Thesis Abstract: 
TJ's honors thesis will investigate the role of decreased expression of emotion, or emotional inexpressivity, in the relationship between posttraumatic stress disorder (PTSD) and intimate partner violence (IPV) perpetration. This project stems from prior work indicating that emotional inexpressivity is associated with higher PTSD symptoms (Moore, Zoellner, & Mollenholt, 2008) and higher levels of relationship aggression (Maldonado, DiLillo, & Hoffman, 2014; Tull et al., 2007). Moving past a dichotomous perspective of IPV perpetration, he hopes to build upon this prior research by examining both individual and partner characteristics among this relationship to understand how both partners' inexpression could predict IPV within the context of PTSD. His investigation will come from a study of rural community couples in which at least one partner met screening criteria for probable PTSD. By coding the quality of emotional inexpression among videotaped discussions regarding relationship issues between couples, his work aims to understand how emotion is operating at the communicative level in potentially influencing IPV perpetration. An additional focus of the project is to elucidate how these interactions may differ by gender. Overall, the goal of this research is to identify an important component of communication in relationships to better inform treatment approaches and prevention efforts in targeting particularly harmful and costly consequences of PTSD.
