OBJECTIVE: To evaluate the psychometric properties and validity of an expanded
set of community enfranchisement items that are suitable for computer adaptive
testing. DESIGN: Survey. SETTING: Community setting. PARTICIPANTS: Individuals
with disabilities (N=1163) were recruited from an online panel generation company
(51%), former rehabilitation inpatients (18%), disability community organizations
(13%), a registry of rehabilitation patients (10%), and Traumatic Brain Injury
and Spinal Cord Injury Model System facilities (8%). Inclusion criteria were a
self-identified disability, aged >/=18 years, and the ability to read and speak
English. INTERVENTIONS: None. MAIN OUTCOME MEASURE: Community enfranchisement.
RESULTS: Exploratory and confirmatory factor analyses of the 48 enfranchisement
items suggested 2 distinct subsets of items: (1) importance of participation and
(2) control over participation. Principal components analysis of the residuals
suggested that the 2 item sets are unidimensional. Rating scale analysis provided
evidence that the 2 item sets fit the Rasch model. Importance and control were
moderately correlated with each other and with disability severity. CONCLUSIONS:
Importance of participation and control over participation define 2 distinct sets
of participation enfranchisement. Preliminary evidence supports their validity.
