To be aware or not aware: Do intrusions with and without meta-awareness differ?

People sometimes re-experience traumatic events via intrusive memories that spontaneously and unintentionally intrude into consciousness (i.e., intrusions). Such intrusions can be experienced without explicit awareness (i.e., meta-awareness). However, we do not know whether intrusions with and without meta-awareness differ in how people experience them (i.e., characteristics) or react to them via maladaptive responses (i.e., suppression, negative interpretations), and therefore whether they are important to differentiate. To investigate this issue, we asked participants to watch a trauma analogue film and-during a subsequent unrelated reading task-intermittently probed them to capture and assess one film-related intrusion. Intrusion meta-awareness positively correlated with intrusion negativity, re-experiencing, and suppression, but not with how people interpreted the meaning of their intrusion. Our findings suggest intrusions with and without meta-awareness can differ in how they are experienced and associated with thought suppression-highlighting the importance of considering both types of intrusions in theory and practice.
