Objective
To calibrate and validate the Benin version of ABILOCO, a Rasch-built scale developed to assess locomotion ability in stroke patients.
Design : Prospective study and questionnaire development.
Setting : Rehabilitation centers.
Participants : Stroke patients (N=230; mean age + SD, 51.1+11.6y; 64.3% men).
Main Outcome Measures :
Participants completed a preliminary list of 36 items including the 13 items of ABILOCO. Items were scored as “impossible,” “difficult,” or “easy.” The mobility subdomain of FIM (FIM-mobility), the Functional Ambulation Classification (FAC), the 6-minute walk test (6MWT), and the 10-meter walk test (10MWT) were used to evaluate and elucidate the validity of the ABILOCO-Benin scale.
Results :
Successive Rasch analyses led to the selection of 15 items that define a unidimensional, invariant, and linear measure of locomotion ability in stroke patients. This modified version of the ABILOCO scale, named ABILOCO-Benin, showed an excellent internal consistency, with a Person Separation Index of .93, and excellent test-retest reliability with high intraclass correlation coefficients of .95 (P<.001 for item difficulty and .93 subject measures. it also presented good construct validity compared with fac fim-mobility p>
Conclusions :
ABILOCO-Benin presents good psychometric properties. It allows valid, reliable, and objective measurements of locomotion ability in stroke patients. |
