Da. Grayson et al., AUSTRALIAN VIETNAM VETERANS - FACTORS CONTRIBUTING TO PSYCHOSOCIAL PROBLEMS, Australian and New Zealand Journal of Psychiatry, 30(5), 1996, pp. 600-613
Objective: The objective of the present paper is to present comprehens
ive models of the current psychosocial morbidity of Australian Vietnam
veterans. Seldom has research in this area attempted to 'untangle' di
rect and indirect influences on current functioning via possible pre-a
rmy, Vietnam and homecoming pathways. Method: The Australian Vietnam V
eterans' Health Study gathered data on a sample of 641 veterans throug
hout Australia drawn randomly from army Vietnam tour lists of the era.
The data arose from interview and army records of the era, and fall i
nto four temporal categories: pre-army, Vietnam service, homecoming af
ter Vietnam, and current state. Path analysis models of the veterans'
current psychological morbidities and social wellbeing are used to ide
ntify direct aetiological influences of earlier era constructs on curr
ent state, free of confounding by indirect (often selection) effects.
Results: Our results indicate that psychological morbidity (particular
ly posttraumatic stress disorder) is largely influenced by combat and
poor homecoming experiences, although pre-military characteristics do
play some direct roles in symptomatology. Social dysfunction measures
show smaller effects of the Vietnam War, which may be accounted for by
an indirect association with Vietnam-related psychological morbidity.
Some social measures show evidence of compensatory influences of comb
at, high combat leading to social dysfunction because of morbidity, bu
t simultaneously being associated with healthier social disposition (p
ossibly because of increased ex-service activity). Conclusions: For Au
stralian Vietnam veterans, combat-related and homecoming effects persi
st on a range of psychosocial endpoints 20-30 years after exposure. Th
ese effects are not explicable in terms of veterans' pre-Vietnam chara
cteristics.
