Abstract

Background: Illness perceptions are an important factor affecting the prognosis of stroke patients. Evaluating the illness perceptions of stroke patients is of great importance for predicting their health behaviour and rehabilitation outcomes. However, there is no specific tool for assessing illness perceptions in stroke patients in China.

Objectives: The objective of this study is to translate the Stroke Illness Perception Questionnaire-Revised (SIPQ-R) into Chinese and to psychometrically test the Chinese version of the scale in the population of Chinese stroke patients.

Methods: This was a methodological study. We investigated 593 stroke patients in the neurology department of a hospital in China from March to September 2021. We translated the SIPQ-R and adapted it to the cultural context, after which we evaluated the reliability and validity of the Chinese version of SIPQ-R.

Results: Exploratory factor analysis identified eight common factors that accounted for 71.74% of the total variance, and the factor loadings ranged from 0.530 to 0.933. Confirmatory factor analysis confirmed the eight-factor structure (χ²/df = 1.765, root mean square error of approximation = 0.053, incremental fit index = 0.906, comparative fit index = 0.905 and Tucker-Lewis index = 0.900). Internal consistency was confirmed by a Cronbach's alpha coefficient of 0.982. The test-retest reliability was 0.762. The results showed good content validity (the scale level content validity index was 0.940, and the item level content validity index values ranged from 0.860 to 0.960). There were no missing responses and floor or ceiling effects. The standard error of measurement and the smallest detectable change for the SIPQ-R were 45.49 and 126.10, respectively.

Conclusions: The results of this study provide empirical evidence for the reliability and validity of the Chinese version of the SIPQ-R for stroke patients.

中文版脑卒中疾病认知问卷-修订版：对脑卒中患者进行信度和效度评估

背景：疾病认知是影响脑卒中患者预后的一个重要因素。评估脑卒中患者的疾病认知对预测他们的健康行为和康复效果具有重要意义。然而，在中国还没有专门评估脑卒中患者疾病认知的工具：本研究旨在将脑卒中疾病认知问卷-修订版（SIPQ-R）翻译成中文，并在中国脑卒中患者中对中文版量表进行心理测试：这是一项方法学研究。我们调查了 2021 年 3 月至 9 月在中国某医院神经内科就诊的 593 名脑卒中患者。我们翻译了 SIPQ-R，并根据文化背景对其进行了调整，然后评估了中文版 SIPQ-R 的信度和效度：探索性因子分析确定了八个共同因子，占总方差的 71.74%，因子载荷在 0.530 到 0.933 之间。确认性因素分析证实了八因素结构（χ2/df = 1.765，均方根近似误差 = 0.053，增量拟合指数 = 0.906，比较拟合指数 = 0.905，塔克-刘易斯指数 = 0.900）。Cronbach's alpha 系数为 0.982，证实了内部一致性。测试-再测可靠性为 0.762。结果显示内容效度良好（量表级内容效度指数为 0.940，项目级内容效度指数值介于 0.860 至 0.960 之间）。没有缺失回答，也没有下限或上限效应。SIPQ-R 的测量标准误差和可检测到的最小变化分别为 45.49 和 126.10：本研究结果为中文版脑卒中患者 SIPQ-R 的可靠性和有效性提供了实证证据。
