Hypnosis and rational-emotive therapy--a de-stressing combination: a brief communication.
It has been suggested that teacher stress might be reduced through cognitive restructuring which is aim ed at improving the rationality of their thinking . To test this hypothesis , 40 high school teachers were paired on their level of reasonable thinking , operationalized in terms of scores on the Teacher Idea Inventory ( Bernard , Joyce , & Rosewarne , 1983 ) , and allocated at r and om to one of 2 groups . They also completed the Face Valid Stress Test . The experimental group participated in 4 weekly treatment sessions involving a hypnotic induction and suggestions derived from key elements of Rational-Emotive Therapy . These focused on the reduction of what Ellis ( Ellis & Grieger , 1977 ) , the originator of this treatment , calls " irrational thinking . " The control group spent the same amount of time discussing stress reduction methods . Both the  Face Valid Stress Test and the Teacher Idea Inventory  were re-administered at the end of this period and again 12 months after conclusion of the experiment . Results indicated that both the experimental and control groups significantly reduced their levels of irrational thinking and stress , although the former 's improvement was more marked , particularly at the 12-month follow-up
