This investigation aimed to estimate reliability of the WHOQOL-BREF questionnaire and quality of life of patients after PCI or CABG surgery.
In this cross-sectional study, 268 patients after PCI or CABG surgery were studied in East Kazakhstan and Pavlodar regions of Kazakhstan from September to December 2019. The Russian version of the World Health Organization Quality of Life Instrument, Short Form (WHOQOL-BREF) was used to measure their quality of life. Cronbach's alpha coefficient, Pearson's correlation coefficient, paired t-test, independent t-test, and linear regression model were used to analyze the data.
The mean age of the participants was 60.8 ± 9.2 years, while most of them were male (75.0 %). The overall observed Cronbach's alpha coefficient for the WHOQOL-BREF was 0.842, ranging from 0.668 to 0.764 in its four domains. The total mean score of the respondents on the WHOQOL-BREF was 13.97. The highest and lowest mean scores were observed in the environmental domain (15.22) and the physical health domain (13.00), respectively.
The WHOQOL-BREF questionnaire has a good reliability in characterizing the quality of life of patients after PCI or CABG surgery. Patients after PCI or CABG surgery had a relatively moderate quality of life (Tab. 6, Ref. 23).
本研究旨在评估 WHOQOL-BREF 问卷的信度和经皮冠状动脉介入治疗（PCI）或冠状动脉旁路移植术（CABG）后患者的生活质量。
本横断面研究于 2019 年 9 月至 12 月在哈萨克斯坦东哈萨克斯坦州和巴甫洛达尔州入组了 268 例 PCI 或 CABG 术后患者。采用世界卫生组织生活质量量表简表（WHOQOL-BREF）的俄语版评估患者的生活质量。使用克朗巴赫α系数、皮尔逊相关系数、配对 t 检验、独立 t 检验和线性回归模型进行数据分析。
参与者的平均年龄为 60.8 ± 9.2 岁，其中大多数为男性（75.0 %）。WHOQOL-BREF 的总体观察克朗巴赫α系数为 0.842，四个领域的克朗巴赫α系数范围为 0.668 至 0.764。受访者在 WHOQOL-BREF 上的总平均得分为 13.97。得分最高和最低的分别是环境领域（15.22）和身体健康领域（13.00）。
WHOQOL-BREF 问卷在描述 PCI 或 CABG 术后患者的生活质量方面具有良好的信度。PCI 或 CABG 术后患者的生活质量处于中等水平（表 6，参考文献 23）。
