The study aimed at providing the psychometric properties of Polish version of Peters et al. Delusion Inventory (PPDI) (1999) and assessing the prevalence of delusion-like experiences among healthy subjects in the Polish population.
Polish version of PDI was developed on the basis of back translation procedure. The scale was completed by 421 adult subjects. On the basis of the scores, the factor analysis, the reliability of the scale and the frequency of delusion-like experiences in the Polish population were calculated.
The Polish version of Peters et al. Delusion Inventory has satisfactory reliability (Cronbach's alpha ranged from 0.084 to 0.87). The examination of scree plot suggests a single factor solution. The participants confirmed the incidence of, on average, 12.5 (SD=6.9), out of 40 different experiences measured using PDI. In the current study the most frequently asserted delusion-like belief is that people say things with double meaning (79.8% of participants), while the least likely beliefs were those similar to delusions observed among psychiatric patients (2.37% of participants).
The Polish version of PDI is characterised by good psychometric properties and can be used for delusion-like experiences assessment in non-clinical population. The frequency of delusion-like experiences in the Polish population varies from 2 to 80% depending on their content.
本研究旨在提供彼得斯等人的《妄想量表》（PPDI）波兰语版本（1999年）的心理测量特性，并评估波兰人群中健康受试者的类妄想体验患病率。
PPDI波兰语版本是在回译程序的基础上编制的。421名成年受试者完成了该量表。根据得分，计算了因子分析、量表的信度以及波兰人群中类妄想体验的频率。
彼得斯等人的《妄想量表》波兰语版本具有令人满意的信度（克朗巴哈系数范围为0.084至0.87）。碎石图检验表明采用单因素解决方案。参与者确认，在使用PPDI测量的40种不同体验中，平均有12.5种（标准差=6.9）。在当前研究中，最常被断言的类妄想信念是人们说话有双重含义（79.8%的参与者），而最不可能的信念是那些与精神科患者中观察到的妄想相似的信念（2.37%的参与者）。
PPDI波兰语版本具有良好的心理测量特性，可用于非临床人群的类妄想体验评估。波兰人群中类妄想体验的频率因内容而异，从2%到80%不等。
