It is well established that the transition to new parenthood is associated with the onset or worsening of obsessive-compulsive symptoms (OCS); however, less is known regarding specific risk factors associated with the development of postpartum OCS. The present prospective study examined experiential avoidance and interpretations of intrusive thoughts as predictors of the development of postpartum OCS in first-time mothers and fathers. Participants were 64 expecting parents (33 mothers and 31 partners—all fathers) who were followed from the 2nd or 3rd trimester of pregnancy into the postpartum. All completed measures of postpartum OCS, experiential avoidance, and interpretations of intrusive thoughts. Experiential avoidance and the pre-existing tendency to misinterpret intrusive thoughts were predictors of infant-related OCS in the early postpartum, but not at six months postpartum. These findings provide support for particular psychological risk factors in the development of infant-related OCS among first-time mothers and fathers. Implications for prevention and intervention are discussed.

众所周知，过渡到新的父母身份与强迫症（OCS）的发作或恶化有关。然而，关于与产后OCS发展相关的特定危险因素的了解还很少。目前的这项前瞻性研究考察了经验性回避和对侵入性思想的解释，这些思想是对首次母亲和父亲产后OCS发生发展的预测指标。参加调查的有64位准父母（33位母亲和31位伴侣-均为父亲），他们从怀孕的第2个月或第3个月进入产后。产后OCS的所有已完成措施，体验避免以及对侵入性思想的解释。体验式回避和先前对误解性思想的误解是产后早期婴儿相关性OCS的预测因素，但不在产后六个月。这些发现为首次母亲和父亲中婴儿相关OCS的发展中特定的心理危险因素提供了支持。讨论了对预防和干预的意义。
