背景对医疗保健提供者患者激活量表（HP-PAS）的修改，该量表评估了对使用以患者为中心的方法（PCA）的重要性的态度，目的从HP-PAS开发的量表的内容效度和可靠性，以评估自我报告的患者依从性，方法以86名日本物理治疗师为研究对象，匿名调查其中，53人在一项命名调查中完成可靠性评估。修改了HP-PAS，为每个项目标记最合适的频率，创建了一个11点量表。对于有效性评估，参与者将每个项目分配给以治疗师为中心的方法或使用5分制的PCA。当分数4和5（“可能”或“肯定”PCA）相对于分数总数的比例> 50%时，考虑内容效度。当在11分量表上得分分别为10和0的响应比例> 20%时，考虑天花板和地板效应。结果在20个条目中，剔除6个条目，形成了一个包含14个条目的以患者为中心的物理治疗依从性量表（SAPCPTS），该量表具有良好的内部一致性（Cronbach’s α= 0.95，95%CI = 0.93-0.96）和重测信度（ICC = 0.84，95%CI = 0.75-0.91）。
BackgroundModifications to the Healthcare Providers Patient-Activation Scale (HP-PAS), which evaluates attitudes toward the importance of using a patient-centered approach (PCA), are required.PurposeContent validity and reliabilities of a scale developed from the HP-PAS to evaluate self-reported adherence to patient-centered physical therapy were preliminarily investigated.MethodsA total of 86 Japanese physical therapists completed the validity assessments in an anonymous survey. Among them, 53 completed the reliability assessments in a named survey. The HP-PAS was modified to mark the most suitable frequency for each item, creating an 11-point scale. For the validity assessments, the participants assigned each item to a therapist-centered approach or PCA using a 5-point scale. Content validity was considered when the proportion of scores 4 and 5 (“possibly” or “definitely” a PCA) with respect to the total number of scores was > 50%. Ceiling and flooring effects were considered when the response proportions of scores of 10 and 0, respectively, on an 11-point scale were > 20%. Items with an intraclass correlation coefficient (ICC) < 0.4 in the test–retest reliability from the item list were excluded.ResultsOf the 20 items, 6 were excluded, developing a 14-item self-reported adherence to a patient-centered physical therapy scale (SAPCPTS), which exhibited good internal consistency (Cronbach’sα= 0.95, 95% confident intervals [CIs] = 0.93–0.96) and test–retest reliability (ICC = 0.84, 95% CIs = 0.75–0.91).ConclusionThis study identified that the 14-item SAPCPTS demonstrated preliminary evidence of content validity and reliability.
