This study aimed to evaluate the psychometric properties of the Persian version of the Paranoia Scale (PS) in a sample of university students. Specifically, we assessed its structural validity, measurement invariance, reliability, and other psychometric characteristics to determine suitability for use in Persian-speaking populations.
A total of 470 university students were recruited using a convenience sampling method over a six-month period. Participants completed the Paranoia Scale and other measures which were conceptually related to the concept of paranoia. Data analysis comprised descriptive statistics, correlation coefficients, measurement invariance, as well as principal component analysis and confirmatory factor analysis.
Principal component analysis (PCA) revealed a two-factor structure, comprising "Mistrust Thoughts" and "Persecutory Ideas." Subsequently, a second-order confirmatory factor analysis (CFA) demonstrated an acceptable model fit, supporting the scale's structural validity.
Paranoid thoughts in non-clinical populations are phenomena of interest in their own right and may increases our understanding of delusions. Therefore, the Paranoia Scale suggest as a valid and reliable instrument with good internal consistency.
本研究旨在评估偏执量表（PS）波斯语版本在大学生样本中的心理测量特性。具体而言，我们评估了其结构效度、测量不变性、信度及其他心理测量特征，以确定其在说波斯语人群中的适用性。
在六个月的时间里，采用便利抽样法共招募了470名大学生。参与者完成了偏执量表及其他与偏执概念在概念上相关的测量。数据分析包括描述性统计、相关系数、测量不变性，以及主成分分析和验证性因素分析。
主成分分析（PCA）揭示了一个双因素结构，包括“不信任想法”和“迫害观念”。随后，二阶验证性因素分析（CFA）显示模型拟合可接受，支持了该量表的结构效度。
非临床人群中的偏执想法本身就是有趣的现象，可能会增进我们对妄想的理解。因此，偏执量表被认为是一种有效且可靠的工具，具有良好的内部一致性。
