Background: Complex posttraumatic stress disorder (CPTSD) and posttraumatic stress disorder (PTSD) are prevalent among 3.4% to 7.7% of the general population (Cloitre et al., 2018). Interpersonal trauma perpetrated by a close other, also termed relational trauma, is a significant predictor of CPTSD (Fowler et al., 2013). Victims of relational trauma experience greater severity of posttraumatic stress symptoms compared to victims of non-interpersonal, such as a natural disaster or car accident (Seah & Berle, 2023; Fowler et al., 2013). The aim of this proposed study is to explore how cognitive flexibility, and posttraumatic cognitions mediate the relationship between one’s attachment style and perceived emotional invalidation and one’s symptoms of complex posttraumatic stress disorder. By examining this complex relationship, results may inform therapeutic treatment for individuals with relational trauma. Proposed Methods: Participants will be at least 18 years-old, reside in the United States, have had at least one romantic relationship for 6 months or longer, and have experienced difficulties or distress with at least one romantic partner. The survey will consist of five survey measures and demographic items. The data will be collected using Qualtrics and analyzed using SPSS.
