To examine the measurement properties of the French-Canadian version of the Life-Space Assessment questionnaire (LSA-F) for power mobility device (PMD) users.
Content validity, test-retest reliability of telephone interviews (2-week interval) and applicability were examined with PMD users presenting neurological, orthopedic or medically complex conditions. Translation/back-translation from English to French and cultural adaptation was performed and pretested with five bilingual users. Test-retest reliability was examined with 40 French-speaking users, age 50 and over, who had been using a subsidized PMD for 2-15 months. Audio-taped interviews were coded to judge content validity and applicability.
Content validity results confirmed equivalent meaning for most questions. The test-retest reliability was excellent for the composite score (intra-class correlation coefficient = 0.87) and revealed moderate to substantial concordance for 18/20 items (k = 0.47-0.73; P(a) > 57.5%). The applicability of the LSA-F is satisfactory considering an acceptable burden of assessment, low refusal of the telephone interview format (8%; n = 4), reasonable administration time (9.2 +/- 3.9 min) and a normally distributed composite score.
The LSA-F is a valid measure with regards to its content, stable over a period of 2 weeks and applicable for a population of middle-aged and older French-Canadian speaking adults who use PMDs.
In 1998, 11.8% of the Quebec population over 15 years showed mobility problems and 2.3% of that group revealed that their needs were not met. The same year, the Régie de l'assurance-maladie du Québec distributed more than 4,500 wheelchairs and repaired some 30,000 others, at a cost of over $20 million. The recycling of wheelchairs is seen as a solution for improving this situation. This paper presents an evaluation of a wheelchair recycling program.
Three groups of participants involved in the recycling of wheelchairs contributed to the gathering of information. These were: personnel (n = 9), occupational therapists in the community (n = 5) and users of refurbished wheelchairs (n = 20).
A participative and qualitative research approach was conducted with the 1st group. The results outline the inefficacy of the process on the structural level (e.g. not enough resources to collect unused wheelchairs), operational level (e.g. absence of norms to recycle), strategic level (e.g. absence of policy to encourage people to give back their unused wheelchair) and systemic level (e.g. the state is not imputable). A quantitative approach with the 2nd and 3rd groups revealed high satisfaction with regard to the efficacy, appearance, safety, durability and comfort as well as the delivery and follow-up services rendered.
The evaluation procedure herein proposed can be customized to fit other contexts and provides policy-makers with quick access to field data to help them choose the appropriate course of action.
