An Experimental Investigation of the Interaction between Hypnotic Responsiveness and Type of Esteem Suggestion on Self-Concept

Abstract
Fifty-two volunteer subjects recruited from the University of British Columbia student population were hypnotized and administered combinations of self- and other-esteem suggestions to investigate the interaction between measures of hypnotic responsiveness and type of esteem suggestion on self-concept. A regression approximation of analysis of covariance was used to compare differences among grups. Although the lack of a placebo or classical control condition limits interpretation of results, the study indicates that hypnosis may be used effectively to improve the self-concept of susceptible university students. Susceptible subjects made significant improvements in self-concept after four sessions of hypnotic treatment utilizing Hartland''s (1971) Ego-Strengthening Technique. The two aspects of self-concept which were most responsive to treatment were self-satisfaction and personal self-concept.
