there is a discordance between wheelchair confidence and wheelchair skill among adult manual wheelchair users. 16 These findings are of particular significance given that wheelchairs are prescribed to improve mobility and enhance one's ability to participate in their chosen daily activities, important rehabilitation outcomes.…”

Purpose-The aim of this study was to adapt the WheelCon-M, an outcome measure used to assess confidence with manual wheelchair use, into a version that is applicable for power wheelchair users (WheelCon-P).Methods-Adaptation of the WheelCon-M into the WheelCon-P occurred in two phases: 1) item modification was conducted using focus groups and 2) item refinement was done using a think aloud process.Results-The health care professionals (n=12) were mostly female, mostly occupational therapists, and practiced an average of 14 years. The power wheelchair users (n=8) were 50% men with an average of 8 years of power wheelchair experience and a range of diagnoses. In phase 1, of the 63 WheelCon-M items, 6 remained the same, 18 were removed, 38 modified, and 15 new items added to develop the WheelCon-P. In phase 2, 15 WheelCon-P items were refined.Conclusions-This study resulted in the modification of the WheelCon-M into the WheelCon-P, a 59-item, self-report outcome measure designed to assess confidence with power wheelchair use. The next step in the evolution of this promising new measure is the assessment of its measurement properties.

“…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...
