The Illness Perception Questionnaire-Revised (IPQ-R) has commonly been used to measure illness representations of various diseases. The present study examined whether the original factor structure of the IPQ-R could be confirmed or a new structure could be established on substance dependence among injecting drug users (IDU) in China.
A total of 257 IDU completed the 38-item IPQ-R on substance dependence.
Results of confirmatory factor analysis (CFA) showed that the 7-factor structure as proposed by the original IPQ-R reported poor goodness-of-fit statistics. Although removal of 12 items improved the model fit, the goodness-of-fit statistics were still below acceptable standards. Furthermore, factors obtained from the exploratory factor analysis (EFA) of the IPQ-R were not interpretable.
The CFA found that the original IPQ-R factor structure fit the data poorly. Factors derived from EFA were also not interpretable. Use of the IPQ-R for assessment of illness representations of substance dependence among IDU in China is cautioned until further validation.
修订后的疾病认知问卷（IPQ-R）常用于测量各种疾病的疾病认知。本研究探讨了IPQ-R的原始因子结构在中国注射吸毒者（IDU）的物质依赖方面是否能够得到证实，或者是否能够建立一个新的结构。
共有257名注射吸毒者完成了关于物质依赖的38项IPQ-R问卷。
验证性因子分析（CFA）结果显示，原始IPQ-R提出的7因子结构的拟合优度统计结果较差。虽然删除12个项目改善了模型拟合，但拟合优度统计结果仍低于可接受标准。此外，从IPQ-R的探索性因子分析（EFA）中获得的因子无法解释。
CFA发现原始IPQ-R因子结构对数据的拟合较差。EFA得出的因子也无法解释。在进一步验证之前，谨慎使用IPQ-R评估中国注射吸毒者的物质依赖疾病认知。
