Abstract

Post-traumatic stress disorder (PTSD) and post-traumatic growth (PTG) are two different outcomes that may occur after experiencing traumatic events. Meanwhile, the traumatic exposure level and emotion response played an important role in the process. The present study first evaluated the relationship between PTSD, PTG, and traumatic exposure level and then compared the characteristics of emotional response through response time of the affective priming paradigm. For the purpose of evaluating the relationship between PTSD, PTG, and trauma exposure level, a sample of 2,395 participants completed measures of posttraumatic stress disorder Checklist-Civilian Version (PCL-C), Post-traumatic Growth Inventory (PTGI) and a trauma exposure-related survey, and Pearson's correlation analysis for the scales were conducted. In order to compare the characteristics of emotional response between PTSD and PTG, we randomly selected 90 participants and divided them into groups of PTSD, PTG, and control according the scores of PCL-C and PTGI, then the 90 participants were asked to do the affective priming task and the response time was recorded, at last analysis of variance was employed to analyze the data. The results indicated that PTSD was not correlated with PTG. It was positively correlated with the traumatic exposure level, but PTG was not observed in this phenomenon. Finally, the data of response time showed that PTSD required more time to do the priming task and PTG demonstrated no difference compared to the control group. Combined with previous research findings, the relationship between PTSD and PTG may depend on the type and severity of the trauma, the exposure level, and other such parameters. In terms of positive outcome of trauma PTG displayed no changes of emotional performance from the perspective of behavior. The preliminary results suggested that PTG was more related to a self-reported or self-experienced state.

Highlights

Life-threatening illnesses and events such as earthquakes, motor vehicle accidents, or terror incidents may cause posttraumatic stress disorders (PTSD) and post-traumatic growth (PTG) [1,2,3,4,5]
The results indicated that PTSD ChecklistCivilian Version (PCL-C) negatively correlated with Post-traumatic Growth Inventory (PTGI) (r = −0.05, p = 0.04), the correlation coefficient was generally weak
Several studies focused on the relationship between PTG and PTSD and reached different conclusions, some held the point of view that there was a positive correlation, while others suggested that there was a negative correlation between them

Summary

Introduction

Life-threatening illnesses and events such as earthquakes, motor vehicle accidents, or terror incidents may cause posttraumatic stress disorders (PTSD) and post-traumatic growth (PTG) [1,2,3,4,5]. Since the development of a new chapter in DSM-V on trauma- and stress-related disorders, much more attention has been paid to the emotional symptoms that accompany PTSD. PTG refers to the experience of positive change that occurs as a result of the struggle with highly challenging life crises, describing the experience of individuals who do recover from trauma and discover it as an opportunity for further individual development. Those individuals overcome trauma with improved psychological functioning in specific domains [7]. PTG has been reported by a significant number of people who have encountered major life challenges, resulting in such factors described as new possibilities, relating to others, personal strength, spiritual change, and appreciation of life [8]
