Abstract
Purpose: To determine the prevalence of post-traumatic stress disorder (PTSD), and the
extent of resilience among former national servicemen who had matriculated from a
Johannesburg high school from 1975 to 1988.
Design & Methods: A quantitative design which utilised an anonymous, internet-based
questionnaire accessed a sample of former national servicemen. Demographic data such as
year of intake to national service, current occupation, the type of service unit, combat
exposure, drug and alcohol use, exposure to other traumatic events, and recourse to
medication and counselling were obtained. The Impact of Event Scale –Revised (IES-R) was
used to measure prevalence of PTSD and the Connor Davidson Resilience Scale (CDRISC)
was chosen to provide a measure of coping. A sample of 109 men was traced out of a
possible population of 1527. They were contacted via email and invited to participate in the
anonymous web-based questionnaire. Data was processed from the Wits Health Sciences
website via a Microsoft Excel worksheet to the STATA version 11 statistical software
package and were subjected to regression analysis using the chi square test and
Spearman’s rho.
Results: The response rate was 49.5% of the sample of 109. The PTSD level in this sample
was 33% and was statistically significantly associated with combat exposure. There was no
association between the IES-R and the CD-RISC. Only 5.6% of respondents scored in the
range for PTSD on the CD-RISC suggesting high levels of resilience in this sample. Current
cannabis use was significantly linked with PTSD.
Conclusions. The PTSD prevalence in this population of former national servicemen is
higher than in comparable international studies. The primary care practitioner needs to
consider prior exposure to national service or combat in routine history-taking and to
consider PTSD when former national servicemen present with anxiety symptoms,
depression, somatisation disorder, irritable bowel syndrome, chronic pain or substance
abuse disorder.
