Preoperative anxiety is common and might affect surgical treatment outcomes. The aim was to translate and validate the Serbian version of the Amsterdam Preoperative Anxiety and Information Scale (APAIS).
Following translation and initial evaluation, the Serbian version (S-APAIS) was administered to 385 patients. Internal consistency, construct validity, prognostic criteria validity, and concurrent validity between S-APAIS and Visual Analogue Scale for Anxiety (VAS-A) were evaluated.
Factor analysis revealed two factors: APAIS-anesthesia (items 1, 2, 3) and APAIS-procedure (items 4, 5, 6). The whole scale, APAIS-anesthesia, and APAIS-procedure subscales showed an adequate level of internal consistency (Cronbach's αs: 0.787, 0.806, and 0.805, respectively). High concurrent validity was observed between APAIS-anesthesia and VAS-A (ρ = 0.628, p < .001). A moderate correlation was found between APAIS-procedure and VAS-A scale (ρ = 0.537, p < .001). At the cut-off point of 9, the area under the curve (AUC) of APAIS-anesthesia was 0.815 (95% CI: 0.77-0.85, p < .001). For the APAIS-procedure, AUC was 0.772 (95% CI: 0.73-0.81, p < .001) at the cut-off point of 8.
The structure of S-APAIS substantially differs from the original and allows separate measurement of anesthesia- and procedure-related anxieties. S-APAIS is a comprehensive, valid, and reliable instrument for the measurement of preoperative anxiety.
术前焦虑较为常见，可能会影响手术治疗效果。本研究旨在翻译并验证塞尔维亚版阿姆斯特丹术前焦虑和信息量表（APAIS）。
翻译和初步评估后，对 385 例患者施测塞尔维亚版 APAIS（S-APAIS）。评估 S-APAIS 的内部一致性、结构效度、预后标准效度和与视觉模拟焦虑量表（VAS-A）的同时效度。
因子分析显示存在 2 个因子：APAIS-麻醉（条目 1、2、3）和 APAIS-手术（条目 4、5、6）。全量表、APAIS-麻醉和 APAIS-手术分量表的内部一致性均处于较好水平（Cronbach's α 分别为 0.787、0.806 和 0.805）。APAIS-麻醉与 VAS-A 之间具有高度同时效度（ρ=0.628，p<0.001）。APAIS-手术与 VAS-A 量表之间存在中度相关性（ρ=0.537，p<0.001）。在截断值为 9 时，APAIS-麻醉的曲线下面积（AUC）为 0.815（95% CI：0.77-0.85，p<0.001）。对于 APAIS-手术，在截断值为 8 时，AUC 为 0.772（95% CI：0.73-0.81，p<0.001）。
S-APAIS 的结构与原始量表有较大差异，可分别测量麻醉和手术相关焦虑。S-APAIS 是一种全面、有效、可靠的术前焦虑测量工具。
