开发社会态度障碍和促进参与的物项库，并用既定工具对其进行验证。我们使用Rasch模型来识别不合适的项目和评定量表问题，校准项目，并开发关键表单和简短表单。计算社会态度障碍和促进题库与患者报告结果测量信息系统（PROMIS）社会健康域和NIH工具箱情感电池社会关系域的相关性，以评估收敛效度和分歧效度。社区居民前往三个学术医疗中心进行测试。参与者（N = 558）有原发性脑卒中、脊髓损伤或创伤性脑损伤（平均年龄47.0岁，SD = 16.0），使用五分制量表完成31个社会态度促进项目和51个障碍项目。不适用。项目银行衡量社会态度障碍和促进残疾人。将“从不”和“很少”两类量表组合后，有30个Facilitator项目符合Rasch模型，并证明了0.93的人信度。在对“从不”和“很少”两类评定量表进行分类后，有45个障碍项目符合Rasch模型，并证明了0.95的人信度。两个物项库的天花板和地板效应都可以忽略不计。促进项和障碍项与PROMIS和Toolbox量表呈负相关，具有收敛效度和发散效度的证据。研究结果支持社会态度促进因素和社会态度障碍题库的信度和效度。这些物项库允许调查人员和临床医生测量社会态度的感知，提供可以指导个人干预的信息，以减少障碍和促进促进者。社会态度库与PROMIS和工具箱变量之间的适度相关性为环境对社会健康和参与的影响的测量和理论提供了支持。
To develop item banks of social attitude barriers and facilitators to participation and validate them with established instruments. We used the Rasch model to identify misfitting items and rating scale problems, calibrate items, and develop KeyForms and short forms. Correlations between the Social Attitude Barriers and Facilitators item banks with the Patient-Reported Outcomes Measurement Information System (PROMIS) Social Health domain and NIH Toolbox Emotional Battery Social Relationships domain were computed to evaluate convergent and divergent validity. Community-dwelling individuals traveled to three academic medical centers for testing. Participants (N = 558) who had a primary impairment of stroke, spinal cord injury, or traumatic brain injury (mean age = 47.0 years, SD = 16.0) completed 31 social attitude facilitator and 51 barrier items using a five-point rating scale. Not applicable. Item banks to measure social attitude barriers and facilitators for people with disabilities. After combining the “never” and “rarely” rating scale categories, 30 Facilitator items fit the Rasch model and demonstrated person reliability of 0.93. After collapsing the “never” and “rarely” rating scale categories, 45 Barrier items fit the Rasch model and demonstrated person reliability of 0.95. Ceiling and floor effects were negligible for both item banks. Facilitators and Barriers item banks were negatively correlated, and these banks were moderately correlated with PROMIS and Toolbox measures, providing evidence of convergent and divergent validity. Findings support the reliability and validity of the Social Attitude Facilitators and Barriers item banks. These item banks allow investigators and clinicians to measure perceptions of social attitudes, providing information that can guide individual interventions to reduce barriers and promote facilitators. Moderate correlations between the Social Attitude banks and PROMIS and Toolbox variables provide support for the measurement and theory of environmental influences on social health and participation.
