Obsessive-compulsive (OC) tendencies refer to obsessions and compulsions in a nonclinical group, which are risk factors for obsessive-compulsive disorder (OCD). OC tendencies and OC symptoms are mainly assessed using five factors: ordering, obsessions, cleaning, hoarding, and checking. However, since hoarding is now classified as an independent diagnosis in the DSM-V, this factor was not included and was instead replaced by indecisiveness. Furthermore, many established scales used for measuring OC tendencies were originally created for OCD patients; thus, they cannot adequately capture OC tendencies. Therefore, this study aimed to develop a scale to assess OC tendencies among Japanese university students with a revised five-factor structure: ordering, obsessions, cleaning, indecisiveness, and checking. We examined the factor structure, reliability, criterion-related validity, and convergent validity of the OC tendencies scale by administering two surveys. In Survey 1 ( = 216), an exploratory factor analysis (EFA) was conducted to examine the criterion-related and convergent validity and reliability of the OC tendencies scale. In Survey 2 ( = 202), a confirmatory factor analysis (CFA) was conducted. EFA and CFA utilized a five-factor structure comprising checking, ordering, indecisiveness, cleaning, and obsessions. Correlations with other scales indicated that the OC tendencies scale had efficient convergent validity, criterion-related validity, internal consistency, and test-retest reliability. This study validated the five-factor structure of OC tendency in Japanese university students. However, indecisiveness was also strongly correlated with trait-anxiety. As this scale is easy to administer among large groups, it has the potential to contribute to mental health support for university students by measuring OC tendencies experienced on a daily basis, which have not been adequately measured in the past.
强迫倾向是指非临床群体中的强迫观念和强迫行为，它们是强迫症（OCD）的风险因素。强迫倾向和强迫症状主要通过五个因素进行评估：条理、强迫观念、清洁、囤积和检查。然而，由于囤积现在在《精神疾病诊断与统计手册》第五版（DSM-V）中被归类为一种独立的诊断，该因素未被纳入，而是被优柔寡断所取代。此外，许多用于测量强迫倾向的既定量表最初是为强迫症患者编制的；因此，它们无法充分捕捉强迫倾向。因此，本研究旨在开发一种量表，以评估具有修订后的五因素结构（条理、强迫观念、清洁、优柔寡断和检查）的日本大学生的强迫倾向。我们通过进行两项调查来检验强迫倾向量表的因素结构、信度、效标关联效度和聚合效度。在调查1（n = 216）中，进行了探索性因素分析（EFA），以检验强迫倾向量表的效标关联效度、聚合效度和信度。在调查2（n = 202）中，进行了验证性因素分析（CFA）。EFA和CFA采用了一个五因素结构，包括检查、条理、优柔寡断、清洁和强迫观念。与其他量表的相关性表明，强迫倾向量表具有有效的聚合效度、效标关联效度、内部一致性和重测信度。本研究验证了日本大学生强迫倾向的五因素结构。然而，优柔寡断也与特质焦虑密切相关。由于该量表易于在大群体中实施，它有可能通过测量过去未得到充分测量的日常强迫倾向，为大学生的心理健康支持做出贡献。
