Treatment of dental fears by imaginal flooding and rehearsal of coping behaviour

All combinations of high versus low arousal imaginal flooding, and coping versus no-coping imaginal rehearsal, were compared in the modification of dental fear. About one half of all subjects seen successfully completed dental treatment, although significant differences were found between groups in anxiety reduction before and during dental examination, which favoured the low arousal flooding groups. Coping rehearsal did not influence anxiety, but interacted with arousal level of flooding to determine subsequent dental attendance. The results suggest that flooding without coping rehearsal had little effect at high levels of arousal, but good results at low levels. Flooding with coping rehearsal on the other hand, had mixed results. At high arousal levels avoidance was reduced but not anxiety, while at low levels anxiety was reduced but not avoidance. The implications for further research on coping rehearsal are discussed.
