Relationships Between Childhood Experiences, Threat Responding, and Posttraumatic Stress

Abstract

Early childhood encompasses critical stages of cognitive development, and a child’s attachment to their caregivers plays a vital role. Traumatic, stressful, and unpredictable experiences with caregivers in childhood can shape how an individual responds to threats and potentially lead to mental health difficulties. There are three key elements of threat responding: fight, flight, and freeze. It is common for individuals to freeze when they first detect a threat and then prepare to deal with it by either fighting or fleeing the situation. However, in some threatening situations, freezing may persist. We refer to this prolonged freeze response as “tonic immobility”. Individual differences in threat responding, and tonic immobility specifically, have been linked to increased risk for posttraumatic stress disorder (PTSD). Therefore, the current study sought to examine the relationships between childhood experiences, threat responding, and PTSD. Female participants (N = 35) were recruited from the FSU SONA subject pool and the local community. As part of a larger experimental study, participants provided informed consent and completed questionnaires assessing demographic information, adverse childhood experiences, childhood unpredictability, and harshness, fight flight freeze tendencies, experiences of tonic immobility, and PTSD symptoms. Correlations suggest that adverse childhood experiences, unpredictability, and harshness are associated with experiences of tonic immobility and PTSD symptoms. However, only childhood unpredictability was uniquely related to tonic immobility. Meanwhile, childhood harshness uniquely predicted flight tendencies. Experiences of tonic immobility and freeze tendencies predicted higher PTSD symptoms. These findings provide evidence for the impact of childhood experiences on threat responding and PTSD.
