and their disability, which reflects the characteristics of having an internal locus of control. A study by Chung et al. (2006) focused on how the responses of spinal cord injury post-traumatic stress varied depending on age. The researchers tested different age groups including young adults, middle-aged, and elderly; the average age was 25, 48, and 65 for each group respectively. After the study, they concluded that age does not make a difference on how spinal cord injury patients respond to the traumatic events that happened. However, they did mention that age did play a role in the extent to which the external locus of control was used, and concluded that the young adult group demonstrated more external locus of control characteristics than the other age groups to which they were being compared.
