Obsessive-compulsive disorder (OCD) commonly co-occurs with depression, resulting in heightened severity and poorer treatment response. Research on the associations between specific obsessive-compulsive symptoms (OCS) and depressive symptoms has utilized measures that have not fully considered the relationship across OCS dimensions. Little is known about which factors explain the overlap between OCS and depressive symptoms. OCS and depressive symptoms may be related via depressive cognitive styles, such as rumination or dampening (i.e., down-regulating positive emotions). We evaluated the associations of OCS dimensions with depressive symptoms and cognitive styles. We also examined the indirect effects of rumination and dampening in the relationship between OCS and depressive symptoms. Participants (N = 250) completed questionnaires online. Greater depressive symptoms, rumination, and dampening were associated with greater levels of all OCS dimensions. Path analysis was utilized to examine a model including the direct effect of depressive symptoms on overall OCS and two indirect effects (through rumination and dampening). There was a significant indirect effect of depressive cognitive styles on the relationship between OCS and depressive symptoms, through rumination and dampening. Replication in a clinical sample and experimental manipulations may bear important implications for targeting depressive cognitive styles in treatments for OCD and depression.
强迫症障碍（OCD）通常与抑郁症同时发生，导致严重程度增加和治疗反应不佳。关于特定的强迫症状（OCS）与抑郁症状之间的关联的研究，使用了没有充分考虑 OCS 维度之间关系的测量方法。对于哪些因素可以解释 OCS 和抑郁症状之间的重叠，人们知之甚少。OCS 和抑郁症状可能通过抑郁认知风格（如反刍或抑制（即，下调积极情绪））相关。我们评估了 OCS 维度与抑郁症状和认知风格之间的关联。我们还检查了在 OCS 和抑郁症状之间的关系中反刍和抑制的间接效应。参与者（N=250）在线完成了问卷。更多的抑郁症状、反刍和抑制与所有 OCS 维度的水平更高相关。路径分析用于检查一个包括抑郁症状对整体 OCS 的直接影响和两个间接影响（通过反刍和抑制）的模型。抑郁认知风格对 OCS 和抑郁症状之间关系的间接影响具有统计学意义，通过反刍和抑制。在临床样本中的复制和实验操作可能对 OCD 和抑郁症治疗中针对抑郁认知风格具有重要意义。
