目的：设计：临床环境中的横断面问卷调查研究，在家中完成后通过邮件返回的重测问卷。设置：地区多发性硬化症（MS）门诊或英国一家大型神经科学中心的临床试验单位（CTU）。100人与MS参加沃尔顿中心神经病学和神经外科和克拉特布里奇医院，维拉尔，作为outpatients.Methods：认知功能障碍的患者被排除在最初的临床评估。要求患者提供人口统计学数据，并完成自我效能量表沿着以下经验证的量表：医院焦虑和抑郁量表、Rosenberg自尊量表、影响、耻辱和掌握以及兰金量表。结果：编制了一个由控制和个人能动性两个维度组成的11项自我效能量表。使用Cronbach的内部一致性的α分析（α = 0.81）的量表的有效性进行了确认。两周内量表的重测信度是可以接受的，组内相关系数为0.79。结构效度采用皮尔逊积差相关系数进行了研究，结果显示与抑郁（r = -0.52）、焦虑（r = -0.50）和掌握（r = 0.73）显著相关。多元回归分析表明，这些因素解释了70%的变异的自我效能量表上的分数，掌握，焦虑和自觉disability的分数是独立significant.Conclusion：心理测量学性能的评估，这种新的自我效能量表表明，它具有良好的效度和信度在多发性硬化症患者。
Objective: To develop a scale to measure self-efficacy in neurologically impaired patients with multiple sclerosis and to assess the scale's psychometric properties.Design: Cross-sectional questionnaire study in a clinical setting, the retest questionnaire returned by mail after completion at home.Setting: Regional multiple sclerosis (MS) outpatient clinic or the Clinical Trials Unit (CTU) at a large neuroscience centre in the UK.Subjects: One hundred persons with MS attending the Walton Centre for Neurology and Neurosurgery and Clatterbridge Hospital, Wirral, as outpatients.Methods: Cognitively impaired patients were excluded at an initial clinic assessment. Patients were asked to provide demographic data and complete the self-efficacy scale along with the following Validated scales: Hospital Anxiety and Depression Scale, Rosenberg Self-Esteem Scale, Impact, Stigma and Mastery and Rankin Scales. The Rankin Scale and Barthel index were also assessed by the physician.Results: A new 11-item self-efficacy scale was constructed consisting of two domains of control and personal agency. The validity of the scale was confirmed using Cronbach's alpha analysis of internal consistency (alpha = 0.81). The test-retest reliability of the scale over two weeks was acceptable with an intraclass correlation coefficient of 0.79. Construct validity was investigated using Pearson's product moment correlation coefficient resulting in significant correlations with depression (r = -0.52) anxiety (r = -0.50) and mastery (r = 0.73). Multiple regression analysis demonstrated that these factors accounted for 70% of the variance of scores on the self-efficacy scale, with scores on mastery, anxiety and perceived disability being independently significant.Conclusion: Assessment of the psychometric properties of this new self-efficacy scale suggest that it possesses good validity and reliability in patients with multiple sclerosis.
