M.Fam.Med., Faculty of Health Sciences, University of the Witwatersrand, 2011 / 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.

Boredom is a common human experience, yet little is known about its underlying neural mechanisms. This thesis first set out to investigate the construct of boredom and more closely examined its relationship to phenomenologically similar mood states of depression, apathy and anhedonia. Next, deficits in sustained attention, and novelty seeking were examined in patients with traumatic brain injury (TBI), who are characterized by atypically high levels of boredom. Study 1 established that although related to varying degrees to apathy, anhedonia, and depression, boredom is indeed a distinct emotional experience. Furthermore, two boredom proneness subtypes - agitated and apathetic - were identified which varied in their relationships to depression. The relationship between boredom and depression was found to be high only in the agitated boredom prone subtype, which is characterised by a high degree of motivation to engage in meaningful, stimulating activities despite the fact that all attempts to do so fail to satisfy. In Study 2, the relationship between boredom proneness and depression was found to be greater in TBI patients than in healthy controls. Using a behavioral measure of sustained attention (SART; Robertson et al., 1997), Study 3 demonstrated a relationship between boredom proneness and sustained attention in healthy controls, such that RTs were faster and commission errors more prevalent in the agitated boredom prone subtype. No relationship between boredom proneness and sustained attention was found in TBI patients. So while attention and boredom show a clear relationship in the healthy brain, this relationship may be disrupted in TBI patients. Finally, Study 4 demonstrated an association between agitated boredom proneness and a preference for novel stimuli across participant groups. In addition, patients had a poorer ability to discriminate between similar and dissimilar stimuli than controls, which was more evident in the agitated boredom prone group. It may be the case then that agitated boredom prone individuals fail to satisfy their desire to engage in stimulating activities in part because they fail to accurately identify when something is indeed novel. Taken together, these results highlight important distinctions between apathetic and agitated boredom proneness, and the way in which these subtypes relate to depression, attention, and novelty seeking, in brain injured patients and healthy controls. More work is needed to determine the role played by boredom in TBI, particularly as this evolves from acute to chronic stages of the illness. Importantly, identifying boredom as a key element in depressive mood disorders, attention deficits (e.g., attention deficit hyperactivity disorder), and novelty seeking behaviour, facilitates the design and implementation of appropriate intervention strategies. For example, it will become increasingly important to deal with boredom as a significant component of depression. Thus, the work presented here represents a novel and important contribution to the study of boredom in that it brings the field one step closer to understanding and treating the experience. Further investigation with greater numbers of patients is necessary to fully explicate the relationship between boredom and depression, attention, and novelty seeking in TBI.

The present study was carried out to examine long-term psychological difficulties associated with war experience. 731 World War Two and Korean War veterans completed a questionnaire supplying biographical details, war-related experience, and present day psychological health. A significant proportion had war-related psychological difficulties, these problems correlating more strongly with war-related intrusive thoughts and avoidance than with actual combat experiences. A subgroup of 25 veterans were selected for depth interview. The results of these interviews supported the finding that many veterans have war-related problems, and that they related more to intrusion and avoidance than to actual experiences. For some veterans these problems have been present since the war, but for many they only started after retirement, when they have had more time to think about their past experiences. The problems include nightmares, intrusive thoughts, depression and anxiety. Coping is expressed by these veterans in terms of a) developing a narrative about their experiences which allows them to consciously control their traumatic recollections, or b) avoidance, where veterans avoid potential stimulus material, eg war films. Other forms of coping such as social support are secondary. Even after 50 years, veterans still experience traumatic recollections, memories which, to them at least, are accurate and detailed pictures of the events that occurred. The findings are explained in terms of a theoretical model which examines the role of traumatic recollections as conditioned responses that are out of conscious control, and likely to emerge into consciousness when the veteran is reminded of the war through some stimulus, eg the anniversary of a battle. Implications for post-traumatic stress disorder, ageing, and treatment models are considered.
