Abstract:

The present study investigates the effects of cognitive inhibitory mechanisms and tendency to suppress thoughts on the frequency and intensity of traumatic intrusions within the trauma film paradigm. Non clinical participants’ response inhibition and proactive inhibition levels and tendency to suppress thoughts were measured prior to exposure to a trauma film. One week after seeing the trauma film, participants reported the frequency and intensity of trauma film related intrusions with an intrusion diary and Impact of Events Scale. No significant effect of response inhibition, proactive inhibition and thought suppression tendency was found on the frequency and intensity of trauma film related intrusions. Findings of the study are discussed.
