Eye movement desensitization (EMD) and a control procedure, image confrontation (IC) were compared in a group of 58 phobics, 31 of them arachnophobes. Subjects confronted disturbing images in a single-session crossover trial. Anxiety levels were recorded on the SUD Scale. Whenever practicable, SUDs to feared objects were also recorded. EMD and IC were equally effective in reducing anxiety levels. After 1 month, during which subjects were encouraged to use IC daily, improvement was maintained. Since exposure to the disturbing image is common to both methods it must be presumed to be the basis of change when EMD is used in cases of phobia.
