Obsessions - recurrent unwanted intrusive thoughts - are one of the two pillars of the Obsessive Compulsive Disorder (OCD). Although OCD has been reported across many different cultures, research on these cultural variations is hampered by the lack of cross-culturally sound instruments to assess intrusive thoughts. The aim of the current study is to investigate the psychometric properties of the recently developed Leuven Obsessional Intrusions Instrument (LOII) in two different cultural contexts. Turkish (N = 663) and Belgian (N = 496) participants were sampled from non-clinical student populations. Results from confirmatory factor analyses yielded a shortened version of the LOII (i.e., LOII-R) with a four-factor solution - aggressive, sexual, and contamination intrusions, and 'just-right' doubts - as the best fitting model across both cultures. The model met most criteria for strong measurement invariance, and proved to be both valid and reliable. The results of this study suggest that the LOII-R is a good candidate for cross-cultural studies on obsessional intrusions.
强迫观念——反复出现的不必要的侵入性想法——是强迫症（OCD）的两大支柱之一。尽管在许多不同文化中都有强迫症的报道，但由于缺乏跨文化适用的工具来评估侵入性想法，对这些文化差异的研究受到了阻碍。本研究的目的是在两种不同文化背景下，调查最近开发的鲁汶强迫性侵入量表（LOII）的心理测量特性。土耳其（N = 663）和比利时（N = 496）的参与者来自非临床学生群体。验证性因素分析的结果产生了一个简化版的LOII（即LOII-R），其具有一个四因素模型——攻击性、性和污染侵入以及“恰到好处”的怀疑——作为两种文化中最合适的模型。该模型符合强测量不变性的大多数标准，并且被证明是有效且可靠的。本研究结果表明，LOII-R是用于强迫性侵入跨文化研究的一个很好的候选工具。
