Habit control problems included smoking, nail-biting, and thumb-sucking with 7 college students as volunteer participants. A multiple baseline across subjects design was used. Subjects were randomly assigned to one of two treatments: contingent informal meditation or single session hypnosis. Contingent informal meditation combines behavioral strategies with meditation. The hypnosis condition involved one heterohypnosis session with instructions for self hypnosis. For contingent informal meditation, one subject achieved total cessation of smoking and one subject achieved total cessation of thumb-sucking. No hypnosis subjects achieved total cessation. Overall 5 of the 7 subjects, and all 4 of the Contingent Informal Meditation subjects experienced significant decreases in their habit.
