The behavioral treatment of auditory hallucinatory responding of a schizophrenic patient

This study assessed the efficacy of a behaviorally based treatment package to decrease the frequency of verbal responding to auditory hallucinations and to increase attention to important external stimuli, rather than to the hallucinations. The subject, a 49-year-old male, with a 20-year history of auditory hallucinatory responding (AHR), laughing and talking to himself, was seen in an outpatient clinic. Observations were made during management skill training, given usually twice a week. Observation sessions were divided into 15-minute intervals. The intervention package included reinforcement in the form of praise, pats on the back, and token reinforcement contingent on the absence of auditory hallucinations. Cancellation tests were given to measure his ability to attend to external tasks. Using an ABCAD design, it was seen that the data indicated that the intervention resulted in both a sharp decrease in auditory hallucinations and an increase in the subject's ability to attend to external tasks.
