Preoperative anxiety is common among the oncological surgical population. Due to its psychological and physiological detrimental effects, identifying and addressing it is of uttermost importance to improve anesthetic management and patient's outcomes. The aim of this study is to validate the Portuguese version of Amsterdam Preoperative Anxiety and Information Scale (APAIS) in the oncological population.
Following forward and backward translation of the original APAIS scale, further adaptation was obtained through cognitive interviewing. The resulting instrument was tested on the day before surgery on a sample of adult cancer surgical patients from a Portuguese oncology centre. Psychometric evaluation was derived from inter-item correlation, confirmatory factor analysis, Cronbach's alpha, correlation with comparative scales, receiver operating characteristic curve and Youden index.
109 patients (58 males, 51 females) were included. A three-dimensional model-anxiety about anesthesia, anxiety about surgery and desire for information, showed the best fit to the data. The questionnaire revealed high internal consistency (Cronbach alpha 0.81) and good inter-item correlation. Also, Portuguese APAIS correlated well with the gold standard anxiety scale. Therefore, the psychometric properties of this scale version make it a valid and reliable instrument. The optimal cutoff to maximize both sensitivity and specificity was 12 for the APAIS global anxiety score.
Portuguese APAIS version is an accurate tool to identify preoperative anxiety among cancer patients and might impact its management, from premedication choice to provision of information and reassurance about either anesthesia or surgery.
术前焦虑在肿瘤外科患者中很常见。由于其对心理和生理的不利影响，识别和处理这种焦虑对于改善麻醉管理和患者预后至关重要。本研究旨在验证阿姆斯特丹术前焦虑和信息量表（APAIS）的葡萄牙版本在肿瘤患者中的适用性。
在对原始 APAIS 量表进行正向和反向翻译后，通过认知访谈进一步进行了适应性调整。然后，在葡萄牙肿瘤中心的成年癌症手术患者中，于手术前一天对该量表进行了测试。通过项目间相关性、验证性因子分析、克朗巴赫α系数、与比较量表的相关性、受试者工作特征曲线和约登指数来评估心理测量学特性。
共纳入 109 例患者（男性 58 例，女性 51 例）。结果显示，一个三因素模型（对麻醉的焦虑、对手术的焦虑和对信息的渴望）最适合数据。该问卷显示出较高的内部一致性（克朗巴赫α系数 0.81）和良好的项目间相关性。此外，葡萄牙版 APAIS 与金标准焦虑量表相关性良好。因此，该量表版本具有良好的心理测量学特性，是一种有效且可靠的工具。最佳截断值为 12 分，可最大程度地提高 APAIS 总体焦虑评分的敏感性和特异性。
葡萄牙版 APAIS 是一种准确的工具，可用于识别癌症患者的术前焦虑，并可能影响其管理，从术前用药选择到提供信息和对麻醉或手术的保证。
