To evaluate the psychometric properties and validity of an expanded set of community enfranchisement items that are suitable for computer adaptive testing.
Survey.
Community setting.
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.
None.
Community enfranchisement.
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.
Importance of participation and control over participation define 2 distinct sets of participation enfranchisement. Preliminary evidence supports their validity.
评估一套适合计算机自适应测试的扩展社区赋权项目的心理测量学特性和效度。
调查。
社区环境。
从在线小组生成公司（51%）、前康复住院患者（18%）、残疾社区组织（13%）、康复患者登记处（10%）和创伤性脑损伤和脊髓损伤模型系统设施（8%）招募了 1163 名残疾个体。纳入标准为自我认定的残疾、年龄≥18 岁，以及能够阅读和说英语的能力。
无。
社区赋权。
对 48 个赋权项目进行的探索性和验证性因子分析表明，存在两个不同的项目子集：（1）参与的重要性，（2）参与的控制。残差的主成分分析表明，这两个项目集是单维的。评分量表分析提供了证据表明，这两个项目集符合 Rasch 模型。重要性和控制与彼此以及与残疾严重程度中度相关。
参与的重要性和对参与的控制定义了两个不同的参与赋权集。初步证据支持其有效性。
