The severity of obsessive compulsive symptoms (OCS) is suggested to be normally distributed in the general population, and they appear to have an impact on a range of aspects of adolescent development. Importantly, there are individual differences regarding susceptibility to OCS. In the present repeated measures study, OCS were studied in relation to gender and emotional stability (as a personality trait) using a normative sample of 515 adolescents at ages 16 and 18 years. OCS were assessed with the relevant subscale of the SCL-90-R and emotional stability with the Five Factor Questionnaire. A three-level hierarchical linear model was calculated to longitudinally assess the over time variations of OCS and their over time links to gender and emotional stability, while controlling for random effects due to the nesting of the data. Experiencing OCS increased with age (between 16 and 18 years). Additionally, male gender and higher emotional stability were associated with lower OCS at 16 years and these remained stable over time. Results indicate age-related and between individual differences on reported OCS that need to be considered for prevention and intervention planning.
强迫症症状（OCS）的严重程度在普通人群中呈正态分布，且似乎对青少年发育的一系列方面都有影响。重要的是，在易患强迫症方面存在个体差异。在本重复测量研究中，以515名16岁和18岁青少年的常模样本为对象，研究了强迫症症状与性别和情绪稳定性（作为一种人格特质）之间的关系。使用SCL-90-R的相关子量表评估强迫症症状，使用五因素问卷评估情绪稳定性。计算了一个三级分层线性模型，以纵向评估强迫症症状随时间的变化及其随时间与性别和情绪稳定性的关联，同时控制由于数据嵌套而产生的随机效应。经历强迫症症状的情况随年龄增长（在16岁至18岁之间）而增加。此外，男性和较高的情绪稳定性与16岁时较低的强迫症症状相关，且这些情况随时间保持稳定。结果表明，在报告的强迫症症状方面存在与年龄相关的以及个体之间的差异，在预防和干预规划中需要考虑这些差异。
