While flooding or direct therapeutic exposure (DTE) has been empirical
ly validated as an effective primary treatment for PTSD through severa
l randomized controlled trials, there is also evidence that relatively
few trauma therapists actually use the technique. There are now sever
al published reports which document a number of the difficulties in im
plementing the treatment with chronic PTSD patients. These problems, r
anging from patient refusal to adverse reactions, represent several do
mains, including trauma history characteristics, patients' personal ch
aracteristics, therapist factors, and treatment environment factors. T
he purpose of the present report is to provide an empirical rationale
to support the use of individual flooding as a primary form of psychot
herapy for chronic combat-related PTSD. Implementation rates for flood
ing are compared among expert behavioural trauma therapists versus fie
ld use rates for trauma programmes generally. Complications or side-ef
fects of flooding are considered. We also identify several predictable
sources of difficulty in implementing individual flooding and the pro
portions of patients likely to be affected by each type. Finally, prac
tical suggestions are offered for improving utilization of flooding, a
nd directions for future empirical investigations are explored.
