The Consultation and Relational Empathy (CARE) measure is recommended to evaluate the quality of care. However, there is no evidence that it is valid in rehabilitation. Aims were to examine the internal construct (factorial) validity of the CARE in the assessment of the patient-therapist relationship.
CARE data were part of an experimental study of acupuncture and different currently used acupuncture placebo controls, including 213 patients (age 66.8, SD 8.3, 58% female) with chronic stable hip or knee pain of mechanical origin, waiting for a joint replacement. CARE was completed two weeks into the study and on completion, two weeks later.
Cronbach alpha, factor analysis and Rasch analysis.
Internal construct validity was supported (82% of variance explained by the first factor; fit to the Rasch model χ(2) = 18.2, P = 0.57). CARE was unidimensional, had local independence of items, good item fit, absence of Differential Item Functioning and invariance over time. Three percent of people did not complete items 9 & 10.
CARE satisfied strict criteria for internal construct validity. An interval scale transformation is available that can be used in clinical practice and research. Further work is required to investigate item non-response and how this may be dealt with in clinical settings.
咨询和关系同理心 (CARE) 量表被推荐用于评估护理质量。然而，没有证据表明它在康复中是有效的。目的是检查 CARE 在评估患者-治疗师关系中的内部结构（因子）有效性。
CARE 数据是针灸和不同当前使用的针灸安慰剂对照的实验研究的一部分，包括 213 名患有机械性慢性稳定髋关节或膝关节疼痛的患者（年龄 66.8，标准差 8.3，58%为女性），等待关节置换。CARE 在研究开始后的两周内完成，并在两周后完成。
克朗巴赫阿尔法、因子分析和 Rasch 分析。
内部结构效度得到支持（第一个因素解释了 82%的方差；与 Rasch 模型拟合 χ(2) = 18.2，P = 0.57）。CARE 是单维的，项目具有局部独立性，项目拟合良好，不存在差异项目功能，且具有时间不变性。有 3%的人没有完成项目 9 和 10。
CARE 满足内部结构有效性的严格标准。提供了一个区间量表转换，可以在临床实践和研究中使用。需要进一步研究项目无反应以及如何在临床环境中处理这种情况。
