Although disgust proneness has been implicated in the development of obsessive-compulsive disorder (OCD), available studies have largely employed cross-sectional designs and the prospective and potentially reciprocal association between disgust proneness and OCD symptoms remains unclear. The present study employs cross lagged panel analysis to examine the prospective and reciprocal association between disgust proneness and OCD symptoms.
A community sample of adults (N = 307) completed symptom measures of disgust proneness and OCD symptoms at four time points with 1 month intervals.
The results showed that the cross-lagged paths from disgust proneness to OCD symptoms were significant (average β = 0.07, p's < 0.001) when controlling for depression. However, the paths from total OCD symptoms to disgust proneness were not significant. In contrast, the cross-lagged paths from disgust proneness to washing OCD symptoms were not significant. However, the paths from washing OCD symptoms to disgust proneness were significant (average β = 0.05, p's < 0.01) when controlling for depression.
The study is limited is limited by exclusive reliance on self-report in a nonclinical sample.
The findings offer preliminary evidence suggesting that disgust proneness may be a cause and consequence of OCD depending on the nature of the symptoms. Thus, the longitudinal relation between disgust proneness and OCD may be transactional where one influences the effect of the other.
虽然易恶心倾向与强迫症（OCD）的发展有关，但现有研究大多采用横断面设计，易恶心倾向与 OCD 症状之间的前瞻性和潜在的相互关系尚不清楚。本研究采用交叉滞后面板分析来检验易恶心倾向与 OCD 症状之间的前瞻性和相互关系。
一个社区成年人样本（N=307）在四个时间点完成易恶心倾向和 OCD 症状的症状测量，间隔为 1 个月。
结果表明，在控制抑郁的情况下，易恶心倾向对 OCD 症状的交叉滞后路径是显著的（平均β=0.07，p<0.001）。然而，总 OCD 症状到易恶心倾向的路径并不显著。相比之下，易恶心倾向对洗涤 OCD 症状的交叉滞后路径不显著。然而，在控制抑郁的情况下，洗涤 OCD 症状到易恶心倾向的路径是显著的（平均β=0.05，p<0.01）。
该研究的局限性在于仅依赖于非临床样本中的自我报告。
这些发现提供了初步证据，表明易恶心倾向可能是 OCD 的一个原因和后果，这取决于症状的性质。因此，易恶心倾向和 OCD 之间的纵向关系可能是相互影响的，一个影响另一个的影响。
