RATIONALE, AIMS, OBJECTIVES: The Illness Perception Questionnaire (IPQ) was designed as a measure of illness perception and has been used extensively for measuring the perceptions of people with physical illness. Latterly modified versions of the IPQ have been used to measure the illness perceptions of people with mental health problems and their carers. This study examined the utility of a modified version of the IPQ to measure changes in mental health practitioners' illness perceptions about schizophrenia after undertaking psychosocial intervention training.
A total of 245 mental health practitioners who undertook psychosocial intervention training completed a modified version of the IPQ before and after training. The structure of the questionnaire was tested using confirmatory factor analysis. The internal consistency of sub-scales embedded in the instrument was also examined.
The hypothesized structure failed to account for the data. Model fit indices revealed a poor fit to the data across all models evaluated. Cronbach's alpha revealed a number of sub-scales in the instrument to have mediocre internal consistency characteristics.
The modified version of the IPQ is not suitable for evaluating the impact of psychosocial intervention training on changes in illness perceptions of schizophrenia in mental health practitioners. However, the study has highlighted the need to develop a valid and reliable measure to assess the illness perceptions health professionals have of patients in their care.
病感问卷（Illness Perception Questionnaire，IPQ）旨在衡量疾病认知，已广泛应用于测量躯体疾病患者的认知。近来，IPQ 的改良版本已用于测量精神健康问题患者及其照顾者的疾病认知。本研究考察了改良版 IPQ 在衡量接受心理社会干预培训后精神卫生工作者对精神分裂症的疾病认知变化方面的效用。
共 245 名接受心理社会干预培训的精神卫生工作者在培训前后完成改良版 IPQ。采用验证性因子分析检验问卷结构。同时也检验了仪器中嵌入的子量表的内部一致性。
假设结构无法解释数据。所有评估模型的数据拟合指数均显示拟合度不佳。克朗巴赫 α 揭示了仪器中的一些子量表具有中等的内部一致性特征。
改良版 IPQ 不适用于评估心理社会干预培训对精神卫生工作者对精神分裂症疾病认知变化的影响。然而，该研究强调需要开发一种有效和可靠的衡量工具，以评估卫生专业人员对其照护患者的疾病认知。
