OBJECTIVE: To study the psychometric qualities of a perceived self-efficacy in
wheeled mobility scale. DESIGN: Questionnaires. SUBJECTS: Forty-seven wheelchair
basketball players with spinal cord injury (elite n=25, recreational n=22, from 6
different countries). METHOD: Based on the literature, and expert's and
wheelchair user's comments, a new Self-Efficacy in Wheeled Mobility Scale (SEWM)1
was developed. Internal consistency (split-half and Cronbach's alpha) and
concurrent validity (correlating the Self-Efficacy in Wheeled Mobility Scale with
the Generalized Perceived Self-efficacy Scale (GSE) and the spinal cord injury
Exercise Self-Efficacy Scale (ESES)) were assessed. To evaluate the construct
validity, age, lesion level and completeness and time since injury between groups
of participants and their total scores were compared statistically. RESULTS:
Cronbach's alpha for the SEWM was 0.91, internal consistency was r=0.90.
Significant correlations between pairs of scales of the entire sample (SEWM-ESES:
0.60; SEWM-GSE: 0.50 (p<0.05; n= 47, 2-tailed) and of the sub-group comparison
(SEWM-ESES recreational r=0.61; elite r=0.73), demonstrated fair construct and
concurrent validity of the SEWM. CONCLUSION: The SEWM was found to be reliable
and valid in active spinal cord injury. A larger more diverse sample is needed to
support the psychometric qualities of the SEWM scale.
