Health-related quality of life (HRQOL) questionnaires are increasingly used as outcome measures in research and clinical practice to assess treatment effectiveness in coronary heart disease (CHD) alongside traditional outcome measures. The Coronary Revascularisation Outcome Questionnaire (CROQ) is a patient-reported outcome measure (PROM) to evaluate health outcomes and HRQOL before and after coronary artery bypass grafting surgery (CABG) and percutaneous coronary intervention (PCI).
To translate the CROQ-PCI from English into Norwegian and test its psychometric properties.
Independent forward and backward translation was done following international guidelines. The CROQ was then pretested with both healthcare professionals and patients before the psychometric properties were field tested in a sample of patients who had undergone PCI. Psychometric testing included an evaluation of: acceptability; tests of scaling assumptions; reliability; content validity; construct validity based on within-scale analyses; and construct validity based on comparisons with external measures.
171 of 258 (66%) invited patients participated. The CROQ was acceptable to patients (low proportion of missing data and good response rate), reliable (good internal consistency and test-retest reliability for all scales), had good content validity (reported by both patients and healthcare professionals) and good construct validity (convergent validity with the SF-12 and Seattle Angina Questionnaire, known groups validity and factor analysis).
The Norwegian version of CROQ-PCI is a reliable and valid PROM for assessing HRQOL in CHD patients. Further testing of its responsiveness and ability to detect change is needed before recommending its use in Norwegian clinical practice and research.
与健康相关的生活质量（HRQOL）问卷在研究和临床实践中越来越多地被用作结果指标，与传统结果指标一起评估冠心病（CHD）的治疗效果。冠状动脉血运重建结果问卷（CROQ）是一种患者报告的结果指标（PROM），用于评估冠状动脉搭桥手术（CABG）和经皮冠状动脉介入治疗（PCI）前后的健康结果和HRQOL。
将CROQ-PCI从英文翻译成挪威文，并测试其心理测量特性。
按照国际指南进行独立的正向和反向翻译。然后在对医疗保健专业人员和患者进行预测试后，在接受PCI的患者样本中对心理测量特性进行现场测试。心理测量测试包括对以下方面的评估：可接受性；量表假设测试；可靠性；内容效度；基于量表内分析的结构效度；以及基于与外部测量比较的结构效度。
258名受邀患者中有171名（66%）参与。CROQ为患者所接受（缺失数据比例低且应答率良好），具有可靠性（所有量表的内部一致性良好且重测可靠性良好），具有良好的内容效度（患者和医疗保健专业人员均报告）以及良好的结构效度（与SF-12和西雅图心绞痛问卷的收敛效度、已知群体效度和因子分析）。
挪威版CROQ-PCI是评估冠心病患者HRQOL的可靠且有效的PROM。在推荐其用于挪威临床实践和研究之前，需要进一步测试其反应性和检测变化的能力。
