Compulsive sexual behavior disorder (CSBD) was previously considered an attachment disorder, while emotion dysregulation was thought to potentially be a key characteristic of it. However, this theoretical model was not tested in previous empirical research. In our cross-sectional study, we tested whether emotional regulation (ER) difficulties can be adopted as an explanatory mechanism for the relationships between attachment avoidance and anxiety, as well as CSBD and its most prevalent behavioral presentation—problematic pornography use (PPU). Participants (n = 1002; M_age = 50.49 years, SD = 13.32; men: 50.2%) completed an online survey regarding the investigated variables. In mediation analyses, attachment avoidance and anxiety were treated as simultaneous predictors, ER difficulties as a mediating variable, with CSBD/PPU severity as dependent variables. Emotion regulation difficulties and attachment anxiety had a direct positive effect on both CSBD and PPU. The direct effect of attachment avoidance on PPU was non-significant, and significant for CSBD depending on the measure used. Moreover, all the relationships between both insecure attachment dimensions and CSBD/PPU symptom severity were at least partially mediated by ER difficulties. Our results corroborate the theoretical claim that ER difficulties may be a useful framework for explaining the impact of attachment insecurity on CSBD/PPU. Theoretical and practical implications of the findings are discussed.

强迫性行为障碍（CSBD）以前被认为是一种依恋障碍，而情绪失调被认为可能是其一个关键特征。然而，这一理论模型并未在之前的实证研究中得到检验。在我们的横断面研究中，我们测试了是否可以采用情绪调节（ER）困难作为依恋回避和焦虑之间关系的解释机制，以及CSBD及其最普遍的行为表现——有问题的色情内容使用（PPU）。参与者（n = 1002；M _age = 50.49 岁，SD = 13.32；男性：50.2%）完成了有关调查变量的在线调查。在中介分析中，依恋回避和焦虑被视为同时预测因子，ER 困难作为中介变量，CSBD/PPU 严重程度作为因变量。情绪调节困难和依恋焦虑对CSBD和PPU都有直接的积极影响。依恋回避对 PPU 的直接影响并不显着，而对 CSBD 的影响则显着，具体取决于所使用的措施。此外，不安全依恋维度与 CSBD/PPU 症状严重程度之间的所有关系至少部分是由 ER 困难介导的。我们的结果证实了理论主张，即 ER 困难可能是解释依恋不安全感对 CSBD/PPU 影响的有用框架。讨论了研究结果的理论和实践意义。
