摘要目的：评价挪威版患者能力评定量表(PCRS)在颅脑损伤患者伤后12个月的心理测量学特性。方法：对148例轻、中、重度脑外伤患者入院时的人口学和损伤相关资料进行登记。在受伤后12个月，使用PCRS患者版和扩展的格拉斯哥结局量表(GOSE)评估活动能力和全球功能。研究采用描述性信度统计、因素分析和Rasch模型等方法，对PCRS的心理测量学特性进行了研究。外部效度采用GOSE量表进行评价。结果：PCRS可分为三个子量表，分别反映人际/情绪能力、认知能力和日常生活能力。三因素解决方案解释了56.6%的功能差异。内部一致性非常好，克朗巴赫指数(Cronbach‘sα)为0.95.第30项，“控制我的笑”，在任何因素上都没有超过0.40的负荷，也不符合Rasch模型。各分量表的外部效度均可接受，与Gose的相关系数在0.50~0.52之间。结论：挪威版PCRS是可靠的，具有可接受的结构和外部效度，可推荐用于脑外伤的后期阶段。对康复的影响患者能力评定量表似乎适合用于衡量不同严重程度的脑损伤患者的功能结果。该工具记录了自我报告的功能障碍、活动限制和参与限制。PCRS可作为创伤后晚期的测量工具，因此可能适合于颅脑损伤后的长期随访。
Abstract Purpose: To evaluate the psychometric properties of the Norwegian version of the Patient Competency Rating Scale (PCRS) in patients with traumatic brain injury (TBI) at 12 months post-injury. Methods: Demographic and injury-related data were registered upon admission to the hospital in 148 TBI patients with mild, moderate, or severe TBI. At 12 months post-injury, competency in activities and global functioning were measured using the PCRS patient version and the Glasgow Outcome Scale-Extended (GOSE). Descriptive reliability statistics, factor analysis and Rasch modeling were applied to explore the psychometric properties of the PCRS. External validity was evaluated using the GOSE. Results: The PCRS can be divided into three subscales that reflect interpersonal/emotional, cognitive, and activities of daily living competency. The three-factor solution explained 56.6% of the variance in functioning. The internal consistency was very good, with a Cronbach’s α of 0.95. Item 30, “controlling my laughter”, did not load above 0.40 on any factors and did not fit the Rasch model. The external validity of the subscales was acceptable, with correlations between 0.50 and 0.52 with the GOSE. Conclusion: The Norwegian version of the PCRS is reliable, has an acceptable construct and external validity, and can be recommended for use during the later phases of TBI. Implications for Rehabilitation The Patient Competency Rating Scale appears appropriate for measuring functional outcome across TBI severity groups. The instrument captures self-reported functional impairments, activity limitations and participation restrictions. The PCRS may be applied as a measurement tool at a late phase post-injury and may thus be suited for long-term follow-up after TBI.
