potentially traumatic incidents impacts on the South African Emergency Care Practitioner
(ECP). The study sought to investigate the presence of symptoms of posttraumatic stress
(PTS) in the sample and the events which appear to pose the greatest threat to these
ECPs mental health. The notion that individuals exposed to the same traumatic stressors
can present with very different posttraumatic responses has led to the acknowledgement
that the relationship between exposure and PTS is a complex one. Studies have examined
a multitude of variables believed to impact in some way on this relationship, with
particular emphasis on individual appraisals and coping styles. Less attention has been
afforded the role of social phenomena in the development of posttraumatic stress disorder
(PTSD). The attention that has been afforded these phenomena has tended to examine
social support as a unidimensional construct, and studies have often measured different
social support conceptualisations. Utilising a recognised psychosocial framework, the
present study sought to investigate the impact of social support in the relationship
between exposure and PTS. It sought to examine three distinct facets of social support,
namely: the appraisal of being supported, the perception of available supportive
behaviours from family and friends, and an individuals orientation towards utilising
support. The study used a cross-sectional, correlational design to investigate the
relationships between exposure, PTSD symptoms and social support. The procedure
involved the anonymous completion of several standardised self-report measures by 107
ECPs from Netcare 911, a private South African emergency care organisation. These
measures included a revised version of the Paramedic Work Exposure Checklist (PWEC),
the Revised Impact of Event Scale (RIES), the Social Support Appraisals Scale (SS-A),
the Social Support Behaviours Scale (SS-B) and the Network Orientation Scale (NOS).
The events that tended to be rated as having the most negative emotional impact among
respondents involved assisting abused or injured children, witnessing the death or injury of a
coworker, assisting victims of sexual assault, dealing with equipment failure or the
incompetence of others and receiving inadequate or incorrect information when dispatched on a call. The correlational analyses revealed that exposure to events rated as having a
negative emotional impact was significantly and positively associated with symptoms of
PTSD in the sample. Correlational analyses also revealed that each of the facets of social
support measured was significantly negatively associated with symptoms of PTSD. The
results indicate that the mode and source of support most significantly associated with
symptoms of PTSD in the sample was the perception of available emotional support from
friends. In spite of the direct relationships observed between symptoms of PTSD and the
facets of social support examined, none of the social support facets investigated emerged as
a significant buffer in the relationship between exposure and PTSD. The study highlights the
need for additional research, including longitudinal investigation, into the role of multiple
facets of social support in the relationship between exposure and PTSD. Some suggestions
for future research and the practical application of the findings of the research are offered.
