The authors compared 25 treated and 58 untreated subjects with simple
phobia uncomplicated by other lifetime anxiety disorders. The treated
individuals reported more phobias involving dogs and cats, elevators,
and transportation; most had multiple phobias; and many experienced pa
nic attacks in the context of their phobias. The untreated individuals
typically reported only one phobia, which was often related to blood-
injury and was seldom complicated by panic symptoms.
