Many individuals with Parkinson's disease are not diagnosed and treated. Attitudes about aging and related help-seeking may affect the timely diagnosis of Parkinson's disease. Our objectives were to develop measures of older adults' expectations regarding movement with aging, specifically related to parkinsonism, and their beliefs about seeking healthcare for the diagnosis and treatment of parkinsonism.
We established content and face validity from interviews with experts, review of the literature, and pre-testing with key informants. Two 9-item instruments resulted: Expectations Regarding Movement (ERM) and Healthcare Seeking Beliefs for parkinsonism (HSB). These instruments were administered to 210 older adults at senior centers to investigate internal consistency and construct validity.
192 (91%) of the older adults completed more than 90% of the survey. The mean age was 76; 17 (9%) reported parkinsonism. Both scales demonstrated good internal consistency (α = 0.90). Factor analysis supported construct validity of the ERM and HSB scores. Older age, lower education, worse self-reported health and African American race each were associated with lower ERM scores, but not HSB scores.
The ERM, a brief measure of expectations regarding movement with aging, shows reliability and validity. This scale may be useful in identifying older adults at increased risk for under-identification of Parkinson's disease. Further work is needed to measure healthcare seeking for parkinsonism.
许多帕金森病患者未被诊断和治疗。对衰老的态度和相关的寻求帮助的意愿可能会影响帕金森病的及时诊断。我们的目标是开发衡量老年人对衰老时运动的预期的措施，特别是与帕金森病相关的预期，以及他们对寻求医疗保健以诊断和治疗帕金森病的信念。
我们通过与专家的访谈、文献回顾和关键知情人的预测试，确定了内容和表面效度。由此产生了两个 9 项工具：运动预期量表（ERM）和帕金森病医疗保健寻求信念量表（HSB）。这两个工具在老年人中心的 210 名老年人中进行了调查，以研究内部一致性和结构有效性。
192 名（91%）老年人完成了超过 90%的调查。平均年龄为 76 岁；17 名（9%）报告有帕金森病。这两个量表都显示出良好的内部一致性（α=0.90）。因子分析支持 ERM 和 HSB 评分的结构有效性。年龄较大、受教育程度较低、自我报告的健康状况较差和非裔美国人种族都与较低的 ERM 评分相关，但与 HSB 评分无关。
ERM 是一种衡量对衰老时运动的预期的简短工具，具有可靠性和有效性。该量表可能有助于识别帕金森病识别不足风险较高的老年人。还需要进一步的工作来衡量帕金森病的医疗保健寻求。
