A comparison of aggression, sensation seeking and positive and negative affection between people with Traumatic Brain Injury (TBI) and healthy people

The complex nature of traumatic brain injury and acute or long-term changes can dramatically affect quality of life after brain injury. Because many factors are involved in the etiology of traumatic brain injury, so the present study was done to compare sensation seeking, aggression, positive affect and negative affect in people with Traumatic Brain Injury (TBI) and healthy people
This study was causative-comparative. 30 people with traumatic brain injured and 30 healthy people were selected purposefully. For gathering data, it was used Zuckerman sensation seeking test, aggression questionnaire (AGQ), and positive affect and negative affect scale (PANAS). The data was analyzed by multi-variable variance analysis (MANOVA).
The results showed that the mean score of sensation seeking in individuals with brain injury was 22±4/48, and 11±4/48 in healthy subjects. The mean score of aggression was 54±9/95 in individuals with brain injury, and 33±9/42 in healthy individuals. The mean score of positive affect was 2±0/57 in individuals with brain injury and 3±0/52 in healthy people. The mean score of negative emotions in healthy individuals was 2±0/6, and 2±0/46 in people with traumatic brain injury. The results showed that the positive affect in people with brain injury is less than healthy subjects and patients with brain injury have more negative affect than healthy people.
It can be concluded that damage to the structure of the brain physiology will be followed by different psychological consequences, including aggression, sensation seeking and changes of affection.
