The influence of trauma symptoms on interpersonal attributions in daily life

There is well-documented evidence that trauma exposure can disrupt relationships. However, limited research has examined whether posttraumatic stress symptoms (PTSS) moderate interpersonal processes in daily life. To this end, undergraduates (N = 98) completed a measure of PTSS at baseline. They then completed smartphone-based surveys after every interpersonal interaction that lasted longer than 3 min. for 10 days. These surveys assessed perceptions of self and other agency and communion as well as feelings of rejection, neglect, abandonment, worthlessness, emptiness, guilt, and shame. Results of multilevel modeling suggest that interpersonal perception and PTSS predicted 10%-26% of the variance in outcomes. Regarding agency, more agentic participants reported higher levels of negative attributions, gamma s = .47-.56. Participants also reported higher rejection and guilt when they experienced their interaction partner as more agentic than usual, gamma s = .07, and PTSS did not moderate these associations. For communal perceptions, participants who experienced themselves and others as warmer than other participants reported fewer negative outcomes, gamma s = -.44--.58. Individuals also reported more negative outcomes when they experienced themselves and others as warmer than they usually did, gamma s = -.10--.28, and PTSS moderated these associations. The negative associations between self- and other communion ratings and feelings of neglect, abandonment, and shame were stronger in individuals with higher PTSS scores. Together, these findings support continued efforts to understand the ways in which trauma exposure and PTSS disrupt interpersonal dynamics in daily life.
